Podcast Ad Insertion Revenue Formula

Revenue is calculated per placement type using CPM rates applied to average downloads per episode across all monthly episodes.

Ad Revenue per Episode = (Average Downloads / 1,000) × CPM Rate
Pre-roll Revenue = (Downloads / 1,000) × Pre-roll CPM
Mid-roll Revenue = (Downloads / 1,000) × Mid-roll CPM
Post-roll Revenue = (Downloads / 1,000) × Post-roll CPM
Monthly Revenue = (Pre + Mid + Post Roll Revenue) × Episodes per Month

Mid-roll ads command the highest CPMs ($25–$50) due to superior listener engagement. Host-read ads earn a 30–50% premium over pre-produced spots. Premium niches (B2B, Finance, Tech) command $40–$70+ CPMs.
