What is ROAS (Return on Ad Spend)?
ROAS is the ratio of revenue generated from advertising to the amount spent on that advertising. It helps you understand how effectively your ad budget is driving revenue.
How to Calculate ROAS
Divide total revenue attributable to ads by the ad spend: ROAS = Revenue from Ads / Ad Spend.
ROAS Formula
ROAS (ratio) = Revenue / Ad Spend — displayed as 5.00x for a 5x ROAS. ROAS (%) = ROAS × 100 (e.g., 500%).
Real-World Example
If your ads generated $5,000 in revenue and you spent $1,000 on ads, your ROAS is 5.00x (500%). If your gross margin is 30%, your break-even ROAS is 1 / 0.30 = 3.33x.
Why ROAS Matters
ROAS helps prioritize campaigns, decide budget allocation, and quickly identify underperforming channels. Combined with margin metrics it also helps determine true profitability.
