What's a Good TACoS for Amazon Sellers in 2026?

A good Total Advertising Cost of Sales (TACoS) for an Amazon seller in 2026 is 5-10% for a mature, established product, 10-15% for a growing brand still building organic rank, and 15-25% for a new product launch that's leaning on ads to generate early sales velocity and reviews.

TACoS vs. ACOS: why this number is different

TACoS divides total ad spend by total revenue — organic sales included — while ACOS (Advertising Cost of Sale) divides ad spend only by the sales that ad actually generated. A seller can run a campaign at a perfectly reasonable ACOS while still having an unhealthy TACoS, if most of their revenue depends on ads rather than organic ranking. TACoS answers a different, more important question: how dependent is this business on paid traffic to generate any sales at all?

What real accounts are seeing in 2026

Aggregated data from managed Amazon PPC accounts for the first half of 2026 puts the median TACoS at roughly 15%, alongside a median ACOS of 38% across the same accounts — a useful reminder that "good" ACOS and "good" TACoS aren't measuring the same thing and shouldn't be read as contradictory when they land far apart.

How TACoS varies by category

• Beauty and Supplements: typically 12-18%, reflecting intense competition and high customer acquisition costs in the category
• Electronics: typically 8-15%
• Home and Kitchen: typically 8-12%
• Tools and Home Improvement: typically 5-10%, among the lowest of any major category

A seller running meaningfully above their category's typical range isn't automatically doing something wrong — a new launch legitimately needs a higher TACoS to build velocity — but it's a signal worth checking against where the product actually sits in its lifecycle.

The direction matters more than the number itself

A declining TACoS alongside flat or growing revenue is the clearest sign of a healthy Amazon account, since it means organic sales are picking up a larger share of total revenue without total revenue shrinking. A seller obsessing over hitting a specific TACoS target in isolation, without tracking whether it's trending down as their catalog matures, is optimizing for the wrong signal.

What this means for budgeting ad spend

New launches should expect to run TACoS in the 15-25% range for the first few months and treat that as a deliberate investment in organic rank and review velocity, not a red flag. As a listing matures and organic sales pick up, TACoS should trend down toward the 5-10% range even if total ad spend in dollar terms stays flat or grows — if it doesn't, that's the signal the product isn't building sustainable organic demand.

Bottom Line

Budget for TACoS in the 15-25% range during a launch, expect it to settle into 5-10% once a product matures, and track the trend over time rather than fixating on hitting one static target — a falling TACoS with stable or growing revenue is the real marker of a healthy Amazon business.
