CPI
Cost Per Install
The average cost to drive one app install through paid advertising. CPI = Total Spend ÷ Total Installs. It is the primary efficiency metric for mobile user acquisition campaigns and varies significantly by platform and category.
How CPI works in practice
Average CPI varies dramatically by app category — gaming averages £0.50–£1.50 while fintech and crypto apps commonly see £5–£25+ due to high LTV justifying competitive bidding. The most meaningful CPI benchmark is not the industry average but the maximum CPI sustainable given your LTV:CAC targets. CPI can be reduced by improving App Store conversion rate through ASO (better screenshots, icon, ratings), targeting higher-intent keywords with lower competition, and improving post-click landing pages for web-to-app flows. Downstream events — registration, deposit, first transaction — should always be tracked alongside CPI; a lower-CPI campaign that produces low-quality users with poor downstream engagement is worse than a higher-CPI campaign with strong LTV.
