ROAS Calculator
ROAS is attributed revenue divided by ad spend. Revenue of 4,500 from spend of 1,500 gives 3× ROAS, equivalent to 300%.
Formula & method
ROAS = attributed revenue ÷ ad spend; percentage = ROAS × 100.Worked example
| Input | Value |
|---|---|
| Attributed revenue | 4,500 ¤ |
| Advertising spend | 1,500 ¤ |
| Result | Value |
|---|---|
| Return on ad spend | 3 × |
| ROAS as a percentage | 300 % |
| Revenue remaining after ad spend | 3,000 ¤ |
Compare scenarios
The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.
| Compare scenarios | Attributed revenue ¤ | Return on ad spend | ROAS as a percentage | Revenue remaining after ad spend |
|---|---|---|---|---|
| −20% | 3,600 | 2.4 × | 240 % | 2,100 ¤ |
| Example | 4,500 | 3 × | 300 % | 3,000 ¤ |
| +20% | 5,400 | 3.6 × | 360 % | 3,900 ¤ |
Assumptions & limits
Revenue remaining after ads is not net profit. Product costs, fulfilment, payment fees, refunds and overhead still need accounting. Use matching attribution windows and one currency.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.
Use the same currency and reporting period for every monetary input. This tool does not fetch prices, exchange rates or account data.

Break-Even ROAS Calculator
Break-even ROAS is one divided by the contribution-margin fraction. A 25% contribution margin implies 4× ROAS, or 400%, before fixed costs and a profit target.
Campaign ROI Calculator
Campaign ROI equals revenue minus total included costs, divided by those costs, multiplied by 100. Include costs beyond media spend to make the comparison meaningful.
Gross Margin Calculator
Gross margin is revenue minus included cost of goods, divided by revenue, multiplied by 100. Revenue of 1,000 and cost of 650 gives a gross profit of 350 and margin of 35%.
CPM Calculator
CPM equals advertising spend divided by impressions, multiplied by 1,000. A spend of 1,200 for 400,000 impressions gives a CPM of 3 in the same currency.
