FBA vs FBM: which fulfillment wins for your product?
FBA hands the operation to Amazon and charges flat per-unit fees. FBM keeps you in control of packing and shipping. The right answer depends on weight, margin and sales predictability.

|---|---|---|
| Per-unit cost | Flat 2026 fulfillment fee + storage | Your own shipping rate, no storage fee |
| Prime eligibility | Automatic | Only via Seller Fulfilled Prime |
| Best for | Light, fast-moving SKUs | Heavy, slow-moving, oversize items |
| 2026 fee exposure | Placement, LIL and aged surcharge apply | None of the new FBA-only fees apply |

Amazon fee calculator
What Amazon charges on one sale: the referral fee set by category, the FBA fulfilment fee set by size tier and shipping weight, and monthly storage. Work each one out in the referral fee, fulfilment fee and storage fee sections.
Amazon seller fee calculator
The same per-sale fees plus the selling plan itself: $39.99 a month on the Professional plan, or $0.99 per item sold on the Individual plan. The plan fee sits outside the per-unit maths, so add it to your fixed monthly costs rather than to a single unit.
FBA profit calculator
What is left after the fees, your landed cost, ad spend and refunds. The profit and margin section reports the dollar profit and the margin percentage side by side, with CM1, CM2 and CM3 in between.
