Quick answer
A $25 CPM converts to a $13.75 RPM at YouTube's 55% creator share — and at 8,500 views a day that is about $117 a day, or $3,506 a month. Real RPM lands lower, because not every view shows an ad. Use RPM for income decisions; CPM only measures advertiser demand.
How the YouTube CPM / RPM Calculator works, step by step
The calculator works in two directions: enter a CPM to see the RPM it implies, or enter your RPM from YouTube Studio to see the CPM it implies. Add your daily views and it returns daily, monthly and yearly earnings, plus earnings per 10,000 views — the figure that makes one video's value easy to judge. At the defaults — a $25 CPM and 8,500 views a day — the implied RPM is $13.75, daily earnings about $117, monthly about $3,506 and yearly about $42,659.
The conversion applies YouTube's standard 55% creator share for long-form video: RPM equals CPM multiplied by 0.55. That is an upper bound, not a promise. CPM counts ad impressions; RPM counts views, and a video can carry several ad impressions per view while many viewers see no ad at all.
The gap between 55% of CPM and real RPM is the unmonetized-view effect: YouTube Premium views (paid from a subscription pool instead), ad-blocked views, and views in regions or on content where ads do not run. A monetized-view share of 70 to 85% is typical, so a channel whose CPM implies a $13.75 RPM often banks closer to $10.
The niche chart shows typical advertiser CPMs for US-heavy audiences: finance and investing at $42, business and SaaS at $36, tech reviews at $26, education at $20, health and fitness at $18, gaming at $11, entertainment at $9, vlogs and lifestyle at $8, and music at $7. Viewer country moves these figures more than channel size does.
For Shorts, neither figure maps directly: Shorts revenue comes from a pooled model with a 45% creator share allocated by view share, and is best tracked as its own RPM in Studio. Videos over 8 minutes can carry mid-roll ads, which raise ad impressions per view — one of the few levers a creator has on the CPM side of the equation.
The formula
RPM (upper bound) = CPM x 55%. Implied CPM = RPM / 55%. Estimated earnings = views / 1,000 x RPM. Actual RPM = revenue / views x 1,000, measured in YouTube Studio.
Worked example — try it on the calculator above
Worked example: $24 CPM channel, 800,000 views
Upper-bound RPM: $24 x 55% = $13.20, implying earnings of 800 x $13.20 = $10,560. The channel's Studio shows actual revenue of $8,000, so actual RPM is $8,000 / 800 = $10.00. The $3.20 gap is the unmonetized-view effect: roughly a quarter of views carried no paid ad. Planning a hire against the $10,560 figure would overcommit by $2,560 a month. The same channel posting a video that reaches 10,000 views earns $137.50 at the upper-bound RPM and $100 at the actual RPM — the per-video figure the calculator reports, and the one that makes a single video's value easy to judge. The finance niche in the calculator's chart, at a $42 CPM, implies a $23.10 RPM — and a music channel at a $7 CPM implies just $3.85.
Frequently Asked Questions
What CPM do advertisers pay on YouTube?
Broadly $5 to $15 for general entertainment audiences in English-speaking markets, $15 to $30 for tech, education and business, and $30 to $50 or more for finance, insurance, legal and high-value B2B topics. CPMs are auction prices: they rise in the fourth quarter, fall in January, and vary by viewer country more than by channel size.
Why is my RPM less than 55% of my CPM?
Because the denominators differ. CPM divides ad revenue by ad impressions; RPM divides your revenue by all views, including views with no ad — YouTube Premium views (paid from a subscription pool instead), ad-blocked views, and views in regions or on content where ads do not run. A monetized-view share of 70 to 85% is typical.
Does a higher CPM mean a better channel?
It means a more valuable audience to advertisers, not a bigger income. Income is views multiplied by RPM, and a low-CPM channel with ten times the views out-earns a high-CPM niche channel. CPM matters when choosing topics at the margin — among video ideas with similar view potential, pick the one advertisers pay more for.
How do I raise my RPM?
Shift topic mix toward advertiser-valued subjects, lengthen videos past 8 minutes to allow mid-roll ads, and build audience share in high-CPM countries. Also check for limited-ad flags on individual videos — a video marked as showing limited or no ads earns near zero regardless of its CPM niche.
