How it is calculated

Amazon fees = price × referral fee % + FBA fee + storage per unit.

Profit before ads = price − product cost − Amazon fees − other costs.

Profit per unit = profit before ads − ad spend per unit. Ad spend per unit is your total ad spend divided by all units sold, ads and organic, so it matches TACOS.

Break-even ACOS = profit before ads ÷ price: the highest ACOS at which an ad sale still makes no loss.

Questions sellers ask

How do I calculate FBA profit?

Price minus the referral fee, the FBA fulfilment fee, storage per unit, your product cost (with inbound shipping), any other cost per unit and advertising per unit. This calculator does it per unit and per month.

What is a good profit margin on Amazon FBA?

Many sellers aim for 15% to 25% net margin after all fees and advertising, but categories differ. What matters most is that every product stays profitable after its ads: compare its break-even ACOS with its real ACOS.

Where do I find my exact FBA fee?

In Seller Central's fee preview or the revenue calculator for each ASIN. Fees depend on size, weight, category and marketplace, and Amazon updates them, usually once a year.

Does this include VAT or sales tax?

Enter prices and costs the way you account for them. In marketplaces with VAT, enter the price without VAT if you pay VAT on it, or add VAT to other costs per unit.
