Podcast Sponsorship Calculator

The Podcast Sponsorship Calculator estimates advertising revenue per episode, per month, and per year from downloads per episode, episodes per month, CPM, and ad spots per episode.

Formula

$\text{Revenue per episode}=\frac{\text{Downloads per episode}}{1{,}000}\times\text{CPM}\times\text{Ad spots}$ $\text{Monthly revenue}=\text{Revenue per episode}\times\text{Episodes per month}$ $\text{Annual revenue}=\text{Monthly revenue}\times12$

Worked example

For 20,000 downloads per episode, two ad spots, a $25 CPM, and four episodes per month:

1. Episode revenue: 20,000 / 1,000 x $25 x 2 = $1,000.
2. Monthly revenue: $1,000 x 4 = $4,000.
3. Annualized revenue: $4,000 x 12 = $48,000.

Questions

Is CPM paid for every download?

The formula assumes the entered downloads are monetized impressions. Actual campaigns may use downloaded, started, completed, or dynamically inserted impressions with different fill rates.

Does this include agency fees or commissions?

No. It estimates gross sponsorship revenue before commissions, production, sales, or platform fees.

Can episodes or downloads be zero?

Yes. The calculation module accepts non-negative values and returns zero revenue when the relevant input is zero.

Limitations

This is a gross planning estimate. Confirm the sponsor's CPM basis, fill rate, audience measurement, ad placement, and payment terms before budgeting.
