What Is a Book Royalty?

How do KDP's 35% and 70% tiers work?

Price inside the $2.99–$9.99 band, meet Amazon's conditions, and your ebook earns 70% of list price minus a small delivery fee based on file size. Price below $2.99 or above $9.99 — or miss a condition — and the same book earns 35% with no delivery fee. The boundary at $2.99 is the most consequential number in independent publishing: $2.99 earns roughly $2.05 while $2.98 earns about $1.04.

The 70% conditions beyond price are straightforward but real: the book must be available for sale in all authorized marketplaces, meet content and formatting requirements, and in some regions the delivery fee reflects local costs. Most mainstream ebooks qualify without thought; problems arise with giant files (photo-heavy books where delivery fees bite) and territorial restrictions.

Delivery fees deserve their own line in your math because they scale with megabytes — roughly fifteen cents per megabyte in the US. A lean text novel pays pennies; a 200MB illustrated guide surrenders real money per sale. Compress images before uploading: every megabyte you trim is margin earned on every future sale forever.

How should price and royalty interact?

Think in earnings per reader, not percentage points. A $4.99 book at 70% keeps about $3.40; a $0.99 book at 35% keeps about $0.35. The cheaper book must sell roughly ten times the copies to match — possible with series read-through or promo velocity, ruinous as a standing price for a standalone. Percentage flatters; dollars decide.

The $2.99 floor shapes strategy across catalogs. Series starters often sit at $0.99–$2.99 to maximize sampling (accepting 35%) while later volumes hold $3.99–$5.99 at 70% to harvest read-through. The blended royalty per reader beats any single price's math — funnel pricing, not book pricing.

Promotions temporarily rewrite the equation. Countdown Deals preserve 70% at discount prices; ordinary price cuts don't. Free runs earn zero by design, buying rank and also-boughts instead. Judge every promo by total funnel earnings, never by the discounted book's royalty alone.

How do print and page-read royalties differ?

Print royalties subtract physical reality first. From the list price comes the printing cost (pages, ink, size), then Amazon's share of the remainder, and you keep what's left — typically 40–60% of list depending on specs. A $14.99 paperback might yield $4–6; the same content's ebook at $4.99 yields ~$3.40 with no printing involved. Formats are different businesses sharing a detail page.

KENP page-reads pay neither per sale nor per price — they pay per standardized page read from the monthly Select fund. A 300-page novel read fully often earns in the same neighborhood as one $4.99 sale, but the distribution differs wildly: many small payments from many samplers instead of fewer full payments from buyers. Cash flow feels different even when totals match.

Wide-store royalties roughly mirror KDP's bands with local variations — Apple, Kobo, and Google each take around 30% on agency-priced ebooks with their own conditions. Going wide doesn't change the arithmetic much; it changes the audience and the exclusivity cost. Compare channels on readers reached, not points of percentage.

An example: one reader's value across a trilogy

A thriller trilogy prices book one at $0.99 (35%, ~$0.35), books two and three at $4.99 (70%, ~$3.40 each). A reader who buys all three is worth about $7.15 in royalties — twenty times book one's royalty alone. The series earns through continuation, which is why standalone authors and series authors live in different economic universes.

The KU version of the same reader borrows book one (KDP Select enrolled), finishes all three via page-reads, then buys the box set wide for re-reading. Total value: three books' KENP plus a box-set sale royalty — often exceeding the buy-only path, because subscription reading removes every purchase decision except the first borrow.

Both funnels share one requirement: books two and three must exist. The entire royalty architecture of modern independent publishing rewards continuation — write the next book before optimizing the current price.

What royalty mistakes leave money behind?

Pricing at $2.98 or below from habit is the purest loss: a few cents of list price surrender half the royalty rate with no compensating volume. Audit every price against the $2.99 boundary deliberately — below it should always be a promo decision with an end date, never a standing accident.

Ignoring delivery fees on heavy files runs second. Authors upload print-resolution images to ebooks, pay megabytes of delivery on every sale for years, and never compress once. Run your files through the royalty calculator during setup and treat every megabyte as a permanent tax you chose.

Third is optimizing book-one price while books two-plus don't exist. No price rescues a funnel with no continuation; every pricing debate before the series is complete is premature. Finish the catalog, then price the system as a whole — the reader's total value, not any single book's percentage.

• Model niches with the Profitable Ebook Niches guide before locking prices.
• Never park a standing price just under $2.99 — the cliff halves royalties.
• Compress ebook images; delivery fees tax every sale forever.
• Price funnels (reader lifetime value), not single books.
• Use Countdown Deals, not ordinary cuts, for discounted 70%.
• Finish the series before fine-tuning any single price.
