FREE CALCULATOR · EVENT ROI
Craft fair profit and event ROI calculator
Estimate an internal craft-market result from entered revenue, COGS, booth, travel, lodging and payment fees, then compare event ROI.
01
How event profit and ROI differ
- The displayed result subtracts entered COGS, booth, travel, lodging and payment fees from entered revenue.
- Sell-through compares entered units sold with entered units brought.
- The displayed event ROI divides the internal result by direct operating cost, not by revenue.
- These figures describe the selected formula and do not recommend whether to book a market.
CHECK
Before interpreting the result
Enter amounts from your own records and check the unit used by each field. The calculator does not validate sales, costs, hours, inventory, payments, fees or percentages, and it does not retrieve data from external sources.
Change one input at a time and compare several scenarios. This helps separate the mathematical effect of each assumption without presenting the output as a confirmed price, margin, profit, budget or available amount.
Use the output to structure an initial comparison. Before making a tax, legal, accounting, financial or commercial decision, check current information and your specific circumstances with an official source or a suitably qualified professional.
FAQ
Frequently asked questions
How does this calculator treat COGS in event ROI?
It subtracts entered COGS from the internal result but uses entered direct event operating costs as the ROI denominator. Other methods may differ.
What counts as sell-through?
Items sold divided by items brought for the event. Keep bundles and multi-item sales consistent in both counts.
Does a high ROI select a market?
No. The tool displays entered profit, ROI and sell-through separately and does not determine market suitability.
The complete workbook connects product inventory, event costs, sale-level records, COGS, fees, completed-event ROI and a portfolio dashboard.
