How to Calculate Return on Ad Spend (ROAS)

Why Return on Ad Spend (ROAS) Matters

ROAS is the most direct measure of advertising efficiency and determines whether your campaigns are profitable after accounting for costs. Tracking ROAS by platform, campaign, and creative helps you allocate budget to what actually works. Without monitoring ROAS, you risk scaling campaigns that look busy but lose money on every sale.
