Free ACX / Audible audiobook royalty calculator. Enter distribution model, retail price, monthly sales, and narrator royalty-share percentage; outputs royalty per sale and monthly/annual earnings split between author and narrator.
Use when deciding between exclusive and non-exclusive ACX distribution, or when negotiating a royalty-share percentage with a narrator before signing a production agreement.
ACX's own royalty documentation explains the percentages, but this tool does the author/narrator split and monthly projection math for you in one place.
Royalty per sale = retail price × 40% (exclusive/Audible-only distribution) or × 25% (non-exclusive, multi-platform distribution).
That royalty is then split between author and narrator using the narrator royalty-share percentage you enter (default 50/50).
Monthly and annual totals multiply the per-sale author and narrator shares by your estimated monthly unit sales.
Exclusive distribution through ACX/Audible pays a 40% royalty share but locks you into Audible-only sales for the term of the agreement. Non-exclusive distribution pays only 25% but lets you also sell through other platforms like Apple Books and Spotify, which can add up to more total sales.
A royalty-share deal pays no upfront fee but splits ongoing royalties (often 50/50) with the narrator for the life of the audiobook. Paying per-finished-hour costs money upfront but lets you keep 100% of the royalty afterward — this calculator models the royalty-share arrangement.
Many authors can't afford a narrator's per-finished-hour rate (often $200–$400+/hour) upfront, especially for a first audiobook. A royalty-share deal shifts that risk onto the narrator in exchange for a long-term cut of sales, which is why 50/50 is a common default split.
Input
Exclusive distribution, $19.95 retail price, 10 sales/mo, 50% narrator share.
Output
Royalty $7.98/sale → $3.99 to you, $3.99 to narrator → ~$39.90/mo your share, ~$478.80/yr.
$19.95 × 0.40 = $7.98 total royalty per sale; split 50/50 with the narrator gives each party $3.99 per sale, times 10 monthly sales for the monthly totals.
