What is CPI?

CPI stands for "Cost Per Install." It measures the cost an advertiser pays for each instance of a user installing a mobile application after clicking on an advertisement. CPI is a key metric for mobile app developers and marketers to assess the efficiency of their user acquisition campaigns and drive app downloads.

How to measure CPI?

CPI is calculated by dividing the total advertising spend by the number of app installs.

CPI = Total Advertising Spend / Number of App Installs

Example: If an ad campaign costs $2,000 and generates 500 app installs, the CPI would be $4.
