What Is CPI?
CPI stands for Cost Per Install and means that a payout is triggered every time an ad causes an installation. It generally refers to mobile ads, where the thing being installed is an app. It is essentially a variation of the CPA (Cost Per Action) ad pricing model.
CPI is primarily used in mobile app marketing to measure how much it costs to acquire a new user who installs your app. This metric is crucial for app developers and marketers to evaluate the efficiency of their user acquisition campaigns and to optimize their marketing budgets.
Unlike other metrics like CPC (Cost Per Click) or CPM (Cost Per Mille), which measure the cost of engagement or impressions, CPI specifically focuses on the end goal for most app campaigns: getting users to install the app. This makes it a more direct measure of campaign success for app marketers.
However, it's important to note that CPI doesn't measure the quality of users acquired. An install doesn't necessarily translate to an active or paying user, which is why it's often used alongside metrics like LTV (Lifetime Value) and retention rates.
CPI Formula
The CPI calculation formula is straightforward:
CPI = Ad Spend ÷ Installs
For example, if you spent $5,000 on a mobile app campaign and generated 1,000 installs, your CPI would be:
$5,000 ÷ 1,000 = $5.00 per install
This means it cost you $5.00 to acquire each new app user through your campaign.
What Is A Good CPI?
What constitutes a "good" CPI varies significantly across app categories, regions, platforms (iOS vs. Android), and campaign objectives. However, here are some general benchmarks to help you evaluate your performance:
Low: $0.50-$1.50
Typically achievable for simple utility apps or games in less competitive markets or regions with lower costs.
Average: $1.50-$3.00
Many apps across various categories fall within this range, particularly for campaigns targeting tier 2 and tier 3 countries.
High: $3.00-$10.00+
Common for competitive categories like finance, dating, or high-value gaming apps, especially when targeting tier 1 countries.
Remember that a higher CPI isn't necessarily bad if the users you're acquiring have a higher lifetime value (LTV). The key is to ensure that your LTV:CPI ratio is positive and maximized.
