What is Blended ROAS?

Blended ROAS (also called total ROAS or account-level ROAS) measures total business revenue against total ad spend across all channels. Unlike channel-specific ROAS, it gives you the full picture of how advertising is driving overall revenue.

Why It Matters

In a world of imperfect attribution, channel-level ROAS can be misleading. Meta might take credit for a sale that Google initiated, and vice versa. Blended ROAS cuts through attribution noise and answers the fundamental question: “Are our ads driving profitable growth?”

How to Calculate It

Blended ROAS = Total Revenue ÷ Total Ad Spend (All Channels)

Benchmarks

The right target depends on your contribution margin, but as a general guide:
