KDP Royalties Explained: The 70% vs 35% Rule and What You Actually Earn

Almost every pricing mistake an indie author makes traces back to one rule that Amazon states plainly and most writers price straight past: Kindle Direct Publishing pays a 70% royalty only when your ebook is listed between $2.99 and $9.99 in the US.^[1] Below $2.99 or above $9.99, the rate falls to 35%. That single boundary — not your genre, not your ambition, not what feels fair for the work — governs what you actually take home on every copy sold. Price on the math and the band works for you; price on instinct and it quietly halves your income.

This is a numbers piece, because pricing is a numbers problem. We will work the real figures: the two royalty options, the delivery fee that eats into the 70% rate, the notorious $9.99 cliff, why $0.99 rarely wins as a permanent price, how Kindle Unlimited page reads change the equation, and how the wide retailers pay differently from Amazon. Every figure here is dated, because Amazon changes its rates and rules silently and often — always verify the current band in your own KDP dashboard before publishing.

What is the 70% royalty band on Amazon KDP?

KDP gives you two royalty options when you publish an ebook. The 70% option is available only for list prices from $2.99 to $9.99 (in the US and most major stores), and it subtracts a per-megabyte delivery fee before paying out. The 35% option applies at any price below $2.99 or above $9.99, and charges no delivery fee. The 70% formula, per Amazon's own royalty documentation, is 0.70 × (list price − VAT − delivery cost).

The delivery fee is $0.15 per megabyte. For a typical text-only novel at roughly 0.4MB, the fee is about $0.06 — trivial. A 10MB image-heavy file, however, adds $1.50 in delivery cost per sale, which at a $2.99 price erases most of the margin advantage of the 70% rate over 35%. Keep files small, and the delivery fee stays a rounding error. Here is what the two options pay across the common price points:

Read that table twice. Everything about ebook pricing on Amazon flows from the shape of it: earnings climb smoothly across the 70% band, then fall off a cliff the moment you step outside it in either direction. One number that deserves special attention is $1.99: across four consecutive annual Smashwords sales surveys, $1.99 earned authors 73% less than the average of all other price points — it sells fewer copies than $0.99 and still triggers the 35% rate, losing on volume and margin simultaneously.^[2] If you must price at the low end, choose $0.99 for raw units or clear $2.99 for revenue. The ground between is where money goes to die.

How does the $9.99 cliff cut your earnings?

The top edge of the band is where authors lose the most money by trying to earn more. At $9.99 you take home about $6.89. Raise the price a single dollar to $10.99 and you drop to the 35% rate, earning about $3.85 — a loss of roughly $3.04 on every copy even though the buyer paid more. To net the same $6.89 at the 35% rate, you would have to charge about $19.69.

The lesson is counterintuitive but firm: on Amazon, $9.99 is the ceiling for maximizing per-sale royalty. If your book genuinely commands a premium price — a comprehensive business or professional title, a box set — the place to charge it is a wide retailer. Apple Books pays a flat 70% at every price point with no cap at all, so a $14.99 guide earns $10.49 there while it would earn only $5.25 on Amazon at 35%. Charging above $9.99 on Amazon is almost always a net loss per sale.

Why is a Kindle Countdown Deal different from a raw $0.99 price cut?

Here is the single most valuable exception in the royalty rulebook. KDP Select authors can run a Kindle Countdown Deal — a timed promotion that holds the 70% royalty even below $2.99. At $0.99 through a Countdown Deal you earn about $0.69 per sale; the same $0.99 price entered through the standard price field drops to the 35% rate and pays only $0.35. Same reader, same sticker price, and you keep roughly twice as much. On 500 promotional sales that is the difference between $345 and $175.

The mechanism has hard eligibility rules: your book must be enrolled in KDP Select for at least 30 days, your regular price must have been held at $2.99 or above for 30 days before the deal, the price must stay locked for 14 days after the deal ends, and the maximum duration is 7 days per 90-day Select term. BookBub's analysis of its own promotions found that deals lasting five days or fewer drove a 4× higher lift in post-promotion revenue than longer ones — so keep the window short and pointed, and step the price back up gradually after (e.g., $1.99 → $2.99 → full) rather than snapping it, to protect the rank you earned.

How do Kindle Unlimited page reads change the royalty math?

Sales are only half the royalty picture for many authors. Kindle Unlimited — Amazon's subscription reading service — pays authors not by the sale but by the page actually read, drawn from a monthly pool called the KDP Select Global Fund and divided across every page read that month. The per-page unit is called KENP (Kindle Edition Normalized Pages), and it floats rather than being fixed.

Per Written Word Media's monthly payout tracker, the KENP rate averaged about $0.00445 per page in 2025 — the highest since 2020 — and sat near $0.004888 in May 2026. A fully read 300-page novel earns roughly $1.35 in page reads at the 2025 average rate. The Global Fund reached $66.9 million in May 2026, up about 27-fold from its $2.5 million launch in July 2014; the per-page rate has stayed compressed, however, because total pages read across the program grew even faster. The discipline that survives all that drift: model your KU income at a conservative $0.004 per-page floor and never plan around the occasional $0.005 spike.

Which pushes fiction and nonfiction down different roads. In romance, fantasy, and thriller — where most top titles are enrolled in KU — the borrow button replaces the buy button for a large share of readers, and series authors optimize for read-through rather than list price. Nonfiction is the mirror image: KU readers rarely finish a reference book cover to cover, and a single $9.99 sale at 70% (~$6.89) often outearns the trickle of page reads the same content draws at $0.004 per page. If you write prescriptive nonfiction, price the book to be bought.

How do wide retailers pay differently from Amazon?

Amazon is not the only store, and the others do not share its tiered structure. Per Kindlepreneur's royalty breakdown and Draft2Digital's retailer guide, here is how the major platforms pay:

Two rules protect your royalty across all of them. First, your ebook must be priced at least 20% below your print edition, or Amazon will disqualify it from the 70% rate. Second, note that Amazon cut print royalties in June 2025, dropping paperbacks and hardcovers priced at $9.98 or below to a 50% print tier — ebook rates were unchanged. A 2024 Written Word Media survey found that multi-platform authors reported about 34% higher average monthly earnings than Amazon-exclusive authors, though going wide requires leaving KDP Select and its KU revenue behind. Price on this math, revisit it when the rates drift, and the royalty system stops being a mystery and starts being a lever you control.
