What is ROAS?
ROAS (Return on Ad Spend) is a marketing metric that measures the revenue generated for every dollar spent on advertising. It is calculated by dividing total revenue from ads by total ad spend. A ROAS of 4x means you earned $4 in revenue for every $1 spent on ads.
How to Calculate ROAS
The formula is simple: ROAS = Revenue ÷ Ad Spend. For example, if you spent $500 on a campaign and generated $2,000 in revenue from it, your ROAS would be $2,000 ÷ $500 = 4x. That means every dollar spent returned four dollars in revenue.
What is a Good ROAS?
Google Ads campaigns typically average a 2-4x ROAS. Meta Ads (Facebook and Instagram) campaigns see similar ranges of 2-4x. eCommerce businesses often target 4x or higher to stay comfortably profitable. The "good" ROAS for your business depends heavily on your profit margin — use the break-even calculator above to find your specific target.
ROAS vs ROI — What is the Difference?
ROAS measures revenue per ad dollar — it ignores costs like product, shipping, and overhead. ROI measures profit per total investment — it includes all costs. You can have a 4x ROAS but negative ROI if your margins are thin, which is why tracking both metrics together gives a more complete financial picture.
How to Improve Your ROAS
- Improve audience targeting to reach more qualified buyers.
- Test multiple ad creatives and pause underperforming variations.
- Optimize your landing pages to convert more visitors.
- Pause campaigns or ad sets that consistently underperform.
