- Advertising Spend ÷ Advertising-Attributed Sales
- Estimated non-ad sales
- Total Sales − Advertising-Attributed Sales
This tool never labels a TACoS "good" or "bad" against a generic industry rule. It only compares your number against a target or break-even TACoS you provide yourself. This is an estimate from the numbers you enter, not a review of your actual Seller Central account.
