Impression RPM Calculator

What is Impression RPM?

RPM stands for “Revenue Per Mille,” with “mille” meaning thousand. Impression RPM is a publisher-focused metric that calculates the total ad revenue earned for every 1,000 ad impressions served on a website or app. It provides a holistic view of how effectively a publisher is monetizing their ad inventory.

How to Calculate Impression RPM

The formula for calculating Impression RPM is straightforward:

For instance, if a website earned $300 from 120,000 ad impressions, the Impression RPM would be $2.50. This means the publisher earned, on average, $2.50 for every thousand ads that were displayed.

Why is RPM Important?

While often used interchangeably with eCPM, RPM is a vital metric for publishers for several key reasons:

• Revenue Health Check: It offers a high-level snapshot of the overall health of your monetization strategy. A rising RPM indicates that your strategies are working.
• Performance Benchmarking: RPM allows you to compare the earning potential of different pages, ad units, or traffic sources across your site.
• Strategic Decision Making: By understanding your RPM, you can make better decisions about ad placements, the types of content you create, and the ad networks you partner with to maximize revenue.
• Forecasting: Similar to eCPM, a stable RPM allows you to accurately forecast future ad revenue based on expected traffic levels.
