Ad revenue is the income apps earn from in-app advertising which could be banner ads, interstitial ads, native ads, gamified ads, and rewarded ads. App ad revenue is calculated as: Ad revenue = impressions * eCPM (effective Cost Per Mille, or cost per thousand impressions).
How Ad Revenue Works
Revenue Generation Process
App developers create designated spaces within their applications where advertisers can display promotional content. The basic process follows these steps:
- Ad Space Creation: Developers implement ad units within their app
- Ad Network Integration: Connection to ad networks or mediation platforms
- Ad Serving: When users open the app, ad requests are sent to networks
- Impression Generation: Ads are displayed to users
- User Interaction: Users may view, click, or complete actions on ads
- Revenue Accrual: Developers earn revenue based on the chosen monetization model
Ad Revenue Models
Impression-Based (CPM)
- Definition: Revenue earned per thousand ad impressions
- Formula: Revenue = (Impressions ÷ 1,000) × CPM rate
- Example: 100,000 impressions with $5 CPM = $500 revenue
- Best for: Apps with high traffic volume
- Typical CPM Ranges: $2-$5 for banners, $10-$20 for rewarded video
Click-Based (CPC)
- Definition: Revenue earned when users click on advertisements
- Formula: Revenue = Clicks × CPC rate
- Example: 1,000 clicks with $0.50 CPC = $500 revenue
- Best for: Apps with high engagement rates
- Typical CPC Ranges: $0.20-$1.00 depending on category and region
Action-Based (CPA)
- Definition: Revenue earned when users complete specific actions after clicking
- Formula: Revenue = Completed Actions × CPA rate
- Example: 100 app installations with $5 CPA = $500 revenue
- Best for: Apps with strong conversion ability
- Typical CPA Ranges: $2-$50 depending on the value of the action
Revenue Share
- Definition: Percentage of revenue generated from advertiser campaigns
- Formula: Revenue = Total Advertiser Spend × Revenue Share Percentage
- Example: $10,000 campaign with 30% revenue share = $3,000 revenue
- Best for: Premium publishers with valuable audiences
- Typical Share Percentages: 20%-70% depending on publisher leverage
Ad Format Revenue Potential
| Ad Format | Average eCPM Range (2025) | User Experience Impact | Implementation Complexity |
|---|---|---|---|
| Banner Ads | $0.50-$3.00 | Low to Moderate | Simple |
| Interstitial Ads | $3.00-$10.00 | High | Moderate |
| Native Ads | $3.00-$8.00 | Low | Complex |
| Rewarded Video | $10.00-$20.00 | Positive | Moderate |
| Playable Ads | $10.00-$25.00 | Moderate to Positive | Complex |
| Offerwall | $8.00-$15.00 | Moderate | Complex |
Ad Revenue Calculation In Depth
Understanding eCPM
eCPM (effective Cost Per Mille) represents the actual revenue generated per 1,000 ad impressions across all revenue models.
Calculation Formula
eCPM = (Total Ad Revenue ÷ Total Impressions) × 1,000
Example Calculation
- Total Revenue: $1,500
- Total Impressions: 500,000
- eCPM = ($1,500 ÷ 500,000) × 1,000 = $3.00
ARPDAU Calculation
ARPDAU (Average Revenue Per Daily Active User) is a critical metric that shows daily revenue per user.
Formula
ARPDAU = Daily Ad Revenue ÷ Daily Active Users
Example
- Daily Ad Revenue: $500
- Daily Active Users: 10,000
- ARPDAU = $500 ÷ 10,000 = $0.05
LTV from Ad Revenue
LTV (Lifetime Value) represents the total ad revenue expected from a user throughout their app usage.
Basic Formula
Ad Revenue LTV = ARPDAU × Average User Lifetime (in days)
Enhanced Formula
Ad Revenue LTV = ∑(Daily Revenue from User / Number of Active Users on that Day) over expected lifetime
Comparing Ad Revenue to Other Monetization Models

Importance of Ad Revenue
Ad revenue is a crucial revenue source, especially for Hyper Casual and Casual gaming apps because of their low rates of IAP (in-app purchasing). It provides several key benefits:
Business Benefits
- Accessibility: Monetizes the entire user base, not just paying users
- Scalability: Revenue grows directly with user acquisition
- Immediacy: Begins generating income from day one
- Low Barrier: Doesn’t require users to commit to purchases
- Complementary: Can work alongside other revenue models
User Engagement Benefits
When users’ engagement with the ads increases, this will inevitably result in retention, and ultimately revenue. For instance, gaming apps can use rewarding ads to give in-game rewards and incentivize the users to increase engagement and play the game consecutively for various prizes.
Strategic Importance
- Market Testing: Enables monetization during early product validation
- Audience Building: Supports free user acquisition for later conversion
- Revenue Diversification: Reduces dependence on small paying user base
- Competitive Alternative: Offers free option in competitive markets
- Brand Relationship Building: Creates connections with advertising partners
