How Amazon FBA fees work
FBA profit has four moving parts: the referral fee (a percentage of the sale — 15% for most categories), the per-unit fulfillment fee set by your product's size tier and weight (2026: about $3.11–$3.70 small standard, $3.73–$6.97 large standard, from $9.66 large bulky — plus a 3.5% fuel surcharge since April), monthly storage per cubic foot (roughly tripling October–December), and any PPC advertising you run.
This calculator stacks all four so you see true per-unit profit — pick the closest size tier, set your category's referral rate, and add your storage and ad cost per unit. For the referral-fee-only view, use the regular Amazon fee calculator.

Frequently asked questions
How much are FBA fees in 2026?+
Fulfillment: roughly $3.11–$3.70 for small standard items, $3.73–$6.97 for large standard (up to 3 lb), and from $9.66 for large bulky — plus a 3.5% fuel surcharge from 17 April 2026. The 15%-typical referral fee and monthly storage are separate.
What changed in Amazon FBA fees for 2026?+
Referral percentages stayed frozen, but fulfillment fees rose 3–5% across size tiers (about $0.08 per unit on average), and a 3.5% fuel & logistics surcharge was added from 17 April 2026.
Is FBA worth it versus shipping myself (FBM)?+
Compare your own cost to pick, pack, and post one unit against your size tier's FBA fee. FBA usually wins for small, fast-moving items (and adds Prime eligibility); FBM often wins for large, heavy, or slow-moving inventory where storage fees pile up.
Does this include the monthly storage fee?+
Add it via the storage-per-unit field: divide your monthly storage bill by units sold per month. Remember October–December storage rates are roughly triple the rest of the year.
