Understand your result
See what a show may actually earn after the costs that are easy to overlook. This calculator uses the inputs above to produce a planning estimate. It does not predict sales or guarantee that the modeled price will work for your buyers.
Calculation formula
Worked example
For 42 items at $28 each, sales are $1,176. With $9 in product costs per item, $185 in event expenses, and card fees of 2.9% plus $0.30 across 28 card transactions, estimated profit is $570.50.
Before you rely on the estimate
- Do not treat every item as a separate card transaction if customers often buy two or more items in one purchase.
- Include unsold inventory only when it is lost or damaged; reusable inventory is not automatically an expense of that event.
- Remember discounts, cash sales, sales taxes and refunds are not modeled separately in this simplified estimator.
Frequently asked questions
What counts as a booth expense?
The booth reservation, required electricity, permits and any event-only rental charges can belong in the event-cost inputs.
Should I include my time?
Yes, if you want profit after labor. Include making labor in your per-item cost and event staffing time under other event costs, avoiding double counting.
Is this take-home income?
No. The estimate excludes income tax and any unentered operating expenses; it is not a cash-flow or tax return calculation.
