Ad Revenue Calculator

About this calculator

A free, instant tool for estimating ad revenue from mobile apps, games, and websites. No sign-up, no paywall, no data sent anywhere.

What it is

This calculator takes your platform, category, audience size, geographic mix, and ad format choices and estimates monthly ad revenue across every major network. All math runs in the browser using published eCPM and RPM benchmarks. Nothing is stored or sent to a server.

You can also switch to the Compare Networks tab to see every network ranked side by side for your exact inputs, or the Format Guide to understand how each ad format works before committing to a setup.

Why I built it

I kept running into the same problem: when I tried to estimate what a mobile app or website could earn from ads, I could not find a free tool that actually let me compare networks with my own numbers. Most resources either gave vague ranges or required a sign-up. So I built one.

The goal is simple: give developers, indie game studios, and content creators a fast, honest estimate they can use to make real decisions, without having to sift through blog posts or sign up for anything.

Methodology

Every eCPM and RPM figure in the calculator is a blended estimate calibrated against published 2025 industry benchmarks. Here is exactly how the math works.

What the values represent

The numbers represent a well-run app or site with good ad placements, not the median publisher and not the top 5%. A typical new app will start lower; a highly optimized app at scale can exceed these figures.

Tier system

Each network stores rates as three tiers:

  • Tier 1: US, UK, AU, CA (highest advertiser demand)
  • Tier 2: Western Europe and developed APAC markets
  • Tier 3: Asia, LatAm, Africa (lowest advertiser rates)

The geographic mix slider blends linearly across these three tiers.

Mobile eCPM calculation

For mobile apps and games, the formula per format is:

Monthly revenue = DAU x ads per user per day x blended eCPM / 1,000 x 30

Each enabled ad format is calculated separately and summed. iOS gets a 1.3x premium over Android, reflecting consistently higher advertiser demand documented across major ad networks.

Category multipliers

Each app category carries a multiplier relative to a casual game (1.0x baseline). Finance apps earn significantly more because financial advertisers pay high CPCs. Hypercasual games earn less because their large but lower-intent audiences attract lower bids. Education and productivity apps tend to underperform gaming in ad monetization because users are more ad-averse in those contexts.

Web RPM calculation

For websites:

Monthly revenue = monthly visitors / 1,000 x RPM

RPM (revenue per mille) is already a per-pageview rate. Category multipliers apply here too: finance and tech sites command premium rates from high-CPC advertisers.

Data sources

The eCPM and RPM benchmarks were calibrated against these published reports. Where sources conflicted, we used the conservative midpoint or favored the more recent data.

Data was last calibrated in June 2026. Ad rates shift with season (Q4 is always highest) and as markets evolve, so treat all estimates as a directional range, not a guarantee.

Feedback and corrections

If you have real data from your own app or site that differs significantly from the estimates here, or you spot an error in the methodology, reach out. Accurate benchmarks help everyone using the tool.

If you have real publisher data that differs significantly from these estimates, sharing it helps improve accuracy for everyone. Feedback is always welcome.
