What Is a Good ROAS?
There is no universal good ROAS. The only meaningful benchmark is your own break-even ROAS, which is 1 divided by your gross margin. At a 50% margin you break even at 2.0, so anything above 2.0 is profitable; at a 25% margin you break even at 4.0, and a ROAS of 3.0 loses money. Published benchmarks like 4:1 are meaningless without the margin they assume, and for businesses with repeat purchase or long sales cycles, ROAS on first purchase understates performance considerably.
Why the question has no general answer
ROAS is revenue divided by ad spend. Spend 1,000, generate 4,000 in revenue, and your ROAS is 4.0. What that figure means for your business depends entirely on what it costs you to deliver that 4,000 of revenue — which is why a number quoted without a margin attached tells you nothing.
Two businesses can both report a ROAS of 3.0. The one with a 70% gross margin is comfortably profitable. The one with a 25% margin is losing money on every sale. Same metric, opposite conclusions.
Calculate your break-even ROAS first
Break-even ROAS = 1 / gross margin. That single line replaces every borrowed benchmark.
| Gross margin | Break-even ROAS | ROAS of 3.0 means |
|---|---|---|
| 20% | 5.0 | Losing money |
| 25% | 4.0 | Losing money |
| 33% | 3.0 | Exactly break-even |
| 50% | 2.0 | Profitable |
| 70% | 1.43 | Comfortably profitable |
Read the third column carefully. A ROAS of 3.0 — the sort of figure often reported as a success — is a loss for anything under a third margin. This is the single most common way advertising is misjudged.
Target ROAS is not break-even ROAS
Break-even tells you where you stop losing money. It does not tell you what to aim for, because a campaign running exactly at break-even contributes nothing to overhead or profit.
Your target should sit above break-even by enough to cover the fixed costs the campaign should help carry and leave the profit you want. There is no formula for that margin of safety — it is a business decision about how much of your growth you are willing to reinvest.
When ROAS is the wrong metric
ROAS measures revenue from a purchase against the spend that produced it. That framing breaks in three common situations.
- Repeat purchase. If customers buy repeatedly, first-purchase ROAS understates the return badly. A ROAS of 1.5 on first order can be excellent if the customer orders four more times.
- Long or consultative sales cycles. Where the conversion is an enquiry rather than a sale, there is no revenue to divide by at the point of measurement. Cost per acquisition against customer lifetime value is the more honest pairing.
- Mixed channels. When several channels influence one purchase, attribution decides which one gets credited. Channel ROAS figures rarely reconcile to the blended reality.
For service businesses in particular, ROAS is usually the wrong first metric. What matters is what an enquiry costs, what proportion of enquiries become customers, and what a customer is worth — which is the territory of customer acquisition cost rather than ROAS.
Work it out on your own figures
The ROAS calculator on this site takes spend and revenue and returns the ratio; the profit margin calculator gives you the margin that turns that ratio into a verdict. Running both takes a minute and replaces every borrowed benchmark with a number that is actually about your business.
Frequently asked questions
- What is a good ROAS?
- There is no universal figure. The meaningful benchmark is your break-even ROAS, calculated as 1 divided by your gross margin. At a 50% margin that is 2.0; at a 25% margin it is 4.0. Anything above your break-even is profitable, anything below it is not.
- How do you calculate break-even ROAS?
- Divide 1 by your gross margin expressed as a decimal. A 40% gross margin gives 1 / 0.4 = 2.5, so you need a ROAS above 2.5 to make money. Use gross margin after cost of goods and direct delivery costs, not net margin.
- Is a ROAS of 4 good?
- It depends entirely on margin. At a 50% gross margin, a ROAS of 4 is strongly profitable. At a 20% margin, break-even is 5.0, so a ROAS of 4 is a loss. The figure cannot be judged without the margin.
- What is the difference between ROAS and ROI?
- ROAS compares revenue to advertising spend only. ROI compares profit to total investment, including costs beyond advertising. ROAS is the narrower operational metric; ROI is the business one, and they can point in different directions.
