YouTube RPM vs CPM: What Each Number Actually Means for Your Earnings
CPM is what advertisers pay. RPM is what you keep. Understanding the gap between them is the difference between guessing at your income and forecasting it.
Two creators can both report a "$10 CPM" and earn wildly different amounts. The number that determines your income is RPM, and it is almost always far lower than the CPM figure creators quote to each other.
CPM: cost per mille
CPM is what advertisers pay for one thousand ad impressions. It is an advertiser-side metric. In YouTube Studio you will see it reported as playback-based CPM, calculated across monetized playbacks only — the subset of your views where an ad actually ran.
Crucially, CPM is measured before YouTube takes its share, and it only counts views that carried an ad. If half your views serve no ad at all, CPM tells you nothing about those views.
RPM: revenue per mille
RPM is what you earned per thousand views, across all your views, after YouTube's revenue share. It is the creator-side metric and the honest one.
The formula is simple:
“RPM = (your total estimated revenue / total views) × 1,000”
Because the denominator is total views rather than monetized playbacks, and the numerator is your cut rather than the advertiser's spend, RPM is typically somewhere between a quarter and a half of the CPM figure for the same content.
Why the gap is so wide
Three separate reductions sit between an advertiser's spend and your bank account.
- Not every view carries an ad. Viewers with ad blockers, YouTube Premium subscribers, videos flagged as limited-advertiser-suitable, and short viewing sessions often produce no ad impression at all.
- YouTube takes its share. For long-form video, creators receive 55% of net advertising revenue. For Shorts, the arrangement is different — revenue enters a shared pool, music licensing is paid out first, and creators receive 45% of what remains allocated to them.
- RPM includes revenue beyond ads. Channel memberships, Super Thanks, and YouTube Premium revenue all count toward RPM, which can push it up for channels with strong direct fan support.
What a typical RPM looks like
RPM varies more by topic than by any other factor. Broad ranges seen across the creator economy, which you should treat as rough orientation rather than a promise:
- Finance, investing, insurance and B2B software: the highest band, often several multiples of the platform average.
- Technology reviews, business and education: comfortably above average.
- Lifestyle, food, fitness and travel: around the platform average.
- Gaming, entertainment, music and vlogs: typically below average, because the audience is younger and advertiser competition is lower.
- Shorts: dramatically lower than long-form across every niche, often by an order of magnitude.
Geography compounds this. The same video shown to a viewer in the United States, Germany or Australia generates far more advertiser competition than one shown in a market with lower ad spend. Two channels in the same niche with identical view counts can differ several-fold in RPM purely on audience location.
Which one should you optimise?
Optimise RPM. CPM is largely set by advertiser demand in your niche and your audience's location — you influence it only indirectly, by changing who watches you. RPM responds to decisions you control.
- Enable more ad formats. Mid-roll ads on videos over eight minutes are the single biggest RPM lever available to most channels.
- Increase watch time per video. Longer genuine watch sessions create more ad slots.
- Add non-ad revenue. Memberships and Super Thanks flow into RPM and are not subject to advertiser seasonality.
- Shift topic mix at the margin. You do not need to abandon your niche — a gaming channel covering PC hardware purchases will see a different RPM than one covering gameplay alone.
- Watch your advertiser-suitability ratings. Videos limited for advertisers lose most of their ad inventory.
Seasonality is real and predictable
Advertising budgets follow the calendar. RPM across most niches peaks in the fourth quarter as brands spend holiday budgets, then falls sharply in January when those budgets reset. A drop of a third or more between December and January is normal and is not a sign that anything is wrong with your channel.
If you are comparing your performance month to month, compare against the same month last year rather than against the previous month.
