Cost Per Install


Cost Per Install calculates the average cost incurred to acquire a new user who installs the app, often through advertising. It's a key metric for assessing the efficiency and ROI of app marketing campaigns. A lower cost is generally desirable, indicating cost-effective user acquisition.


Total Ad Spend / Number of Installs


If $5,000 spent on ads results in 1,000 app installs, the CPI is $5,000 / 1,000 = $5 per install.
