Most authors have no idea how much Amazon and Audible take off the top. These calculators show you the real numbers — and what changes when you own the channel.
The dominant platform comes at a steep author cost. Here's what the fine print means for your income.
Audible sets what listeners pay based on runtime tiers — not your brand, not your story's value.
Members redeem a ~$8 credit on a $24 book. You're royaltied on the credit value — not the retail price.
ACX exclusive locks your audiobook to Amazon/Audible only for 12 months. No direct sales during that window.
No email, no purchase data, no follow-up. Every sale vanishes into Amazon's ecosystem.
Run the KDP calculator for your ebooks, the audiobook calculator for your narrated titles. The gap between what you're earning and what you could earn is bigger than most authors expect.
You set the price on KDP — Amazon does not. But the royalty tier you choose determines how much Amazon takes — and pricing outside the 70% range automatically drops you to 35%.
Drag the sliders. Compare what Audible pays against what you'd keep selling to the same readers from your own platform. The gap compounds across a series.
Standard novel — thriller, romance, fantasy debut.
The numbers above are theoretical until you have a platform to send readers to. We build the author websites and direct-sales systems that make it real.
