Amazon FBA profit & import-cost planner
Use your Amazon fee preview to calculate US FBA profit after product cost, freight, optional import duty, storage, returns and advertising. All amounts in USD.
US marketplace only. Enter your account-specific fee preview. Example fee inputs are illustrative and are not published Amazon rate quotations.
US marketplace, USD. The numbers shown on first load are an example, not Amazon quotes. Enter the fulfilment fee from your ASIN fee preview, including any surcharge. This avoids guessing a size tier or using an unverified fee table.

| Step | Working | Result |
|---|---|---|
| Selling price | $29.99 | |
| Marketplace commission | 29.99 × 15% | -$4.50 |
| Fulfilment | -$4.50 | |
| Storage per unit | -$0.20 | |
| Cost of goods | -$6.00 | |
| Inbound shipping | -$1.20 | |
| Returns at 5%Per return: handling + refund admin + written-off stock + the outbound fulfilment fee you do not get back + the 100% of commission the marketplace keeps. | 13.40 × 0.05 | -$0.67 |
| Advertising per unit | -$3.00 | |
| Net profit per unit | 29.99 − 20.07 | $9.92 |
| Net marginMargin is measured against net revenue, so it stays comparable across tax regimes. | 9.92 ÷ 29.99 × 100 | 33.08 % |
| Monthly profit at 300 units | 9.92 × 300 − 39.99 fixed | $2,936.49 |
Before committing to a purchase, reconcile these inputs to your Amazon fee preview and plan. Sales tax collected for a tax authority is not seller revenue. This model excludes income tax and cash-flow timing.
Step 2 of 4 — I am selling on a marketplace
What is left after the platform takes its cut?
Bring a fee preview, not a guessed rate
Open the ASIN fee preview in your US seller account and enter the fulfilment charge including applicable surcharges. Add storage and other per-unit costs separately so the same charge is not counted twice. The worksheet does not identify a size tier, connect to your account or convert currencies.
A reproducible import example
For 100 units at $5 each, $1.20 freight per unit, a confirmed 10% duty on goods and $30 total clearance, landed cost is ($500 + $120 + $50 + $30) / 100 = $7. Turn on import mode and enter those inputs. At $20 revenue, 15% referral, $4.50 fulfilment, $1 advertising and no other charges, the contribution is $4.50 before plan fees and returns. With the Individual plan selected, $0.99 per item reduces it to $3.51.
Use the result to make a buying decision
Stress-test the product by raising landed cost and returns before agreeing a supplier order. A positive per-order estimate can coexist with a cash shortage because freight and inventory are paid before sales arrive. The conservative return model assumes no marketplace fee refund; reconcile actual reimbursements separately. Non-US marketplaces, dangerous goods, special programmes and income taxes need their own analysis.
Questions people ask about this
Answers written from the published rules, not from other people's summaries of them. Every figure quoted below is listed with its source at the foot of this page.
Every formula on this siteWhere do I get the fulfilment fee?
Use the current fee preview for the ASIN in your seller account. Enter the final per-unit fulfilment charge including surcharges, and enter storage, placement and preparation separately where they are not included.
Does this calculate a size tier?
No. The public worksheet uses your actual quoted fee because size tiers, special programmes and applicable rate periods affect the invoice. Confirm the packaged dimensions in Seller Central if a quoted fee seems wrong.
How do I include import duty?
Turn on the import-cost option, enter the supplier price, shipment quantity, international freight, clearance and the combined duty rate applicable to the commodity and origin. The resulting landed cost replaces cost of goods and inbound freight.
Can I use this outside the US?
This worksheet models the US marketplace in US dollars. A currency symbol change would not reproduce another marketplace fee schedule. For a different market, use the general profit tool with your locally applicable costs.
What happens when a customer returns an order?
The model spreads the entered return rate, handling cost and unsellable stock assumption across orders, with no marketplace fee refund assumed. Compare that conservative result with your actual reimbursements and refund administration fees.
