How much of an event's profit should you reinvest?

You've settled the event, paid the people who delivered it and finally have a result you're happy with. Now you're looking at next year's venue, a better launch campaign and the money you'd quite like to take home. How much should stay in the business?

Reinvest the amount you can afford in specific improvements that have a credible commercial purpose. First confirm the profit, cover existing commitments and decide how much cash the business needs to keep available. Then compare the proposed improvements with paying some profit to the owners or leaving the money uncommitted. The right percentage comes out of those decisions.

I wouldn't start with a rule to reinvest half, or everything, or whatever another organizer says they do. Those rules tell you nothing about your next deposit, your exposure if a date falls through or whether the proposed spending will help. An event can need more retained cash without needing a bigger production budget.

We'll work through a fictional business with $40,000 available for allocation, compare two investments and test what happens when the next edition is weaker. Every financial figure in the examples is invented and uses USD. These are planning calculations, not industry benchmarks, tax rates or customer results. You'll finish with a decision record you can use after your own settlement.

Agree what you mean by reinvesting profit

Keeping money in the business and spending it on growth are different decisions. You can retain a surplus without immediately buying anything. That money might protect payroll between dates, help fund the next venue deposit or remain available while you investigate a new format.

For this article, reinvestment means an additional commitment intended to improve the business. It could be a better sales process, equipment, staff training or a carefully tested extra date. Holding cash for uncertainty is a reserve decision. Funding delivery you've already agreed is an existing commitment. All affect what you can spend, but they answer different questions.

That distinction matters when somebody says they reinvest all their profit. Do they mean they take no ownership distribution? Do they spend the entire amount on another event? Or do they leave it available in the account? You can't judge the policy until you know which of those actually happens.

Separate ordinary delivery costs too. Paying the venue for next year's confirmed event isn't automatically an improvement to the business. It may simply fund the same operation again. Replacing an essential piece of failed equipment may be necessary to continue delivering the offer you've sold, regardless of whether it produces extra ticket income.

Put compulsory work into the baseline budget before ranking optional projects. Required safety measures, accessibility provision and obligations to buyers don't compete with an advertising experiment for whatever happens to remain. If the ordinary event can't fund the necessary delivery, revisit the event's feasibility.

Now you can ask a more useful question. After funding what the business already owes and needs, which additional uses of the surplus are worth approving? You might decide to improve the event, build reserves and pay an owner distribution in the same review. None needs to consume the entire amount.

Confirm the result before allocating it

Start with a settled profit calculation. Check ticket revenue after refunds, sponsor income earned, final supplier costs, staffing, marketing and the shared business costs attributable to the period. Include the cost of your work in the commercial assessment, even where your business structure records owner payments differently.

If the event looks profitable only because you've left out months of your own work, you haven't established the surplus you think you have. Our guide to including your own time in an event budget develops that calculation. Regular compensation for doing the job needs its own plan before an additional ownership return.

Ask what is still provisional. A production estimate isn't a final invoice. A disputed supplier charge doesn't disappear because you disagree with it. An unresolved refund or sponsor delivery obligation may change the result. Record the uncertainty and the basis for any allowance, with your accountant's help where the accounting requires it.

Use the same basis across dates. If one event result includes shared marketing costs and another doesn't, comparing their surpluses can send investment towards the wrong format. The event profit and loss template helps you assemble a consistent view before deciding what to fund next.

Then reconcile profit with cash. Unpaid sponsor income can appear in a result before payment arrives. A loan can increase the bank balance without creating profit. Buying equipment, repaying loan principal and recognising depreciation can affect cash and profit at different times. You need both records to understand the amount available.

Australia's business.gov.au guide to managing cash flow recommends forecasting receipts and payments, accounting for seasonal changes and setting money aside for ongoing obligations. Apply that discipline to the allocation review. The source provides Australian business guidance; it doesn't prescribe a reinvestment percentage for event operators.

Finally, identify the period and the tax basis of the number you're allocating. A single event's contribution before annual overhead isn't the same as the company's annual profit after tax. Write the description beside the amount. A precise percentage calculated from the wrong starting figure is still the wrong decision.

Work out how much cash is available for a new decision

Let's make the example concrete. Our fictional company runs a recurring paid event. Its reviewed accounts show $40,000 profit after all applicable costs, regular owner compensation and the company income tax charge for the period. Its adviser has confirmed the position used for this exercise. Personal tax on any later ownership payment is separate.

The company has $78,000 in its bank account. That balance includes money carried forward from earlier activity. It has $18,000 of identified unpaid obligations, including tax and settled supplier bills, and needs $8,000 for an existing next-edition commitment. Those amounts don't overlap.

It also has an existing policy to keep $12,000 available after those payments. That minimum was chosen for this fictional business. It isn't a statutory requirement or a recommended amount for yours. We'll consider an additional reserve contribution shortly.

The cash calculation is:

• Current bank balance is $78,000.

• Existing unpaid obligations require $18,000.

• The already agreed next-edition commitment requires $8,000.

• The existing minimum cash balance protects another $12,000.

• That leaves $40,000 for the new allocation decision.

The available cash and the period's after-tax profit happen to match in this example. They needn't match in your business. The cash calculation doesn't derive profit from the bank balance. Nor does subtracting unpaid tax here charge it twice to profit. Its expense is already recognised in the accounts; this calculation identifies the cash still needed to pay it.

Check the payments by date before relying on the remaining amount. Money that looks available at the end of a quarter may be needed earlier. Our event cash-flow forecast guide shows how to check those dates. Here, we're deciding what to do with the amount that survives that forecast.

Also check any restrictions attached to the funds. Advance ticket receipts, grants, borrowing and partner arrangements may carry obligations or conditions. A cleared bank receipt doesn't establish unrestricted spending authority. Keep the relevant agreements with the review, rather than assuming the label on the bank account answers the question.

Build the reserve around the event's actual exposure

Before choosing an upgrade, ask what could force the business to spend money before it receives dependable replacement income. Your answer might include a delayed sponsor payment, a cancelled date, an urgent supplier replacement or the quiet period between annual editions.

A reserve needs a reason. A general preference for having more money available is understandable, but it doesn't tell you when the amount is sufficient. List the situations you're protecting against, the payments they create and the other receipts or recoveries you could actually rely on.

Business Queensland's financial risk guidance identifies seasonal cash exposure and the risk of paying for growth before its revenue arrives. It recommends examining possible situations and planning how to meet obligations. For an event business, that means testing the particular calendar and contracts behind your reserve choice.

Start with separate scenarios so you understand each one. A late sponsor payment may create a temporary gap. A cancelled show may remove revenue and leave unrecoverable costs. They aren't interchangeable. Then combine the situations that could reasonably happen together, rather than assuming every risk is independent or every worst case must occur simultaneously.

Keep known bills out of the emergency calculation if they've already been funded. Our example's $18,000 of obligations and $8,000 commitment are already protected. Adding them again to the reserve would understate available money. Equally, don't treat the existing $12,000 minimum as covering every possible loss without checking what it was meant to cover.

The fictional company now tests a supplier failure that would require $14,000 of additional replacement services and $8,000 of additional paid crew support. Both are costs beyond the original delivery budget. Assume no supplier refund or insurance recovery would arrive before those payments fall due. This separate reserve-setting scenario therefore needs $22,000 beyond the already funded obligations.

It decides to increase its protected minimum from $12,000 to $22,000. The new allocation therefore needs a $10,000 reserve contribution. These invented amounts explain how to build the calculation. They don't estimate the cost of a supplier failure at your event or establish cover for a cancellation.

In your own review, build that amount from the actual exposure. Include refund timing, supplier terms and any gap before an insurer or other party pays. An expected recovery can reduce an eventual loss while still arriving too late to meet the first payment. Confirm the terms and dates before relying on it.

Record when the reserve can be used and who approves using it. It should be accessible when the named problem occurs. Also agree how to replenish it afterwards. Otherwise, a one-time withdrawal quietly becomes the new normal, and next year's allocation starts from a level you never deliberately accepted.

Allocate the surplus without spending every dollar

The company has $40,000 available for a fresh decision and has chosen a $10,000 reserve contribution. That leaves $30,000 to consider for improvements, an ownership return or continued flexibility. It doesn't need to find a project for all $30,000.

After reviewing its options, it proposes this allocation:

• Add $10,000 to the reserve, raising the protected balance to $22,000.

• Approve up to $12,000 for two defined improvement projects.

• Consider a $6,000 ownership distribution, subject to the required checks and approvals.

• Leave $12,000 uncommitted until a later review.

Those four amounts total $40,000. The reserve contribution is 25% of the allocation, the projects are 30%, the proposed distribution is 15% and the uncommitted amount is 30%. These percentages describe the fictional decision. They aren't recommended targets.

Here's the interesting part. The company is committing 30% to improvements while leaving 85% inside the business at the point of the proposed owner payment. Those are compatible statements. The $34,000 not distributed includes the reserve contribution, the project budget and the uncommitted amount. Some of it will later be spent.

This is a cash allocation record, not a prediction that the next accounts will show $34,000 of additional retained profit. Future project spending has its own accounting treatment. Some costs may be expenses, while a qualifying asset purchase may be treated differently. Have your accountant record the actual transactions appropriately.

Leaving money uncommitted is a deliberate option. The business may be waiting for a venue quote, evidence from its next release or the result of a small test. Write down what information you're waiting for and when you'll review it. That makes a pause useful without turning it into indefinite indecision.

Check the whole allocation against the bank balance as well. After the $18,000 obligations and $8,000 commitment, $52,000 remains. That consists of the existing $12,000 minimum plus the new $40,000 allocation. You haven't created another reserve by describing the same balance twice.

Compare improvements by the problem they solve

Now make the proposed $12,000 work harder. Before asking which project is most exciting, identify where the existing event loses money, wastes paid time or disappoints buyers in a way you can fix. Use settlement records, delivery notes and actual audience behaviour.

A larger production spend may be appropriate if it resolves a documented problem with the paid experience. It needs a more specific explanation than making next year's event bigger. If buyers couldn't hear a workshop, solve the audio problem. If the ticket offer was unclear, adding stage lighting won't explain it.

For each proposal, describe what changes and who benefits. Then explain how that change could improve the business. It might reduce a recurring supplier bill, release producer time, support repeat purchases or let you deliver a format that already has credible demand. Keep the operational change connected to the commercial result.

Compare it with a smaller alternative. Could hiring equipment solve the problem before buying it? Could a clearer event page answer buyer questions before you commission a full redesign? Could one additional paid contractor day remove a bottleneck before you create a permanent role?

Include the work needed to make the investment useful. Equipment needs transport, storage, maintenance and a capable operator. A new sales process needs setup and ongoing attention. A new date needs a programme, promotion and someone available to deliver it. The purchase price alone doesn't represent the commitment.

Separate cash savings from time released. If you save ten hours of an owner's work but pay the same salary, you've gained capacity without necessarily reducing payroll. That can still be valuable. Name the work those hours will now support, rather than adding an imaginary cash saving to the bank forecast.

Finally, check what happens if you do nothing this season. Some problems get more expensive or make continued delivery unacceptable. Other ideas can wait without damaging the offer. That difference helps you choose between a necessary correction, a credible improvement and an attractive project whose benefit remains unclear.

Test the return with a worked equipment decision

Our fictional company is considering equipment used at several editions. The proposed purchase and setup cost $9,000. The team estimates that each delivered event would avoid $1,000 of hire costs but create $250 of extra transport, maintenance and operating cash costs. The net saving would therefore be $750 per use.

Assume those figures include all project-specific cash costs for this simplified comparison. They exclude financing, income tax effects and resale proceeds. There is no extra unpaid work hidden in the estimate. A real proposal needs the actual quotes, staffing plan and tax treatment, including any recoverable sales tax.

At $750 saved per delivered event, recovering the $9,000 initial cash outlay requires twelve uses. If the company delivers six suitable events a year, that takes two years. Four suitable events a year extends it to three years. The equipment doesn't recover its cost faster just because more dates appear in an ambitious business plan.

The Business Development Bank of Canada's guide to evaluating investment projects explains this payback approach and its limits. It doesn't allow for the value of receiving money sooner or count cash flows after the initial outlay is recovered. For a substantial or long-lived purchase, have your adviser assess the wider financial case too.

Use the calculation to challenge the assumptions. Are the six events confirmed? Can the equipment serve each venue? Will hiring really disappear, or will you still need a specialist supplier? If an existing supplier package includes crew and backup, compare the replacement service properly before calling the entire package an avoided cost.

Check the downside. If only eight suitable events are delivered before the equipment becomes unusable, the assumed savings total $6,000. With no resale or other recovery, $3,000 of the initial outlay remains unrecovered. That isn't a forecast of failure; it's a test of how much continuing use the purchase needs.

Also check the available cash. The full $9,000 leaves before those savings accumulate. It can be an attractive long-term purchase and still be the wrong commitment before a tight deposit period. Our equipment hire-versus-buy guide explores that decision in more detail.

Fund an audience experiment in stages

The other proposed project uses $3,000 to improve repeat-buyer promotion across the next season. That budget includes the specific setup, creative, sending and paid staff costs chosen for this fictional test. Existing general overhead is unchanged. The objective is to find out whether a better invitation and offer produce additional paid attendance profitably.

Suppose each genuinely additional ticket sale that remains after refunds leaves $30 after payment costs and every extra delivery cost caused by the sale. We'll call those retained sales. The project then needs 100 additional retained ticket sales to recover its $3,000 cost. At 140 such sales, the contribution is $4,200, leaving $1,200 after the project cost, before income tax and unchanged wider overhead.

At 60 additional retained sales, the contribution is $1,800 and the project falls $1,200 short. Those outcomes use chosen assumptions. They don't establish that this audience exists, that the sales are additional or that the event has capacity to serve them without another fixed cost.

A reported campaign sale isn't automatically an additional sale. Some previous buyers would have returned anyway. Someone may click an email and later buy for unrelated reasons. Define how you'll compare the campaign with ordinary demand, and be honest about what a small test can establish.

Where practical, compare similar groups or releases while recording other changes. Don't undermine a promised presale or exclude people from necessary event information to create a test. If the comparison can't show that the campaign caused the extra purchases, report the observed sales and the uncertainty separately.

Loopyah's attendee email tools let you build campaigns for past buyers and review tickets and revenue associated with them. That helps you see what happened after a send. You still need to assess whether the purchases were additional and whether the resulting contribution covered the full project cost.

You can approve the $3,000 ceiling while releasing only an initial $1,000. Define the evidence required before committing the remaining $2,000. Under the same $30 contribution assumption, the first stage needs 34 additional retained sales to exceed its cost. At 34, it produces $1,020 of contribution, leaving $20 before the excluded items.

That isn't an automatic scaling rule. The later audience may respond differently, and a larger campaign can create new costs. Use the first stage to revise the next decision. If it doesn't work, record what you learned and stop the uncommitted spending rather than treating the original approval as an obligation to use it all.

Check the combined plan against a weaker season

Two projects can each look manageable and still be too much together. Our company proposes $9,000 for equipment and up to $3,000 for promotion. Add the $6,000 ownership payment and the $10,000 reserve contribution, and the allocation leaves $12,000 uncommitted.

Put the actual project and distribution dates into the company forecast. Keep the extra reserve protected, and include all committed event delivery. Then test a season with fewer suitable equipment uses, slower sales and a delayed receipt. Our event budget scenario guide explains how to connect changed sales assumptions with the costs they alter.

For this separate timing test, assume the original future forecast leaves the full $12,000 uncommitted above the $22,000 protected balance at its tightest point, after all scheduled payments. That condition matters. The allocation total alone doesn't establish the lowest balance during the season.

Now suppose a separately forecast $9,000 sponsor receipt arrives after the planned equipment payment rather than before it. Every other receipt and payment stays unchanged. The $12,000 of uncommitted cash could cover that temporary difference and leave $3,000, while preserving the chosen reserve and other funded commitments.

Now suppose the same period also requires a new $5,000 payment that wasn't in the baseline. Together, the changes require $14,000. The uncommitted amount covers only $12,000, so the plan needs another $2,000 or a genuine change to spending or timing. A positive expected year-end profit doesn't close that immediate gap.

This is the value of checking before approval. You can defer the equipment, reduce an uncommitted test or reconsider the proposed distribution while those are still choices. A supplier contract or declared payment may remove that flexibility. Don't assume a discretionary proposal stays discretionary after you've formally committed it.

Avoid counting the same future gain twice. The equipment saving shouldn't fund both the larger campaign and the owner's distribution unless the forecast supports both. Likewise, projected sales from the new campaign can't make the investment affordable before those sales are received unless another confirmed funding source covers the wait.

Repeat the test across the whole calendar when dates share an audience, suppliers or weather exposure. Several events can disappoint together. A reserve based on one weak show may be inadequate if the same problem affects the entire season. Describe the common dependency and decide how much of it you can afford to accept.

Judge an expansion by the full commitment

Before confirming the two smaller projects, the fictional company also considers moving its next event into a larger venue. This would use the same $12,000 currently proposed for equipment and promotion. The current format has 500 sellable places. The larger venue would provide 800 on an otherwise comparable, properly checked layout.

Assume the change adds $4,000 of venue cost, $5,000 of production and $3,000 of staffing. Together, the incremental fixed cost is $12,000. Those are all the additional fixed costs in this simplified comparison. The existing format's costs remain funded in the baseline, and any other real costs would need adding before a decision.

The venue asks for an initial $4,500 deposit. That payment might look affordable beside the $40,000 allocation, but it doesn't describe the expansion's full exposure. You need to know what the signed agreement commits you to pay, when cancellation charges increase and what can actually be reduced if sales are weak.

For the comparison, assume the whole extra $12,000 becomes unavoidable on signing. Paying $4,500 now therefore leaves another $7,500 committed for later. The company cannot approve only the deposit in its investment record while leaving the remaining cost out of the cash forecast.

Next, compare the extra cost with what the additional places can contribute. Keep our separate fictional assumption of $30 contribution per additional retained ticket after every cost caused by the sale. Assume the original 500 places sell in either venue, with their prices and contribution unchanged. No additional sponsor or other income is assumed.

There are 300 additional sellable places. Selling all of them produces $9,000 of additional contribution. Against $12,000 of extra fixed cost, the larger venue makes the event's result $3,000 worse than delivering the original format to its existing audience. Even a sellout of the extra capacity doesn't recover the difference under these assumptions.

Recovering $12,000 at $30 per extra ticket would require 400 additional retained sales. The new layout adds only 300 places. A more optimistic sales forecast can't solve that capacity limit. The company needs a different cost, price or income proposal before considering whether demand supports the move.

Suppose the venue later reduces its incremental hire cost by $3,000 with the same service and no new conditions. Total incremental fixed cost would fall to $9,000. A sellout of all 300 extra places would then just recover that amount. The proposal would still need evidence of demand and room for a weaker outcome before it could be an attractive use of the surplus.

That doesn't mean larger venues are inherently poor investments. A revised format might support a different ticket mix, sponsor offer or production arrangement. Each change needs its own costs and evidence. Don't count a possible premium price increase while keeping the old audience forecast unquestioned, or add sponsor income without the work required to deliver it.

This is where retaining profit gives you a choice. You can fund the smaller improvements, keep investigating the venue and negotiate from a position where you don't need to sign today. If the expanded event remains commercially weak, the money can stay available for a proposal that works. Having earned the surplus doesn't create a requirement to spend it on the next edition.

Treat owner distributions and financing as separate choices

The proposed $6,000 owner payment is an additional ownership return. Regular compensation for work is already included in our fictional profit calculation. You shouldn't have to disguise ordinary pay as an occasional reward from whatever remains after every improvement idea has been funded.

Before approving the distribution, confirm what the business is legally allowed to pay and what records are required. For a UK limited company, GOV.UK's guidance on taking money out says dividends cannot exceed available profits from current and previous financial years and require formal records. A bank balance alone doesn't establish the permitted amount.

That is a UK company example. Your structure, jurisdiction, tax position, existing agreements and ability to meet obligations need their own review. A percentage allocation is an internal planning choice. It doesn't authorize a dividend, drawing, loan repayment or any other transfer by itself.

If ownership is shared, agree who decides between retaining funds and distributing them. One owner might need income now while another wants to expand. Put the proposals, evidence and approval requirements into the same discussion. Don't allow the person with account access to settle the policy through a transfer.

Financing also deserves a separate comparison. You might retain cash and borrow for a useful long-lived asset, provided the actual terms and repayment forecast make sense. BDC's guidance on financing growth explains how spreading an investment's payments can help protect cash reserves. That benefit comes with repayment obligations and financing costs.

Compare the complete choices. Paying cash uses funds immediately. Borrowing preserves some initial cash but commits future payments and may involve security, guarantees or restrictions. Leaving the purchase until later preserves flexibility but delays any benefit. Obtain real terms before choosing between them.

Don't borrow merely to maintain an arbitrary reinvestment percentage or justify an owner payment the business can't otherwise support. The proposal needs to work on its own assumptions. If repayment depends on an unproven expansion succeeding immediately, make that dependency explicit before signing.

Adjust the decision to your event calendar

A business with one annual edition needs to fund a long period between settlements. Its allocation review should cover the months of planning, deposits and ordinary overhead before the next dependable income. Reinvesting in a larger show can increase that funding requirement even when the expected margin improves.

For a recurring series, look across all the dates. A shared piece of equipment may have a stronger case when several confirmed events can use it. A permanent hire may be harder to support if only a short peak period needs the extra capacity. Match the commitment to the work you can credibly expect.

For a first successful edition, keep the uncertainty visible. You have evidence that one offer worked in one set of circumstances. You may not yet know how much demand repeats, whether the venue remains available or how the audience responds to a different date. A smaller second test can answer those questions without committing the full first surplus.

For an established format, question whether repeating the same spending still produces a useful result. Last year's campaign might have worked because the event was new. Equipment might now need replacement. A sponsorship may carry more delivery work than it once did. Reinvestment needs a current reason, even when it has become routine.

Consider the capacity of the people running the business too. Adding a new city may create more founder work than the team can deliver well. Funding producer support for existing dates could be the stronger improvement. Compare the effect on the whole business, including the events that would receive less attention.

If you won't run another edition, the decision changes again. Keep enough to close obligations, settle taxes and support any remaining buyer or supplier issues. Don't invent a growth project simply because the last event made money. Establish the appropriate route for closing or continuing the business with your adviser.

Write an allocation record before authorizing payments

You need a record short enough to review and specific enough to explain each decision. Keep it with the settled accounts, the cash forecast and the supporting quotes. A project budget without the reason it was approved becomes difficult to challenge when its assumptions change.

Use these fields:

• Period and events covered, with the confirmed profit and its tax basis.

• Available cash calculation, including existing obligations and restrictions.

• Existing protected balance and any proposed reserve contribution.

• Each project, its owner, total cost and payment dates.

• The problem being addressed, evidence and smaller alternative considered.

• Expected additional contribution or cash saving, with assumptions and downside.

• Initial spending release, later approval conditions and cancellation terms.

• Proposed ownership payment, legal checks and required approvals.

• Amount left uncommitted and information needed for its next review.

• Review dates and changes that require an earlier decision.

For our fictional company, the record would show the $40,000 allocation and its four uses. The equipment project would name the $9,000 cost, $750 assumed saving per suitable use and twelve uses needed for simple recovery. The promotion project would record its $3,000 ceiling and initial $1,000 release.

Keep committed cost separate from money actually paid. If you sign the equipment order today and pay next month, the remaining bank balance hasn't made the purchase optional again. Likewise, a $3,000 approved ceiling with only $1,000 released leaves $2,000 subject to the later decision, unless you've already contracted for it.

Use current event records to inform each review. Loopyah's event financial view brings connected sales, refunds and fees together, lets you add event costs and separates cash from profit. It helps establish the event position. The reserve, distribution and investment approvals still belong in your wider business decision.

Choose an earlier review when a major receipt slips, a project quote increases or an event is cancelled. Record what changed and whether you can still alter the commitment. Keep the original approval so you can compare the decision with the information available at the time.

Review the result before setting next year's percentage

After the next season, compare what you approved with what happened. Did the equipment replace the expected hire? How many suitable uses actually occurred? Did the campaign produce additional contribution, or mainly move purchases into an earlier week? Which costs were missing from the proposal?

Separate a weak decision from an uncertain outcome. A well-supported test can fail, and a poorly supported purchase can get lucky. Review both the evidence used and the result. That helps you improve future allocations without pretending that every profitable outcome proves the original reasoning was sound.

Also review the money you kept available. Was the protected amount sufficient for the situations you planned for? Did uncommitted cash let you respond to a better opportunity? If the funds remained untouched, that doesn't automatically mean the reserve was excessive. Revisit the exposure it was intended to cover.

Then calculate the percentage for reporting if it's useful. Keep its definition consistent. In our example, 30% went into approved improvement projects, while the proposed owner distribution was 15%. Reporting only that the company retained 85% would conceal how much was protected, committed or still undecided.

Before you approve the next payment, write the amount, its purpose, the date and the evidence required for it to work. If you can't explain those details yet, leave that part of the surplus uncommitted and set a review date. You can make the investment when the decision is ready without spending the money simply because the event earned it.
