TACoS

Total Advertising Cost of Sale

TACoS (Total Advertising Cost of Sale) measures total ad spend as a percentage of total receita (both organic and ad-attributed). Unlike ACOS which only considers ad-driven sales, TACoS provides a holistic view of advertising efficiency relative to overall business performance.

Why TACoS Matters for Amazon Sellers

TACoS is a superior metric for measuring advertising effectiveness over time because it accounts for the organic sales lift that PPC generates. Decreasing TACoS with stable or increasing ACOS indicates growing organic market share — the ultimate goal.

Month 1: $5,000 ad spend, $10,000 total sales = 50% TACoS. Month 6: $5,000 ad spend, $25,000 total sales = 20% TACoS. Same ad spend, but organic sales tripled — advertising is building the business.
