For craft fairs and vendor markets
Know if the booth fee can pay back before you book.
Market Math turns your booth fee, traffic estimate, product costs, card fees, conversion rate, and inventory into a clear break-even target and a GO, BORDERLINE, or PASS decision.

Event assumptions
Your forecast
Estimate only. The full workbook adds product-level inventory capacity, target profit, safety margin, actual logs, and a forecast-versus-actual scorecard.
The missing decision
Most vendor planners begin after you already paid.
Market Math begins with the booking decision, then carries the same assumptions into inventory, preparation, sales, expenses, and the post-event review.
Price the full event
Include booth, travel, parking, lodging, permits, paid help, display allocation, processor fees, and product cost.
Cap sales by inventory
The workbook uses the lower of forecast demand and the sales value of everything you can actually bring.
Learn from the result
Compare forecast with actual sales, orders, expenses, product cost, profit, and profit per working hour.

Questions
Plain answers.
Does this guarantee an event will be profitable?
No. It creates a planning estimate from the assumptions you enter. Attendance, weather, buyer behavior, organizer execution, product-market fit, and other conditions can change the result.
Where does the break-even formula come from?
The method follows the U.S. Small Business Administration's break-even framework: fixed costs divided by contribution margin for break-even sales, or fixed costs divided by price less variable cost for units.
What software do I need?
The XLSX workbook is designed for Microsoft Excel and compatible spreadsheet applications. It contains no macros or external data connections.
Can I reuse it?
Yes. One buyer or one small business may make copies for its own events. The workbook may not be resold, redistributed, or published as a template.
Is this accounting or tax advice?
No. It is a planning tool. Use your own records and qualified advisers for accounting, tax, legal, insurance, and event-contract decisions.
