Podcast Ad Revenue Calculator accuracy and testing

Formula source

• Net ad revenue = downloads per episode x episodes x ad slots x fill rate / 1,000 x CPM x (1 - sales commission) - production cost.

Test cases

Known limitations

• These calculators are planning tools. They do not fetch current platform pricing, read private dashboards, model taxes, guarantee sponsor demand, or replace legal, tax, accounting, or contract review.

Assumptions

• All fees, rates, commissions, CPMs, conversion rates, refund rates, and costs are user-entered assumptions.
• No current Gumroad, Lemon Squeezy, Patreon, podcast advertising, or brand deal pricing is hardcoded.
