CPM and RPM are the two numbers behind every YouTube income claim, and confusing them leads to wildly wrong expectations. They measure different things from different points of view. Once the difference clicks, your earnings reports finally make sense.
CPM: what advertisers pay
CPM stands for cost per mille, the amount advertisers pay per 1,000 ad impressions. It is measured before YouTube takes its share and only on monetized impressions. A high CPM means advertisers value your audience, but it is not the money in your pocket.
RPM: what you keep
RPM stands for revenue per mille, the amount you actually earn per 1,000 video views, after YouTube's share and across all revenue sources including ads, memberships, and Super Thanks. RPM is calculated over all your views, not just monetized ones, so it is the honest measure of your earnings.
| CPM | RPM | |
|---|---|---|
| Point of view | Advertiser cost | Your earnings |
| Timing | Before YouTube's cut | After YouTube's cut |
| Counts | Monetized impressions only | All views |
| Use it to | Gauge audience ad value | Estimate take-home income |
Why RPM is the number that matters
Because RPM reflects all your views and all your revenue after YouTube's share, it is the figure to use when projecting income. Take your views, multiply by your RPM, divide by 1,000, and you have a realistic estimate. The money calculator does this for you.
How to raise both
- Choose or lean into higher-value topics within your niche.
- Make longer videos eligible for mid-roll ads, without padding.
- Grow the share of your audience in high-CPM regions through your content focus.
- Diversify revenue so RPM is not purely ad-dependent. See how much YouTubers make.
