Most first-time authors pick a Kindle price the way they pick a restaurant tip: a quick guess, rounded to something that feels right. Then they discover that the number they chose quietly decided their royalty rate, whether Amazon charges them a delivery fee, and which countries can buy the book at all. Price on KDP is not a marketing knob you turn later. It is a structural choice, and it is worth twenty minutes of your attention before you publish.
Before we start: KDP's terms change. Every number below reflects the program as it has operated through 2026, but treat this as a map, not a contract — confirm the current rates on your own KDP dashboard before you commit. Where a rule has exceptions by territory, we say so rather than pretending it is universal.
The Two Royalty Options, Honestly Described
KDP offers exactly two royalty plans per ebook, and you choose one when you set your price.
| 35% option | 70% option | |
|---|---|---|
| List price range (USD) | $0.99 – $200.00 | $2.99 – $9.99 |
| Delivery fee | None | Charged by file size |
| Territories | Effectively all KDP markets | Only the 70%-eligible list |
| Best for | Very cheap books, very expensive books, wide territory reach | Almost everything priced $2.99–$9.99 |
That table hides the trap most authors fall into. If you price at $2.99, you can take 70% and earn roughly $2.05 per sale after a typical delivery fee. If you price at $2.49 — fifty cents cheaper, which feels friendlier — you fall out of the 70% band entirely and take 35%, or about $0.87. You cut your price by 17% and your income by 58%. Pricing below $2.99 is a decision to earn a third as much per copy, so make it deliberately, not by accident.
The delivery fee nobody budgets for
Choose 70% and Amazon deducts a delivery fee based on the file size of your ebook, charged per copy sold. In the US store this has long been around $0.15 per megabyte. For a text-only novel of 1–2 MB, that is a rounding error. For an illustrated cookbook, a photo book, or a technical manual stuffed with full-colour diagrams at 20 MB, it is $3.00 taken off every single sale — which can exceed the entire 35% royalty you would have earned on the same book.
So the practical rule is: if your book is image-heavy, calculate both options before choosing. Compress your images properly, and check the delivered file size KDP reports for your uploaded file rather than the size of your source document. If you are unsure what a given price and file size actually nets you, our KDP royalty calculator does the arithmetic for both plans side by side.
What Price Should You Actually Pick?
There is no universal right answer, but there are defensible defaults by book type. These are starting points to test, not laws.
| Book type | Common launch price | Reasoning |
|---|---|---|
| Debut fiction, unknown author | $2.99 – $4.99 | Lowest price that still qualifies for 70%; reduces the risk a reader takes on an unfamiliar name |
| Series book 1 | $0.99 or free | Deliberately sacrificing royalty to sell books 2–5 at full price. Only makes sense if the later books exist |
| Non-fiction, general interest | $4.99 – $7.99 | Readers judge practical books partly by price; too cheap reads as thin |
| Professional / niche non-fiction | $9.99 | Top of the 70% band. Narrow audiences are far less price-sensitive than broad ones |
| Reference over 300 pages | Above $9.99 at 35% | Rare, but a genuinely comprehensive reference can earn more at $14.99/35% than $9.99/70% |
Notice the last row: $14.99 at 35% pays about $5.25, while $9.99 at 70% pays about $6.85 before delivery. The 35% plan only wins above roughly $19.99 on pure per-copy maths — so if you are considering it, you are making a bet about a specialist audience, not doing a calculation.
Why the $0.99 launch is usually a mistake
A $0.99 launch is the most commonly recommended and most commonly regretted tactic in self-publishing. It works in exactly one situation: you have a finished series and book one is a deliberate loss leader. It fails in the far more common situation — a single standalone title — because it earns about $0.35 a copy, it signals low quality to browsing readers, and, worst of all, it teaches Amazon's systems to show your book to bargain hunters who will never pay full price for your next one. You can always run a temporary countdown promotion later. You cannot easily undo an audience that only wants free books.
Kindle Unlimited: A Different Revenue Model Entirely
Enrolling in KDP Select puts your ebook in Kindle Unlimited and changes how you earn. Instead of a royalty per sale, you are paid from a monthly global fund according to how many pages readers actually read (KENP). The per-page rate is not fixed; it floats each month with the size of the fund and total pages read across the programme, and has historically hovered in the neighbourhood of half a cent per page.
The cost is exclusivity. For each 90-day term, that ebook cannot be sold anywhere else — not Apple Books, not Kobo, not your own site. The trade is worth making when:
- Your genre is heavily read in KU — romance, thriller, cozy mystery, LitRPG, and much of commercial fiction.
- Your book is long, and readers finish it. You are paid by pages read, so a completed 400-page novel earns roughly four times what a completed 100-page one does.
- You have no meaningful audience on other platforms yet, so exclusivity costs you little in practice.
It is usually the wrong trade for short non-fiction that readers dip into rather than read through, for books with an existing non-Amazon readership, and for anything you also sell directly to a mailing list.
Pricing the Paperback
Print royalties work on a different formula: roughly 60% of list price minus the printing cost, with printing driven mainly by page count, trim size, and whether the interior is colour. A 250-page black-and-white 6×9 paperback costs a few dollars to print, which sets a hard floor — KDP will not let you list below the point where royalty turns negative.
Two things matter here. First, Amazon requires the ebook to be priced at or below the print edition, so an unrealistically cheap paperback constrains your ebook. Second, a paperback priced near a familiar bookstore number ($12.99–$16.99 for most trade formats) makes the ebook look like the sensible-value option, which is exactly the contrast you want. If you are choosing a trim size, our print-on-demand guide covers how that decision flows through to cost.
How to Test a Price Without Guessing
Price is one of the few book variables you can change in minutes and measure honestly. A workable routine:
- Launch at your considered default from the table above and leave it alone for four to six weeks. Anything shorter is noise.
- Record units, not just royalties. A price rise that halves units but doubles income is a win on this book and a loss on your series, because fewer readers reach book two.
- Change one thing at a time. Changing price and cover in the same week teaches you nothing about either.
- Check your competition honestly — the ten books that actually rank for your main keyword, not the three bestsellers you admire.
- Revisit after each new release. Backlist pricing should serve the newest book, not the other way round.
Decide categories and keywords with the same deliberateness — they determine which price comparison a shopper is making in their head. Our guide to choosing KDP categories and keywords covers that side.
The Short Version
- $2.99–$9.99 is the 70% band. Falling below it costs you roughly two thirds of your per-copy income.
- Delivery fees punish large files. Compress images, and check both royalty plans if your book is heavy.
- $0.99 only makes sense for book one of a finished series.
- Kindle Unlimited pays by pages read and costs you exclusivity. Good for long commercial fiction, poor for short reference works.
- Keep the ebook at or below the paperback price, and use the print edition to make the ebook look like good value.
Pricing rewards the author who decided on purpose. Run your own numbers, write down why you chose what you chose, and revisit it when you have data instead of a hunch.
