Trading card seller calculators
Before buying a card, work out your offer ceiling. Before listing it, estimate what you keep after fees and shipping. These tools use your numbers and show their assumptions.

Which number should you use?
Net proceeds are revenue after marketplace fees. Subtract postage and supplies to find what remains for your purchase cost and profit. Maximum buy price reserves your target profit from that remaining amount before you make an offer.
Enter a realistic resale price for the same printing and condition. An asking price is not a guaranteed sale. These calculators do not predict prices or include your time, income tax, returns or unsold inventory.
For the fee bases and a worked example, read TCGplayer fees explained. Explore more seller guides.
