ACoS tells you about the ads. TACoS tells you about the business.

It is easy to run a tidy ACoS and still watch profit erode, because ACoS only sees ad-attributed sales. TACoS divides ad spend by all your sales, so it catches the case every operator dreads: paying for clicks on products that were already going to sell organically. Watch TACoS month over month — falling while sales hold is the signal that your rank is compounding.

Pair this with the break-even ACoS calculator to set a per-sale ceiling, then check your numbers against your category with the benchmark comparison.

FAQ

Common questions

TACoS (total advertising cost of sales) is ad spend divided by total sales, not just ad-attributed sales. It shows how much of your whole business depends on ads. A falling TACoS while sales hold or grow means your organic rank is doing more of the work — usually the healthiest signal in an Amazon account.
