Use this calculator before setting a Amazon FBM price in United States

Sellers often lose margin through small costs that are easy to miss: payment fees, marketplace commission, shipping gaps, advertising spend, returns, packaging, and tax reserves. This page gives a quick planning model in USD so you can compare products before listing or scaling ads.

SEO-ready pricing workflow

  1. Enter a realistic sale price and landed product cost.
  2. Add shipping cost, ad cost per order, and a return reserve.
  3. Check whether net margin stays positive after fees and tax reserve.
  4. Compare the same product across related marketplaces and countries.

Profit planning example

FBM orders often look stronger than FBA until packing labor, carrier rates, customer service time, and return handling are included in the model.

Common margin mistakes

  • Underestimating carrier rates by zone.
  • Not reserving for returns and refunds.
  • Forgetting packaging cost and handling time.
  • Comparing FBM and FBA without equal delivery expectations.

When to use this calculator
