Podcast Ad Rate Calculator
Free podcast advertising rate calculator: estimated ad price per episode from downloads, CPM and number of ad spots.
What does the Podcast Ad Rate Calculator do?
It estimates the advertising value of a podcast episode from the average downloads, a CPM and the number of ad spots, so you can price a single episode or a campaign.
- Inputs: downloads per episode, CPM, ad spots per episode.
- Output: rate per spot and total per episode.
- Method: downloads per thousand times the CPM, multiplied by the number of spots.
Quick answer
5,000 downloads an episode at a CPM of 18 gives 90 per spot, or 180 for a two-spot episode. A host-read endorsement can command a CPM of 30 or more, well above programmatic rates.
What This Calculator Really Does
Podcast advertising is priced on reach, measured as downloads or listens, at a cost per thousand, or CPM. Multiply the downloads by the CPM, scaled per thousand, and you have the value of a single spot. A typical episode carries two or three spots, so the total is that figure times the number of spots. The one nuance the calculator highlights is that not all spots are equal: a host-read endorsement, where the presenter talks about the product naturally, sells for a materially higher CPM than an automatically inserted programmatic ad, because audiences trust the host.
The rules it applies
- Rate per spot: downloads divided by 1,000, multiplied by the CPM.
- Per episode: rate per spot multiplied by the number of spots.
- Benchmarks: programmatic CPMs from about 15, host-read from about 30 upward.
- Not modelled: listener demographics, the age of the episode, and the premium for a mid-roll over a pre-roll.
Worked example with real numbers
5,000 downloads an episode at an 18 CPM: 5,000 divided by 1,000 is 5, and 5 times 18 is 90 per spot. With two spots the episode earns 180, and a 20-episode series priced at the same rate is 3,600. If the host reads the ad instead of a programmatic insert, a 30 CPM would lift each spot to 150 and the episode to 300.
Reading the result
The formula is a fair starting point, but podcast pricing rewards two things above all: a specific, valuable audience and a host the listeners trust. A niche show with 3,000 committed listeners in a high-value field can charge more than a general show with ten times the downloads, because advertisers pay for the right ears, not the most ears. Sell multi-episode campaigns rather than single insertion orders, and remember that your back catalogue keeps earning, so a package of catalogue spots is often the most valuable inventory you own. Track which episodes convert for sponsors; proven performance is what justifies a rate above the CPM benchmark.
