Fundraising Event Budget Calculator
Model your event expenses against ticket, sponsorship, and auction revenue to estimate net income for your NYC fundraiser. Adjust every line and watch the estimate update instantly.
A fundraising event budget balances what you spend against what you raise. This calculator lets you enter your own assumptions for guest count, ticket price, sponsorships, and every major expense line, then shows an estimated gross revenue, total expenses, and net revenue in real time. It is a planning aid, not a forecast of what your event will raise — your actual results depend on your audience, cause, pricing, and execution.
Event Budget Calculator
Model your expenses against revenue to estimate net.
How to use this calculator
- Start with your realistic guest count and average ticket price — not your stretch goal.
- Enter sponsorship revenue you have a reasonable basis to expect, including confirmed and likely tiers.
- For auction and paddle-raise revenue, enter the net you expect after item costs.
- Model catering per guest as food plus beverage plus service charge combined.
- Keep a 10–15% contingency on expenses; first-year events should lean toward the higher end.
What the numbers mean
- Gross revenue is the total of ticket sales, sponsorships, and auction/paddle revenue.
- Total expenses include venue, catering, production, decor, marketing, staffing, and contingency.
- Net revenue is gross minus total expenses — the amount available for your mission.
- Cost per guest helps you judge whether your ticket price leaves room for net revenue.
- The net ratio (net ÷ gross) is a planning reference, not a guaranteed benchmark.
Frequently Asked Questions
Is the net revenue figure a guarantee?
No. It is an arithmetic projection of the assumptions you enter. Actual results depend on your audience, cause, ticket sales, auction performance, and execution. Use it as a planning aid, not a promise.
Should I include a contingency?
Yes. A 10–15% contingency on expenses protects against cost overruns. First-year or complex events should use the higher end of that range.
How do I estimate auction revenue?
Enter the net you expect after item procurement costs. If you are unsure, start conservatively — auction revenue is the most variable line in a fundraising budget.
Does this tool save my numbers?
No. The calculator runs entirely in your browser for the current session and does not store or transmit your inputs. Refreshing the page resets the values.
What ticket price should I enter?
Enter an average across all ticket tiers (individual, patron, VIP). If you sell mostly one tier, use that price. Price tickets at roughly 2–3x your per-guest cost to leave room for net revenue.
