Independence
PublishCalc is an independently operated website. It is not affiliated with, endorsed by, sponsored by, or otherwise connected to Amazon KDP, Amazon.com, IngramSpark, or any other publishing platform, distributor, or print vendor. Any platform names referenced on this site are used solely to describe what our calculators help authors plan for.
Estimates only
All royalty figures, print cost figures, page count ranges, spine width figures, and profit projections shown on this site are produced by formulas built from publicly discussed publishing-industry planning assumptions. They are not pulled live from any publishing platform, and they do not represent official rates, fees, or guaranteed outcomes.
Publishing platforms set their own royalty rates, fees, and print costs, and these can change at any time without notice. Before pricing or publishing a book, verify the current, official figures directly with the platform or platforms you intend to publish through.
No financial or business advice
Nothing on PublishCalc constitutes financial, tax, legal, or business advice. The profit projection calculator in particular is a planning tool based on inputs you provide — it does not account for taxes, currency conversion, platform-specific promotions, returns, or many other real-world factors that affect actual earnings. Consult a qualified professional for advice specific to your situation.
No guarantee of results
Sales estimates, profit projections, and scenario cards are illustrative planning aids based on numbers you enter. They are not predictions, forecasts, or guarantees of what any book will actually earn.
Use at your own discretion
You are responsible for how you use the estimates produced by this site. PublishCalc and its operators are not liable for publishing, pricing, or business decisions made using information from this website.
