How AdMob CPM Works

From app open to ad revenue — the AdMob mediation and auction process that determines your eCPM.

AdMob eCPM = (Ad Revenue ÷ Ad Impressions) × 1,000

What is AdMob CPM Calculator?

An AdMob CPM calculator is a free tool that computes the effective CPM (eCPM) for mobile app advertisements served through Google AdMob. It helps app developers and publishers estimate their ad revenue per 1,000 impressions across different ad formats.

Google AdMob is the leading mobile app monetization platform, used by over 1 million apps worldwide. It supports banner ads, interstitial ads, rewarded video ads, and native ads. AdMob eCPMs vary dramatically by ad format — rewarded video typically earns 5–10× more than banner ads.

This calculator helps you forecast revenue based on your app's traffic patterns. Whether you're building a game, utility app, or content app, understanding your eCPM is essential for making informed decisions about your monetization strategy and ad placement optimization.

AdMob CPM Calculator Formula

AdMob eCPM = (Ad Revenue ÷ Ad Impressions) × 1,000
Solve for Ad Spend
Ad Revenue = (eCPM × Ad Impressions) ÷ 1,000
Solve for App Ad Impressions
Ad Impressions = (Ad Revenue ÷ eCPM) × 1,000
AdMob eCPM Calculation Example

A mobile game earns $300 from AdMob with 200,000 ad impressions in a month. The eCPM is: ($300 ÷ 200,000) × 1,000 = $1.50 eCPM. For rewarded video ads specifically, this same app might see $8–$15 eCPM, while banner ads contribute only $0.30–$0.80 eCPM.

How to Improve AdMob CPM

Strategies to increase your AdMob eCPM and maximize mobile app ad revenue.

Higher eCPMs mean more revenue from the same app traffic. These strategies help mobile developers optimize AdMob performance.

Your Progress
0 / 7 strategies
Rewarded video has the highest eCPM ($10–$25). Place rewarded ads at natural break points where users want to earn in-app currency or unlock content.
AdMob mediation lets multiple ad networks compete for your inventory. More competition = higher eCPMs. Add Meta Audience Network, Unity Ads, and ironSource as mediation partners.
Show interstitial ads every 3–5 user actions, not every screen. Over-showing ads causes user churn, which ultimately hurts eCPM and revenue.
Users from the US, UK, Japan, and Australia have 3–8× higher eCPMs than users from India or Southeast Asia. Optimize user acquisition for Tier-1 regions.
AdMob bidding (real-time auction) typically outperforms waterfall mediation by 15–25%. Enable open bidding for all supported ad networks.
Place banner ads in visible screen areas — not below scrollable content. Viewable impressions earn higher eCPMs because advertisers pay premium for confirmed views.
Use Firebase A/B testing to compare ad placements, formats, and frequency caps. Data-driven optimization consistently outperforms guesswork.

AdMob CPM Calculator FAQ

Common questions about AdMob eCPM, mobile ad revenue, and monetization optimization.

A good AdMob eCPM varies by format: Banner: $0.30–$1.50. Interstitial: $3–$10. Rewarded Video: $8–$25. iOS generally earns 20–40% higher eCPM than Android. US/UK traffic can be 3–8× higher than global averages.

Mobile banner ad eCPMs are lower because: (1) Smaller screen size = less ad visibility. (2) Accidental clicks are filtered. (3) Mobile users have shorter attention spans. However, rewarded video and interstitial eCPMs can exceed desktop AdSense.

Improve fill rate by: (1) Using AdMob mediation with multiple networks. (2) Setting appropriate floor prices (not too high). (3) Enabling all ad formats. (4) Keeping your app content policy-compliant. A 95%+ fill rate is achievable with proper mediation setup.

Yes. Finance apps: $10–$30 eCPM. Shopping: $5–$15. Games: $3–$12 (rewarded). Utilities: $1–$5. Education: $2–$8. High-value categories attract premium advertisers willing to pay more per impression.

AdMob is designed for mobile apps with native SDK integration, mediation, and mobile-specific formats (rewarded video, app open). AdSense is for websites. For mobile apps, always use AdMob — it provides higher eCPMs and better mobile ad formats.
