See your real profit after Amazon's referral fee, fulfillment fee, and your own costs — by category and by weight.
Referral fee is estimated as a percentage of your selling price, based on the Amazon category you choose — most categories are 8–17%, with a common minimum referral fee that applies to very low-priced items.
FBA fulfillment fee is estimated from your item's weight and size tier — larger/heavier items cost more to pick, pack, and ship.
FBM skips Amazon's fulfillment fee, but you pay your own shipping cost directly, which this calculator asks for.
Note: Amazon updates its fee schedule periodically and fees vary by exact dimensions, marketplace, and product specifics. Treat these numbers as a close estimate for planning — always confirm exact fees for a listing in Seller Central before pricing decisions.
