Event Break-Even Calculator
How many tickets must you sell before your fundraiser stops costing money? Enter your costs and ticket price and see the break-even point — and how sponsorships move it.
Costs & pricing
Fixed = venue, A/V, décor, marketing — the same at any headcount. Variable = catering, favors, per-person fees.
Average auction/appeal/raffle spend per person, if you can estimate it from past events.
Break-even point
The break-even formula
Break-even attendance = (fixed costs − sponsorships) ÷ (ticket price − variable cost per person). The bottom of that fraction is your margin per ticket — what each attendee actually contributes after their dinner is paid for. If your ticket price barely clears the catering cost, no amount of attendance will rescue the event; that’s the first thing to check.
Sponsorships shift the whole curve: every sponsor dollar reduces the fixed costs tickets must absorb. This is why experienced galas sell sponsorships first and open ticket sales second — often the event has already broken even before the first ticket sells.
Reading your numbers
- Break-even above 60–70% of capacity is risky. A rainy night or a competing event can push you into a loss. Aim to break even at half the room or better.
- Negative or tiny margin per ticket? Raise the price, cut the per-plate cost, or add a sponsored element (a bar sponsor turns your biggest variable cost into someone’s marketing budget).
- Model the whole event, not just tickets. Use the event budget calculator for the full picture including auctions and appeals, and the ROI calculator to judge the result.
Planning estimate only — confirm quotes with vendors, and remember RSVPs are not attendance: 5–10% of paid guests typically no-show (their catering may still be billed).
