Amazon FBA Calculator 2026 Fees

Calculate true FBA profit per unit, fees, break-even, and FBA vs FBM comparison

What is this? Amazon FBA fees are complex and often surprising. Referral fees (15%), fulfillment fees ($3.22-$6.50+ per unit), storage fees ($0.78-$2.40/cu ft/mo), plus closing fees, returns, and PPC ads can make a "profitable" $29 product actually lose money. This calculator shows the complete picture — every fee, every cost — so you know before you list.

Who it's for: Amazon FBA sellers, private label entrepreneurs, and resellers evaluating whether a product will actually make money on Amazon.
