Always up-to-date Facebook ad cost data from hundreds of millions of spend per month.
Data is calculated only from campaigns targeting audiences in the United States.

What does CPI mean on Facebook?

CPI stands for cost per install. CPI is calculated on Facebook by dividing your spend by mobile app installs.

For example, if your spend was $80 and you generated 22 mobile app installs for that $80, your CPI was $3.64 ($80/22=$3.64).

What is a good CPI for Facebook ads?

A good cost per mobile app install on Facebook is relative to your app, whether it’s paid or free, and if it’s free will be dependent on your app’s throughput of free users to paid users.

For paid apps, you should be aiming for a cost per app install that is equal to or less than your take of the revenue from one purchase.

For free apps, you should be aiming for a cost per app install that allows you to generate enough free users to get one paid user conversion with an average lifetime value equal to or above your cost.

Why is my Facebook CPI so high?

If you have a high cost per mobile app install, it could be due to several reasons not just with your Facebook ads, but also on your app store listing:

  • you might have high CPMs
  • the audience your targeting on Facebook is not quite the same as the people who are using your app
  • your app store listing doesn’t have exciting screenshot images

Think of all aspects of your funnel from the Facebook ad and its components to the conversion rate on the app store to identify weak links that could be increasing your cost per mobile app install.
