Publishing and professional handoff

How much money can you make writing a book?

August 16, 2026 · The StoryProp team

The Authors Guild's 2023 income survey — 5,699 published US authors, the largest of its kind run in America — found that the median author earned $2,000 from books in 2022, and $5,000 counting every kind of author-related income. Full-time authors publishing commercially with traditional publishers reported a median of $15,000 from books and $25,000 all in. In the same survey, the top tenth of established full-time authors reported a median of $275,000. All three are the answer, because a book does not pay a wage. It pays a distribution, and this article maps where that money sits and which levers move you up it.

Some housekeeping on that survey, because it holds up much of what follows. Codex Group fielded it for the Guild between February and April 2023, covering calendar-year 2022 income, and it remains the Guild's most recent income study. Respondents volunteered, recruited through 41 partner organisations, so it describes authors connected to the industry rather than a census. Every figure it reports is a median, deliberately: averages are meaningless here, because one respondent in the equivalent self-publishing survey reported $11 million in a single year.

Where the money actually sits

The most useful table in the whole study splits established full-time authors — first book published 2018 or earlier, non-zero income, n=1,459 — into income deciles. The median for that group was $12,000 in 2022, and the bottom half of it had a median of $1,300. The shape underneath those medians is the part that never makes a headline.

Two things follow. The top of that chart is not a lottery ticket: $275,000 is the median inside the top decile, so roughly one in ten established full-time authors here drew a professional salary from books alone. And the movement since 2018, inflation-adjusted within the same cohort, has been down at the top and up in the middle: the top decile fell 17% while the sixth through eighth rose 6% to 11%. Worth deleting from your head too: the viral claim that published books almost never sell more than a handful of copies. The journalist who published it has called it the most consequential reporting mistake of her career, and BookScan's own analyst could not reproduce it. Circana's Kristen McLean, across 45,571 frontlist titles from the ten largest US publishers, puts it at 15% selling fewer than 12 print copies and 66% fewer than 1,000 in a 52-week window of US print retail.

Trade publishing: the advance is the number

A publisher licenses the right to publish and pays an advance against royalties, in instalments on signing, on delivery and on publication. It is yours: a normal contract has no clawback if the book never earns it back. One public, standardised scale for advance size exists, the bands agents use when reporting deals to Publishers Marketplace — a nice deal up to $49,000, a very nice deal $50,000 to $99,000, a good deal $100,000 to $250,000, a significant deal $251,000 to $499,000, a major deal $500,000 and up, counting the total across every book in the contract. Reporting is voluntary, so visible deals skew large. Nobody publishes a median debut advance, and the most-quoted range for a first-timer, $5,000 to $15,000 a book, traces to one literary agent's blog post from March 2012. The rates that genuinely are published are the royalties.

The base is where the money hides. Print royalties are a share of the cover price; ebook and digital-audio royalties are a share of the publisher's net receipts, a smaller figure resting on retailer terms the publisher does not disclose — so a 25% ebook rate and a 10% hardcover rate are not comparable quantities. The print side works out exactly. Rebecca Yarros's Onyx Storm listed its standard hardcover at $29.99, so at the model contract's rates a copy pays $3.00 for the first 5,000 sold and $3.75 for the next 5,000: $33,750 for 10,000 copies, before an agent's commission. A $50,000 advance, the floor of the very nice deal band, is repaid at roughly 13,600 hardcover copies. Which is why the advance, not the royalty rate, is the term to negotiate hardest.

Self-publishing: Amazon publishes the whole formula

On Kindle Direct Publishing every input is a published rate, so you can calculate your income per sale before you write a word. An ebook listed between $2.99 and $12.99 on Amazon.com earns 70% of list price, less a delivery fee of $0.15 per megabyte in the US; anything outside that band earns 35% of list with no delivery deduction. The upper limit is new — the $9.99 ceiling stood from 2007 until 7 July 2026 — and Amazon does not migrate titles automatically: a book already priced above $9.99 stays on 35% until its author re-selects the option. On a $12.99 ebook that one checkbox is the difference between $4.55 and $8.88 a sale.

Print runs on a second published formula, and it changed on 10 June 2025. Amazon pays 60% of list minus printing cost when a paperback or hardcover lists at $9.99 or above on Amazon.com, and 50% minus printing cost at $9.98 or below. Printing a 300-page black-ink paperback costs $4.60 under KDP's published formula of $1.00 plus $0.012 a page — so the identical book pays $0.39 at $9.98 and $1.39 at $9.99, and one cent of list price multiplies the author's royalty by 3.6. KDP's own worked example follows the same arithmetic: a 333-page paperback at $15.00 earns (0.60 x $15.00) minus $5.00 in printing, or $4.00 a copy. Price is not a marketing afterthought here; it is the largest single term in your income.

Against that sit the costs. Reedsy, working from more than 230,000 freelancer quotes, puts editing, cover and formatting for a typical adult title at $2,940 to $5,660, with cover design at a median $930 across 9,600 collaborations in 2025; Written Word Media's survey of 1,346 indie authors shows most spend far less. Take the lower figure and a $4.99 ebook on the 70% option with a 2MB file, paying $3.28 a sale, and break-even is about 897 copies — or about 1,726 at the top of Reedsy's range. Through Kindle Unlimited instead, a 300-KENP-page book read cover to cover paid $1.38 at June 2026's rate of $0.004615 a page, putting break-even near 2,130 complete reads. Those are four-figure targets, not miracles.

That Kindle Unlimited pool is the hardest published number in self-publishing. Amazon announces the size of the KDP Select Global Fund every month; its twelve 2025 announcements sum to about $699.9 million paid out to authors, and May 2026 set a record at $66.9 million. Amazon never says how many titles share it, so per-author averages are invented — but as a measure of money reaching self-published authors, roughly $700 million a year is about 70% the size of the $1.0 billion trade ebook market the Association of American Publishers' panel recorded for 2025. KDP pays it out monthly, about 60 days after the month of sale, and direct deposit has no minimum balance in any marketplace.

Genre and catalogue: the two levers with the biggest numbers attached

That is the Alliance of Independent Authors' 2023 survey, 2,261 qualified responses, screened for authors spending at least half their working time on writing and publishing — so it reports what each genre pays people already doing this as a job. ALLi's 2025 wave puts the median across that population at about $13,500, growing 6% year on year, against a mean above $80,000 in the same sample of 1,520. Romance leads on the largest sample in the survey, and the print market agrees: Circana BookScan counted 51 million US print romance units over the twelve months to mid-2025, more than double the volume four years earlier, and named romance the leading growth category of the whole US print market in 2025. If you hold two book ideas and no strong preference between them, the market is telling you something, and romance that keeps its promise is a craft problem with an enormous readership attached.

No dataset here rewards one book the way it rewards a shelf of them. Written Word Media found roughly 80% of authors with one to three titles earning under $100 a month, while authors with 25 or more reported a median near $3,000 a month; its other strong correlate is an email list, about $300 a month for authors who have one against about $15 for those who do not. The Authors Guild found the same compounding on its own side of the fence: among established full-time authors, self-published median book income rose 110% in real terms between 2018 and 2022, to $19,000 against $10,000 for traditionally published authors — and those self-published authors carried about 40% more titles each. Career trajectory in this business is a catalogue, not a debut.

The case for writing it

The market you would be entering is large and it is not shrinking. The Association of American Publishers put US trade publisher revenue at $21.2 billion for 2024, up 4.4% year on year. Circana BookScan counted 762.4 million US print units sold in 2025, up 0.3% and a second consecutive year of growth. The Audio Publishers Association recorded $2.43 billion in US audiobook sales in 2025, up 9% and a fourteenth consecutive year of growth. The UK Publishers Association put the UK consumer market at £2.6 billion in 2025, up 3% — the trade slice of a record £7.4 billion total that is mostly academic and education revenue. Every one of those dollars and pounds was paid out over a book that somebody finished.

Books also do not expire, and that changes the arithmetic more than anything else here. Berrett-Koehler's long-running industry analysis puts backlist at roughly three-quarters of US retail book sales, and Circana's top-ten list for the first half of 2025 shows why: Atomic Habits, published in 2018, sold 439,849 print copies in those six months, and Dr. Seuss's Oh, the Places You'll Go!, published in 1990, sold about 436,000 — each outselling all but a handful of that season's new releases. Production costs are paid once; the royalty keeps arriving. It is also why the lane these surveys understate deserves naming: for a consultant, a founder or a coach, royalties can be almost incidental next to what the book does as a credential, and turning expertise into a book optimises for reaching the right hundred readers rather than the most.

The upside cases are documented, too, not folklore. Andy Weir self-published The Martian on Kindle at $0.99 in 2011, earning about $0.35 a copy across roughly 35,000 copies in its first months — some $12,000 in KDP royalties, after which Crown bought print rights and the film followed. Brandon Sanderson raised $41,754,153 from 185,341 backers on Kickstarter in 2022 to publish four novels himself, gross of printing and fulfilment. Amazon said in 2022 that more than 2,000 self-published authors had earned above $100,000 in KDP royalties, with thousands more above $50,000; it gives no denominator, so read that as a population rather than a probability — but its entry requirement is a finished book, then another one. The distance between the $618 row and the $95,385 row in that catalogue table is measured in finished drafts, and that is the one input entirely inside your control.

Every figure on this page rests on the same input: a finished book, and then the next one. StoryProp drafts with you a piece at a time in plain language, and the decisions you confirm — canon, characters, style rules — become records it reads before it writes again, so book two starts with book one's world intact instead of a folder of notes you have to reread.
