What is YouTube CPM?
YouTube CPM is the amount advertisers pay per 1,000 ad views on your videos — before YouTube takes its share. It's a cost to the advertiser, not the money that lands in your pocket. What you actually keep is your slice of that: creators earn 55% of ad revenue, and YouTube keeps 45%.
That's the single biggest thing to understand about creator earnings — a high CPM looks great, but your take-home is a little over half of it, and only on the views that actually showed an ad.
CPM vs RPM — the number that matters
Creators mix these up constantly, so it's worth being clear:
- CPM — what advertisers pay per 1,000 ad views, before YouTube's cut.
- RPM — what you earn per 1,000 total views, after the 45% cut and after counting views that showed no ad.
Because of those two deductions, your RPM is always lower than your CPM — often roughly half or less. RPM is the honest measure of what your channel earns. For the full breakdown of how these relate, see CPM vs RPM explained, and the eCPM calculator for the publisher side.
How YouTube earnings are calculated
To estimate your earnings, take the views that showed ads, divide by 1,000, multiply by your CPM, then multiply by your 55% share:
Earnings = (Monetised views ÷ 1,000) × CPM × 55%
The calculator above does this for you and also shows the implied RPM — your earnings per 1,000 views — so you can see the gap between the advertiser's CPM and your real take-home. The share is editable in case your split differs.
A worked example
Say a video earns 200,000 monetised views at a $10 CPM, and you keep the standard 55%:
$1,100 = 200,000 ÷ 1,000 × $10 × 55%
So the $10 CPM turns into about $1,100 in your pocket — an RPM of $5.50 per 1,000 monetised views. Spread across your total views (including the ones with no ad), your reported RPM would be lower still.
