How many sales
cover your craft fair costs?

A booth fee is only part of the day. Before choosing an event, separate what you spend to attend from what each sale leaves behind.

1. Add the costs of attending

Start with expenses you expect regardless of sales: the booth fee, travel, parking, and any extra equipment hired for that event. In this example, a $75 booth and $25 of other event costs total $100.

If you already own your table and tent, you may still want to allocate a portion of their cost over future events. Be consistent across events so comparisons stay useful. Don’t count an expense in two places.

2. Find what an average sale contributes

Suppose an item sells for $25, excluding sales tax. Materials and packaging cost $8. An illustrative payment fee is 3% plus an estimated $0.15 per item sold. These are example inputs, not a quote from a payment processor.

If the processor charges per transaction, spread that fee across the typical number of items in each transaction. Use your actual fee schedule and mix of card and cash sales. If you sell several products, use a realistic sales-weighted average or calculate them separately.

3. Divide, then round up

Divide the $100 fixed costs by the $16.10 contribution. The result is about 6.21 items. Because you can’t sell part of an item, round up to 7 items. Seven sales cover the entered event costs. They do not yet compensate you for working the day.

4. Give your time a separate target

Imagine eight total hours including prep, travel, setup, selling, and packing. If you want $20 for each hour, add $160 to the target. Now you need to cover $260. Divide that by $16.10 and round up: 17 items.

This is a personal planning target. If labor is already included in your item cost, adjust the calculation so you don’t count it again.

5. Ask whether the target is plausible

The calculator can’t tell you whether you will sell 17 items. Look at your own past events, the event audience, product fit, table location, and what the organizer can explain about attendance. Attendance and sales are different things.

Use the number to ask better questions, rather than as a prediction. A higher-cost event may still make sense for your goals, but make those goals explicit.

After the event

Record revenue, units sold, actual costs, and hours. Note what customers asked, which products moved, and what you would change. Estimated surplus is not take-home profit: taxes, overhead, unsold stock, and missing expenses can change the picture.

The next useful step is to compare your plan with your own results, not with someone else’s highlight reel.
