Amazon FBA Calculator: Fees, Revenue & Profit
An Amazon FBA calculator adds up everything Amazon, your supplier and your ads take from a sale and shows what is left. Profit per unit is the selling price minus landed cost, referral fee, FBA fulfilment, storage, ads and the cost of returns. This free calculator does that sum for you before you buy inventory.

Assumptions and open items
- Prices are in US dollars. Sales tax is excluded: Amazon collects and remits it as marketplace facilitator.
- Fee rates last updated: 15 October 2026, from Amazon's Seller Central fee pages. Fulfilment rates are the 2026 rate cards.
- The Jan to Sep card uses the off-peak fulfilment rate cards (January 15 to October 14) and off-peak storage rates. The Oct to Dec card uses the peak rate cards (October 15 to January 14) and the October to December storage rates. The two calendars differ by two weeks, so the peak card is an approximation.
- The 3.5% fuel and logistics surcharge is added to the fulfilment fee.
- On a refund, Amazon keeps the lesser of $5.00 or 20% of the referral fee and refunds the rest. The fulfilment fee is 100% lost. Ad spend, storage and any returns processing fee are not recovered.
- Sellable returns go back into stock, so their cost and placement fee are not lost. Unsellable returns lose the unit's cost, less 0% recovered.
- Ads are charged on every order placed, including orders that are later returned. The seller plan fee is spread over every order.
- Storage is cubic feet × the monthly rate × days in the fulfilment centre ÷ 30. The aged-inventory surcharge is charged once for a unit aged 181 days or more.
- No minimum dimension is applied to dimensional weight. Amazon's pages give two examples that disagree, so verify the shipping weight of bulky and apparel items in Seller Central.
- Size-tier limits come from Amazon's inbound placement page, not the product size tier page. Pick a tier manually if yours differs.
- The returns processing rate card has two columns with no headers on the page. We read the left column as apparel and shoes and the right as everything else, which matches Amazon's worked examples.
- Amazon's aged-inventory page contains an example that contradicts its own formula. We follow the formula and charge one assessment per unit.
- Not modelled: Disposal and removal order fees, Overmax handling, SIPP (ships in product packaging) fees, Lithium battery and special handling fees, FBA dangerous goods program fees, Amazon Business referral rates, and The 22% veterinary diets rate in Pet Products. Amazon can also re-measure your items. Use "Other Amazon fees" for any that apply.

Start free trialAmazon FBA profit calculator: profit, margin and ROI per unit
The headline figure is net profit per order placed. It is an expected value: some of the units you sell come back, and a returned order costs money differently from a kept one, so the calculator works out both and weights them by your return rate.
- Net margin is net profit divided by the selling price.
- Net ROI is net profit divided by your landed cost: product cost plus duty, freight, inbound shipping and prep.
- Gross profit is what is left after landed cost, referral and fulfilment fees, before storage, ads and returns.
- Break-even price is the lowest selling price at which net profit reaches zero, with everything else held fixed.
- Break-even TACoS is the most you can spend on ads, as a share of price, before the product stops making money.
The coloured band reads the net margin: Great at 40% or more, Good from 25%, Acceptable from 15%, Riskier from 10% and Risky below that. It is a rule of thumb for a quick read, not a verdict on a product. "What moves your profit" shows which single change helps most.
FBA fee breakdown: referral, fulfilment, storage and more
Amazon charges FBA sellers several fees. The calculator works out each one from your category, price, size, weight and how long stock sits, and you can override any of them. The sample product is a large standard item at $34.99.
| Fee | How it is charged | Sample product |
|---|---|---|
| Referral fee | A percentage of the item price, by category (Home and Kitchen: 15%), with a $0.30 minimum in most categories | $5.25 |
| FBA fulfilment fee | By size tier, shipping weight and price band ($10 and $50), plus a 3.5% fuel and logistics surcharge. Peak rate cards apply from October 15 to January 14 | $7.38 (peak $7.94) |
| Monthly storage | $0.78 per cubic foot per month for standard-size items ($2.40 from October to December) | $0.29 |
| Aged-inventory surcharge | Per cubic foot for units held 181 days or more, rising with age | None at 45 days |
| Inbound placement fee | None with Amazon-optimised splits (5 or more identical cartons). A per-unit fee if you choose minimal or partial splits | $0.00 |
| Low-inventory-level fee | When your days of supply stay under 28 on eligible items | None |
| Returns processing fee | On returns above a category threshold (8.1% for Home and Kitchen), and on every return for apparel and shoes | $0.51 per returned unit |
| Refund administration fee | On a refund Amazon returns the referral fee minus the lesser of $5.00 or 20% of it | $1.05 per refund |
| Seller plan | Professional: $39.99 a month. Individual: $0.99 per item sold | $0.13 per order at 300 orders a month |
These come from Amazon's own Seller Central pages, last checked 15 October 2026: the FBA fulfilment fee changes, referral fees, monthly storage fees and the Selling on Amazon fee schedule. Confirm anything that matters against your own Seller Central account, and use the override fields for fees we do not model.
Amazon FBA revenue calculator: what you actually keep
Revenue is not what you keep. Of every $100 the sample product sells for, $36 goes to Amazon's referral and fulfilment fees, $31 to the cost of getting the unit to Amazon, and $10 to ads. Storage, returns and the seller plan take a little more, leaving $16.
The three columns compare how the same product performs fulfilled by Amazon in the off-peak months, fulfilled by Amazon from October to December, and fulfilled by you (FBM). On the sample, FBA earns $5.50 per order in the off-peak months, $4.34 in the peak months, and FBM earns $4.14. FBM saves the fulfilment fee but you pay for picking, packing and shipping yourself, including the return shipping when a unit comes back, so the winner depends on your own costs. Change the FBM inputs under More assumptions to match yours.
Amazon's Revenue Calculator vs this calculator
Amazon's own Revenue Calculator in Seller Central is the reference for the fees on a specific listing. If you are searching for the FBA calculator in Seller Central, that is the tool: use it to confirm the exact referral and fulfilment fee for an ASIN.
This calculator starts from the same fee schedule and goes further down the page to what you keep:
- Landed cost with freight and import duty or tariff, so the margin reflects what the unit really cost you.
- Advertising as TACoS or dollars per unit, with a break-even TACoS.
- Returns modelled properly: the refund, the refund administration fee, returns processing, and sellable versus unsellable units.
- Break-even price, a profit-against-price chart and a sensitivity list for price, cost, returns and ads.
- FBA off-peak, FBA peak and FBM side by side.
A practical workflow: check the fees for a listing in Amazon's tool, then use this one to see whether the product still makes money once ads, returns and your own costs are in.
How to use the calculator
- Pick the category and enter the selling price, then the packed size and weight of one unit. The size tier appears in the result.
- Enter your product cost, any import duty, freight to the US, inbound shipping to Amazon and prep. Together these are your landed cost.
- Set your TACoS, return rate, the share of returns you cannot resell, your monthly orders and how many days a unit sits in the fulfilment centre.
- Read the net profit, margin, break-even figures and the three scenarios. Change one input at a time to see what moves them.
- Open More assumptions to override any fee, choose an inbound placement option, add a low-inventory fee, or adjust the FBM comparison.
- Copy the link to keep or share your numbers. Nothing you type is saved on our servers.
Worked example
The calculator opens with a sample product so you can see every step. It is an illustration, not a forecast or a real listing: a 12 × 9 × 4 inch, 3.5 lb item in Home and Kitchen, priced at $34.99, with a landed cost of $10.90 ($9.50 product cost, $0.80 freight, $0.40 inbound, $0.20 prep), 10% TACoS and a 9% return rate.
- After landed cost, the referral fee ($5.25) and the fulfilment fee ($7.38), gross profit is $11.46, a 32.8% gross margin. This is the number many sellers stop at.
- Storage and ads take that down to $7.67 on a unit that is kept.
- Returns cost another $2.03 per order placed, and the seller plan takes $0.13, leaving $5.50 of net profit, a 15.7% net margin.
The gross margin looks twice as healthy as the net margin. The gap is ads, storage and returns, which is why the calculator includes them.
Costs that make a product look more profitable than it is
- Leaving out ads. New listings often need heavy ad spend. Enter the TACoS you expect to run, not the one you hope for.
- Treating a return as a refund only. On a return you lose the fulfilment fee and the ad spend, pay a refund administration fee, and for unsellable units lose the product itself.
- Forgetting that fees step. Fulfilment fees change at $10 and $50, and referral fees in some categories change at set prices. A small price change can cost more than it earns.
- Using the wrong size tier. A packed size or weight just over a limit moves the item into a dearer tier. Measure the packed unit, not the product.
- Ignoring storage time. Slow sellers pay monthly storage, and from 181 days an aged-inventory surcharge. Raise the days in the fulfilment centre for slow movers.
- Skipping tariffs and freight. Import duty and freight are part of landed cost. Enter your effective duty rate.
- Counting peak-season costs as off-peak. From October 15 fulfilment fees rise and storage costs more. Check the peak column before you plan Q4 stock.
Frequently asked questions
It adds up what Amazon, your supplier and your ads take from a sale, and shows what is left. You enter the price, size, weight and your costs, and the calculator applies the referral, fulfilment, storage and other FBA fees, plus ads and returns, to give a profit per unit.
Take the selling price and subtract landed cost, the referral fee, the FBA fulfilment fee, storage and ad spend. Then allow for returns, because a returned order refunds the sale. The calculator does each step and shows the result per order and per month.
The main ones are the referral fee, the FBA fulfilment fee and monthly storage. Depending on your situation you may also pay an inbound placement fee, a low-inventory-level fee, an aged-inventory surcharge, a returns processing fee and a refund administration fee, plus your seller plan.
Amazon's Revenue Calculator estimates fees and the payout for a listing. This calculator goes on to landed cost, ads, returns, break-even price and TACoS, and compares FBA with FBM, so you see profit rather than just fees.
Amazon's Revenue Calculator is in Seller Central. Search for it in the Seller Central search bar. Use it to confirm the fees for a specific ASIN, then use this calculator to see the profit after ads, returns and your own costs.
Yes. Ads go in as TACoS or dollars per unit, and the result includes a break-even TACoS. Returns use your return rate, the share you cannot resell, the refund administration fee and, above a category threshold, the returns processing fee.
The maths is tested against the worked examples on Amazon's own pages, and the fee tables are dated. Rates were last checked on 15 October 2026. Amazon changes fees often, so confirm anything important in Seller Central and override any fee you know to be different.
Yes. It is free, needs no login and does not save what you enter.
There is no single answer, but after ads and returns a net margin of 15% or more is a reasonable target, and under 10% leaves little room for a bad month. The band in the results uses those thresholds. Your own cash and risk tolerance matter more than a benchmark.
Measure and weigh the product in its final packaging. Amazon sorts items into small standard, large standard, small bulky, large bulky and extra-large by their longest, median and shortest sides and by weight. The calculator detects the tier from your size and weight, and you can override it.
It depends on your own fulfilment costs, your price and your return rate. FBM avoids the fulfilment fee but adds picking, packing, shipping and return shipping. Enter your real FBM costs and compare the three columns.
Duty is part of landed cost, so every dollar of duty comes straight off profit. Enter your effective duty rate as a percent of product cost, and the calculator adds it to the landed cost for FBA and FBM alike.
