CPM is what advertisers pay for 1,000 ad impressions on your videos before YouTube takes its share; RPM is what you earn per 1,000 views after that share, across ads, YouTube Premium, channel memberships, Super Chat and Super Stickers. YouTube's ad revenue analytics page gives two reasons RPM sits lower: it is calculated after the revenue share, and it includes every view, even the ones that showed no ad.
The definitions are short; the confusion comes from treating one metric as a version of the other. This page sets them side by side, explains the second CPM in your reports, flags a counting wrinkle that makes hand calculations drift, and then gives you a worksheet that reconciles RPM and CPM line by line from your own Analytics export.
RPM and CPM side by side
Every row below restates YouTube's own comparison on its ad revenue analytics page.
| Question | RPM | CPM |
|---|---|---|
| Whose number is it? | Creator-focused: what you earned | Advertiser-focused: what advertisers paid |
| Before or after YouTube's share? | After | Before |
| Which revenue is included? | Total revenue reported in Analytics, including ads, Premium, memberships, Super Chat and Super Stickers | Only revenue from ads and YouTube Premium |
| Divided by what? | All views for long-form videos; all engaged views for Shorts | Ad impressions, counting only videos that showed ads |
| What it cannot tell you | Which revenue source caused a swing; income from merch, most brand deals and off-platform work | What you earn: your revenue is not CPM multiplied by views |
The comparison makes one practical point obvious: there is no fixed conversion between the two. RPM adds revenue that CPM ignores and divides by a different count, so the ratio between them moves with your ad-enabled share, your ad load and your fan funding. Any rule of thumb that turns CPM into RPM with a single multiplier is guessing on your behalf.
The second CPM in your reports
Analytics shows two advertiser-side prices. CPM is the cost per 1,000 ad impressions, counted every time an ad displays. Playback-based CPM is the cost per 1,000 video playbacks that showed one or more ads, and because one playback can carry several ads, YouTube says it is often the higher of the two. Its worked example on the ad revenue page has 5,000 views, of which 1,000 showed one ad and 500 showed two, giving 1,500 monetized playbacks and 2,000 impressions; with $7 of advertiser spend, CPM is $3.50 and playback-based CPM is $4.67.
Watch the card names as well as the metrics. The metrics table on YouTube's revenue help page describes a card called How much advertisers pay as your revenue per 1,000 monetized playbacks where one or more ads show, which reads differently from the advertiser-cost definition of playback-based CPM on the other page. Before you compare two periods, hover over the metric in Studio and write down which definition your report is using.
The counting wrinkle
YouTube's RPM page currently says two things that pull in different directions. Its definition says RPM is calculated per 1,000 engaged views, while its comparison table says RPM includes all engaged views for Shorts and all views for long-form videos. The gap between those two counts now matters for long-form as well as Shorts. Since August 24, 2026, YouTube's engagement metrics page says a view counts the moment playback starts in every format, while earnings rest on engaged views and engaged watch hours, and its Shorts help page describes engaged views as the viewers who chose to keep watching.
The safe approach is to treat the RPM Studio shows as authoritative and, whenever you rebuild it by hand, record which count you divided by. If your figure comes out lower than Studio's, check whether you used views where Studio used engaged views. For Shorts, always divide by engaged views; our Shorts pay worksheet explains why the public counter misleads.
RPM-to-CPM reconciliation worksheet
Export one date range for long-form videos only, using Advanced mode, which YouTube's Analytics help says lets you see expanded reports and export data. Shorts stay out on purpose: their revenue comes from a pooled feed rather than ads on your Short, so a bridge from CPM to RPM does not describe them. Fill lines 1 to 9 from the export, then calculate the rest.
| Line | Metric or calculation | What it tells you | Your figure |
|---|---|---|---|
| 1 | Views | Plays in the range | |
| 2 | Engaged views, if your export includes them | The count Studio's RPM may be using | |
| 3 | Estimated monetized playbacks | Plays that showed at least one ad | |
| 4 | Ad impressions | Individual ads shown | |
| 5 | CPM | Advertiser cost per 1,000 impressions | |
| 6 | Playback-based CPM | Advertiser cost per 1,000 monetized playbacks | |
| 7 | Estimated ad revenue | Your revenue from ads alone | |
| 8 | Estimated revenue | Your revenue from all YouTube sources | |
| 9 | RPM as shown in Studio | The figure you are reconciling to | |
| 10 | Advertiser spend: line 5 × line 4 ÷ 1,000 | Gross spend implied by impression pricing | |
| 11 | Cross-check: line 6 × line 3 ÷ 1,000 | Should land close to line 10; a large gap means mismatched ranges or filters | |
| 12 | Ad-enabled share: line 3 ÷ line 1 | How many plays carried ads | |
| 13 | Ad load: line 4 ÷ line 3 | Ads per monetized playback | |
| 14 | Observed share: line 7 ÷ line 10 | What reached you per unit of advertiser spend | |
| 15 | Ad part of RPM: line 7 ÷ line 1 × 1,000 | What ads contribute per 1,000 views | |
| 16 | Non-ad part: (line 8 − line 7) ÷ line 1 × 1,000 | Premium, memberships and Supers per 1,000 views | |
| 17 | Rebuilt RPM: line 15 + line 16 | Compare with line 9 |
Read the finished sheet as a chain. CPM multiplied by ad impressions per view gives advertiser spend per 1,000 views; your observed share turns that into ad revenue per 1,000 views; adding the non-ad part gives RPM. When RPM moves, the line that moved names the cause: a change in line 12 or 13 is about ad delivery, a change in line 5 is advertiser pricing, and a change in line 16 is your fans and Premium viewers.
You can test lines 10 and 11 on YouTube's own numbers before you trust them with yours. In the example on the ad revenue analytics page, a $3.50 CPM across 2,000 impressions and a $4.67 playback-based CPM across 1,500 monetized playbacks both come back to roughly the $7 of advertiser spend the example started with. If your own two lines disagree by much more than rounding, the export almost certainly mixes date ranges, formats or filters.
Choose the range with care. Whole calendar months are easiest to compare, and waiting until finalized earnings have reached Analytics, which YouTube's Analytics help puts at typically the 7th to 12th of the following month, keeps estimates out of the revenue lines. Avoid a range that straddles the view-counting change of August 24, 2026 described on the engagement metrics page, unless you use engaged views on both sides of it.
Do not expect line 14 to match the 55% Watch Page share in YouTube's earnings overview. YouTube's comparison table counts Premium inside CPM, the revenue help page says Watch Page ad revenue leaves out partner-sold ads, and estimates are adjusted for invalid traffic and claims. The gap tells you something about your revenue mix; it is not proof of an error. If line 17 misses line 9, rerun lines 15 and 16 with line 2 in place of line 1.
Where each number lives in Studio
RPM appears in the Revenue tab's content performance report, which YouTube's revenue help page says ranks your highest-earning content by format and includes RPM. Estimated revenue, the all-sources total, sits on the Revenue tab, while estimated ad revenue sits in the revenue sources report, per the ad revenue analytics page. If CPM, playback-based CPM, ad impressions or monetized playbacks are not on your default cards, look for them in Advanced mode. Revenue takes 2 days to show in Analytics, according to the revenue help page, so leave a gap before exporting a recent range.
Keep long-form and Shorts in separate exports. Shorts RPM is per 1,000 engaged views drawn from a pool, as our Shorts monetization explainer sets out, and blending it with long-form views produces an RPM that describes neither format.
What neither metric covers
RPM leaves out revenue from merchandise and the merch shelf, brand deals and sponsorships other than YouTube Creator Partnerships, and income earned indirectly through YouTube, such as services, speaking or consulting, according to YouTube's RPM help. CPM tells you what advertisers paid, which YouTube itself says is not what you earn. Neither number sets a sponsorship fee, because a brand is buying your audience's attention and your production time, not ad inventory; price deals with the UGC creator rates worksheet and present your channel with the influencer media kit template.
To turn RPM into an income estimate, use our per-video estimate worksheet for long-form views or the monthly YouTube money calculator for the whole channel.
Limitations
The worksheet depends on which metrics your export includes, and YouTube renames and redefines them; the conflicting card description above is one example, and the redesigned Studio rolling out since July 2026, noted in YouTube's Analytics help, may move them again. Rounding in exported figures will leave small gaps between rebuilt and reported values.
Channels with few monetized playbacks will see noisy ratios, so reconcile over a longer range when your numbers are small. And the analysis explains revenue you have already earned; it cannot set future prices, which advertisers drive through their bids, or say how your income will be taxed, which is a question for a registered tax agent or accountant.
