Frequently asked questions
What is the difference between ROAS and ROI?
ROAS is revenue divided by ad spend. ROI is net profit after advertising and other expenses divided by those combined expenses.
Does CPA include product costs?
No. CPA is ad spend per acquisition. Product costs and fees are accounted for separately when calculating profit.
Why are some metrics shown as a dash?
When a formula would divide by zero, such as no clicks or no orders, the metric is undefined.
Are my numbers stored?
No. Calculations happen only in your browser. This calculator does not send your values to an API or store them.
Can I use this for Facebook Ads?
Yes. The same calculations apply to Google Ads, TikTok Ads, affiliate campaigns and other channels when you enter comparable data.
