Amazon KDP Royalty Calculator
Work out your Amazon KDP printing cost and royalty per copy, the minimum price that breaks even, and what the ebook earns. Free, no sign-up.
Amazon pays 60% of a paperback's list price and then deducts what it cost to print the copy. That second half is the one that surprises people: printing is charged per copy, so a long book priced like a short one can earn a few cents, or nothing at all.
Page count is the lever. Below 110 pages a paperback costs a flat fee to print; above it, Amazon charges a fixed fee plus a per-page rate, so every extra chapter takes a little more out of every sale. The break-even price below is the lowest you can list at without losing money on each copy.
Common questions
- Is KDP royalty 35% or 70%?
- Both, for ebooks: 70% applies only between $2.99 and $9.99 and has a per-megabyte delivery fee deducted; outside that band Amazon pays 35% with no delivery fee. Paperbacks are a separate rate — 60% of list, minus printing.
- How much should I price my paperback at?
- Above the break-even shown here, then as close to comparable books in your genre as that allows. A long book forces a higher floor, which is one reason page count is a pricing decision and not only a creative one.
- Why does my long book earn so little?
- Printing cost is deducted per copy and scales with page count above 110 pages. At 600 pages the printing alone is several dollars, so a $12.99 list price leaves very little. Raise the price, or set the book at a smaller trim so it runs to fewer pages.
- Does this include Amazon's other fees?
- It is the printing cost and the royalty rate, which is what determines your earnings per copy. It does not model returns, advertising or the cost of a cover — those sit outside the royalty formula.
