Why these calculators exist
Built from official fee pages
Every rate comes from the marketplaces’ own US seller fee documentation — not guesses, not outdated blog posts. See our methodology and fee sources.
Itemized, not just a total
Each tool shows every fee line — final value, transaction, processing, per-order — so you can see exactly where your money goes.
Kept current
Fee schedules change. We re-check every platform and log changes in the fee change tracker so your math stays right.
