Break-Even ROAS Calculator

Free tool · built by Lucas, Google Ads specialist for local businesses

Your break-even ROAS is simply 1 ÷ your profit margin — the return on ad spend you need just to cover costs. Enter your margin below to see it instantly. Add your current ROAS and you'll also see whether your ads are actually turning a profit.

Estimates only — based on the margin you enter. For true profit, make sure your margin already accounts for product/service costs (and ideally your management fee).

How this calculator works

Break-even ROAS is the one number that tells you what "good" means for your business — and it ignores generic benchmarks entirely. The formula is simple:

Break-even ROAS = 1 ÷ profit margin. At a 50% margin, that's 1 ÷ 0.5 = 2.0× — you need $2 back for every $1 spent to cover costs. Earn more than 2× and you profit; less and you lose money.

Add your current ROAS and the calculator compares it to your break-even point, then shows your profit (or loss) per $1 of ad spend — calculated as (your ROAS × margin) − 1.

What's a good ROAS for you?

"Good" is whatever clears your break-even, and that moves with your margin. High-margin businesses (most local services) are profitable at a far lower ROAS than low-margin retail:

How to beat your break-even ROAS

Once you know the target, two levers move your actual ROAS above it:

• Raise revenue per click — better conversion rate, higher close rate, more upsells and repeat business.
• Lower cost per click — tighter keywords, negative keywords and a better Quality Score.

If your ROAS is stuck below break-even, it's usually a tracking, targeting or landing-page problem — all fixable. Get in touch for an honest read.

Frequently asked questions

Break-even ROAS = 1 ÷ profit margin. At a 50% margin it's 2.0× — you need $2 of revenue per $1 of ad spend to cover costs. Above that is profit; below it is a loss.

Any ROAS comfortably above your break-even point. There's no universal number — at a 50% margin you profit above 2×, at 25% you need above 4×. Compare to your own break-even, not a benchmark.

At a 50% margin, yes (break-even is 2×). At a 25% margin, no — break-even is 4×, so 3× loses money. Run your margin through the calculator to be sure.

ROAS is what you're actually getting (revenue ÷ spend); break-even ROAS is what you need to cover costs (1 ÷ margin). Actual above break-even is profit; below is loss.
