This shows the royalty pool ACX pays to the rights holder before any royalty-share split with a narrator. It does not include member credit sales, which ACX historically pays at a flat per-credit rate rather than a percentage of list price.

The 40% and 25% Plans, Compared

ACX offers two royalty structures, and the choice is a trade between rate and distribution rights, not a straightforward better-or-worse decision. Unlike Kindle's ebook royalty, there is no delivery fee subtracted from either plan — the percentage is applied directly to the list price.

Formula

Royalty = List Price × Royalty Rate
40% Exclusive Plan: Rate = 0.40 (requires seven-year exclusivity with ACX/Audible/Amazon/iTunes)
25% Non-Exclusive Plan: Rate = 0.25 (allows simultaneous distribution elsewhere)

At the same list price, the 40% plan always pays more per ACX sale — the trade-off is exclusivity, not a break-even threshold the way Kindle's file-size delivery fee creates one. The 25% plan only comes out ahead in total earnings if the additional retailers it unlocks generate enough extra sales volume to outweigh the lower per-sale rate on every platform, ACX included.

What Seven-Year Exclusivity Actually Means

Choosing the 40% plan commits the audiobook to ACX's distribution network — Audible, Amazon, and iTunes — for seven years from the agreement date, with no sales through other audiobook retailers or platforms during that term. That is a long commitment relative to how quickly a title's sales channels can shift, which is the real cost being weighed against the higher rate.

Audible dominates audiobook retail

Audible holds the largest share of the audiobook retail market by a wide margin, which is the main argument for the 40% exclusive plan — the higher rate applies to the channel most audiobook buyers already use.

Non-exclusive opens libraries and direct sales

The 25% plan allows distribution to library platforms, direct-to-listener storefronts, and other retailers ACX exclusivity would block — relevant for authors building an audience outside the Amazon ecosystem specifically.

The choice locks in at production, not per sale

Unlike Kindle's royalty plan, which can be changed per title at any time, ACX's exclusivity commitment is set when the audiobook is produced and cannot be switched mid-term without ending and rebuilding the distribution agreement.

Royalty Share Agreements With a Narrator

Many audiobooks are produced under a royalty share agreement, where a narrator provides production work in exchange for a percentage of the royalty pool instead of an upfront fee. The split is negotiated per project and set out in the ACX contract — this calculator shows the full royalty pool ACX pays the rights holder, before any such split between author and narrator is applied.

Knowledge Base

ACX Audiobook Royalties Methodology.

ACX pays audiobook royalties as a straight percentage of list price, with no delivery fee to subtract the way Kindle's ebook royalty has. The decision that actually matters is which of the two royalty plans to choose, since that choice trades a higher rate for a seven-year exclusivity commitment.

The Calculation Branch

Royalty = List Price × Royalty Rate | 40% Exclusive plan: rate = 0.40, requires 7-year ACX/Audible/Amazon/iTunes exclusivity | 25% Non-Exclusive plan: rate = 0.25, allows simultaneous distribution elsewhere

Industrial Standards.

This tool multiplies the entered list price by the selected plan's royalty rate to show the royalty ACX pays per retail sale, and shows what the other plan would have paid at the same price for direct comparison. It does not model ACX's separate flat-rate payout for Audible membership-credit redemptions, which is a fixed amount per credit rather than a percentage of list price, and varies by ACX's own published credit-value schedule rather than the title's list price.

In-Depth Analysis & Reference Data

The 40% plan's higher rate is the reward for the exclusivity ACX requires in exchange for it — there is no file-size-driven break-even calculation the way there is between Kindle's 70% and 35% ebook plans, because ACX charges no delivery fee on either plan. At an identical list price, 40% always beats 25% on ACX itself; the only reason to choose 25% is to sell through channels the exclusivity would otherwise block.

List price on ACX is typically set within bands tied to the audiobook's finished runtime rather than freely chosen the way an ebook price is, which is worth checking before assuming a specific price point is available for a given title.

Registry Questions & FAQ.

Can I switch from the 25% plan to the 40% plan later?

Not mid-agreement without ending the existing distribution deal and rebuilding it, since the 40% plan's exclusivity commitment is set at production time, not adjusted per sale the way Kindle's royalty plan can be changed.

Does a lower list price ever favor the 25% plan?

Not on rate alone — 40% of any list price is always more than 25% of the same price, since ACX applies no delivery fee to either plan. The 25% plan only wins in total earnings if it unlocks enough extra sales volume elsewhere to outweigh the lower ACX rate.
