How does YouTube calculate RPM, CPM, and ad revenue shares?
Many creators check their analytics and see terms like CPM, RPM, and revenue share, but few understand how the numbers are calculated. This is why two channels with similar views can earn completely different amounts.
This guide breaks down how YouTube calculates revenue, where money comes from, how much advertisers pay, and how much creators keep after YouTube takes its share.
📌 What actually generates money on YouTube?
YouTube earnings come from multiple revenue pools: in-stream ads, Shorts feed revenue share, YouTube Premium watch time, shopping integrations, and brand deals. CPM and RPM only reflect ad-based earnings—not external income like sponsorships.
💰 Main revenue sources that affect RPM
- Display ads & skippable in-stream ads
- Non-skippable ads & bumper ads
- Shorts revenue pool (shared globally by views)
- YouTube Premium watch time
📍 What is CPM?
CPM (Cost Per Mille) is how much advertisers pay YouTube per 1,000 monetized impressions. It’s an ad-market metric, not a payout metric.
Formula:
CPM = (Advertiser Spend ÷ Monetized Views) × 1,000
Key insight
High CPM doesn’t mean high earnings—it's before revenue share, taxes, invalid traffic, and fill rates are applied.
📍 What is RPM?
RPM (Revenue Per Mille) shows how much a creator earns per 1,000 total views. It includes all YouTube revenue, not just ads.
Formula:
RPM = (Creator Earnings ÷ Total Views) × 1,000
RPM is what creators should track—not CPM—because it reflects real earnings.
📍 Why CPM and RPM are different
- CPM measures advertiser spending
- RPM measures creator payout
- CPM ignores total views; RPM includes all views
- CPM excludes revenue share; RPM reflects earnings after YouTube cut
📉 Why two channels with similar views earn differently
Earnings shift based on niche, audience geography, device type, retention, watch time, and advertiser demand.
Example:
- Finance RPM → $8–$22
- Comedy RPM → $0.80–$3
- Gaming RPM → $1–$4
- Tech education RPM → $5–$14
🧮 How revenue share works (Long-form videos)
YouTube typically takes 45% of ad revenue after invalid traffic adjustments. Creators get the remaining 55% for eligible content.
Formula:
Creator Earnings = Total Ad Revenue × 0.55
🧮 How Shorts revenue share works
Shorts ads go into a global revenue pool, then are distributed based on watch time share—not individual CPM.
Formula (simplified):
Creator Earnings = (Your Watch Time Share ÷ Global Total) × Pool × 0.45
📊 Why Premium revenue pays differently
Premium pays based on watch time, not ads. It often has higher RPM because there are no skipped ads, reducing waste.
📍 Why advertisers pay different rates
Advertisers bid based on intent and conversion probability. A viewer watching “How to start dropshipping” signals purchase intent, while a viewer watching “funny dog challenge” signals entertainment. Higher purchase intent = higher ad bids = higher CPM.
Major factors that influence advertiser spending
- Keyword commercial value
- Audience income level
- Device type (TV + Desktop earn more)
- Country of viewer (US > Canada > UK > India > Africa)
- Season (Q4 campaigns pay highest)
🌍 Location impact on CPM & RPM
Advertisers spend more in countries with strong economies. A Nigerian viewer may generate $0.20 RPM while a US viewer may generate $12+ even on similar content.
Average RPM by region
- United States → $8 – $22
- Canada → $6 – $15
- United Kingdom → $5 – $12
- Brazil → $1 – $3
- Nigeria → $0.05 – $0.40
Same video, different countries = different earnings.
🧠 Case Study 1 — Same views, different RPM
Two channels each upload a 10-minute video that gets 100,000 views.
Channel A (Finance in USA)
- CPM: $25
- RPM: $14
- Earnings: (100,000 ÷ 1000) × 14 = $1,400
Channel B (Comedy in India)
- CPM: $2
- RPM: $0.80
- Earnings: (100,000 ÷ 1000) × 0.80 = $80
Same views. One earns 17x more because of niche + geography + advertiser demand.
📌 How to increase RPM as a creator
The goal isn’t more views — it’s attracting audiences that advertisers value more.
Best strategies
- Post search-based & tutorial content
- Target US/UK audiences using topics & titles
- Prioritize 8–12 minute videos (multiple ad slots)
- Improve watch time → unlock higher ad inventory
- Create niche content with buying intent
📈 How to calculate your own RPM
You can manually compute your RPM even outside analytics.
Example: Total earnings = $265.40 Total views = 43,910 RPM = (265.40 ÷ 43,910) × 1000 = $6.04
Tracking RPM monthly helps measure growth beyond vanity metrics like views and subscribers.
🧪 Case Study 2 — Fixing low RPM
A gaming creator had 6M views but earned only $900 due to low advertiser value and Shorts-heavy traffic.
Fix applied:
- Switched from random entertainment to “How to build a streaming setup” guides
- Used search-based titles targeting US audiences
- Added product links (affiliate ads + long videos)
RPM jumped from $0.15 to $5.20, and monthly revenue increased 34x without more views.
🧠 Final takeaway
YouTube earnings aren’t random — they're a reflection of audience quality, niche value, monetization type, geography, and how advertisers bid. RPM is the metric that reflects real creator earnings. Optimize for value, not just viral reach.
