What is a good ROAS?

A good ROAS (return on ad spend) is simply any return that clears your break-even point, and that point is set by your profit margin, not by an industry average. The formula is straightforward: break-even ROAS equals 1 divided by your contribution margin. If you keep 30 cents of profit on every euro of revenue, your break-even ROAS is 1 divided by 0.30, which is about 3.3x. Anything above that earns money, anything below loses it. So before you ask whether 4x is good, you need to know your own margin. ROAS is explained in more depth in our glossary entry on ROAS.

This is why blanket benchmarks like target 4x are misleading. A digital product or SaaS business with an 80 to 90 percent margin can be wildly profitable at a 1.5 to 2x ROAS, because almost every euro of revenue is profit. A high-end fashion brand at 60 to 70 percent margin might target 2 to 3x. A typical ecommerce retailer keeping 20 to 30 percent after product cost, shipping, and fees needs roughly 4 to 6x just to break even on the first order. A low-margin reseller can need 8x or more. The same ROAS number can be excellent for one business and ruinous for another.

Business model changes the target even more than industry. Lead-gen companies often do not measure ROAS at all because there is no immediate revenue per click; they track cost per qualified lead and close rate instead. Subscription and high-repeat businesses can run a low or even negative first-order ROAS on purpose, because lifetime value pays back the acquisition cost over months. If you only judge those models on first-purchase ROAS, you will starve your best growth campaigns. Decide whether you are optimising for first-order return or lifetime return before you set a number.

As rough orientation only, here is what we commonly see as healthy steady-state targets: established ecommerce brands aim for 3 to 5x blended, high-margin or premium products can be happy at 2 to 3x, prospecting and top-of-funnel campaigns often run lower (1.5 to 3x) while retargeting and brand search run much higher (6 to 15x), and digital or subscription products optimise to a payback period rather than a single ROAS. Treat these as starting points to pressure-test against your own margin, not as goals to copy.

Be careful which ROAS you are reading. Platform-reported ROAS inside Google or Meta is inflated by attribution: it counts conversions the channel claims credit for, often double-counting across platforms and including sales that would have happened anyway. Blended ROAS (total revenue divided by total ad spend across all channels) is harder to game and closer to the truth. The most useful version is marginal or incremental ROAS: the extra revenue you get from the last euro spent, which tells you whether scaling up still pays.

So what is a good ROAS for you? Calculate your break-even from your real contribution margin, add the profit cushion you want on top, and that is your floor. Then decide whether you are managing to first-order or lifetime value. If your reported ROAS looks great but the bank account does not agree, the problem is usually attribution or margin assumptions, and that is exactly what we untangle in an audit.
