ROAS Calculator
Calculate return on ad spend. Enter revenue from a campaign and the ad spend to see ROAS as a ratio and percent, plus your break-even ROAS.
What ROAS measures
Return on ad spend is the revenue you earn for each dollar you put into ads. A ROAS of 3x means three dollars back for every dollar spent. It is the headline metric for paid campaigns because it answers the question owners care about most: are these ads making money.
Revenue ROAS is not profit
A 3x ROAS sounds great, but it ignores your costs. If your profit margin is 40 percent, you need a ROAS above 2.5x just to break even on the ad spend, because most of that revenue pays for the product. This tool calculates your break-even ROAS from your margin and tells you whether your campaign actually profits, not just whether it returns revenue.
How to use it
Enter the revenue a campaign produced and the ad spend behind it. Add your profit margin to see the break-even ROAS and a profit verdict. The tool returns ROAS as a multiple and a percent. For the cost side of your ads, use the CPM and CPC Calculator, and check the customer math with the CAC Calculator.
Frequently Asked Questions
How do you calculate ROAS?
Divide the revenue generated by a campaign by the ad spend for that campaign. A result of 3 means 3x revenue per dollar.
What is break-even ROAS?
It is one divided by your profit margin. Below it, ad revenue does not cover the product cost plus the ad spend.
Is a higher ROAS always better?
Usually, but a very high ROAS can mean you are underspending and leaving growth on the table. Balance ROAS with volume.
