FAIR CALCS - RESALE CALCULATOR
Estimate what a Mercari sale leaves after fees and costs.
Use the reviewed Mercari starting profile, then add item cost, shipping, packaging, and other expenses to see estimated net profit.
Starting fee assumption
The reviewed U.S. profile starts with a 10% seller fee on item price and buyer-paid shipping and no separate seller payment-processing fee. Marketplace policies can change.
Compare before cross-listing
The comparison section applies the same item and cost assumptions to every built-in marketplace. It compares fees only, not demand or likely sale price.
Marketplace fees change and vary. Results are estimates, not tax or accounting advice.
