CPM and RPM are not the same thing
This distinction causes more confusion than anything else in creator earnings, and getting it wrong leads people to expect several times what they will actually receive.
CPM is cost per mille — what an advertiser pays for a thousand ad impressions. It is an advertiser-side figure and it is the larger number.
RPM is revenue per mille — what you actually receive per thousand video views, after everything has been deducted. This is your real earnings rate, and it is the figure worth tracking.
Why RPM is so much lower
Two deductions separate them. First, not every view sees an ad. Viewers with ad blockers, Premium subscribers, videos where ads were not served, and playbacks that ended before an ad ran all count as views but generate no ad impression. The monetised playback rate is typically somewhere around 40 to 70 percent depending on your audience.
Second, YouTube keeps 45 percent of ad revenue on standard long-form video, passing 55 percent to the creator. On Shorts the split is considerably less favourable, and Shorts RPM is generally a small fraction of long-form.
The combined effect is that an RPM is often somewhere between a quarter and a half of the headline CPM.
What drives your rate
Niche matters more than anything else, because advertisers bid according to what a viewer is worth to them. A finance channel earns multiples of an entertainment channel at identical view counts, because a viewer researching investment products is commercially valuable and a viewer watching a comedy sketch is not.
Audience geography matters nearly as much. Views from the United States, Canada, Australia, the UK and Western Europe attract far higher bids than views from most other markets — often by a factor of five or more. Two channels with identical view counts can earn very differently on geography alone.
Video length affects it too, since videos over eight minutes permit mid-roll ads. Seasonality is real and pronounced: rates peak in the fourth quarter as advertising budgets are spent and drop sharply in January.
Ads are usually not the main income
Most established creators earn considerably more from sponsorships, affiliate links, their own products, memberships and merchandise than from AdSense. Ad revenue is the most visible income stream and often the smallest.
A channel with a small but commercially valuable audience can out-earn a much larger entertainment channel through direct sponsorship, because sponsors pay for audience fit rather than raw view count.
Treat the figures as rough
The niche table is a general guide compiled from commonly reported ranges, not a guarantee. Your own analytics are the only reliable source — YouTube Studio reports your actual RPM directly, and using that figure here will give you a far better projection than any published average.

Frequently Asked Questions
What is the difference between CPM and RPM?
CPM is what advertisers pay per thousand impressions. RPM is what you actually receive per thousand video views after YouTube's 45 percent share and unmonetised views are deducted.
Why is my RPM so much lower than reported CPMs?
Because only some views show ads, and YouTube keeps 45 percent of what remains. An RPM is often a quarter to a half of the headline CPM.
What affects earnings most?
Niche and audience geography. Finance content earns multiples of entertainment, and views from high-value markets can be worth five times more than others.
Is ad revenue the main income for creators?
Usually not. Sponsorships, affiliates, products and memberships typically exceed AdSense for established channels.
Where do I find my real RPM?
YouTube Studio reports it directly in your analytics. Using your own figure gives a far better projection than any published average.
