Use this as a local planning estimate. Verify current fees, taxes, advertising, and overhead before making a pricing decision.
How the fee estimate works
Amazon fees use the editable referral rate, FBA fulfillment fee, and storage/other fees shown above, applied to the sale price. Product cost and inbound shipping are deducted after Amazon fees, and custom fees (added below) reduce profit directly. Break-even and target-profit prices solve against (1 − referral rate). Results are planning estimates; Amazon fees vary by category, size tier, program, and marketplace.

What Amazon charges sellers — Amazon sellers pay a referral fee on each sale, commonly 15% across most categories, plus FBA fulfillment fees per unit and monthly storage for inventory in FBA. Use this Amazon seller fee calculator to see how referral and fulfillment fees split a sale, and what price your target profit actually requires.
Planning estimate only. Platform fees, taxes, payment costs, and policies can change; verify current terms before pricing.

What does this calculator estimate?
Selling on Amazon with FBA costs roughly $22.65 for a $35 product, leaving $12.35 in contribution profit. That figure comes from the formula: Contribution profit = sale price − referral fee − fulfillment fee − storage/other fees − product cost − inbound shipping. Break-even and target-profit prices solve the same model in reverse. For a $35 product with a 15% referral fee ($5.25), $4.75 fulfillment, $0.25 storage, $11.50 product cost, and $0.90 inbound shipping, the contribution profit is about $12.35 before advertising, returns, taxes, and overhead.

How do referral fees and fulfillment fees work together?
Referral fees are a percentage of the customer-facing sale price, while fulfillment fees are a separate per-unit cost. The calculator keeps them separate so you can see whether a margin problem comes from the product price, the percentage fee, or a fixed fulfillment charge. Check the current category and fulfillment rules before using any estimate for a live listing.
Why is break-even price different from a target-profit price?
Break-even covers the modeled product and marketplace costs with zero contribution profit. A target-profit price solves the same cost model in reverse after adding the profit you want to keep. Neither result includes costs you have not entered, such as advertising, returns, taxes, packaging, or overhead.
What should you verify before pricing a listing?
- Current category referral rate and any minimum fee
- Fulfillment or shipping charge for the exact size and weight tier
- Storage, inbound shipping, advertising, returns, tax, and packaging assumptions
- Whether the price still clears your target profit after every modeled cost
How this calculator works
Formula
Contribution profit = sale price − referral fee − fulfillment fee − storage/other fees − product cost − inbound shipping. Break-even price and target-profit price solve the same model in reverse.
Worked example
For a $35 product with 15% referral fee, $4.75 fulfillment, $0.25 storage, $11.50 product cost, and $0.90 inbound shipping, contribution profit is about $12.35 before advertising, returns, taxes, and overhead.
Assumptions to verify
- User-entered fee values must be checked against current Amazon marketplace/category/fulfillment rules.
- Advertising, return loss, tax, packaging, and overhead are not included unless entered separately.
- This version is editable-arithmetic; category/size-tier intelligence is a future flagship-tool upgrade.
Frequently asked questions
Does this support every Amazon marketplace?
The arithmetic is general, but you must enter fees and currency appropriate to the marketplace.
Is advertising included?
Not in the default fields. Subtract expected ad cost when evaluating true contribution profit.
Why can actual FBA fees differ?
Size tier, shipping weight, storage period, category, and program rules affect charges.
What is an Amazon referral fee?
The referral fee is the percentage Amazon charges per sale. It varies by product category (commonly 8–15%) and is calculated on the item's sale price. This calculator's referral-rate input lets you enter your category's rate to see its effect on net profit.
How do I calculate my Amazon seller fee and profit?
Subtract the referral fee, fulfillment fee, storage and other fees, product cost, and inbound shipping from your sale price. This calculator does that for you with editable assumptions so you can model FBA vs FBM or different categories and see the resulting net profit per sale.
