How it works
Profit per unit = selling price − referral fee − FBA fees − landed product cost − advertising.

Before you decide
This is a planning estimate, not an Amazon fee quote. Fulfillment, storage, returns, placement, aged inventory, taxes, and category rates may change the result.

Working note
Make the estimate useful.
FBA profitability is best modeled per sellable unit. Start with landed product cost, then separate Amazon referral fees, fulfillment charges, storage, advertising, and inbound freight. That makes it easier to see which lever is actually reducing margin.
Questions from the desk
Amazon FBA Profit Calculator FAQ
Is this the same as Amazon's revenue calculator?
No. This is an independent planning tool with editable assumptions. Amazon's own account tools remain the source for account-specific fee estimates.
What is break-even ACoS?
It is the share of sales revenue available for advertising before the modeled unit stops contributing profit.
Where should coupons and discounts go?
Reduce the selling price to the amount you expect to receive, then add any coupon redemption charge to storage and other fees.
Keep checking the whole margin.
