Amazon Break-Even ACOS Calculator
Find break-even ACOS, target ACOS, and max CPC from margin and conversion.
How to use this tool & where to get the input
Input — from your Amazon seller account
Get your per-unit Amazon fees from the profit calculator on this site, or from Reports → Fee Preview.
Steps- Enter price, cost and fees per unit.
- The result is the maximum ACOS at which an ad sale still breaks even — above it, every ad sale loses money.
Type your own, or get the exact figure for this SKU from the Amazon Profit Calculator — the default is only a placeholder.
Your own target — the default is a starting point, not a recommended margin.
Your price includes GST that you pay to the government, less the GST on Amazon's fees you claim back. Pick “Not GST-registered” if neither applies to you.
