What ROAS do you actually need to make money?
Ads Manager says 3x and the bank account disagrees. Break-even ROAS is one division away, and it is different for every store because it depends on your margin, not on anyone's benchmark.
The formula
Break-even ROAS equals 1 divided by your contribution margin ratio. At 50% margin you break even at 2.0x. At 25% margin you need 4.0x just to not lose money.
That is why asking whether 4x is good is meaningless without your cost structure. For a store keeping 55 cents per revenue dollar it is comfortable. For one keeping 20 cents it is a slow leak. Compute yours in seconds with the free break-even ROAS calculator.
Break-even is the floor, not the target
At exactly break-even, you paid the ad platform to process orders at zero profit. Your working target should sit 1.5 to 3 times above break-even, to cover overhead, your own pay and reinvestment.
For context: the average Facebook ads ROAS in recent benchmarks is around 2.2x, apparel and beauty run 3.5 to 4.2x, and Shopify itself calls 4x a solid starting point. Use these as sanity checks, never as targets.
Why the number in Ads Manager is lying to you
Three distortions to correct before trusting any ROAS number:
- Platform inflation. Meta overstates ROAS by roughly 28% on average, and in-platform attribution across channels runs 30 to 40% hot versus reality.
- Blended flattery. Blended ROAS includes email, organic and returning customers. It can look stable while new-customer acquisition quietly deteriorates. Watch new-customer ROAS separately.
- Ignored costs. Discounts and returns lower the real revenue behind each conversion after the platform has claimed credit.
The honest measuring stick
MER, total revenue divided by total marketing spend, is the sanity check that cannot be gamed by attribution. And underneath everything sits the margin math from real profit on Shopify: improving margin lowers the ROAS you need, which is often easier than raising the ROAS you get.

Common questions
Is 1x ROAS break-even?
No. At 1x you recovered revenue, not costs. Real break-even for most stores sits between 2x and 3x depending on contribution margin.
What is a good ROAS for Facebook ads?
The benchmark average is around 2.2x and strong categories run 3.5 to 4.2x, but the only number that matters is your own break-even, which is 1 divided by your contribution margin.
Why is my ROAS good but I am still losing money?
Usually a mix of platform over-attribution, blended ROAS hiding weak new-customer performance, and discounts or returns shrinking the real revenue per conversion.
