What Is a Good ROAS? Benchmarks by Margin Level
There is no universal good ROAS — only a ROAS that is profitable for your margin. A 3× ROAS sounds strong until you realize 25% margin businesses need 4× just to break even.
Why generic ROAS targets fail
Agencies and blog posts often cite 3× or 4× ROAS as a minimum. Those numbers assume a specific margin profile. At 60% margin, break-even ROAS is about 1.67× — holding out for 4× leaves scale on the table. At 25% margin, 3× still loses money.
- 50% margin → break-even ROAS ≈ 2.0×
- 40% margin → break-even ROAS ≈ 2.5×
- 25% margin → break-even ROAS ≈ 4.0×
Good ROAS vs break-even ROAS
Break-even ROAS is your floor. Good ROAS is anything above it — how far above depends on your profit goals and competitive pressure. A practical target is break-even ROAS plus 20–30% headroom for ecommerce scaling.

Platform ROAS is not profit ROAS
Google Ads, Meta, and Shopify report revenue ROAS. They do not subtract COGS, shipping, or payment fees. Always translate platform ROAS into contribution ROAS before comparing to benchmarks.
Frequently asked questions
- What is a good ROAS for ecommerce?
- It depends on gross margin. At 50% margin, break-even is about 2× and good might be 2.5× or higher. Calculate your specific floor rather than using industry averages.
- Is 4× ROAS good?
- Only if your margin is around 25% or higher with minimal fixed costs. At 50% margin, 4× is well above break-even and may be unnecessarily conservative for scaling.
- What ROAS should I target in Google Ads?
- Set target ROAS at or above your break-even ROAS from margin and AOV. Use our break-even calculator, then add profit headroom if needed.
