Paste one row per campaign - ad spend and revenue. A label column is optional. Commas or tabs both work.
The ROAS formula
This ROAS calculator shows return on ad spend as a ratio and in plain dollars. The formula is ROAS = revenue / ad spend. Spend 1,000 and make 4,000 and your ROAS is 4.0, usually written 4:1 or 400 percent, which is 4 dollars back for every 1 dollar in. The data shows people search for ROAS in both formats, so the calculator gives you the ratio, the percentage, and the revenue-per-dollar at once. Switch to the Break-even tab to find the minimum ROAS you need just to cover costs.
ROAS versus ROI
ROAS and ROI are easy to confuse. ROAS compares revenue to ad spend only, so it is quick and useful for judging a campaign at a glance. ROI compares profit to total cost, so it tells you whether you actually made money after the product, shipping and overheads. A campaign can post a healthy-looking 4x ROAS and still lose money if the margins are thin. That is why break-even matters.
Break-even ROAS and why margin is everything
Break-even ROAS is simply 1 / profit margin. At a 25 percent margin you need a 4.0x ROAS just to break even; at a 50 percent margin you break even at 2.0x. This is the number that turns a benchmark into a decision. A 3x ROAS is excellent for a high-margin digital product and a loss-maker for a thin-margin reseller. Always compare your ROAS to your own break-even, not to a generic target.
What is a good ROAS?
The common rule of thumb is 2:1 to 4:1, but 2026 data tells a soberer story: the average ecommerce ROAS is around 2.9x and the median is closer to 2.0x, meaning half of stores make under two dollars per ad dollar. It varies enormously by platform and industry:
| Context (2026) | Typical ROAS |
|---|---|
| Overall ecommerce, all channels | ~2.9x average, ~2.0x median |
| Google Search | 2:1 - 4:1 |
| Google Shopping | 3:1 - 5:1 |
| Meta (Facebook / Instagram) | ~1.9x - 2.5x blended (retargeting / Advantage+ 3.5x - 4.5x) |
| "Good" rule of thumb | 3:1 - 4:1, judged against your margin |
| By industry range | roughly 1.5x - 7x depending on industry |

Levers to improve your ROAS
ROAS is a ratio, so you move it by lifting the top or trimming the bottom. On the revenue side, raising average order value stretches every ad dollar further, so an order-value bump often does more for ROAS than chasing cheaper clicks. Improving the landing page conversion rate turns the same traffic into more sales, which flows straight through to ROAS. On the cost side, cutting wasted spend, adding negative keywords, pausing weak placements, and concentrating budget on high-intent search usually beats broad, cold reach. And because break-even is set by your margin, anything that widens your margin lowers the ROAS you need in the first place. Our average order value and conversion rate calculators cover the two revenue levers directly.
Frequently asked questions
What is a good ROAS?
A rule of thumb is 2:1 to 4:1, but it depends on your margin and break-even. High-margin businesses can profit at 2x; thin-margin ones may need 5x or more.
How do you calculate ROAS?
Divide revenue by ad spend. Spend 1,000, make 4,000, and your ROAS is 4.0, written 4:1 or 400 percent.
What is break-even ROAS?
It is 1 divided by your profit margin. At 25 percent margin you break even at 4.0x; at 50 percent margin, 2.0x. Below that, the ad loses money.
ROAS or ROI, which should I use?
ROAS is faster for judging a campaign; ROI is the truer measure of profit because it counts all your costs, not just ad spend.
Why is my ROAS good but I am not profitable?
Because ROAS ignores product cost and overheads. If your ROAS is below your break-even ROAS for your margin, you lose money despite a healthy-looking ratio.
