Podcast Advertising Rates: What Ads and Sponsorships Cost

Podcast advertising can put a brand in front of listeners who chose a show because they care about its subject. For a B2B company, that can mean reaching operations leaders on a logistics show or finance teams on an accounting one. The difficulty is the price. Rates are quoted in different units, the same spot can be sold several ways, and a show's audience figures need checking before you trust them.

This guide explains how podcast ads are priced and what the providers that publish their rates charge. It works through the cost of a small campaign, sets out what moves the price and the main ways to buy, and explains what a "download" actually measures. It ends with how to vet a show and the questions to settle before you sign, including when a B2B company is better served by its own show.

What podcast ads cost

Most podcast ads are quoted as a CPM, a price per thousand downloads or delivered ads, depending on the purchase. Libsyn Ads, the podcast ad marketplace that AdvertiseCast's old web address now leads to, explains it on its undated rate page (opens in a new tab): the price "comes down to the amount of downloads/impressions the podcast receives in the first 30 days and the CPM rate".

The formula is cost = billable count × CPM ÷ 1,000. Libsyn's advertiser page adds that there is no strict industry standard, but most rates are charged on a show's average downloads per episode within 30 days of publication.

Of the ad sellers whose pages were read for this guide, two publish rate figures, and their ranges overlap.

The baked-in rates above use Libsyn's length-specific averages. Its broader ad-unit table lists $24 to $26 for a baked-in read of either 30 or 60 seconds, so confirm the rate in your quote.

Libsyn's advertiser page (opens in a new tab) puts a typical 30-second spot anywhere from $10 to $50 CPM, with shorter 10 or 15-second spots cheaper and 60-second spots more expensive.

Business audiences cost more. Libsyn's host-read average for business shows is $30, its highest category. Acast's pricing guide (opens in a new tab) says business, finance and B2B podcasts "regularly command $40+ CPMs", and gives $15 to $30 for pre-recorded network ads and $25 to $40 for host-read sponsorships as its 2026 planning benchmark.

The market behind these prices is still growing. The IAB/PwC revenue report (opens in a new tab) put US podcast advertising at $2.9 billion in 2025, up 17.6% on 2024, and The Infinite Dial 2026 (opens in a new tab) from Edison Research found that 58% of Americans aged 12 and over, about 167 million people, had consumed a podcast in the past month.

What a small campaign costs: a worked example

Take a hypothetical business podcast that averages 5,000 downloads per episode in its first 30 days. A host read at Libsyn's business-category average of $30 CPM costs 5,000 × $30 ÷ 1,000, or $150 an episode. Eight episodes cost $1,200. At $40, the level Acast describes for B2B shows, the same eight episodes cost $1,600.

Illustrative scenario from the article; figures are assumptions, not market benchmarks.

This assumes one spot per episode and covers airtime only. Acast's guide lists ad production and attribution or reporting as costs beyond the CPM, so ask what a quote includes and whether a minimum purchase applies.

Use the count and window the seller will bill against. For a host read on one show, that is usually average downloads per episode over the first 30 days; for an inserted or programmatic campaign, it may be the contracted number of delivered ads or impressions. Multiply that count by the CPM and divide by 1,000. If a show quotes a flat price per episode instead, divide that price by its downloads and multiply by 1,000 to get the CPM it implies, so you can compare it with other offers.

What moves the price

The published ranges are averages. Six things decide where a particular quote lands. Two terms recur: ads run before an episode (pre-roll), during it (mid-roll) or at the end (post-roll), and a baked-in ad stays in its episode for good, while a dynamically inserted ad is placed by the seller and can run in new or older episodes.

• Who reads it. Acast's benchmark for host-read sponsorships is higher than for pre-recorded network ads, though the ranges overlap. Libsyn's dynamic units can be host-read or pre-produced at the same rate.
• Where it runs. Acast's guide says mid-roll carries a premium over pre-roll and post-roll, and calls post-roll the lowest-value slot.
• How long it is. Libsyn prices 30-second spots below 60-second spots, and 10 or 15-second spots lower again.
• Who listens. Business and B2B audiences sit at or above the top of both providers' ranges.
• How narrowly you target. On Acast's self-serve platform, targeting below country level (regions, cities, postal codes) raises the CPM by 20% (opens in a new tab), and categories, shows, age and other filters can raise it too.
• How much you commit. Libsyn notes that some podcasts offer volume discounts for longer relationships, and recommends repeating a message over 4, 8 or 12 episodes.

Back-catalog ads cost less

A show's older episodes keep being played. Libsyn says some shows get 30% or more of their downloads from episodes older than 30 days, and its rate for dynamic ads across a whole back catalog is $14 to $16, against $18 to $22 for the same dynamic ad in a new episode. If a show in your field covers evergreen subjects, sponsoring its back catalog can be the cheaper way in. On a show about a fast-moving technology, last year's episodes may no longer be what your buyers want to hear.

Four ways to buy podcast ads

How you buy decides how much control you have over where the ad runs. The four routes below can be combined.

Spotify's podcast ads page (opens in a new tab) shows the split. It sells podcast ads through its self-serve Ads Manager, direct orders and a programmatic exchange, while "custom podcast sponsorships (such as host-read ads)" go through a Spotify representative. Ads Manager (opens in a new tab) starts at a budget of 250 in your local currency, across music, podcasts or both. Acast's help center suggests starting a niche self-serve campaign at around €1,000 and a broader one at €2,500 or more.

What a podcast sponsorship costs

A sponsorship is a negotiated package. It can name the brand with the show ("the XYZ podcast, powered by Acme"), in its show notes and promotion, and in the host's reads. No whole-show package price appeared on the pages read; Acast's host-read sponsorship benchmark in the rate table prices the audio ads only. Ask for separate prices for the audio ads, the naming, the show-note placements and any promotion. Work out a CPM for the audio ads from the agreed count, compare it with the published rates, and judge the other elements on their own.

You can also negotiate other arrangements with a show: an affiliate commission tracked through a link or code, a paid guest appearance, or product placement in video episodes. A paid guest and topic need to fit the show, or its audience will notice.

What a download measures

Every CPM above is priced on downloads or on delivered ads, so the definitions set what you are paying for. The IAB Tech Lab's Podcast Technical Measurement Guidelines (opens in a new tab), version 2.3, count a valid download when enough of the file to play for one minute has been downloaded, or the whole file for an episode shorter than that. An ad counts as delivered only inside a valid download, and a dynamically inserted ad only once all of it has been downloaded. Both counts come from filtered server logs and show delivery to a device, not playback. The Tech Lab's own explanation of version 2.3 (opens in a new tab), published in September 2026, is direct: "A download is not the same thing as a confirmed play."

That gap is why the source of a show's numbers matters. When we built the ads product that became Listen Network, the aim was to grow real downloads. As I said on the Leaders of B2B episode "Driving ROI Through B2B Podcasts" (opens in a new tab) in December 2024, there was a lot of questionable activity in podcast downloads, including incentivized traffic from mobile games. Before I paid a CPM to any show, I'd want to know which hosting platform counts its downloads, whether that platform follows the IAB guidelines, and how much of the audience the show has paid to acquire.

Measurement after the campaign deserves the same care; the guide to B2B podcast KPIs covers what to track. A promo code or a dedicated web address records direct response; Acast's guide says pixel tracking lets you monitor website visits, conversions and cost per acquisition. It also says such tracking usually costs extra and that Acast includes it through its attribution partner, Podscribe. In B2B, neither will show every deal the ad influenced. Data can guide a decision, but some of a long sale happens in conversations nobody tracks, so agree before launch what result would justify a second flight.

How to choose shows

Fit decides whether any of these prices are worth paying. Choose shows by who listens to them; your own listening habits and the biggest download numbers are poor guides. Ask each show for its media kit, which should set out its audience, content, reach and rates; use the kits to narrow the list, then listen.

In Pew’s December 2022 survey, 28% of U.S. podcast listeners reported ever buying something promoted or discussed on a podcast. That is a listener-history measure, not an ad conversion rate or a guaranteed return.pewresearch.org (opens in a new tab)

Listen to several recent episodes of each finalist. You will learn quickly whether the host's tone suits your brand and whether you want to be associated with the guests. Libsyn recommends giving hosts talking points rather than a script, so the read sounds like the host. Watch the shows your competitors sponsor as well: when a sponsorship ends, the slot may come free.

For B2B companies: buy ads or run a show?

Buying ads on other shows is one way to reach buyers through podcasts. The other is to sponsor a show of your own, with a senior executive or the founder as host, and pay for its production instead of airtime.

The two do different jobs. An ad buys reach with an audience someone else built. A company show builds relationships with the people you interview. I've written that podcasting is networking: in 2017 I traced over 60% of the clients I had closed in the previous 12 months back to my podcast. In 2023 I described ABM podcasting as "free consulting and customer development interviews while creating amazing content at the same time". If your buyers are a known list of accounts, a show that interviews them can do more than a host read on a show they may not hear.

A company show has its own costs. Production is quoted by scope, and its audience grows slowly without promotion, which is where paid distribution comes in (the podcast promotion services guide compares the options). That is a different purchase from buying ads on other shows: you pay to bring listeners to your own episodes. Listen Network (opens in a new tab), which I own, sells this as guaranteed downloads. Its site says clients choose a minimum download count, typically 250 to 500 per episode, targeted through LinkedIn and Google Display down to job function, with downloads that its FAQ says follow version 2.2 of the IAB guidelines. No price appears on its homepage or FAQ.

Whichever route you take, decide first what the podcast budget must achieve: reach with a defined audience, relationships with named accounts, or both. Then price each option against that, using the CPM arithmetic above for ads and a scoped quote for a show.
