Cost Per Install (CPI)

The Cost Per Install (CPI) is one of the most useful KPIs for assessing the effectiveness of mobile app promotion. Mobile developers, publishers, and marketers all rely on this metric. But what does CPI stand for, and how can you calculate and use it effectively?

What Is the Cost Per Install (CPI)?

The Cost Per App Install is a metric that shows the performance of your marketing campaign. It's one of the most transparent and easy-to-understand KPIs for mobile developers. The Cost Per Install formula is simple: just divide your ad spend by the total number of app installs for the same period.

In essence, CPI tells you how much money you need to spend to get a user to take a targeted action: installing or downloading your app or game.

Using CPI, mobile app developers can assess the effectiveness and profitability of their advertising campaigns. If your results don't align with your strategy and you're spending more than expected, it might be time to adjust your methods.

The acceptable or good CPI varies depending on the promotion region, niche or category, platform, and even device. For instance, according to statistics, tablet users are more likely to install games than smartphone users. Furthermore, this metric changes daily.

Generally, the installation cost for Android is lower than that of iOS because there are more mobile products for Android, and its users show a higher adoption rate. To understand what CPI you should aim for, conduct a detailed market analysis. In addition to this parameter, there are other metrics that help evaluate the results of development and optimization.
