How the calculation works
Fixed event costs are divided by contribution margin per sale. Contribution equals the selling price less unit product cost and payment-processing fee. Expected profit or loss then applies the entered expected unit sales.
Input guide and example
Separate travel, hotel, booth, staff, samples, and materials so you can see what the event must earn back. Conservative and strong cases simply scale your expected sales; they are not forecasts.
Assumptions and limits
Use one currency and enter the definitions, rates, and costs from your actual agreement, quote, or sales plan. This is a scenario calculator, not legal, tax, accounting, or commercial advice.
