Podcast Sponsor CPM & Earnings Estimator

Downloads times CPM, multiplied across paid reads and episodes

18,000 downloads per episode at a $25 CPM per paid read works out to $450 per read (18,000 / 1,000 x $25). With 2 paid reads per episode across 4 episodes/month, gross sponsor revenue is $3,600. After a 15% agency commission ($540), monthly net is $3,060.

Every one of the four multipliers here (downloads, CPM, reads per episode, episodes per month) scales gross revenue proportionally -- doubling reads per episode from 2 to 4 doubles gross revenue to $7,200 just as directly as doubling downloads would, which makes this a useful lever-testing tool for negotiating ad load versus per-episode revenue.

The agency commission (15%) only applies if sponsorships are sold through a podcast ad network or agency -- creators who sell sponsorships directly to brands keep the full gross figure, making direct sales worth roughly 17.6% more net revenue at the same gross ($3,600 vs. $3,060) for the added effort of self-selling.

Why download count is the number that actually matters

Downloads times CPM / 1000. Agency commission is a toggle percent. CPM-based podcast sponsorship pricing is built entirely around downloads within a defined window (commonly 7 or 30 days post-release), not total lifetime downloads or subscriber count -- a show with a large back catalog but modest per-episode fresh downloads prices lower than the catalog size might suggest.

CPM itself varies significantly by niche (business and tech podcasts often command higher CPMs than general entertainment) and by ad placement (pre-roll, mid-roll, and post-roll typically carry different rates, though this model uses one flat CPM for simplicity).

This assumes downloads stay flat across the 4 episodes -- a show with declining or growing per-episode downloads over the month would see gross revenue shift accordingly, episode by episode.

If episode length itself needs adjusting to fit more ad reads without hurting completion rate, the Podcast Episode Length Optimizer is the tool for that trade-off.
