Audible replaced ACX's 40% / 25% royalty rates with 50% / 30% on 26 May 2026, and changed how membership sales are calculated at the same time. Most guides still quote the old arithmetic. This calculator runs both models, both distribution options, and royalty share against pay-for-production — then shows how many copies it takes to repay a narration quote.
50% is standard royalty share. 100% means you paid for production.
Most Audible volume is credit redemption, not cash purchase.
Default 7.48 is the Member Value at which a member sale pays what it did under the legacy model (14.95 × 0.50). ACX publishes neither figure per title — move them to see the sensitivity.

Royalty share means the narrator produces your audiobook for no upfront fee and splits royalties with you — usually 50/50 — for seven years. The rate went up in 2026, so the cash-sale side of that bet is worth more than the guides say. But the member-sale side is now volume-dependent revenue neither of you can model in advance, which makes the shape of the bet different rather than simply better.
The part that did not change is the term. ACX's documentation is explicit that royalty entitlement runs seven years and does not extend past it, and that during the term the recording cannot be distributed elsewhere. If you are signing this year, model cash sales as your floor and put the split, the enrollment rate, and any mid-term re-pricing in writing.

ACX Narrator Studio runs on your Mac: no uploads, no per-minute billing, chapter-wise MP3 masters to 44.1 kHz / 192 kbps, and distributor packs for the stores that accept synthesized narration — with each store's rule, source and check date shown in the app. It is not an Audible route, and the export gate says so.
