Free ROAS Calculator
Calculate your Return on Ad Spend in seconds, find the break-even ROAS your profit margin actually requires, and see how your number compares to platform benchmarks.
Above break-even: this campaign is genuinely profitable at your margin.
The ROAS formula
ROAS = Revenue attributed to ads ÷ Ad spend. Spend $2,000 and generate $7,000 of tracked revenue: ROAS = 3.5. Expressed as a percentage that is 350%. Unlike ROI, ROAS ignores your costs of goods — which is exactly why a “good looking” ROAS can still lose money.
Break-even ROAS: the number that actually matters
Break-even ROAS = 1 ÷ gross margin. A store with a 40% margin needs ROAS 2.5 just to not lose money; at a 25% margin the bar rises to 4.0. Judge every campaign against yourbreak-even, not against someone else’s screenshot.
| Gross margin | Break-even ROAS |
|---|---|
| 20% | 5.00 |
| 30% | 3.33 |
| 40% | 2.50 |
| 50% | 2.00 |
| 60% | 1.67 |
Why your ROAS differs across Meta, Google, TikTok and Snapchat
Every platform grades its own homework: different attribution windows (7-day click on Meta, up to 28-day click on Snapchat), and each claims the same order for itself. Add the platform-reported numbers together and you will count many sales twice. To compare channels fairly you need one normalized attribution window across all of them — Reportatk does exactly that for agencies and stores in the Gulf, in Arabic and English.
Frequently asked questions
What is ROAS?
ROAS (Return on Ad Spend) measures how much revenue you generate for every unit of currency spent on advertising. ROAS = attributed revenue divided by ad spend. A ROAS of 4 means every $1 of ads returned $4 in revenue.
What is a good ROAS?
It depends entirely on your profit margin. A business with 50% gross margin breaks even at ROAS 2.0, while a 20% margin business needs ROAS 5.0 just to break even. Ecommerce campaigns commonly target ROAS 3-5; brand campaigns run lower by design.
How do I calculate break-even ROAS?
Break-even ROAS = 1 divided by your gross profit margin. With a 40% margin: 1 / 0.40 = 2.5. Below that number a campaign loses money even if the ROAS looks healthy.
Why is my ROAS different in each ad platform?
Each platform attributes conversions with its own window (for example 7-day click on Meta vs 28-day click on Snapchat) and each claims the same sale for itself. Summing platform-reported revenue double-counts orders. Comparing platforms fairly requires normalizing attribution windows across all of them.
