What Is the CPI Equation?

CPI, or Cost Per Install, is one of the most crucial metrics in mobile app marketing. It tells you how much you're paying for each user who installs your app via a paid campaign.

CPI Formula:

CPI = Total Ad Spend ÷ Number of Installs

This equation is the foundation for any campaign budget analysis, helping marketers calculate ROI and fine-tune acquisition strategy.

Why the CPI Equation Matters

• Helps determine campaign profitability

• Indicates funnel efficiency

• Guides budget allocation across channels

• Impacts long-term LTV-to-CAC modeling

Factors That Increase Your CPI

• Poor ad creative or call-to-action

• Low install conversion rate (CVR)

• Platform ad bans or review blocks

• Bot traffic or invalid impressions
