YouTube RPM vs. CPM Ad Revenue Calculator

Calculate your effective YouTube RPM from CPM, monetized impressions and total views, using the Partner Program's 55% revenue share.

Views that actually served a paid ad — always ≤ total views

55% is YouTube's standard Partner Program share for every creator

$3.30 RPM

Gross ad revenue $600.00, your share $330.00 (60% of views were monetized).

CPM and RPM answer two different questions

CPM answers "what does an advertiser pay per 1,000 ad impressions" — a number about the ad market for your specific audience. RPM answers "what do I actually earn per 1,000 views" — a number about your channel's whole audience, most of whom never triggered a monetized ad impression in the first place. Confusing the two is the single most common mistake new creators make when trying to estimate revenue from a CPM figure they've seen quoted somewhere.

Where the gap between CPM and RPM actually comes from

Two multipliers separate them: YouTube's 45% platform cut (creators keep 55% of AdSense revenue, a fixed rate regardless of channel size), and the fact that not every view serves a monetized ad — some viewers have ad blockers, some inventory goes unsold, and some watch sessions simply don't trigger an ad break. A channel with a $10 CPM but only a 40% monetized-impression rate ends up with an RPM closer to $2.20 than the $5.50 a naive "55% of CPM" calculation would suggest.

Why Shorts RPM usually looks lower than long-form

It's rarely a sign anything is wrong — short vertical video simply has less room for ad breaks and, historically, faces different (often lower) advertiser demand than long-form content, which shows up as both a lower CPM and a lower monetized-impression rate for the same channel. Compare Shorts and long-form RPM using this tool with each format's own real inputs rather than assuming one number should transfer to the other.

How to use this calculator

  1. Enter total views and monetized ad impressions.
  2. Enter your CPM.
  3. See gross ad revenue, your 55% share, and effective RPM.
Creator revenue share
YouTube's standard AdSense revenue share for Partner Program members is 55% of ad revenue, the same rate regardless of channel size, subscriber count or content category.
RPM's denominator is total views
RPM divides creator revenue by every view (monetized or not), while CPM divides advertiser spend only by monetized impressions — that gap is exactly why RPM is normally well below CPM × 55%.

Questions

Why is my RPM so much lower than the CPM I see advertisers paying?

Two things compound: YouTube keeps 45% of ad revenue before you see a cent, and RPM divides what's left by every view — including views that never served a monetized ad at all, because there was no ad inventory sold, an ad blocker was active, or the viewer was skipped past the ad break entirely. CPM only ever divides by monetized impressions, a smaller and more favorable denominator.

Does the 55% revenue share ever change for bigger channels?

No — it's the same 55% for every Partner Program member regardless of subscriber count, channel size, or content category. What varies channel to channel is CPM (what advertisers will pay to reach your specific audience) and monetized impression rate (what fraction of your views actually carry a paid ad), not the revenue split itself.

Is RPM different for Shorts than for long-form video?

The formula and the 55% split are identical, but Shorts typically carries a lower CPM and a lower monetized-impression rate than long-form, because short vertical video has less room for ad breaks and a different advertiser demand curve. Run the same inputs for each format separately rather than assuming one RPM applies across both.

What isn't included in this estimate?

YouTube Premium revenue share (paid out separately, based on watch time, not CPM), channel memberships, Super Chat/Super Thanks, and any brand deals or sponsorships — this tool covers AdSense ad revenue only, which for most creators is one line item among several, not the whole picture.
