CPMCost Per Mille
CPM stands for Cost Per Mille — literally "cost per thousand" in Latin. On YouTube it represents the rate advertisers bid per 1,000 ad impressions on your videos. CPM is gross: it is the money the advertiser spends, not the money the creator receives. The creator share is called RPM.
CPM (Cost Per Mille) is the amount advertisers pay per 1,000 ad impressions on a YouTube video, measured before YouTube takes its 45% cut.
Why CPM matters for YouTube creators
CPM is the upstream signal that drives every creator's ad income. Two creators can have identical view counts and wildly different earnings because their CPMs differ by 5-10x depending on niche, audience country, season, and ad format. Finance, tech, and B2B content typically command CPMs of $15-40 USD, while gaming, kids, and vlog content often sit between $2-6 USD. Understanding your CPM tells you whether to chase more views, pivot the niche, or invest in advertiser-friendly content formats. CPM also has strong seasonal swings: Q4 (October–December) CPMs are 50-100% higher than Q1 because of holiday ad spend.
How CPM works
YouTube auctions ad inventory in real time. Advertisers bid for the right to show their ad before, during, or after a video. The winning bid divided by 1,000 impressions becomes the CPM. Skippable ads, non-skippable ads, and bumper ads each have separate CPM markets. CPM is recorded in YouTube Studio's Revenue tab and only includes monetized playbacks — views with no ad shown are excluded.
CPM in practice
A finance channel in the United States sees an average CPM of $24 USD during Q4 — its 1M monthly views generate roughly $24,000 in gross ad spend, of which ~$13,200 ends up in the creator's pocket as RPM.
A gaming channel in Brazil with the same 1M views earns far less because its CPM averages $1.80 — both lower bid demand and Brazil's lower regional rates compound the gap.
