Prerequisites
- A finished manuscript formatted for print
- Your book's final page count and ink type decided
Paperback royalties work nothing like eBook royalties, and the difference catches out almost every first-time self-publisher. eBooks have no unit cost. Paperbacks are printed one at a time, and Amazon takes that cost out of your money, not its own.
The Formula
Amazon states it plainly:
(Royalty rate × list price) − printing costs = royalty
Three inputs. The rate is decided by your price, the printing cost by your page count and ink.
The $9.99 Breakpoint
This is the single most consequential number in paperback publishing, because the rate jumps rather than sliding:
| List price on Amazon.com | Royalty rate |
|---|---|
| $9.98 and below | 50% |
| $9.99 and above | 60% |
One cent changes your rate by a fifth.
⚠️ Warning
Pricing a paperback at $9.99 is not a psychological trick borrowed from retail — it is the exact threshold where Amazon's royalty rate changes. Pricing at $9.95 or $9.98 to look cheaper costs you 10 percentage points of royalty on every copy sold, forever.
Work it through on a book with $4.50 printing costs:
| List price | Rate | Gross | Minus printing | You keep |
|---|---|---|---|---|
| $9.98 | 50% | $4.99 | −$4.50 | $0.49 |
| $9.99 | 60% | $5.99 | −$4.50 | $1.49 |
A one-cent price increase triples the royalty. That's not a rounding effect — it's the rate change compounding with a fixed printing cost.
Printing Costs Decide Viability
Amazon publishes printing costs by marketplace, page count and ink type rather than as one figure, so use its official calculator rather than any number you read in an article — including this one.
What matters is the shape of it, which Amazon does publish:
Fixed cost + (page count × per-page cost) = printing cost
That formula tells you most of what you need:
- Page count is the main driver. The per-page component scales linearly, so a 400-page book costs far more to print than a 150-page one.
- Colour ink is dramatically more expensive than black. A colour interior can make a book unsellable at any reasonable price.
- Ink and paper type change both components, so two books of identical length can print at very different costs.
ℹ️ Good to Know
This is why so many self-published non-fiction paperbacks are 150–250 pages. It isn't a content decision — beyond a certain page count, printing cost eats the royalty unless you raise the price past what readers will pay.
Minimum and Maximum Prices
Amazon enforces a minimum list price on every paperback, calculated so that royalties exceed printing costs. You cannot price a long book cheaply — the system won't let you sell at a loss.
At the other end, the maximum is $250 USD on Amazon.com, with equivalent caps elsewhere such as $350 CAD on Amazon.ca.
If KDP rejects your price as too low, that's the minimum rule, and the fix is either fewer pages, black ink instead of colour, or a higher price.
How This Compares to eBooks
The two formats reward opposite instincts.
eBooks pay up to 70% within a set price band, minus a small delivery cost that averages a few cents. Margins are high and page count barely matters.
Paperbacks pay 50–60% minus a real manufacturing cost that scales with length. Margins are thin, and length is expensive.
Which is why most self-publishers price the paperback higher than feels comfortable and treat it as a credibility object — something that makes the book real and reviewable — while the eBook does the earning.
✅ Action Step
Before you finalise your manuscript, run your actual page count through Amazon's printing cost calculator and compute the royalty at $9.99. If the result is under a dollar, you have a structural problem that no amount of marketing fixes — cut pages, switch to black ink, or plan to price higher.

Frequently Asked Questions
What royalty does Amazon KDP pay on paperbacks?
50% or 60%, depending on list price. On Amazon.com, list prices of $9.99 and above earn 60%, and prices at or below $9.98 earn 50%. Printing costs are then subtracted from that amount.
How is KDP paperback royalty calculated?
Amazon states the formula as (royalty rate x list price) - printing costs = royalty. So a $15 book at the 60% rate with $5.00 printing costs pays $9.00 minus $5.00, which is $4.00.
Why does one cent change my paperback royalty so much?
Because the rate jumps at $9.99 rather than sliding. Pricing at $9.98 earns 50% while $9.99 earns 60%, so the extra cent raises your rate by a fifth. Pricing just below the breakpoint is the most common self-publishing mistake.
What is the maximum price for a KDP paperback?
$250 USD on Amazon.com, with equivalent caps in other marketplaces such as $350 CAD on Amazon.ca. Amazon also enforces a minimum list price per book, calculated so that royalties exceed printing costs.
