Newsletter vs Podcast Sponsorship Calculator
Honest CPM math for the two formats sponsors actually buy. See per-placement and per-month revenue for both.
Newsletter
Realistic: 30–45% for engaged niche newsletters.
Consumer: $15–$30. B2B: $40–$120.
Max 1 per send to keep reader trust.
Podcast
Host-read mid-roll: $25–$50 consumer, $50–$150 B2B.
Typical: pre-roll + mid-roll = 2.

If you run both, fill rate (% slots sold) is the real swing — assume 60–80% in year one.
Below ~$200/slot, you're better off doubling audience than chasing higher CPMs. Sponsors hesitate at small volumes regardless of price.
These CPMs sit in the documented consumer/B2B range from operators like Tinyletter, Beehiiv, and Acast.
- Newsletter revenue = (subscribers × open rate / 1,000) × CPM × placements
- Podcast revenue = (downloads / 1,000) × CPM × ad slots × episodes
- Ad slot = one host-read placement (pre-roll, mid-roll, or post-roll)
Common questions
Why do podcasts usually command higher CPMs?▾
Host-read podcast ads convert because the audience is captive (driving, walking, working out) and attribution via promo codes is clean. Newsletter sponsors pay for click-through, which is measurable but lower-intent. Typical: podcast $25–$50 CPM, newsletter $15–$40 CPM, both higher in B2B.
What's a 'CPM' on a newsletter or podcast?▾
Cost per 1,000 'impressions' — for newsletters that's opens (or sometimes subscribers), for podcasts that's downloads per episode. Always confirm which metric the sponsor is buying.
Do I need huge numbers to charge real money?▾
No. A 5K B2B newsletter or a 2K-download niche podcast can charge $300–$800 per placement if the audience is targeted. CPMs in narrow B2B categories often hit $80–$150.
What about long-term value to the sponsor?▾
Podcasts compound — old episodes keep getting downloaded for years, often included in the deal. Newsletter sponsorships are one-and-done. Price accordingly: a podcast slot is worth ~1.3× the newsletter equivalent for the same audience.
