Thrift profit calculator

How to use this calculator

Enter your expected resale, what you would pay in-store, marketplace fee percent, and outbound shipping. The calculator shows estimated fees and projected net profit.

Marketplace fees matter

eBay, Poshmark, and Mercari take different cuts. Always model fees on the price you expect to actually receive, not a best-case listing price.

Next step: scan the item

Calculators are a starting point. Scan the item in Thriftox to validate comps, spot risk flags, and save profit inputs to inventory.

Fast answer

Projected net ≈ expected sale price − marketplace fees − store cost − outbound shipping − supplies. Use a conservative sale price. This is educational planning math, not a payout forecast.

Worked example

Illustrative planning math: thrift sweater with a clear brand tag at $6 store cost. Expected eBay resale $22–$35. After about 13.25% fees and $6 shipping, projected net is roughly $7–$18 before supplies. Not a guarantee.

Workflow

• Enter the low end of sold comps, not the best-case listing.
• Use the fee percent for the marketplace you will actually use.
• If net is thin, skip — then scan the next rack find.
