Amazon FBA Fee & Profit Calculator
Amazon FBA's referral fee alone runs 8-45% of your selling price depending on category (commonly 15% for general goods), on top of a separate per-unit fulfillment fee. The oft-cited seller complaint — a calculator promising $8-10 net profit that lands closer to $5 — usually comes from storage fees, aged-inventory surcharges, or VAT left out of the estimate.
Calculate your true net profit on Amazon FBA — referral fee, fulfillment fee, shipping to Amazon, and product cost — the real math behind the gap between what a calculator promises and what actually lands in your payout.

Informational only — helps you find the right row in Seller Central. Amazon restructured FBA fulfillment fees in 2026 into a size tier × weight × selling-price system (plus a 3.5% fuel surcharge), and exact per-tier rates aren't published outside Seller Central, so this selector doesn't change the math below. Enter your real fee in the field underneath from Seller Central > Reports > Fulfillment > Fee Preview.
Amazon's per-unit pick, pack, and ship fee for your size tier above, including any fuel surcharge — pull the exact current number from Seller Central's Fee Preview report rather than relying on this field's default, since 2026 rates vary by weight and selling price and change frequently.

How the Amazon FBA Fee & Profit Calculator works
Enter your selling price, product cost, per-unit shipping to Amazon, referral fee percentage, and FBA fulfillment fee. The calculator subtracts all fees and costs from your selling price to show net profit per unit and your true net margin — the number that matters after Amazon takes its cut.
Use Amazon's own Revenue Calculator inside Seller Central to find your product's exact referral and fulfillment fee rather than relying on the typical defaults here, since both vary by category and by size/weight tier — a few percentage points or a dollar or two of difference compounds fast across volume.
Who this is for
For Amazon sellers evaluating a new product before sourcing it, or checking whether an existing FBA listing is still profitable after fee changes. It's also for anyone who's felt the specific frustration seller communities describe constantly: a fee calculator — sometimes even Amazon's own — says a product nets $8 to $10 per unit, and then real payouts land closer to $5, sometimes less. That gap is rarely one big error; it's usually several smaller line items that a simplified calculator quietly leaves out — storage fees, aged-inventory surcharges, and VAT, none of which show up in a referral-fee-and-fulfillment-fee-only estimate. This calculator is deliberately scoped to referral and fulfillment fees, the two charges applied to every single sale, and says so plainly rather than pretending to be a complete P&L — see the fee breakdown below for what else to budget for separately.
Worked example
You sell an item for $29.99, it costs $8 to make, and $1.20 to ship to Amazon. The referral fee is 15% ($4.50), and the FBA fulfillment fee is $5.50. Net profit = $29.99 − $4.50 − $5.50 − $8 − $1.20 = $10.79. Net margin = $10.79 / $29.99 × 100 ≈ 36% — a healthy margin after Amazon's two per-sale fees. That $10.79 isn't necessarily what lands in your bank account, though. If this unit sits in an FBA warehouse in October, November, or December, standard-size storage jumps from $0.78 to $2.40 per cubic foot — roughly triple — which can turn a comfortable margin into a thin one for anything that doesn't sell through quickly during Q4. And if you're VAT-registered anywhere this product ships, VAT isn't in this calculation at all — deduct it separately before treating $10.79 as your real take-home, since even Amazon's own official calculator excludes VAT and overstates profit for sellers who owe it.
How Amazon fees are actually calculated
Amazon's FBA fees aren't one number — they're a stack of at least three separate charges, and a 2026 review finding that budget calculators handle only three or four of the seven-plus real fee categories is a common, documented complaint.
The three core charges:
- Referral fee — a percentage of your selling price that varies enormously by category: electronics and computers sit around 8%, most general categories (Home, Kitchen, Toys & Sports) run 15%, and device accessories can run as high as 45%, with a $0.30 minimum regardless of category.
- FBA fulfillment fee — a flat per-unit charge for Amazon to pick, pack, and ship the order. It's not a percentage, and it scales with your product's size and weight tier, roughly $3.06–$3.22 for small standard items up to $3.86–$6.75 for large standard ones.
- Storage fee — a monthly fee per cubic foot of space your inventory occupies in an Amazon warehouse, billed separately from the per-sale fees above and easy to forget when pricing a listing.
Storage is where the seasonal shock lives — standard-size storage costs $0.78 per cubic foot from January through September, then triples to $2.40 per cubic foot from October through December, Amazon's peak-season pricing. Inventory that sits unsold past 181 days can also trigger an aged-inventory surcharge on top of regular storage.
2026 brought additional pressure on top of all this:
- An average $0.08/unit fulfillment fee increase, effective mid-January.
- A 3.5% fuel and logistics surcharge, added in April.
Individually modest, but sellers report the stacked effect is closer to 8-10% higher costs overall — not the smaller number any single line item suggests on its own.

Frequently asked questions
What fees does Amazon charge FBA sellers?
The two main fees are the referral fee (a percentage of the sale price, typically 8-17% depending on category) and the FBA fulfillment fee (a flat per-unit fee based on size and weight for picking, packing, and shipping). There are also optional storage and long-term storage fees not included here.
How do I find my exact FBA fulfillment fee?
Amazon's Revenue Calculator (in Seller Central) gives the exact fee for your product's size tier and weight. Use that exact number here for the most accurate profit estimate — the default in this calculator is just a typical example.
Why doesn't this calculator pick my fulfillment fee automatically from my size tier?
Amazon restructured FBA fulfillment fees for 2026 into a three-dimensional system — size tier, weight band, and selling-price band (under $10, $10-$50, over $50) — and layered a 3.5% fuel and logistics surcharge on top starting in April 2026. The size tier selector above is there to help you find the right row in your own account, but the exact per-tier, per-weight, per-price dollar amounts are published inside Seller Central's Fee Preview report, not on a public page — so rather than bake in numbers that could be stale or wrong the moment Amazon adjusts them again, this calculator asks for your real fulfillment fee directly. Copy it from Seller Central > Reports > Fulfillment > Fee Preview for an accurate result.
Does this include storage fees?
No — this calculator covers referral and fulfillment fees only, which are charged on every sale. Monthly and long-term storage fees depend on how much inventory you hold and for how long, and should be factored in separately for a full picture.
What's a good net margin for an Amazon FBA product?
Most successful FBA sellers target at least 20-30% net margin after all fees, since it needs to absorb PPC ad spend, returns, and seasonal price competition. Margins under 15% are considered risky for a sustainable FBA business.
Why is my referral fee different from what I expected?
Referral fee percentages vary by product category — electronics might be 8%, while most other categories are 15%. Double-check your category's exact rate on Amazon's fee schedule and adjust the referral fee field accordingly.
Why does my actual FBA payout always come in lower than what a calculator promised?
This is one of the most common complaints in Amazon seller communities, and it's rarely a single dramatic fee — it's usually several smaller ones stacking up that a simplified calculator (including, in places, Amazon's own) leaves out. Referral and fulfillment fees, the two this calculator covers, apply to every sale, but storage fees, aged-inventory surcharges after 181 days, and VAT (which even Amazon's official Revenue Calculator excludes) all reduce what actually lands in your account. A product that 'nets $8-10' on a basic calculator can easily clear closer to $5 once those are added back in — budget for them separately rather than treating a referral-and-fulfillment-only number as your final take-home.
Does Q4 storage really triple my costs?
For standard-size inventory sitting in an Amazon fulfillment center, yes — storage jumps from $0.78 per cubic foot (January through September) to $2.40 per cubic foot (October through December), Amazon's published peak-season rate. It only applies to inventory physically stored during those months, so it matters most for sellers who ship in ahead of the holiday season and hold stock through Q4 — if your inventory turns over quickly and rarely sits in a warehouse in Q4, the impact is smaller. For anything you expect to hold through October–December, run your storage-fee math at the $2.40 rate, not the $0.78 one, before finalizing pricing.
Do I need to add VAT on top of this calculator's result?
If you're VAT-registered — most commonly for sellers shipping into the UK or EU — yes, this calculator doesn't account for VAT at all, and neither does Amazon's own official Revenue Calculator, which is a documented, widely-cited gap that overstates profit for anyone who owes it. Treat the net profit shown here as pre-VAT, and deduct your applicable VAT rate separately based on where the sale is fulfilled and shipped, since VAT obligations depend on jurisdiction-specific rules this calculator has no way to model generically.
