What is CPM (Cost Per Mille)?
CPM stands for Cost Per Mille, which means cost per thousand downloads. It is the rate advertisers pay for every 1,000 downloads of your podcast episode.
Why CPM (Cost Per Mille) Matters for Podcasters
CPM is the foundation of podcast monetization. When an advertiser agrees to pay $20 CPM, they're committing to pay $20 for every 1,000 downloads your episode receives. This rate varies significantly based on your podcast's category, audience demographics, and ad placement. Business and technology podcasts often command higher CPMs ($25-$40) because their audiences are typically more valuable to B2B advertisers. True crime and entertainment shows might see lower CPMs ($10-$20) but can make up for it with higher download volumes. Mid-roll ads typically command the highest CPMs because listeners are most engaged during the middle of an episode. Pre-roll ads come next, while post-roll ads usually have the lowest rates since some listeners skip the end. Understanding your CPM helps you price sponsorships accurately and forecast revenue based on your download numbers.
