Formula

#
Core Formula
Monthly ad requests = daily active users x sessions per user per day x ads per session x 30Monetized impressions = monthly ad requests x fill rateEstimated monthly revenue = (monetized impressions / 1,000) x eCPM

How it works: App ad revenue starts with user activity. Daily active users create sessions, sessions create ad requests, fill rate reduces those requests to monetized impressions, and eCPM translates those impressions into estimated revenue.

Worked Example

Suppose your app has 8,000 daily active users, each user opens the app 2.4 times per day, you show 1.8 ads per session, fill rate is 92%, and eCPM is $7.
1Step 1: Monthly ad requests = 8,000 x 2.4 x 1.8 x 30 = 1,036,800
2Step 2: Monetized impressions = 1,036,800 x 92% = 953,856
3Step 3: Monthly revenue = (953,856 / 1,000) x $7 = $6,676.99
4Step 4: Yearly revenue = $6,676.99 x 12 = $80,123.88

How Mobile App Advertising Revenue Is Usually Forecast

App monetization depends on both user scale and user frequency. Two apps with the same DAU can earn very different amounts if one has more sessions, better fill, or stronger advertiser demand.

  • DAU sets the foundation for total ad opportunities
  • Session frequency often matters as much as raw installs
  • Fill rate and eCPM are major levers for monetized inventory quality
  • Revenue per active user helps compare different app monetization models

Use this calculator to compare light, moderate, and aggressive ad-load strategies before you change product monetization.

Frequently Asked Questions

How do you calculate mobile app ad revenue?

A common estimate multiplies daily active users by sessions per user, ads per session, and 30 days to get monthly ad requests. Fill rate adjusts that number down to monetized impressions, and eCPM converts impressions into revenue.

What is eCPM in an app ad revenue calculator?

eCPM is effective revenue per 1,000 monetized impressions. If your app generates 500,000 monetized impressions at a $6 eCPM, that points to about $3,000 in monthly ad revenue.

Why does fill rate matter for app ads?

Fill rate measures how many potential ad requests actually become paid impressions. An app with strong usage but weak fill may leave a lot of inventory unsold, which lowers the real revenue outcome.

Can I use this as an AdMob revenue calculator?

Yes, as a planning estimate. The model is useful for AdMob-style monetization because it focuses on DAU, session frequency, ad load, fill rate, and eCPM rather than assuming one flat payout.

What is a good number of ads per session?

That depends on retention and user experience. More ads per session can increase inventory, but aggressive ad load may reduce engagement and long-term user value. It is usually best to test multiple ad-load scenarios rather than assuming the maximum is best.

Does this work for both Android and iPhone apps?

Yes. The calculator is platform-agnostic. You can use it for Android, iPhone, game apps, utility apps, and content apps as long as you enter realistic activity and eCPM assumptions.
