Fair Margin — Craft Fair Profit & Pricing Planner

Know your profit before you book the booth.

Fair Margin helps handmade sellers calculate true product costs, compare fee-aware prices, plan craft-fair expenses and break-even sales, forecast event profit, then record actual results and compare forecast versus actual.

Included: batch costing, editable date-stamped fee profiles, event inventory and expense forecasts, break-even estimates, forecast-versus-actual reconciliation, ROI, hourly profit, searchable history, comparisons, CSV reports, JSON backup/restore, and a built-in How to Use guide.

Offline-first, private, and subscription-free. No account is required. Currency is displayed in USD. Fair Margin is a planning tool; results depend on the information entered and are not guaranteed. It is not financial or tax advice.
