KDP Profit Calculation Guide
KDP royalty numbers look simple until you publish — then surprises appear in the printing cost, the 70% threshold, and expanded distribution. Here's the full profit math.
The KDP profit formula
Paperback/hardcover royalty = (list price × 0.60) − printing cost. Kindle royalty = list price × (0.35 or 0.70) − delivery fee on the 70% tier. Expanded distribution pays 40% (not 60%) of list, minus printing. There is no app fee, processing fee, or shipping cost — Amazon handles all of that. Your only real cost is printing for physical books.
Print cost is the silent margin killer
Black-and-white paperback: ~$1 fixed fee + $0.012 per page (US). A 300-page paperback costs ~$4.60 to print. Color (Premium) jumps to $0.07/page — the same 300 pages cost $22.00 to print, which often destroys royalty unless you price aggressively. Always run the math before committing to color interiors.
Kindle: 35% vs 70%
The 70% tier requires: list price between $2.99 and $9.99, enrolled in certain Kindle stores, and an additional per-MB delivery fee deducted from royalty. Outside that range you earn 35% with no delivery fee. For most books, $2.99–$9.99 on the 70% tier is dramatically more profitable.
Worked example — paperback
200-page B&W paperback, priced $12.99: royalty = ($12.99 × 0.60) − ($1.00 + $0.012 × 200) = $7.79 − $3.40 = $4.39 per copy on Amazon US. Expanded distribution on the same book: ($12.99 × 0.40) − $3.40 = $1.80 per copy.
Worked example — Kindle and hardcover
Kindle $4.99 on 70%: ~$4.99 × 0.70 − (small delivery fee ~$0.06 for a 2MB file) = ~$3.43 per sale. Hardcover 250-page B&W priced $24.99: ($24.99 × 0.60) − ($6.80 fixed + page cost) ≈ ~$8.50 per copy.
Pricing for real profit
Set list price so royalty per copy is at minimum $3–$5 on paperback and $2–$4 on Kindle — anything less and ad spend or returns wipe out the month. Use the KDP Royalty Calculator to test prices before publishing instead of guessing.
Frequently asked questions
- What royalty rate does KDP pay?
- 60% of list minus printing for paperback/hardcover on Amazon. 40% of list minus printing on expanded distribution. 35% or 70% on Kindle depending on price and delivery.
- Is 70% always better than 35% on Kindle?
- Almost always, when your price falls in the $2.99–$9.99 window. Outside that window you can only choose 35%.
- Why is my paperback royalty so low?
- Usually a high page count, color printing, or pricing too close to the print cost. Color paperbacks need a noticeably higher list price to leave room for royalty.
- Does KDP deduct ad spend from royalty?
- No — Amazon Ads bills you separately. Royalty pays out gross of ad spend, so you have to subtract ads yourself to see real profit.
