RPM — Revenue Per Mille (Latin for “thousand”) — is the number YouTube creators actually care about. It’s the closest single-number proxy for “how much am I earning per view.”
The formula
$$ RPM = \frac{\text{Total AdSense revenue}}{\text{Total views} \div 1{,}000} $$
If your channel earned $600 last month on 100,000 views, your RPM was $6.
Simple. But underneath, RPM is the product of several independent signals YouTube negotiates against advertiser demand — and each one is a lever you can pull.
The five levers that actually move RPM
1. Niche. The single biggest factor. Personal Finance runs $18–$45. Sleep content runs $3–$8. Same platform, 5× spread. If RPM is your primary goal, niche selection is 60% of the outcome.
2. Video length. Videos under 8 minutes get one pre-roll ad. Videos over 8 minutes get mid-rolls, and each mid-roll roughly doubles per-video ad revenue. A channel that switches from 6-minute to 12-minute average length typically sees RPM jump 40–80% within a quarter.
3. Audience geography. Tier-1 markets (US, UK, CA, AU, DE, Nordics) pay 3–5× the RPM of tier-3 markets. This isn’t a subscriber-count issue — it’s an audience-composition issue.
4. Retention. YouTube surfaces high-retention videos to advertisers with better budgets. A 65% retention rate meaningfully unlocks better ad categories than a 40% retention rate on the same content.
5. Season. Q4 RPMs run 40–70% higher than Q1 across the platform. January is the worst month; November is the best. This is purely an advertising-budget cycle, not anything about your channel.
What RPM doesn’t measure
RPM only reflects AdSense revenue. It excludes:
- YouTube Premium revenue (5–15% of AdSense typically)
- Channel memberships, Super Chat, Super Thanks
- Merch shelf revenue
- Sponsorships (often equal to or exceed AdSense past 50k subs)
- Affiliate revenue
- Newsletter or course revenue driven by the channel
For most established faceless channels, RPM is 60–75% of total channel revenue per view. The RPM number is directional, not complete.
