TACoS (Total Advertising Cost of Sales)
TACoS (Total Advertising Cost of Sales) is the ratio of total ad spend to total revenue on Amazon — including organic sales, not just ad-attributed sales. If you spend $100 on ads and your listing generates $1,000 in total revenue, your TACoS is 10 percent. It is the clearest single indicator of long-term advertising health for Amazon sellers.
Why it matters for Amazon sellers
TACoS reveals whether your advertising is building organic momentum or just buying transactions. A declining TACoS paired with stable or growing revenue means your ads are driving organic rank and customers are finding you without clicking paid placements. A rising TACoS means you are becoming increasingly dependent on paid traffic, which is an unsustainable trajectory for most categories. For launch-phase products, high TACoS is expected — you are paying to build rank and review velocity that do not exist yet. For mature products, TACoS should trend down over months and quarters as organic conversion improves and brand awareness grows. Most healthy Amazon businesses run between 5 and 15 percent TACoS depending on category competitiveness and growth stage. Above 20 percent on mature products usually indicates listing quality issues, weak brand recall, or over-reliance on competitor-conquest keywords. Sophisticated sellers watch TACoS weekly and treat it as the real measure of PPC effectiveness, using ACoS only for tactical keyword decisions.

Frequently asked questions
What is TACoS in Amazon advertising?
TACoS (Total Advertising Cost of Sales) is your total ad spend divided by your total revenue — not just ad-attributed revenue. It shows what percentage of all your sales revenue goes to advertising, giving a complete picture of ad efficiency.
What TACoS percentage should I aim for?
Most healthy Amazon businesses target TACoS between 5 and 15 percent, but the right number depends on your category, margins, and growth stage. Launch-phase products will have higher TACoS. Mature products should see TACoS decline over time as organic sales grow.
How do I lower TACoS without losing sales?
The path is better organic performance — improved listings, earned reviews, and higher conversion rates — not just lower ad spend. Cutting ads without fixing the conversion fundamentals usually tanks total revenue faster than it lowers TACoS. AI systems that coordinate listings (Brett), PPC (Marko), and pricing (Oracle) can lower TACoS while growing revenue because they improve all the inputs together.
