Did you know that a school fundraiser can sell every ticket and still collect less money than its sales chart promises? The total written on ticket orders is not necessarily the amount that reaches the school club’s account. An online payment processor may deduct a percentage, a fixed charge for each payment, or both.
Gross receipts are the total payments for sales or donations before deductions; a net payout is what arrives after relevant payment fees are removed. To find money actually available for the project, subtract any further event costs as well. Record who pays each fee and whether the fee applies per transaction or per item. Do not confuse a ticket price, a gross order total, a platform payout and the event’s final surplus.
Why the number on the fundraising poster is not the whole story
A poster saying ‘We raised $800’ may accurately describe gross receipts. It does not automatically mean the organisers have $800 to spend. Some payment services deduct charges from the proceeds before transferring the remainder; others show an optional or required extra charge to supporters. The arrangement differs across services and payment methods.
Before doing mathematics, read the actual agreement or school-approved payment instructions. One provider might have a percentage charge per transaction, another a fixed fee per checkout, and another might pass costs to the supporter. For a concrete example of how payment arrangements can vary, see a provider’s published fundraising payment terms; those terms are not the assumed fees in our classroom problem and should not be applied automatically to another platform.
Diagnose the problem before reaching for a calculator
- Does the amount refer to ticket sales, donation promises, money received, or money finally settled?
- Which transactions were cash and which were processed electronically?
- Does the percentage apply to the gross amount charged, and is the fixed charge per checkout or per item?
- Who actually pays the fee: the supporter, the organising group, or another party?
- What additional event costs, such as materials or approved venue charges, must be paid?
- Are refunds, failed payments and any other deductions recorded separately?
A learner who starts subtracting percentages without finding the fee basis may produce a neat but incorrect answer. The educational goal is not a clever shortcut; it is a transparent reconciliation that a second pupil can check.
Worked example: a ticket sale total is not the final surplus
All amounts and fee rates below are illustrative, not a statement about any actual school’s provider. A student club sells 80 tickets at $10 each. Fifty tickets are paid for in 50 separate online transactions; the other 30 are paid for in cash. Gross receipts are 80 × $10 = $800. Online receipts total 50 × $10 = $500; cash receipts are 30 × $10 = $300. Together they still equal $800.
Assume the club, rather than supporters, bears an online processing fee of 3% of each online payment plus $0.30 per online transaction. For one $10 online payment, the fee is 0.03 × $10 + $0.30 = $0.30 + $0.30 = $0.60. Across 50 identical transactions, processing fees are 50 × $0.60 = $30. There is no online processing fee on the 30 cash tickets under this invented arrangement.
The amount after online processing is $800 − $30 = $770. Suppose the club also spends $210 on supplies and $60 on an approved event space. Total other costs = $210 + $60 = $270. The resulting project surplus is $770 − $270 = $500. Check the same result another way: $800 gross − $30 processing − $210 supplies − $60 venue = $500. Both methods reconcile.
The difference between the headline total and spendable surplus is $300. That is not proof that money vanished: $30 went to assumed processing charges and $270 to the stated event costs. Each deduction should correspond to a genuine receipt, documented fee or approved expense. If the club’s declared target is $500 after all these costs, it reaches that illustrative target exactly; if the target is $800 of spendable funds, it does not.
The hidden trap: a fixed fee is usually counted by transactions
In this example, charging only one fixed $0.30 fee on the total $500 of online ticket sales would understate the fixed charges. Fifty separate checkouts produce 50 fixed charges, totalling $15, alongside $15 in percentage charges. Conversely, charging the fixed fee per ticket would be wrong if a platform actually charges once per combined checkout. Number of tickets and number of payments are not necessarily the same quantity.
If a supporter pays processing costs on top of the ticket price, a different budget applies: the club could retain the full $800 gross ticket proceeds and, after the same $270 event costs, have $530. But confirm whether the extra fee is genuinely borne by the supporter and whether any other deductions exist. Never substitute that more favourable model without evidence.
A clearer event worksheet
- Line A — gross confirmed ticket or donation receipts, separated by payment type.
- Line B — percentage processing charges actually borne by the group.
- Line C — fixed checkout charges, using the number of transactions.
- Line D — refunds, adjustments, or other confirmed deductions, if any.
- Line E — payout after payment deductions: A − B − C − D.
- Line F — separately paid event costs such as supplies and approved facilities.
- Line G — final event surplus: E − F. Keep an evidence note for each line.
The same worksheet works as a budget forecast before the event and as a reconciliation afterward, but label the forecast as an estimate. Real order counts, cash receipts, fee terms and refunds can change. A useful project displays forecast and actual in separate columns instead of quietly rewriting the original budget.
Progressive practice: a new set of numbers
Guided practice
Twenty supporters each pay $15 online in 20 separate checkouts. Assume a fee of 2% plus $0.20 per checkout, borne by the club. One checkout costs 0.02 × $15 + $0.20 = $0.50. All fees total 20 × $0.50 = $10. Gross receipts are 20 × $15 = $300. After the fees and $70 of other event costs, the surplus is $300 − $10 − $70 = $220. Explain what each subtraction represents.
Partly guided practice
Now assume those same 20 tickets are sold in 10 checkouts, two tickets per checkout, with the same percentage and fixed fee schedule. Total percentage charges remain 2% of $300 = $6. The fixed portion becomes 10 × $0.20 = $2, for total fees of $8. The new surplus would be $300 − $8 − $70 = $222. Only the fixed-charge count changed.
Independent challenge
Design a small project with 40 tickets, two payment methods and two expense lines. Choose and label clearly hypothetical fee terms. Calculate gross receipts, provider deductions, payout and final surplus, then invent a common error and show how an independent reader would detect it. If your numbers do not reconcile, find the mismatch before presenting the result.
Practical next steps for families and school teams
- Student treasurer: Keep a simple ledger and transaction count; do not publish personal donor details in a public class report.
- Teacher adviser: Approve payment methods and cash handling in line with school rules; supervise collection and reconciliation.
- Parent: Ask whether the fundraising target is gross proceeds or money left for the project, and whether the fee assumptions are documented.
- Project team: Communicate final figures with the appropriate labels and keep receipts, refunds and authorised expenditure traceable.
What progress looks like
The first success is using the words gross, payout and surplus accurately. The next is calculating the fixed charge the correct number of times. Stronger understanding shows when a pupil can model two different payment arrangements, identify a missing refund or cost, and explain a difference between forecast and actual without inventing a reason. Those are transferable financial-literacy skills.
Frequently asked questions
Is the net payout always the same as fundraising profit?
No. The net payout from a payment processor usually accounts for the processor’s deductions. A fundraiser may still need to pay materials, transport, venue charges or other approved costs. The money remaining after all relevant costs is the event surplus in this example.
Is a 3% fee the same as taking 3 dollars?
No. Three percent means three parts per hundred of the amount to which it applies. On $10 it is $0.30; on $100 it is $3. Check the rate, base amount and any additional fixed charge before calculating.
What if a payment fails or is refunded?
Do not count an uncollected promise as confirmed cash. Record refunds and fee reversals, if applicable, according to the actual account statement. Payment services differ in how they handle refunds, so refer to the real statements and authorised school process.
The core aim: make each number explainable
A budget should tell a story anyone can independently check, not merely present a large appealing number.
