TACOS Calculator
Advertising spend as a share of all sales revenue.
Calculate
Use figures from the same reporting period and a consistent revenue basis.
Ad-attributed sales breakdown
Non-ad-attributed sales are a remainder estimate, not verified organic sales. Use matching attribution periods.
Result
TACOS cannot be calculated when total sales revenue is zero.
TACOS % = ad spend ÷ total sales revenue × 100.
Revenue ratios are not profit. Suitable performance depends on your costs, margins and attribution.
