Comparing YouTube RPM across two date ranges can reveal whether a channel is earning more or less revenue per thousand views. The comparison only helps when the date ranges, video formats, revenue definitions, and denominators are consistent. A change in RPM is not the same thing as a change in total earnings.
Quick answer: For each period, divide eligible reported creator revenue by the relevant view count and multiply by 1,000. Compare the two RPM values, then inspect revenue sources and viewing activity before drawing conclusions. YouTube’s reported RPM is usually the best starting point when both periods are available in Analytics.
What Does Comparing YouTube RPM Tell You?
RPM means revenue per mille, or creator revenue per 1,000 views. YouTube’s RPM considers revenue after applicable revenue sharing and can reflect multiple YouTube revenue sources. It is not the same as the advertiser-facing CPM metric. For ordinary videos, the RPM denominator uses views; for Shorts, YouTube uses engaged views. Those differences are important when making a comparison.
Use the Same Revenue Definition
If the first period includes channel memberships, Super Chat, or other eligible reported revenue, do not compare it with an ad-only revenue number for the second period. A revenue mix change can move RPM even if the underlying ad performance stays similar. Use the same Analytics metric and reporting scope on both sides.
Keep the Viewing Denominator Consistent
Views from regular videos and engaged views from Shorts are not interchangeable. Separate formats before attributing a change to advertising demand. If the channel has gained more Shorts views, its overall revenue rate may change partly because the composition of viewing changed, not simply because advertisers paid differently.
How to Calculate YouTube RPM for Two Periods
For regular video reporting, the simplified formula is RPM = (creator revenue ÷ video views) × 1,000. Use the reported figures from each period, and avoid rounding before the final step. If the view denominator is zero, RPM is undefined and should be shown as N/A.
Worked Example With Two Date Ranges
Consider the entirely hypothetical figures below. These are examples of arithmetic, not measured channel results, industry averages, or expected YouTube payouts.
| Metric | Period A | Period B |
|---|---|---|
| Creator revenue | $200 | $330 |
| Relevant views | 100,000 | 150,000 |
| Calculated RPM | $2.00 | $2.20 |
| Revenue change | +$130, or +65% | |
| RPM change | +$0.20, or +10% | |
Period A RPM equals $200 ÷ 100,000 × 1,000, or $2.00. Period B equals $330 ÷ 150,000 × 1,000, or $2.20. RPM increased by 10%, while revenue increased by 65%. The differences tell distinct stories: a higher volume of views contributed heavily to the revenue increase, while revenue per thousand views improved more modestly.
Calculate the Percentage Change
Use RPM change (%) = ((new RPM − old RPM) ÷ old RPM) × 100, provided the old RPM is not zero. For $2.00 and $2.20, the increase is ($2.20 − $2.00) ÷ $2.00 × 100 = 10%. When the baseline RPM is zero, do not invent an infinite growth percentage; state the absolute difference instead.
How to Compare the Periods in YouTube Studio
- Open YouTube Studio and select Analytics.
- Open Revenue, where available for your channel and monetization eligibility.
- Choose the first date range and record the displayed RPM, views, and estimated revenue for the same content scope.
- Choose the second date range and capture the equivalent metrics.
- Compare similar calendar lengths, or document why unequal lengths are being used.
- Break results out by video format and revenue source if the available reporting views support that analysis.
Interface wording and available reports may change. If Analytics provides an explicit date comparison, you can use it; otherwise, record both ranges separately. Estimated revenue can later be adjusted, so avoid treating an early or incomplete reporting period as finalized income.
Why RPM Can Change Without an Equivalent Revenue Change
More Non-Monetized Views
Additional video views that do not generate revenue can reduce overall RPM, even when gross viewing activity increases. That does not necessarily mean that the channel is earning less money in total. Check the revenue amount alongside the denominator.
Different Audience or Revenue Mix
Viewer geography, time of year, available advertising, video length, monetization eligibility, and revenue sources can affect reported figures. They are potential explanations, not proof of what caused a specific channel’s movement. Use video-level or source-level Analytics data to test plausible explanations.
Small Sample Sizes
A short period with only a small number of views can produce a volatile RPM. A few transactions or membership events may disproportionately affect results. Consider a longer comparable period and identify outlier videos before changing a content strategy.
RPM Comparison Checklist
| Check | Why it matters |
|---|---|
| Same video format | Shorts and regular video denominators differ |
| Same revenue definition | Ad-only and broader creator revenue are not equivalent |
| Comparable reporting dates | Incomplete days may distort results |
| Sufficient view volume | Small samples are more volatile |
| Revenue alongside RPM | Rate changes and income changes answer different questions |
Estimate Revenue From an Observed RPM
When you know your own applicable RPM, an illustrative estimate is revenue = views ÷ 1,000 × RPM. For example, 75,000 regular video views at a $2.20 RPM imply $165 under the stated assumption. That is a scenario calculation rather than a guarantee that a future month will match the same rate. The YouTube Earnings Calculator can perform this arithmetic with your own inputs.
Questions About Comparing YouTube RPM Periods
Should I Compare RPM or CPM?
Use RPM to compare creator revenue per thousand relevant views. Use CPM to understand advertiser-side pricing for advertising impressions. Do not substitute one for the other.
Should I Compare Two Months of Different Lengths?
RPM is a normalized rate, so different lengths do not automatically invalidate a comparison. Still, uneven weekdays, seasonality, incomplete reporting, and changes in video mix can make an interpretation misleading. Show the chosen periods explicitly.
What if My RPM Declined but Revenue Increased?
That can happen when views grow faster than creator revenue. Review both absolute revenue and the viewing denominator, not RPM in isolation.
Sources for Comparing YouTube RPM Across Date Ranges
The calculations here use standard ratios and hypothetical figures. YouTube’s own explanations distinguish RPM from CPM and describe what RPM includes. See YouTube Help: Understand ad revenue analytics and YouTube Help: Check your YouTube revenue. Neither source supports a universal RPM assumption for individual channels.
