What is the CPA Calculator?
Cost per acquisition, or CPA, is the average amount you spend to get one conversion, such as a sale, sign-up or booking. Divide spend by conversions. It is only useful against what a conversion is worth to you, so compare it with your margin per sale.
How it works
CPA = ad spend / conversions. Conversions per ₹10,000 = conversions / spend x 10,000. If there are no conversions or no spend, the matching result shows zero. Define what counts as a conversion and keep it consistent across campaigns.
How to use it
- Enter the ad spend for the campaign.
- Enter the number of conversions you counted.
- Read the cost per acquisition.
- Compare it with the profit you make on each conversion.
CPA Calculator — FAQ
What is a conversion?
It is the action you want, such as a purchase, enquiry, call or form submission. Choose one definition and count it the same way every time.
How is CPA different from CPL?
CPA counts any chosen conversion, often a sale. CPL counts leads, which are earlier in the journey and usually cheaper.
Should I include agency fees in spend?
Include them if you want the true cost of acquisition. Use platform spend only if you want to judge the media itself.
