Estimate Amazon FBM profit in the United States with referral fees, seller-paid shipping, ad cost, return reserve, tax reserve, and net margin.
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.
FBM orders often look stronger than FBA until packing labor, carrier rates, customer service time, and return handling are included in the model.
Use this page before ordering inventory, changing price, increasing ad spend, or expanding to another sales channel. Run conservative scenarios first, then compare the result with related calculators and official marketplace guidance.
