Calculate advertiser CPM

Convert ad cost and impressions into one comparable rate.

  1. 01Enter the total number of individual ad impressions for the period.
  2. 02Enter the advertiser cost associated with those same impressions.
  3. 03Compare the resulting CPM across periods, audiences, or campaigns.

CPM formula

Advertiser cost ÷ ad impressions × 1,000

Example

$800 ÷ 100,000 × 1,000 = $8 CPM

Match the cost and impression date ranges. CPM is an advertiser metric and should not be presented as creator take-home revenue.

Impressions are not views

One video view may show no ad, one ad, or multiple ads. Standard CPM uses individual ad impressions rather than total video views.

CPM is not RPM

CPM is advertiser cost before YouTube’s share. RPM is creator revenue after revenue sharing per 1,000 total views.

No payout guess

The result reports ad-market costs only. It does not turn gross advertiser spend into a misleading creator earnings estimate.

Clear answers

YouTube CPM calculator FAQ

What is YouTube CPM?

YouTube CPM is the advertiser cost per 1,000 ad impressions before YouTube’s revenue share. It measures what advertisers pay, not the amount a creator receives.

How do I calculate CPM?

Divide the advertiser cost by the number of ad impressions, then multiply by 1,000. For example, $800 across 100,000 ad impressions equals an $8 CPM.

What is playback-based CPM?

Playback-based CPM uses monetized video playbacks as the denominator instead of individual ad impressions. One playback can contain more than one ad, so playback-based CPM and impression CPM can differ.

Is CPM the same as creator earnings?

No. CPM reflects advertiser cost before revenue sharing and only relates to ads. Creator earnings also depend on revenue share, monetized playbacks, non-ad revenue, and total views.

Why is my YouTube CPM changing?

Advertiser demand changes with audience geography, season, topic, available ad formats, device mix, and competition in the ad auction. Normal CPM can therefore vary between periods and videos.

Should I use CPM or RPM to estimate my income?

Use RPM when you want creator revenue per 1,000 views. Use CPM when you want to understand advertiser cost per 1,000 ad impressions. They answer different questions.
