eBay fee and profit calculator · US

Estimate eBay fees, contribution profit and a target selling price for US domestic one-item orders in most categories without a Store.

Buyer sales tax is included when calculating the relevant payment or final-value fee base, but excluded from your revenue. The tax percentage is your scenario input, not a location-based tax determination. Postage charged to the buyer is revenue; postage you pay is a separate cost. The result is contribution profit before unallocated overhead and income tax.
