If you're a YouTube creator trying to understand how much you earn per view, you'll encounter two metrics: CPM and RPM. They're related but measure different things, and confusing them can make your earnings analysis wildly inaccurate.
What is CPM?
CPM stands for Cost Per Mille (cost per 1,000 ad impressions). It represents what advertisers pay YouTube for their ads to appear on videos. If an advertiser has a $10 CPM, they pay $10 per 1,000 times their ad is shown. CPM is an advertiser-facing metric — it's what brands pay, not what creators receive.
What is RPM?
RPM stands for Revenue Per Mille (revenue per 1,000 video views). It represents what creators actually receive per 1,000 views of their content — after YouTube takes its ~45% revenue share. RPM accounts for all monetized playbacks, not just ad impressions. If your CPM is $5, your RPM is roughly $2.50–$2.75 after YouTube's cut.
CPM vs RPM: Key Differences
| Who it measures | Advertiser spend vs. Creator revenue |
| YouTube revenue share | CPM is before; RPM is after YouTube's 45% |
| Per unit | CPM per 1,000 ad impressions; RPM per 1,000 total views |
| Typical value | CPM $1–$50; RPM $0.50–$25 |
Why is My RPM Lower Than CPM?
Your RPM will always be lower than your CPM for two reasons: (1) YouTube keeps ~45% of ad revenue. (2) Not all views show ads — views from YouTube Premium subscribers, some mobile views, and other sources don't include traditional ads. If 60% of your views are monetized and CPM is $5, your RPM calculates to roughly $5 × 60% × 55% = $1.65 RPM.

How to Increase Your RPM
To maximize your RPM: target advertiser-friendly niches (finance, tech, education); create longer videos (15+ minutes allow mid-roll ads); optimize for US/UK/CA audiences (higher CPM markets); upload consistently (algorithm rewards regular posting); use end screens and cards to increase session watch time.
