Dance-a-Thon Fundraising Calculator

What each dance-a-thon fundraising calculator input means

The inputs follow the order money moves: people dance, some ask donors, donors promise, most promises get paid, and fees and costs come out. Every starting value is an illustration; replace it with your own number.

Input	What it means	How to estimate it
Eligible participants	Everyone you invite to dance: enrolled students, members, or families on your list.	Enrollment or your invite list.
Participation rate	Share of eligible people who take part.	Last year's sign-ins ÷ invited.
Share of dancers who fundraise	Dancers who bring in at least one donor.	Count pledge sheets or donation pages that brought in money, ÷ dancers.
Donors per fundraising dancer	Average number of people who give to each dancer who fundraises.	Total donors ÷ fundraising dancers from last year's tally.
Average gift per donor	The expected total from one donor. For per-song or per-hour pledges, enter what the pledge adds up to, not the rate.	Run your rate and planned dancing time through the per-song and per-hour pledge calculator first.
Pledge collection rate	Share of promised money that is actually paid.	Collected ÷ promised from last year. Per-song and per-hour pledges are paid after the event, so some never arrive.
Sponsorships	Total sponsor money you expect.	The expected revenue from the sponsorship calculator.
Registration fee and share paying	An entry fee, and the share of dancers who pay it.	Leave the fee at $0 if entry is free.
Other revenue	Concessions, raffle, glow-item sales.	Count only money you are fairly sure of.
Online share, card rate, fixed fee	How much money comes in by card, and what your payment provider charges. The fixed fee starts at $0.30 and is charged only on gifts actually paid online.	Your provider's published rate. Set the fixed fee to $0 if there is none.
Event expenses	Everything the event costs.	The total from the dance-a-thon budget builder.
Goal (optional)	The net proceeds you want after fees and expenses.	Your board's or PTA's target.

If you are still deciding between flat gifts and per-song or per-hour pledges, the guide to dance-a-thon pledge models compares them before you settle on an average gift.

How the math works

1. Dancers = eligible × participation rate, rounded to whole people.
2. Fundraising dancers = dancers × share who fundraise, rounded.
3. Donors = fundraising dancers × donors per fundraiser, rounded.
4. Gross pledged = donors × average gift. Collected = gross pledged × collection rate. The difference is shown as "Not collected".
5. Registration = (dancers × share paying, rounded) × fee.
6. Total collected revenue = collected donations + sponsorships + registration + other revenue.
7. Processing = (collected donations + registration) × online share × card rate, plus online gifts × fixed fee, where online gifts = donors × collection rate × online share. Pledges that are never paid carry no fee.
8. Net proceeds = total collected revenue − processing − event expenses.

Illustrative: with the tool's starting values, 400 eligible × 90% = 360 dancers. 360 × 60% = 216 fundraise. 216 × 5 = 1,080 donors. 1,080 × $30 = $32,400 pledged, and 90% of that, $29,160, is collected ($3,240 is not). Add $1,500 in sponsorships and $500 of other revenue and total collected revenue is $31,160. Card fees are $29,160 × 70% × 3% = $612.36, plus the fixed fee on gifts actually paid online: 1,080 donors × 90% collected × 70% online = 680.4 gifts × $0.30 = $204.12. Processing totals $816.48. Net = $31,160 − $816.48 − $2,000 expenses = $28,343.52, or $78.73 per dancer, keeping 91% of collected revenue. Open "Explain the math" under the results to see the same lines with your own numbers.

Conservative, Base and Optimistic scenarios

Base is what you typed in. Conservative and Optimistic start from Base × 80% and Base × 120% for the five drivers: participation rate, share who fundraise, donors per fundraiser, average gift and collection rate. Rates are capped at 100%. Those multipliers are planning assumptions, not research findings. Change either multiplier and press "Refill both from Base", or type over any single value. Sponsorships, registration, other revenue and expenses stay the same in all three columns.

Notice how far apart the columns land. The five drivers multiply together, so 80% of each leaves roughly a third of the Base donations, not 80% of them. In the example, Conservative nets $9,255 and Optimistic $60,539 against a Base of $28,344. A better approach than a flat multiplier is to set each side value to something you can defend: participation in a school-day gym session may barely move, while average gift and collection rate can swing a lot.

Gross pledged, collected and net

• Gross pledged is promises. For per-song or per-hour pledges, it is what donors would owe if dancers dance the planned time.
• Total collected revenue is money that actually arrives from donations, sponsors, registration and other sales.
• Net proceeds is what is left for your cause after card fees and event costs. This is the honest number to report afterward.

"Net per dancer" divides net by everyone who danced, not only fundraisers. "Share of collected revenue kept" is net ÷ total collected revenue.

Using the goal solver

Enter a goal and the calculator compares it with Base net. If Base falls short, it gives three separate levers, any one of which closes the gap on its own: more fundraising dancers, a higher average gift, or more donors per fundraiser. Each donor is worth average gift × collection rate × (1 − online share × card rate) − collection rate × online share × fixed fee, and donations have to cover the goal minus what sponsors, registration and other revenue bring in after expenses.

Illustrative: with the starting values and a $35,000 goal, sponsorships plus other revenue exactly cover the $2,000 of expenses, so donations must net the full $35,000. Each donor nets $30 × 90% × (1 − 70% × 3%) − 90% × 70% × $0.30 = $26.24, so you need about 1,334 donors. That means about 267 fundraising dancers at 5 donors each, or an average gift of about $36.99, or about 6.2 donors per fundraiser. The line underneath lists which scenarios reach the goal; here only Optimistic does. If the fundraisers needed exceed your dancers, the tool says that lever cannot get there alone.

Estimating inputs from last year's dance-a-thon

Your own history beats any outside number. Pull four records: the sign-in list (dancers), the pledge tally or donation export (fundraisers, donors and promised totals), the deposit record (collected), and the final expense report. From those you can compute every Base driver directly. If last year's event was a different format, carry over what is about people (participation, donors per fundraiser) and rework what is about time: a 90-minute evening dance and a set of 30-minute class blocks produce very different per-song totals.

For a first event, plan on the Conservative column and treat Base as a stretch. To sanity-check the scale, see what documented dance-a-thons have raised. Those come from published results, which lean toward successful events, so they are not a forecast for yours.

What the calculator can't know

• Whether dancers dance as long as planned. Per-song and per-hour pledges shrink when kids sit out; adjust the average gift.
• When the money arrives. Collection runs for weeks after the event, and the projection has no calendar.
• Card fees on sponsorships and other revenue. The tool counts those without fees; if yours are paid by card, add the fee to event expenses.
• Employer matches, in-kind gifts, refunds, or one large gift.
• Whether your expense total is complete. It is only as good as the budget behind it.

Use "Copy summary" or "Print" to share the three columns with your committee, and the dance-a-thon fundraising guide for the plan around the numbers.
