What Is ROAS and How Do You Calculate It?
ROAS tells you how much revenue every rupee of ad spend brings back. Learn the formula, break-even ROAS and how to improve it.
ROAS (return on ad spend) measures how much revenue you earn for every unit of money spent on ads. ROAS = Revenue from ads / Ad spend. A ROAS of 4 means ₹4 in revenue for every ₹1 spent. Whether that is profitable depends on your margins, which is why you also need break-even ROAS.
Key takeaways
- ROAS is a revenue ratio, not profit.
- Break-even ROAS = 1 / profit margin.
- ROI includes all costs; ROAS includes only ad spend.
- Compare ROAS by campaign, audience and creative to decide where to scale.
The ROAS formula
ROAS = Revenue attributed to ads / Ad spend
Illustrative example: you spend ₹50,000 and the campaign brings ₹2,00,000 in revenue. ROAS = 2,00,000 / 50,000 = 4 (often written 4x or 400%).
Break-even ROAS
Break-even ROAS = 1 / Gross profit margin
Illustrative example: with a 40% margin, break-even ROAS is 1 / 0.40 = 2.5. Below 2.5 you lose money on each sale; above it you profit (before other costs).
ROAS vs ROI
| ROAS | ROI | |
|---|---|---|
| Measures | Revenue per ad spend | Profit per total investment |
| Includes | Ad spend only | All costs (product, staff, tools, ads) |
| Use | Campaign decisions | Business decisions |
What is a good ROAS?
There is no universal good ROAS. It depends on margins, customer lifetime value and goals. A low-margin product needs a higher ROAS; a subscription with strong retention can accept a lower first-purchase ROAS.
How to improve ROAS
- Improve landing page conversion rate.
- Narrow targeting to high-intent audiences.
- Refresh creatives that are fatiguing.
- Raise average order value with bundles and upsells.
- Cut placements and keywords that spend without converting.
- Fix tracking so revenue is attributed correctly. See Cookieless Tracking.
Conclusion
ROAS is the quickest health check for paid campaigns, but always compare it with break-even ROAS and true profit. Learn more metrics in Affiliate KPIs Explained.
