What is TACoS?

TACoS stands for Total Advertising Cost of Sales.

Last updated: June 2026

TACoS — Total Advertising Cost of Sales: TACoS (Total Advertising Cost of Sales) = ad spend ÷ total revenue × 100. Unlike ACoS, it measures ad spend against all sales — organic included — so it shows whether your ads are growing the whole brand or just buying sales you would have made anyway.

In depth

TACoS is the strategic counterpart to ACoS. A falling TACoS over time means your ads are lifting organic rank and total sales, not just shifting demand into paid. A rising TACoS while ACoS looks fine often signals over-reliance on ads. TACoS is the truest single gauge of whether advertising is building a durable business.
