Frequently asked questions about the ROAS calculator
What is a ROAS calculator?
A ROAS calculator is a tool that measures how much a campaign sells for every unit of currency spent on advertising. This ROAS calculator also gives you the CPC, CTR, conversion rate, CPA, average order value and the minimum ROAS to avoid losing money.
How is ROAS calculated?
Divide the revenue generated by the campaign by the ad spend. If you spent CLP 500,000 and sold CLP 1,800,000, the ROAS is 3.6x: every CLP 1 spent brought back CLP 3.6 in sales.
What is a good ROAS?
It depends on your margin. The break-even ROAS is 1 ÷ margin: with a 35% margin, you need a ROAS of at least 2.86x; with a 20% margin, 5x. That is why the ROAS calculator asks for your business margin. If you don’t know it, work it out with our margin calculator.
What is the difference between CPA and CPC?
CPC is what you pay for each click on your ad: spend ÷ clicks. CPA is what you pay for each sale or conversion: spend ÷ conversions. A campaign can have a low CPC and a high CPA if clicks don’t turn into purchases.
Where do I get my campaign data?
Spend, impressions and clicks appear in your ad platform’s dashboard, such as Google Ads or Meta. Sales and revenue come from your store or Google Analytics. To attribute each sale to its campaign correctly, tag your links with our UTM link builder.
Is the ROAS calculator free?
Yes. It is free, requires no sign-up and runs in your browser: data is not sent to any server. The ROI it shows compares revenue with ad spend, without subtracting product costs. Find more guides in the Marketing & consumer section.
