RPD stands for Revenue Per Download and is a metric used to measure how much revenue a company earns on average each time its app or game is downloaded.
To calculate the RPD of an app, divide the total revenue by the total number of downloads.

If a mobile game generates $500,000 in revenue from 1,000,000 downloads:
RPD = 500,000 / 1,000,000 = 0.50
So the RPD is $0.50, meaning the company earns 50 cents per download.
RPD is a key metric for understanding how effectively a mobile app generates revenue from each user download. It offers a clear view into the app’s monetization performance, helping developers and marketers assess whether their acquisition efforts are translating into financial return.
