Free marketplace profit tool
Compare reseller fees and profit across marketplaces.
Use a marketplace preset as a starting point, then replace every fee with the current numbers that apply to your account. Compare net profit, margin, and ROI before you decide where to list an item.
Marketplace presets are editable starting assumptions, not official fee quotes. Verify the current fees for your category, account, region, shipping setup, and promotions before making a sourcing or pricing decision.

Why editable assumptions matter
Marketplace fees are not one permanent percentage. They can vary by category, account, region, shipping, promotions, payment rules, and policy changes. This calculator is designed to be updated by the seller rather than silently relying on stale fee tables.
