What is CPM (Cost Per Mille)?
CPM stands for cost per mille — Latin for thousand — and represents the price paid for 1,000 impressions of an ad. It is the dominant pricing model for display ads, YouTube pre-rolls, podcast sponsorships, and newsletter ads. CPM is a reach metric: it tells you what a thousand eyeballs cost, not whether those eyeballs converted. For creators, CPM is critical because it is the foundation of most ad-share revenue (YouTube AdSense, podcast networks, newsletter sponsorships). Typical CPMs vary wildly: YouTube AdSense $1–$15 depending on niche, podcast host-read $20–$50, premium newsletters $50–$200, B2B SaaS audiences can reach $300+.
Why it matters for creators
CPM matters because it is how reach is priced. If you can predict your CPM, you can model your sponsorship and ad revenue from impressions alone. For brands, CPM is the headline number compared across channels, but smart brands also pair it with CTR and conversion to compute true cost per acquisition.
How it works
- 1CPM = (Total ad spend / Total impressions) x 1,000.
- 2An advertiser pays a flat rate per thousand views, regardless of clicks or sales.
- 3Creators sell ad inventory at a CPM based on audience size and niche.
- 4Platforms (YouTube, Spotify) split ad revenue with creators based on programmatic CPM.
Examples
- A $500 newsletter ad to 25,000 subscribers = $20 CPM.
- A YouTube channel earning $4,000 from 1M ad views = $4 CPM.
- A podcast charging $1,500 for a 30k-download episode = $50 CPM.
Common mistakes
- Quoting CPM without specifying impressions vs unique reach.
- Comparing CPM across channels with very different intent (display vs host-read).
- Ignoring CTR and conversion — high CPM with high conversion can be cheaper than low CPM with no conversion.
