How to Calculate CPI

The equation for CPI is:

CPI = Ad Spend ÷ Installs

What Does CPI Mean?

A CPI calculator is a tool used in mobile marketing and advertising to assess the efficiency of a mobile app installation campaign. It assists advertisers and app developers in calculating the cost of each download of their mobile app.

The following is a breakdown of the components:

• Whole Advertising Expenditure:
  This is the entire amount of money spent on promoting the mobile app. It covers advertising costs for numerous channels such as social network ads, in-app ads, display ads and so on.


• Number of Installs:
  The overall number of app installations as a result of the advertising campaign.
  
  Advertisers can analyze the effectiveness of their marketing efforts in recruiting new users by calculating the CPI. A lower CPI suggests that the cost of gaining each customer is comparatively low, resulting in a more cost-effective campaign. A higher CPI, on the other hand, may indicate that the advertising plan has to be modified.

Why is cost per install calculator important?

How do you calculate the cost per install?

The Cost Per Install (CPI) is calculated by dividing the total advertising cost by the number of app downloads. Here's how it works using the formula:

CPI = Total Advertising Spend​ / Number of Installs

Here is a step-by-step guide to help you to calculate the Cost Per Install (CPI):

1. Collect Data:
   Collect all the data needed for the calculations.


2. Enter the Data into the Formula:
   To calculate CPI, use the CPI formula and enter the values.


3. Perform the Calculations:
   Divide the total advertising spend by the number of installs.


4. Interpret the Findings
   The calculation's results indicate the Cost Per Install. This figure represents the cost of installing your mobile app as a result of the marketing efforts.

Example:
Suppose you spend $2,000 on advertising and receive 1000 installations during the campaign.
CPI = $2,000 / 1000 = $ 2
In this example, the cost per installation is $2.

FAQs:

Why does CPI concentrate on the number of installs over user engagement?

Answer: The cost-effectiveness of obtaining new installations is measured by the CPI. CPI must be supplemented by indicators such as retention rates and user engagement for a more holistic assessment of app success.

Is a low CPI an indicator of app success?

Answer: A low cost per install is a good indicator of effective user acquisition but success is determined by a variety of criteria including user quality and retention. By balancing CPI with other crucial metrics, you may get a more realistic picture of overall app performance.

How does CPI take into account the quality of new users?

Answer: CPI concentrates on the cost of each installation and may not evaluate user quality fundamentally. To evaluate user quality, CPI should be supplemented with measures such as in-app engagement, retention and user lifetime worth.

Can a high CPI for premium apps be justified?

Answer: Yes, for premium apps, a higher CPI may be justified if it results in the acquisition of customers with a higher lifetime value. When evaluating the cost-effectiveness of user acquisition, it is important to consider the app's unique value proposition and revenue possibilities.
