A KDP royalty calculator is only as good as the pricing rules behind it, and on 7 July 2026 Amazon changed one of them: the 70% royalty band for Kindle eBooks on Amazon.com now runs $2.99 to $12.99, up from $2.99 to $9.99 (KDP Help, “eBook List Price Requirements”, data checked 2026-08-14). Of the six free calculators whose eBook rules could be read on 2026-08-14, five still show the old $9.99 ceiling — price a book at $12.99 in one of those and it tells you that you earn 35%, when Amazon now pays 70%.
Below is the official math first, per marketplace, then what each free calculator covers and where it is stale. None of it overlaps with FBA fees; for that, see the free FBA fee calculator comparison.
The Royalty Math Amazon Actually Publishes
Every number below was read off KDP Help on 2026-08-14. Two things trip people up: the rules are set per marketplace, not globally, and eBooks and print books use completely different formulas.
Kindle eBooks: 35% or 70%, and the Band That Changed in July 2026
Two formulas, from the KDP Digital Book Pricing Page (last updated 21 April 2026):
- 35% option:
35% Royalty Rate x (List Price – applicable VAT) = Royalty - 70% option:
70% Royalty Rate x (List Price – applicable VAT - Delivery Costs) = Royalty
The 35% option applies in any territory and deducts no delivery cost. The 70% option applies only inside Amazon’s Available Sales Territories, and in Brazil, Japan, Mexico and India it also requires KDP Select enrolment — without it you earn 35% there.
| Marketplace | 70% band | 35% floor (under 3 MB) |
|---|---|---|
| Amazon.com | $2.99 – $12.99 | $0.99 |
| Amazon.ca | C$2.99 – C$12.99 | C$0.99 |
| Amazon.co.uk | £1.77 – £12.99 | £0.77 |
| Euro marketplaces | €2.69 – €12.99 | €0.89 |
| Amazon.com.au | A$3.99 – A$15.99 | A$0.99 |
| Amazon.co.jp | ¥250 – ¥1,650 | ¥99 |
| Amazon.com.mx | MX$34.99 – MX$199.99 | MX$11.99 |
| Amazon.com.br | R$5.99 – R$31.99 | R$1.99 |
| Amazon.in | ₹99 – ₹599 | ₹49 |
That 35% floor rises with file size: on Amazon.com, $1.99 from 3 MB to under 10 MB and $2.99 at 10 MB or more.
Delivery costs are deducted under the 70% option only, per megabyte: US $0.15, Canada C$0.15, UK £0.10, eurozone €0.12, Australia A$0.15, Japan ¥1, Mexico MX$1, Brazil R$0.30, India ₹7. File sizes round up to the nearest kilobyte, and for sales in yen no delivery cost is deducted at all on files of 10 MB or more.
Paperback and Hardcover: 50% or 60%, Minus Printing
Print uses one formula for both formats: (Royalty rate x list price) – printing costs = royalty. The rate is 50% or 60%, decided by one list price threshold that differs by marketplace.
| Marketplace | 50% at or below | 60% at or above |
|---|---|---|
| Amazon.com | 9.98 USD | 9.99 USD |
| Amazon.de / .fr / .it / .es / .nl / .ie / .com.be | 9.98 EUR | 9.99 EUR |
| Amazon.co.uk | 7.98 GBP | 7.99 GBP |
| Amazon.ca | 13.98 CAD | 13.99 CAD |
| Amazon.com.au | 13.98 AUD | 13.99 AUD |
| Amazon.co.jp | 999 JPY | 1000 JPY |
| Amazon.pl | 39 PLN | 40 PLN |
| Amazon.se | 109 SEK | 110 SEK |
Amazon.pl and Amazon.se appear in the paperback table only. Expanded Distribution pays 40% of list price minus the same printing cost.
Printing cost is Fixed cost + (page count * per page cost). For black ink on cream or white paper at regular trim:
| Marketplace | 24–110 pages (fixed only) | 110–828 pages |
|---|---|---|
| Amazon.com | $2.30 | $1.00 + $0.012/page |
| Amazon.ca | C$2.99 | C$1.26 + C$0.016/page |
| Amazon.co.uk | £1.93 | £0.85 + £0.010/page |
| Euro marketplaces | €2.05 | €0.75 + €0.012/page |
| Amazon.com.au | A$4.74 (24–108 pages) | A$2.42 + A$0.022/page |
| Amazon.co.jp | ¥422 | ¥206 + ¥2/page |
On Amazon.com, large trim runs $1.00 + $0.017/page above the threshold, standard colour $1.00 + $0.0255/page and premium colour $1.00 + $0.065/page at regular trim. Amazon.com.br, Amazon.in and Amazon.com.mx support no print distribution.
Worked Examples You Can Re-Check by Hand
Redo these by hand — that is the test to run against any tool before trusting it with a price.
1. Kindle eBook, Amazon.com, 70% option, 2 MB file, $9.99. Delivery = 2 × $0.15 = $0.30, and US customers pay no VAT: 0.70 × ($9.99 − $0.30) = $6.78 per sale.
2. The same book at $12.99, eligible for 70% only since 7 July 2026: 0.70 × ($12.99 − $0.30) = $8.88. Under the old ceiling it forced 35%, paying 0.35 × $12.99 = $4.55 — a $4.33 swing per sale.
3. Paperback, Amazon.com, 300 pages, black ink, regular trim, $15.00. Printing = $1.00 + (300 × $0.012) = $4.60, the figure KDP uses in its own example. Above $9.99 the rate is 60%: (0.60 × $15.00) − $4.60 = $4.40.
4. The one-cent cliff. Same book at $9.98: (0.50 × $9.98) − $4.60 = $0.39. At $9.99: (0.60 × $9.99) − $4.60 = $1.39.
5. The same paperback on Amazon.co.uk at £9.99. The UK threshold is £7.99, so 60% applies. Printing = £0.85 + (300 × £0.010) = £3.85, giving (0.60 × £9.99) − £3.85 = £2.14.
KDP Printing Cost & Royalty Calculator (Official — the Benchmark)
kdp.amazon.com/royalty-calculator — visited 2026-08-14, loads without signing in.
This is the reference implementation, and it is deliberately narrow: paperback and hardcover only, no Kindle eBook mode. You pick marketplace, trim, interior type, paper and page count; it returns printing cost, minimum list price and royalty. Two limits are printed on the page itself — it “doesn’t include Expanded Distribution estimates”, and “figures generated by this tool are for estimation purposes only.”
Use it to settle any print disagreement between third-party tools. It cannot touch the 35%/70% eBook decision, which KDP surfaces inside title setup instead.
BookBeam KDP Royalty Calculator
bookbeam.io/kdp-royalty-calculator/ (print) and bookbeam.io/ebook-royalty-calculator/ (Kindle) — both visited 2026-08-14.
The print calculator is the most complete free one tested: eight stores, paperback and hardcover, three ink types, both trim classes, and it outputs VAT, printing cost, Expanded Distribution royalty, minimum list price and break-even ACoS alongside the royalty. Its stated print rule matches Amazon exactly: 50% at $9.98 or lower, 60% at $9.99 or higher.
Two accuracy notes. The copy on both pages still describes the 70% eBook band as “$2.99 to $9.99”. And its printing note says black-ink cost stays flat “until 108 pages”; on Amazon.com the flat band runs to 110 pages, 108 being the Amazon.com.au boundary. Both widgets are JavaScript-driven, so whether the eBook widget enforces the retired ceiling could not be verified from the page source.
Kindlepreneur KDP Royalty Calculator
kindlepreneur.com/kdp-royalty-calculator/ — visited 2026-08-14.
Covers eBook and print in several currencies, and is the most widely linked free calculator in self-publishing. It is also demonstrably running on the old band: the price ranges are hard-coded into the page, and the 70% entry reads range4: { from: 2.99, to: 9.99 } for USD and from: 1.77, to: 9.99 for GBP. The visible copy agrees — “Books priced between $2.99 and $9.99 can use the 70% royalty rate.”
The GBP floor of £1.77 is current, so the table was maintained at some point and only the ceiling is stale. Its print and delivery cost handling lines up with Amazon.
Manuscript Report Royalty Calculator
manuscriptreport.com/tools/royalty-calculator — visited 2026-08-14, no signup.
Handles Kindle, paperback and hardcover on one screen. Its print rules are current and precise: “60% for books priced $9.99 and above, 50% for $9.98 and below”. Delivery cost is correctly given as $0.15 per MB, and it is the only third-party tool tested that spells out the $2.99 minimum for eBook files over 10 MB.
The eBook ceiling is stale. Its guidance says the 35% option “makes sense only for books priced below $2.99 … or above $9.99”, advice that now inverts across the $10.00–$12.99 range.
HMD Publishing Royalty Calculator
hmdpublishing.com/education/tools/royalty-calculator — visited 2026-08-14.
The only tool tested that models non-Amazon channels, advertising coverage of Amazon, IngramSpark and Apple Books — the one to reach for if you distribute wide. Its print rule is not only correct but dated: “Since June 2025, the print royalty rate is tiered: 60% for books priced at $9.99 or above, and 50% for books priced below that threshold.”
Its eBook section repeats “$2.99-$9.99” through the page body and its structured FAQ markup, so the retired ceiling is baked into what search engines index from it too.
KDPEasy KDP Royalty Calculator
kdpeasy.com/tools/kdp-royalty-calculator — visited 2026-08-14.
The simplest tool tested: one price field, one page-count field, an immediate breakdown. Its default example is internally consistent with Amazon’s formula — it shows $9.99 × 60% − $3.25 printing = $2.74, and 0.60 × $9.99 − $3.25 does equal $2.744.
The problem is a hard validation rule beside the price field: “Price must be $2.99 - $9.99”. That enforces the retired ceiling rather than merely describing it, so the tool steers you away from a price now eligible for 70%.
Built Written KDP Royalty Calculator
builtwritten.com/tools/kdp-royalty-calculator — visited 2026-08-14, no signup.
The only calculator tested that carries the current eBook ceiling, and its page description states the position plainly: “a 50% tier for paperbacks under $9.99 and a $12.99 ebook ceiling.”
Its worked example re-checks cleanly against Amazon’s tables. It gives a 200-page black-and-white paperback at $12.99 a printing cost of “about $3.40” — Amazon’s formula returns $1.00 + (200 × $0.012) = $3.40 exactly — and a royalty of ($12.99 × 0.60) − $3.40 = $4.39, matching to the cent.

How to Sanity-Check Any KDP Royalty Calculator
Five inputs, about a minute. Run them before you let a tool set a price.
- $12.99 Kindle eBook, Amazon.com. If the tool refuses the price or reports 35%, it predates 7 July 2026. Correct behaviour is a 70% result.
- 300-page black-ink paperback at $15.00, Amazon.com. Printing cost must be $4.60 and the royalty $4.40.
- That paperback from $9.98 to $9.99. The royalty must jump from $0.39 to $1.39; a smooth curve there means one flat rate is being applied.
- The same book on Amazon.co.uk. The threshold must move to £7.99, not stay at the dollar figure.
- eBook file size from 1 MB to 8 MB. The 70% royalty must fall by 7 × $0.15 = $1.05. If nothing moves, delivery cost is not modelled.
Common Mistakes With KDP Royalty Calculators
- Treating the eBook band as global. The 70% ceiling is $12.99 on Amazon.com but ¥1,650 in Japan, ₹599 in India and A$15.99 in Australia. A US-only calculator quotes 70% on prices that pay 35% in half your markets.
- Forgetting KDP Select in four stores. In Brazil, Japan, Mexico and India the 70% option requires KDP Select enrolment. No free calculator tested asks about enrolment first.
- Ignoring VAT on eBooks. Amazon deducts applicable VAT before applying the rate, as
VAT rate / (1 + VAT rate) × list price. On a €2.99 book at 7% German VAT that is €0.20 off the top, before delivery costs. - Trusting one sentence about trim size. The Paperback Royalty page says trim size, bleed and cover finish do not affect printing cost, while the Paperback Printing Cost page prints separate Regular and Large Trim columns ($0.012 against $0.017 per page on Amazon.com). The tables are the operative rule.
- Comparing print and eBook royalties at face value. Print is net of printing cost, eBooks net of delivery cost only — the same trap as reading an Amazon referral fee without fulfilment cost beside it.
Frequently Asked Questions
What is the best free KDP royalty calculator?
For print, KDP’s own Printing Cost & Royalty Calculator, the source every other tool copies. For Kindle eBooks, Built Written was the only free tool tested on 2026-08-14 applying the current $12.99 ceiling.
Why does my calculator say 35% when KDP says 70%?
Almost always the retired $9.99 ceiling. Amazon raised the 70% maximum list price on Amazon.com to $12.99 on 7 July 2026, and most free calculators still enforce the old range.
Is there a KDP royalty calculator that works without an account?
Yes. KDP’s own calculator page loads without signing in, and all six third-party tools reviewed above ran without registration on 2026-08-14.
How do I calculate KDP royalties by hand?
For eBooks: 0.70 × (list price − VAT − delivery cost), or 0.35 × (list price − VAT). For print: (0.50 or 0.60 × list price) − printing cost, where printing cost = fixed cost + (page count × per-page cost).
Do KDP royalty calculators include Expanded Distribution?
Amazon’s own calculator states it does not; BookBeam shows an Expanded Distribution figure beside the Amazon royalty. The rate is 40% of list price minus the same printing cost.
Conclusion
A KDP royalty calculator is a lookup table with a form on top, and lookup tables go stale. The July 2026 band change caught five of the six free tools here; the per-marketplace thresholds — £7.99 in the UK, ¥1,650 in Japan, A$15.99 in Australia — catch most of them permanently. Use KDP’s own calculator for print, run the $12.99 test on any eBook tool, and keep the two formulas within reach. None of this carries over to physical products: see the Amazon FBA revenue calculator guide, and the Amazon author page guide for the identity layer above your KDP titles.
