It depends on margin. At a 25% gross margin, a 4x return exactly breaks even, while at 60% it is very profitable. Calculate break even as 1 divided by your gross margin and compare.

What is the difference between ROAS and ROI?

ROAS divides revenue by ad spend. ROI divides profit by total cost. ROAS ignores product and overhead costs, so it can look healthy while ROI is negative.

Should ROAS be the only metric I track?

No. Track blended ROAS, cost per acquisition, contribution margin and repeat purchase rate alongside it. A single platform ROAS figure can mislead because of attribution overlap.

How do I raise my ROAS?

Improve the conversion rate of the landing page, raise average order value with bundles or higher priced options, refresh creative, and remove spend on audiences or placements that do not buy.

ROAS Calculator: What Is a Good ROAS and How to Find Your Break Even

Ask ten marketers what a good ROAS is and you will hear ten numbers. The only number that matters is the one your own margins produce. Here is how to calculate it.

What ROAS measures

Return on ad spend is revenue attributed to ads divided by the amount spent on them. If you spend $1,000 and the ads generate $4,000 in sales, ROAS is 4, often written 4x or 400%.

It is useful because it is simple. It is dangerous for the same reason: revenue is not profit. A 4x return can lose money on a thin margin and a 2x return can be very profitable on a high one. That is why a generic "good ROAS" number is close to meaningless.

Break even ROAS is the return at which ads exactly pay for themselves. Target ROAS adds the profit you want per order. If either shows n/a, the product loses money before any advertising and the offer needs fixing first.

The break even ROAS formula

Break even ROAS is 1 divided by your gross margin, where gross margin is the share of the sale price left after product cost, shipping and payment fees but before ad spend.

Gross margin	Break even ROAS
20%	5.00
30%	3.33
40%	2.50
50%	2.00
60%	1.67
70%	1.43

Calculated from the formula 1 divided by margin.

A worked example. A product sells for $50. Product cost, shipping and fees come to $30, so gross margin is $20, or 40%. Break even ROAS is 2.5. At that return, the $50 sale pays for the $20 of advertising and leaves exactly zero profit on the first order.

Target ROAS sits above break even

Breaking even is not the goal. A target ROAS must also cover overheads, team costs and the profit you want. A simple way to set it: decide the contribution margin you want per order after ads, then solve backwards.

Using the same $50 product with a $20 margin, suppose you want $5 of profit per order after ad cost. That leaves $15 for advertising, so you can pay up to $15 to win a customer. Revenue per order divided by that cost is 50 / 15, a target ROAS of about 3.3.

Repeat customers change the picture. If a buyer typically orders three times, you can accept a lower first order ROAS, even one at or below break even, because lifetime margin pays back the acquisition. That only holds if you have real repeat purchase data, so use your own numbers rather than hoping.

Why platform ROAS and real ROAS differ

The ROAS in Meta or Google reports is attributed ROAS, and several things distort it:

Attribution windows. Counting purchases up to seven days after a click, or one day after a view, credits ads for sales that might have happened anyway
Branded search. People searching your company name were already coming. Including those conversions flatters campaign results
Duplicate credit. When Meta, Google and email each claim the same sale, reported revenue adds up to more than you actually earned

The check is blended ROAS: total revenue divided by total ad spend across all channels. It is harder to fool. If platform reports say 4x but blended is 2x, believe the blended number and investigate.

Setting budgets from the numbers

With a break even and a target, budget decisions get simpler:

If a campaign sits above target ROAS and has room to grow, raise its budget gradually, roughly 20% at a time, so the algorithm keeps its learning
If it sits between break even and target, hold budget and work on creative or the landing page
If it stays below break even after a fair test, cut it. Fair means enough spend to see a result, roughly two to three times your target cost per purchase

Lead generation uses a different yardstick

If you sell services rather than products, ROAS is often replaced by cost per lead and cost per acquisition. The logic is the same. Work out what a customer is worth, the share of leads that close, and then the most you can pay per lead. Our guide to how to generate leads covers the funnel side, and our lead generation services page shows how we run it.
