Return on ad spend (ROAS)

OmOmesta team·September 15, 2026

Definition

ROAS is attributed revenue divided by advertising spend.

ROAS is attributed revenue divided by advertising spend. For example, $1,000 of attributed revenue from $200 of ad spend is a 5× ROAS.

What it does not tell you

ROAS is not profit. It does not subtract product costs, staffing, platform fees or other operating expenses. Attribution windows and event matching can also change the reported value.

Compare consistently

Use the same dates, currency and attribution definitions. For lead-generation campaigns, review verified bookings or sales as well as the platform's reported conversions.
