The fee rates are pulled from each marketplace's own published fee pages and sit in the advanced section below, editable in case they change after this was written.

Estimate only. Excludes sales tax (collected and remitted separately by the marketplace) and fee variants this calculator doesn't model: TCGplayer Direct, Sync/Crystal Commerce accounts, international transaction rates, and PayPal payout fees. TCGplayer's 2.5% transaction fee applies to the order total including sales tax, so on sales where tax is collected the real fee runs slightly higher than shown here.
