Visit ShopifyUse this calculator before setting a Amazon FBA 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
- Enter a realistic sale price and landed product cost.
- Add shipping cost, ad cost per order, and a return reserve.
- Check whether net margin stays positive after fees and tax reserve.
- Compare the same product across related marketplaces and countries.
Profit planning example
For example, a $49.99 product with $16 landed cost, $7 shipping or fulfillment cost, $5 ad cost, and a 3% return reserve can look profitable before fees but lose several margin points after marketplace and reserve costs.
Common margin mistakes
- Ignoring FBA size and weight tiers.
- Using one referral fee for every category.
- Forgetting storage, returns, removals, and ad cost.
- Pricing only against competitors instead of target margin.
