- Dead-weight inventory
- Per-item production plan
- 100% private (browser-only)

Actual tool output — 3 events, 353 units sold.
Booth Fee Evaluator
Is this show worth applying to?

- Break-even transactions
- True hourly take-home
- Drive + prep time factored in
Show Profit Calculator
Did you actually make money?
Revenue, expenses, and cost of goods sold in. Your real craft show margin out — including the stuff that adds up quietly.
- Gross vs. true profit margin
- Overhead you usually forget
- Per-product margin breakdown
Which tool should I use?
Still deciding on a show? Start with the Booth Fee Evaluator. It factors in booth fee, drive distance, and prep time so you can tell if an event is worth applying to before the deposit clears. Pair it with our guides on finding craft fairs near you and pricing your first show.
Just finished an event? Run the numbers through the Show Profit Calculator to see what you actually kept after overhead and cost of goods. It's the same math we walk through in how to track craft fair performance.
Using Square at the booth? Export an Item Sales Summary CSV and drop it into Square Insights to find your real bestsellers, consistent dead weight, and how much to make for the next market. The full workflow is in using Square sales data to plan your next market.
One tool per question. One app between the shows.
The tools answer a single question in a single moment. MyEventPrep remembers what happened at every event — so your next prep sheet starts from what actually sold, not from a blank page.
