How this calculator works
This is the calculator you use afterwards. Enter what an event actually produced and it scores the return, so you can compare a busy market that cost a fortune against a quiet one down the road.
The figure that changes decisions is earnings per total hour — travel, setup, teardown and prep included. A show that pays $40 an hour while the doors are open often pays $15 once the whole weekend is counted.
The formula
- Gross profit = revenue − cost of goods − card fees
- Net profit = gross profit − booth − travel − lodging − food − staffing − other
- ROI = net profit ÷ (event costs + cost of goods sold)
- Earnings per total hour = net profit ÷ (show + setup + travel + prep hours)
What to watch for
- Earnings per total hour is the figure that makes events comparable. Show hours flatter every event equally, so ranking by them tells you nothing useful.
- Prep time is real and almost always forgotten: pricing stock, packing, checking the float, loading the car. Six hours before a two-day fair is normal.
- ROI is measured against everything you put in, including the stock you sold. A high ROI on a tiny event can still be worth less in cash than a modest ROI on a large one — read both figures.
- Score every event the same way and a year of data will tell you which ones to reapply to. Memory is unreliable, and the busiest-feeling event is frequently not the most profitable.
Common mistakes
- Judging an event by revenue, which ignores both the booth fee and the cost of the stock.
- Counting only show hours and concluding an out-of-town fair paid well.
- Forgetting prep and packing time in the days beforehand.
- Reapplying to an event because it felt busy rather than because it scored well.
Frequently asked questions
How do I know if a craft fair was worth it?
Compare net profit per total hour against what those hours would have earned making and selling stock another way. An event that returns $18 an hour once travel, setup and prep are counted is worse than a quiet day in the workshop for most established makers — even if the event felt like a success.
What is a good ROI for a craft fair?
There is no universal figure, because it depends what the alternative was. What matters is the comparison across your own events, scored the same way. Run a year of shows through this and the pattern is usually obvious — and often surprising.
Should I count my own time as a cost?
Not as a cash cost, because paying yourself does not change whether the event made money. Instead read the earnings-per-total-hour figure and compare it against your normal hourly return. That answers the real question: was this weekend a better use of the time than the alternative?
Why does my per-hour figure drop so much when I include travel?
Because travel, setup, teardown and prep frequently equal or exceed the show hours themselves. A fourteen-hour weekend fair can easily carry another fourteen hours around it, which halves the effective rate. That is exactly why out-of-town events need to earn substantially more to be worth the same.
