Event Budget Versus Actual Review

Check the numbers after an event.

Added October 15, 2026. Written with AI assistance and checked for clarity and placeholders; not reviewed by a lawyer, accountant, clinician or other professional. How these prompts are made

The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.

[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it (what [VERIFY] means).

Review an event budget against actual costs and income. Budget lines, actual amounts and notes: [EVENT_FINANCIALS]. Attendance and ticket sales: [ATTENDANCE_SALES]. Sponsorship promised and received: [SPONSORSHIP].

Calculate variances, identify the three largest, separate controllable from uncontrollable causes, compute cost per attendee, and check that promised income was received. Show the arithmetic.

Return a table with Line, Budget, Actual, Variance and Cause, three lessons for the next event, and a template for a short post-event financial summary.

Also suggest a template for a one-page financial report to the organising committee, and a rule for setting next year's budget from this year's actuals.

Label every assumption, keep forecasts as ranges rather than predictions, and tag legal, tax and reporting requirements [VERIFY] for [JURISDICTION] before I rely on them.

Also note which variances were caused by late decisions and which by supplier changes, so that next time the right person is asked earlier.

End with a one-page action plan under four headings: stop, start, change and keep, each with no more than three items.

Fill in before use

Optional: type your details and the prompt above updates. Nothing is saved or sent.

Replace each bracketed placeholder with your own details, then paste into Any AI or another assistant.

Variance table (invented, 120 attendees)
Venue: budget 3,000, actual 3,000. Catering: 4,800 vs 5,640 (+840; 24 more meals and a late dietary change). AV: 900 vs 1,250 (+350; extra microphones). Marketing: 600 vs 450 (-150). Total costs: 9,300 budget vs 10,340 actual (+1,040).
Income: tickets 120 x 90 = 10,800 budget; actual 112 x 90 = 10,080; sponsor 2,000 promised, 1,500 received.
Net: budget +3,500 (10,800 + 2,000 - 9,300); actual +1,240 (10,080 + 1,500 - 10,340).
Cost per attendee actual: 10,340 / 112 = 92.3.
Lessons: confirm numbers 7 days out; get sponsor payment before the event; agree AV list.
