Royalty — KDP Royalty & Pricing Calculator

Royalty — KDP Royalty & Pricing Calculator — a premium, 100% offline digital tool by Aceplore. Runs entirely in your browser: no accounts, no subscriptions, your data never leaves your device.

A private, offline royalty and pricing calculator for self-published authors — the 70% and 35% bands, delivery cost by file size, print cost by page count, and exactly what you take home on every copy before you hit publish — 31 tools in one, with every rate editable and nothing leaving your device.

31 built-in tools in one app. A title list with a full per-title breakdown, production costs and other retail channels at their own rates; the eBook royalty worked both ways so you can see the 70% and 35% answers side by side, the price window that decides which one you get, the delivery fee computed from your file size and how big a bite it takes, print cost from page count, trim, ink and paper, and the paperback and hardcover royalty after that cost; a price finder that solves for the price that hits a target royalty, a price ladder that shows the royalty at every price so the band cliff is visible, a format comparison, and the real effect of a discount, a free run, tax-inclusive pricing and other currencies; a wide-versus-exclusive comparison and a rank estimate from figures you enter; a sales log, earnings by month, a forecast from your own run rate, break-even units against your production costs, per-title ROI, income goals and the units needed to reach them; plus a fully editable rate card, reports, CSV export and settings.

eBook Royalty, Price Bands & Delivery. The 70% and 35% figures computed together for the same price, the window that decides which one applies, and the delivery fee taken off the 70% option — shown as an amount and as a share of the royalty, because on a large file it is the whole story.

Price Finder & Price Ladder. Solve for the price that hits a target royalty per sale, then read the ladder — the royalty at every price, with the band recomputed each row, so the drop at the edge of the window is impossible to miss.

Print Cost, Break-even & ROI. Print cost from page count, trim, ink and paper, the paperback royalty after it, the units needed to cover your editing and cover costs, and the return per title once they are covered.

Royalty is a planning and organization tool for authors and publishers. Every figure it reports is computed to a published formula from the rates, measurements and figures YOU enter, and the rates are editable because retailers and printers change them without notice. Confirm the current rate card, page-count rules and file specification with your retailer or printer before you upload, and order a proof. Nothing here is a guarantee of acceptance, visibility, sales or income, and none of it is business, tax or legal advice. You are solely responsible for your own publishing decisions.
