Amazon FBA Calculator - Free 2026 Tool
Free Amazon FBA calculator with the current 2026 US fee schedule built in. Look up any ASIN to auto-fill price, dimensions, sales and competition, then tweak the numbers live.
This result is an estimate for one unit at the rates you entered. For real profit after every fee Amazon actually charged you, across every SKU and marketplace, see Amazon P&L analytics.
Think of it as the Amazon Seller Central calculator that Seller Central itself does not give you: the same per-unit fee math, plus break-even and ACoS. For real settlement-level fees across your full catalog, Nova pulls actual fees from your Seller Central account.
Weighing a Vendor Central purchase order against selling the same unit yourself? The 1P vs 3P margin calculator runs this same fee engine on the 3P side and puts a negotiated wholesale price next to it.

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.
| Factor | FBA | FBM |
|---|---|---|
| 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, seller fee calculator or FBA profit calculator?
Three different questions, all answered on this page. Jump to the one you came for.
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.
The rate cards behind these numbers
Every rate on this page comes from Amazon's own published US schedules, read on September 21, 2026. Amazon changes them, so check the source before you commit to a price.
