CPM & RPM Results
CPM vs RPM
CPM (Cost Per Mille) is what advertisers pay per 1,000 ad impressions. RPM is what you actually earn per 1,000 views after YouTube's 45% cut. RPM is always lower than CPM.
How the Formula Works
Variables
CPMCost Per Mille — what advertisers pay per 1,000 ad impressionsRPMRevenue Per Mille — creator earnings per 1,000 total views0.45YouTube's revenue share (45% of gross ad revenue)Worked Example
If YouTube Studio shows your RPM as $4.50, your advertiser CPM is approximately $4.50 / 0.55 = $8.18. A video with 200,000 views earns $4.50 × 200 = $900.
•RPM shown in YouTube Studio already accounts for YouTube's cut — it is your actual take-home per 1,000 views
•CPM fluctuates throughout the year — typically 30–60% higher in Q4 than Q1
CPM vs. RPM: The Essential Distinction
CPM is a metric that belongs to advertisers. RPM is your metric as a creator. When a brand says "we pay a $15 CPM," they mean $15 per 1,000 impressions to run their ad. You receive 55% of that — your RPM is $8.25. The gap matters when evaluating your channel's business performance.
Why Your RPM Changes
RPM fluctuates due to seasonality (Q4 advertising spend is highest), niche (high-value audiences command more advertiser spend), viewer location (US/UK viewers are worth significantly more), content format (longer videos with mid-rolls earn more), and the age of your videos (older content still generating views at lower engagement may have lower fill rates).
Frequently Asked Questions
A good CPM depends heavily on niche. Personal finance and investing channels see $15–$45 CPM. Tech channels see $8–$20. Gaming channels often see $2–$8. "Good" means anything above the niche average for your audience geography.
