What Is a Good ROAS?

There is no universal good ROAS

A ROAS that is healthy for a high-margin software business can be ruinous for a low-margin retailer, because the costs the two businesses must cover are different. Any single “good ROAS” number ignores margin, fees, returns and lifetime value, so it cannot tell you whether your advertising is actually making money. The right question is not “what is a good ROAS” but “what ROAS does my business need”.

What sets your ROAS threshold

• Gross margin. Lower margins need a higher ROAS to break even — a 25% margin needs 4x, a 50% margin needs 2x.
• Variable costs. Shipping, payment processing, packaging and commissions reduce the contribution available for ad spend.
• Customer lifetime value. Customers who return can justify a lower first-order ROAS because later orders add contribution.
• Repeat purchase rate. A subscription or refill business can pay more to acquire a customer than a one-time purchase business.
• Refunds and returns. Refunded orders still cost money to process and reduce effective contribution.
• Shipping and payment fees. These scale with every order and are easy to overlook in a margin figure.
• Business overhead. Fixed costs that advertising must help cover set a floor above break-even.
• Growth objectives. Scaling aggressively may accept a lower near-term ROAS to buy volume and market share.

Break-even ROAS is the real benchmark

Break-even ROAS is the minimum ROAS your cost structure can sustain before advertising becomes a loss. It is built from your own numbers, so it is the only benchmark that actually applies to your business. Calculate it with the Break-Even ROAS Calculator and compare it to the ROAS your campaign is producing with the ROAS Calculator.

Higher ROAS is not always better

A higher ROAS is not automatically better if it comes at the cost of scale. Suppose a campaign at 4x ROAS spends $10,000 and produces $40,000 of revenue, and the break-even ROAS is 2.5x. Capping spend to push ROAS to 6x might reduce spend to $2,000 and revenue to $12,000. The ROAS looks better, but total contribution falls, because fewer orders means less money left after costs. A ROAS above break-even is only useful if the volume behind it is meaningful.

Using target ROAS to plan a profit goal

Once you know your break-even ROAS, target ROAS tells you how much higher you need to go to keep a chosen profit margin after advertising. If break-even is 2.5x and you want a 10% profit margin, target ROAS rises to about 3.33x — the gap is what the profit goal costs. Plan it with the Target ROAS Calculator.

How to evaluate your ROAS

1. Calculate your break-even ROAS from your unit economics.
2. Compare your actual campaign ROAS to that floor, not to a benchmark.
3. Set a target ROAS for the profit margin you want to keep.
4. Check that the volume behind the ROAS is worth the spend.
5. If customers repeat, weigh first-order ROAS against customer lifetime value using the Customer Lifetime Value Calculator.
