The Basics
How the Podcast CPM Calculator Works
Podcast ads are sold per 1,000 downloads. Divide the sponsorship price by the downloads of the episode and multiply by 1,000. A $500 slot on 20,000 downloads is a $25 CPM. Compare slots by CPM, since longer reads and loyal audiences often justify a higher rate.
