When to use this

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.

How it compares

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.

Enter your values below. Calculations run locally as you type.

Audiobook sales

Royalty split

Royalty / sale
$9.97
50% of $19.95
Your share / sale
$4.99
50% of royalty
Narrator share / sale
$4.99
50% of royalty
Monthly (your share)
$49.88
10 sales/mo

At 10 sales/month you'd earn about $49.88/mo (~$598.50/yr), with the narrator earning $49.88/mo from the same sales. ACX pays a Royalty Share narrator for 7 years.

How it works

Royalty per sale = retail price × 50% (exclusive distribution) or × 30% (non-exclusive), ACX's new-model rates; legacy 40%/25% titles must switch by the end of 2026. Real payouts are lower because the rate applies to net receipts or, for membership listens, a share of Member Value, not the retail price.

For an exclusive title, that royalty is then split between author and narrator using the narrator royalty-share percentage you enter (default 50/50, ACX's fixed split; 0 if you paid per finished hour). Non-exclusive titles cannot use royalty share on ACX, so the narrator share is zero for them.

Monthly and annual totals multiply the per-sale author and narrator shares by your estimated monthly unit sales.

FAQs

Exclusive or non-exclusive distribution — which pays more?

Exclusive distribution through ACX/Audible pays a 50% royalty (new royalty model, 2026) but limits the audiobook to the outlets ACX distributes to (Audible, Amazon and Apple Books) for the term of the agreement, and it is the only option if your narrator is on royalty share. Non-exclusive distribution pays only 30% but lets you also sell through other platforms such as Spotify, libraries and your own site, which can add up to more total sales; the narrator must then be paid up front.

What's the difference between royalty share and pay-per-finished-hour?

A royalty-share deal pays no upfront fee but splits ongoing royalties 50/50 with the narrator for seven years, and on ACX it needs exclusive distribution. Paying per-finished-hour costs money upfront but lets you keep 100% of the royalty afterward. Enter 0% as the narrator share to model a per-finished-hour deal; the calculator does this automatically for non-exclusive titles.

Why split royalty with a narrator instead of paying them a flat fee?

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; on ACX the split is always 50/50 and the title has to be exclusive.

Worked example

Input

Exclusive distribution, $19.95 retail price, 10 sales/mo, 50% narrator share.

Output

Royalty $9.97/sale → $4.99 to you, $4.99 to narrator → ~$49.88/mo your share, ~$598.50/yr.

$19.95 × 0.50 (ACX's exclusive rate under the royalty model introduced in May 2026) = $9.97 total royalty per sale; split 50/50 with the narrator gives each party about $4.99 per sale, times 10 monthly sales for the monthly totals.

Common pitfalls

  • A per-finished-hour narrator fee is not deducted: enter 0% narrator share and weigh the up-front fee separately. Non-exclusive titles are always modelled this way, since ACX only allows royalty share on exclusive titles.
  • Real royalties can be affected by returns, promotional pricing, and bundle/membership credit redemptions, which pay out differently than a straight retail sale.
  • Non-exclusive distribution opens other retailers beyond Audible, but this calculator only models the ACX/Audible royalty rate, not combined multi-platform totals.

Exclusive at 50%, non-exclusive at 30%

The choice is between a 50% royalty for distributing exclusively through ACX (which places the audiobook on Audible, Amazon and Apple Books) and 30% for retaining the right to sell elsewhere. Those are the two rates of the royalty model Audible introduced on 26 May 2026, and the two this tool applies; the legacy 40% and 25% end with 2026.

The arithmetic is straightforward and the decision is not. Exclusivity pays two thirds more per sale on the dominant platform. Going wide means every other retailer, library distribution and direct sales — where margins can be far better — but it means giving up that uplift on the platform where most audiobook buying happens.

For most first-time authors without an existing audience elsewhere, exclusive earns more in practice. For an author with a direct-sales channel, it frequently does not.

Royalty share changes what you are comparing

Under a royalty-share deal the narrator takes a share of the royalty rather than a fee up front. On ACX that share is always half, which is the tool's default, and it lasts seven years. That turns a large fixed production cost into an ongoing revenue share for the life of the contract.

Royalty share is only open to exclusive titles: ACX requires a rights holder to choose exclusive distribution to offer a Royalty Share or Royalty Share Plus deal. A non-exclusive audiobook has to pay its narrator per finished hour, so when you pick non-exclusive the tool sets the narrator's share to zero and the whole royalty is yours. That makes the real comparison exclusive with royalty share against non-exclusive with an up-front fee, not the two rates side by side.

The comparison worth running is total cost over that term, not cost today. Paying a narrator per finished hour costs more immediately and keeps the whole royalty; royalty share costs nothing up front and, on a book that sells well, costs considerably more in total. On a book that sells poorly it is much the better deal. Which applies depends on a sales forecast, which is the part no calculator supplies.

  • ACX — How royalties work

    Audible's royalty model from 26 May 2026: 50% exclusive, 30% non-exclusive (the legacy 40%/25% ends at the close of 2026), and the seven-year term for royalty share producers. "To enter a Royalty Share deal, a rights holder must select exclusive distribution", so non-exclusive titles share nothing.
