CPM (cost per 1,000 monetized impressions)

$8.00

Calculation

CPM = Ad revenue ÷ Monetized impressions × 1,000

  1. $1,200.00 ÷ 150,000 × 1,000 = $8.00

CPM is what advertisers pay before YouTube's revenue share, counted only on impressions that showed an ad. RPM is what you earn per 1,000 of all views, after the revenue share. RPM is usually lower than CPM.

Good to know

What is CPM on YouTube?

CPM (cost per mille) is the price advertisers pay for 1,000 ad impressions. On YouTube, the CPM in Studio is calculated on monetized impressions — times an ad was actually shown — and before YouTube's revenue share.

CPM vs RPM

  • CPM = ad revenue ÷ monetized impressions × 1,000. Advertiser's side, gross.
  • RPM = total revenue ÷ all views × 1,000. Creator's side, net.

RPM is usually lower because it's after the revenue share and includes views without ads. Enter your total revenue and views in the optional fields to see both side by side. More detail in our RPM vs CPM guide.

Example

$1,200 of ad revenue from 150,000 monetized impressions: $1,200 ÷ 150,000 × 1,000 = a CPM of $8.00.

Limitations

  • CPM measures advertiser demand, not your income — use RPM to estimate earnings.
  • A single view can carry several ad impressions, so impressions and views aren't interchangeable.

FAQ

Frequently asked questions

Why is my CPM higher than my RPM?

CPM is gross and counted only on impressions with ads. RPM is net of YouTube's share and divided by every view, including views with no ads.

Can I increase my CPM?

CPM depends mostly on advertiser demand for your audience and topic, and on the season. It isn't a setting you control directly.

Is playback-based CPM the same thing?

Playback-based CPM counts playbacks with at least one ad instead of individual impressions. Use whichever figures match the numbers you enter.
