CPI Calculator

How to use the CPI calculator

To calculate CPI, enter the total amount that you spent on ads and the number of installs that you received for your application. The calculator will instantly calculate the CPI, allowing you to understand the cost-effectiveness of your marketing efforts.

CPI formula

CPI=Total Ad Spend​/Number of Installs

Understanding the CPI result

The ideal CPI will vary depending on your location, type of app, and budget. However,

• A low CPI indicates that the marketing campaign for your app is cost-effective and that you are getting more installs at a relatively lower cost.
• A high CPI suggests a higher cost per install. This indicates that you need to optimize your marketing strategy in terms of content, target audience, advertising channels, etc.

When to calculate CPI

CPI should be calculated regularly to assess the performance of your app marketing campaigns. Some key situations where you should calculate CPI include:

• After launching a new app or a major update to track initial marketing effectiveness
• While running paid advertising campaigns focused on driving app installs
• To evaluate the performance of different ad networks, platforms, or creative formats
• During financial reviews to determine the return on investment (ROI) of your app marketing spend
• To compare against industry benchmarks or competitor CPI rates

How to calculate CPI with example

Imagine that you spent $10,000 on a marketing campaign that resulted in 5,000 app installs. You can calculate your CPI as follows:

CPI = Total Ad Spend​/Number of Installs

CPI =10,000/5,000 = 2

In this example, your CPI is $2.00, meaning you spent $2.00 on average to acquire each app install.

You can improve your CPI by using the following strategies:
