What is CPI?

CPI (Cost Per Install) is the standard metric for mobile user acquisition campaigns. It tells you how much you spend for each user who installs your app — directly linking media spend to app growth.

Worked Example

A mobile app campaign spends $25,000 and drives 5,000 app installs. CPI = $25,000 ÷ 5,000 = $5.00 per install. Gaming apps often target $1–3 CPI; fintech apps may accept $20+ CPI if LTV is high.
