A corporate event budget template should show the approved ceiling, each cost category, evidence behind the figures, committed spend and the remaining forecast. Add a per-person total and explain what could still change. The template below is a spreadsheet layout you can copy into Excel or Google Sheets; its example figures are invented to demonstrate the arithmetic, not UK supplier rates.
If you need market benchmarks rather than a working sheet, use the separate UK corporate event cost guide.
Copy this budget structure
Use one row per supplier or cost item. Keep the summary above the detail.
| Column | Meaning |
|---|---|
| Category and item | Venue, catering, AV, travel, hotels, transfers or staffing |
| Owner | Person responsible for validating the line |
| Evidence and expiry | Quote reference, estimate source and last valid date |
| Original allowance | The approved baseline for that line |
| Committed total | Contracted amount, including any deposit already paid |
| Uncommitted forecast | Additional expected cost that has not been committed |
| Forecast final cost | Committed total plus uncommitted forecast |
| Paid to date | Cash already paid; part of the commitment, not an extra cost |
| Currency and tax basis | Currency, whether tax is included, and unresolved treatment |
| Change note | Why the forecast differs from the allowance |
Ask finance how it wants tax and currencies represented. Do not add a universal tax percentage to every supplier line: the supplier's quoted treatment and the company's reporting basis need checking.
Use formulas that avoid double counting
With the columns above, use these definitions consistently:
- Forecast final cost: committed total + uncommitted forecast.
- Unpaid commitment: committed total − paid to date.
- Variance: forecast final cost − original allowance. A positive figure means an overrun in this sheet.
- Remaining headroom: approved overall ceiling − total forecast final cost.
- Cost per attendee: total forecast final cost ÷ expected attendees.
Do not add paid-to-date to committed total. A deposit is a payment against a commitment, not another purchase. Also state whether your forecast includes contingency; adding the same reserve twice makes the budget misleading.
Worked example: a venue line
Suppose the venue allowance is £6,000. The team has contracted £5,000, paid a £1,000 deposit and expects £500 of additional room support that is not yet contracted.
The forecast is £5,500. The unpaid commitment is £4,000. The line is £500 below its original allowance. Those are three different measures: final cost, cash still due on the contract and variance.
For an illustrative event forecast of £18,000 and 60 expected attendees, the per-attendee figure is £300. If only 50 attend and the same total is spent, the actual figure becomes £360. Keep expected and actual attendance separate so the denominator is clear.
Keep cash flow beside the budget
Add a second tab with supplier, amount due, due date, approval owner and payment status. An event can remain within budget and still have several deposits due in the same week. Finance needs that timing to plan payments.
Link each payment milestone to its supplier evidence. If a quote expires before approval, recheck it rather than describing the old price as available. The procurement checklist explains the handover from quote to commitment.
Send finance a decision, not a spreadsheet puzzle
Your approval summary should state the proposed option, forecast total, per-person figure, largest uncertainties and deadline for a decision. Include the alternative you considered and any change from the previous version.
Getting an event budget approved covers the review conversation. After delivery, use the post-event report template to reconcile the forecast against the final outcome.
Comtev brings estimates and supplier quotes into an event budget and lets you freeze a versioned, shareable cost proposal. See the budget workflow if maintaining quote references and approval versions manually is becoming the larger job.
FAQs
What should a corporate event budget include?
Include venue, catering, AV, staffing, activities, attendee travel, hotels and transfers where relevant. Show evidence, commitments, uncommitted forecast, payments, contingency treatment and the approved ceiling.
Should a deposit be added to the total event cost?
Only as part of the supplier's contracted total. Track the deposit in paid-to-date and cash flow; adding it again to the commitment would count the same cost twice.
