A podcast ad is priced per thousand downloads, and in 2026 the realistic range for an independently sold host-read mid-roll is roughly $25 to $35 per thousand. Pre-produced and programmatic spots sit lower; a well-defined business or finance audience can go a long way higher.
That is the short answer. The longer one is more useful, because the single number everyone asks for — “what’s a good CPM?” — hides the thing that actually determines what your show earns.
What CPM actually means
CPM is cost per mille: the price an advertiser pays for one thousand downloads of one ad slot. It is not the price of the episode, and it is not the price of the whole campaign.
The arithmetic for a single slot on a single episode is:
revenue = (downloads ÷ 1,000) × CPMSo a show averaging 5,000 downloads per episode, selling one mid-roll at a $25 CPM:
5,000 ÷ 1,000 × $25 = $125 per episodePublish four episodes a month and that one slot is $500 a month. Sell a pre-roll alongside it at $18 and you add $90 an episode, or $360 a month. The numbers get interesting quickly, but only when you multiply across slots and episodes — never from a single spot.
CPM ranges by format and slot
Published rate guidance clusters in a fairly consistent band. Acast and industry rate guides put pre-recorded and programmatic spots broadly in the $15–$30 range, and host-read sponsorships at $25–$40, with business, finance and B2B shows going above that. Independently sold host-read mid-rolls tend to land around $25–$35 in our experience — treat that as a practical midpoint rather than a surveyed market average.
| Slot / format | Typical CPM band | Why it prices there |
|---|---|---|
| Pre-roll (pre-produced) | ~$15–$25 | Full reach, but zero listener commitment at second zero |
| Mid-roll (pre-produced) | ~$20–$30 | Engaged audience, but no host endorsement |
| Mid-roll (host-read) | ~$25–$40 | The premium unit — commitment plus endorsement |
| Post-roll | ~$10–$18 | Smallest audience; many listeners stop at the end of content |
| Programmatic / remnant | ~$5–$18 | Sold by machine into unsold inventory, priced accordingly |
Treat these as orientation, not a rate card. Published ranges are gathered from sellers with an interest in the number looking healthy, and the spread inside any one row is wider than the gap between rows.
Category matters more than size
This is the part most rate guides bury, and it is the most actionable thing on this page.
Rate surveys consistently show business and finance shows at the top of the range — commonly quoted around $25 to $55 — while kids and family shows sit at the bottom, often $12 to $25. That is a two-to-four-times spread driven entirely by who is listening, not how many.
The logic is straightforward once you look at it from the buyer’s side. An advertiser is not buying attention in the abstract; they are buying access to people who can plausibly buy the thing. A B2B SaaS company selling a $2,000-a-month product needs a handful of qualified buyers to justify a campaign. A thousand listeners who all run engineering teams are worth more to them than a hundred thousand listeners drawn from the general public, because the general public cannot purchase the product at any price.
This is why “grow the audience” is often the wrong first move for a show trying to monetize. Sharpening who the audience is frequently pays better than adding listeners who dilute it.
Worked examples at three sizes
Assume one pre-roll at $18 and one mid-roll at $28, four new episodes a month, all slots sold.
500 downloads per episode
pre-roll: 500 ÷ 1,000 × $18 = $9
mid-roll: 500 ÷ 1,000 × $28 = $14
per episode: $23 → 4 episodes = $92/monthAt this size, CPM pricing is not the right instrument. A single flat-rate sponsorship would beat this comfortably.
5,000 downloads per episode
pre-roll: 5,000 ÷ 1,000 × $18 = $90
mid-roll: 5,000 ÷ 1,000 × $28 = $140
per episode: $230 → 4 episodes = $920/monthNow CPM pricing works, and the show is a real revenue line.
50,000 downloads per episode
pre-roll: 50,000 ÷ 1,000 × $18 = $900
mid-roll: 50,000 ÷ 1,000 × $28 = $1,400
per episode: $2,300 → 4 episodes = $9,200/monthAt this level you would typically run two mid-rolls and work with an agency or marketplace, so the real figure is higher — and the operational overhead is a job.
The number everyone forgets: the back catalogue
Every example above counts only new episodes. That is how almost all podcast revenue estimates are built, and it systematically understates what an established show is worth.
An episode you published eighteen months ago is still being downloaded. If it is any good and the topic is evergreen, it may be downloaded for years. Those downloads are ad inventory in exactly the same sense that this week’s episode is — the only question is whether the ad sitting in them can be changed.
If your ads are baked into the audio, they cannot. That old episode is either running no ad at all, or running a promo code that expired in 2024, which is worse than nothing because it makes the show look abandoned. With dynamic ad insertion, one change applies across every episode you have ever published, and the archive becomes a second revenue line that grows every time you publish.
A show with 80 back-catalogue episodes collectively pulling 20,000 downloads a month, running a single $25 mid-roll:
20,000 ÷ 1,000 × $25 = $500/monthThat is $500 a month from work you already did. It is also the single strongest argument for dynamic insertion, and it is covered properly in how to monetize your podcast back catalogue.
What actually moves your rate
In rough order of leverage:
- Category. The largest single factor and the hardest to change quickly.
- How specifically you can describe your audience. “Mostly men, 25–45” is worth less than “roughly 60% work in-house at agencies; a third are decision-makers on tooling budgets.”
- Host-read vs. pre-produced. Reading it yourself, in your own words, is worth a real premium and costs you nothing but a take.
- Direct vs. marketplace. Selling direct removes the intermediary’s cut, at the cost of doing the selling.
- Proof it works. A sponsor who can see attributable signups will renew at a higher rate. Vanity numbers will not survive their second campaign.
Notice that download count is not in the top three. It is the number podcasters obsess over and roughly the fourth most important thing about the deal.
