How the Tools Work

Every BookBird tool runs in your browser. Nothing you type is sent to us. Each calculator explains the rules it uses on its own page: Amazon KDP's published printing costs and royalty rates, paper thickness and trim sizes from KDP Help, and the formulas behind estimates such as sales from a Best Sellers Rank. Estimates are estimates; when Amazon's own figures differ, Amazon's figures win.

How the Guides Are Written

Guides explain the craft and business of self-publishing. Figures in them come from a named source, and pages that depend on Amazon's rules are updated when those rules change. If you find a mistake, write to us with the page and what is wrong, and we will correct it.

Advertising

BookBird is free to use and is open to advertising and partnerships. Advertising does not change what a tool calculates or how a guide answers a question.
