About this calculator

Field trips get budgeted casually until the bus company invoice and admission tickets come due. This calculator totals transportation, admission, substitute chaperone pay, and a contingency buffer, then divides by student count to set the per-student fee, flagging when the fee exceeds a threshold that would require a fee waiver pool for lower-income families.

FormulaTotal cost = transport + admission×students + chaperone pay + contingency. Per-student fee = total cost ÷ students.

FAQ

Why add a contingency buffer?

Attendance counts shift between the deposit date and trip day, and venues sometimes add last-minute fees. An 8-10% buffer absorbs this without needing to go back to families for more money.

How should schools handle students who can't pay?

Build a small fee waiver pool funded by a modest overage built into every other family's fee, or by PTA fundraising, so no student is excluded from a required curricular trip over cost.

Does chaperone pay apply to volunteer parents?

No — this line is for paid staff coverage such as a substitute teacher covering the trip-leading teacher's other classes, not for parent volunteers who typically aren't paid.

What's a reasonable per-student fee ceiling?

Many districts try to keep single-day trip fees under $20-$25 per student to avoid effectively pricing out lower-income families from a curricular activity.

Accuracy and limitations

Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
