Amazon FBA profit: fees and costs to include
A selling price and referral percentage are not enough for a useful FBA estimate. Start with the fee preview for the exact product.
Open the Amazon FBA Profit Calculator →Obtain a fee estimate for the actual product
Use Amazon's official Revenue Calculator or an authorised account fee preview for the correct marketplace. Enter the packed product measurements, weight and relevant category there. Keep the result and its date; two products with the same selling price can have different fulfilment costs.
Clear Takings requires the applicable referral and fulfilment inputs rather than inventing a size tier. If Amazon gives a tiered or minimum referral charge, use an exact manual amount with the percentage zero, or a properly calculated effective rate for the specific price. Recheck it when the price changes.
Add the cost of getting saleable stock into fulfilment
Your supplier's unit price is one part of sourcing cost. Freight, import costs you bear, preparation, labels, protective packaging and delivery into the fulfilment network can add to it. Spread genuine batch costs over saleable units and identify which charges have already been included by a supplier or service.
Enter per-unit fulfilment, storage and inbound assumptions in their relevant fields. Put tax-inclusive costs in the estimate where tax is not recoverable, or a consistent recoverable-tax basis where established. The fee VAT field applies to the marketplace/payment fee ledger; it does not automatically add VAT to every fulfilment input.
Make storage and returns explicit assumptions
Choose a stock period that matches how quickly you expect the product to sell. A product that sits for longer can have a very different storage cost from one that turns over promptly. Account-specific storage, ageing and returns charges should come from current official information, not a remembered average from another product.
Test an ordinary sale, a slower-selling stock scenario and a return allowance. Keep the assumptions separate so a change in advertising cost is not confused with a change in storage. A single estimate is a starting point for a sourcing decision, not a guarantee of demand.
Check the contribution before increasing the purchase order
For illustration, £25 revenue less £6 sourcing, £3.20 fulfilment, £0.30 allocated storage and £3.75 referral fee leaves £11.75 before packaging, advertising and other charges. Adding £4 advertising per sale reduces that figure to £7.75. Those amounts are examples, not an Amazon rate card.
Compare the amount remaining with stock cash requirements and the sales volume needed to cover wider costs. A percentage margin alone will not show how much cash is committed to a large shipment. Keep a downside scenario alongside the expected case.
A worked example
A £25 illustrative sale with £6 sourcing, £3.20 fulfilment, £0.30 storage and £3.75 referral fees leaves £11.75 before other costs. These inputs are not an official rate card.
Before you use the result
- Use the correct UK or US official product estimate.
- Keep packed measurements and the estimate date.
- Include preparation and inbound costs once.
- Choose a realistic storage period.
- Add advertising and a documented return allowance.
- Test the cash required for the intended stock order.
Common questions
Can dimensions alone establish my FBA fee here?
This release does not infer Amazon size tiers. Use the official calculator or authorised account fee preview and transfer the applicable charges. That avoids presenting an unsupported fulfilment estimate as an exact fee.
Is referral fee the same as fulfilment fee?
They cover different charges. Enter referral separately from fulfilment and any storage/inbound assumptions. Check which amounts are already in the official estimate to avoid repeating them.
