Should you write a book for your business?

Yes — and the number to hold in your head is $11,350. That is the median gross profit reported by authors whose books had been out at least six months in A Comprehensive Study of Business Book ROI, the survey of 301 published nonfiction authors run by Josh Bernoff with Dr. AJ Marsden and published on 14 October 2024. Two-thirds of that group, 66%, finished in profit, at a median of $2.56 in gross profit for every dollar spent. Median revenue attributable to the book was $25,000, against a median total production and launch spend of $7,000.

Medians hide a lot here, so look at the spread. In the same cohort, 34% made no gross profit at all and one author was down $180,000. At the other end, 10% cleared between $250,001 and $1,000,000 and a further 7% cleared more than a million. It is worth knowing where the sample comes from: respondents were recruited through four author-service firms that sponsored the study, so they skew toward authors who invested real money in the project, and 86% were North American. Read it as the best available picture of people who took the book seriously — which is the group you would be joining.

Almost none of the money is in the book

The most useful finding in the study is where the return actually shows up. Across all authors reporting revenue, 47% of it came from something other than the book itself — speaking, consulting, workshops, courses. Among authors who generated $10,000 or more, that share rises to 63%; above $25,000 it reaches 69%. Bernoff's own summary of the data is the line to remember: the more money a business book makes, the less of it arrives as book money. Royalties are not the product. The book is the instrument that sells the thing you already sell.

Read that chart with its qualifier attached. Except for the advance, each median counts only the authors who reported income in that stream — $50,000 in consulting is the middle of 80 authors who won consulting work, not what a typical author earns. The advance is the exception: $5,500 is the median across 109 traditionally published authors including the 31% who received nothing.

The counterweight sits one page earlier in the report. Asked which revenue categories the book increased, 34% of authors reported higher speaking fees, 31% more consulting, 26% more workshop work and 18% a lift in their organisation's sales — while 31% reported no financial increase in any category at all. Which means roughly two authors in three saw an increase somewhere. Leads are the wider signal: more than 70% reported more leads or gigs after publication, and among those who did, the typical magnitudes were ten speaking gigs, seven workshop gigs, dozens of consulting leads or scores of coaching sessions.

What it costs, in money and in months

Median total spend to produce and launch was $7,000, and the path decides most of it: $2,550 self-published, $10,000 traditional, $23,000 hybrid. The line items are knowable. Authors paid a median $2,000 for a copy editor, $5,000 for a developmental editor, $6,000 for a book coach, and $25,000 for a ghostwriter on a median nine-month engagement — though only 8% used a ghostwriter at all. The Editorial Freelancers Association's 2026 rate chart, built from more than 1,100 people reporting what they charged during 2025, puts business and marketing ghostwriting at 50 cents to $1.00 a word, roughly double general nonfiction, so a 50,000-word book runs about $25,000 to $50,000 if someone else writes it. Nearly half of authors, 49%, met costs they had not expected.

Then there is the input nobody costs. The median author spent 10 months actually writing — 12 for traditionally published books, 6 for self-published ones, with 36% finishing in half a year or less. None of that time appears in any profit figure above, which means every return in this article is calculated as though your evenings were free. Ten months of your best thinking hours is the real price of a business book, and it is the only line on the invoice you can genuinely compress.

That table is not a ranking of publishing paths. Traditional publishers gatekeep, so the authors who get through arrive with larger platforms already built, and their advances count as revenue in the same column. The row worth noticing is the hybrid one, because the study was co-sponsored by a hybrid publisher and reported it anyway: hybrid authors spent the most, a median $23,000, and cleared the least, with 53% turning any profit. If you are choosing on economics alone, the self-published row is where a first book has the least to lose.

The line items that reliably disappoint

Two purchases stand out in the satisfaction data. Paid placement in bookstores cost a median $11,000 and satisfied 31% of the authors who bought it, the lowest score of the seventeen services measured — though only 12 authors bought it, below the study's own reliability threshold. PR agencies and launch specialists ran a median $15,000 at 53% satisfied. Compare the copy editor: $2,000, and 86% satisfied. The pattern across the whole table is consistent — the services closest to the manuscript pleased the most people, and the services closest to the marketplace pleased the fewest.

Bestseller placement is the extreme case. Forbes reported in February 2013 what business author Soren Kaplan's campaign cost: about 3,000 copies at $23.50 each, roughly $70,500 in books, plus a ResultSource fee typically above $20,000, to reach the Wall Street Journal list — and about three times the volume, some $211,500 in books, for the New York Times. Those are 2013 figures and that vendor shut down in 2014, so read them as order of magnitude. One current fact settles the question anyway: Publishers Weekly reported that the Wall Street Journal discontinued all six of its bestseller lists in November 2023, the hardcover business list included, when its Circana contract lapsed. That credential cannot be bought now because it no longer exists.

The other budgeting lesson is about paying up front. Scribe Media sold business-book packages from $24,000 to upwards of $135,000; on 12 April 2023 it could not make payroll, and on 24 May it laid off its staff by email, leaving authors who had paid for work that was never delivered, as the Association of Ghostwriters reported at the time. Stage your payments. And keep the first book's budget modest, because the study measured the link between money in and money out at R = 0.243 — statistically real, but explaining only about 6% of the variance in revenue. Revenue averaged $1.24 for every dollar spent, and that is a mean of revenue rather than the median $2.56 of profit per dollar at the top of this article: a different quantity, not a contradiction. Spending is not the lever. The manuscript is.

Copies are the wrong scoreboard

Authors expect more copies than they sell, consistently. The study's medians are 4,600 copies traditionally published, 1,600 hybrid and 700 self-published, against expectations of 8,900, 4,400 and 1,100 — self-reported by a self-selected sample, so treat them as shape rather than measurement. The important part is what the researchers found next: copies sold did not predict ROI, or whether an author met their goals. A book that reaches exactly the right 700 people beats one that sells 5,000 to strangers, and the revenue chart above is why.

One number in circulation deserves correcting, because it talks people out of starting. The claim that half of all published books sell fewer than a dozen copies is false. It began as an unsourced rhetorical question from a Department of Justice lawyer during the 2022 Penguin Random House–Simon & Schuster antitrust trial, was not accepted by the expert witness on the stand, and went viral through a 2024 blog post. Lincoln Michel's correction in Slate in April 2024 is the citable debunk: Circana BookScan data shows roughly 15% of frontlist titles from the top ten publishers sold fewer than twelve copies in a calendar year — and even that conflates one year with lifetime sales and counts every format's ISBN separately.

What the book buys that the spreadsheet misses

Ask business-book authors what changed and money is not the first answer. 68% reported significantly greater credibility with prospects and clients, 61% said their personal brand was worth more, 59% received more podcast invitations, 33% more approaches from news media and 32% higher-profile speaking engagements. Only 8% reported no improvement in anything. And 89% agreed that writing the book was a good decision, with 72% of all respondents agreeing strongly. Survivorship plays a part — people who regret a book are less likely to answer a survey about book ROI — but a split that lopsided across 301 authors is not noise.

There is independent evidence for the mechanism underneath those numbers. The 2025 Edelman-LinkedIn B2B Thought Leadership Impact Report, published in July 2025 from a survey of nearly 2,000 professionals, found 86% of decision-makers more likely to invite an organisation that consistently produces high-quality thought leadership into an RFP, 73% treating it as a more trustworthy guide to capability than marketing materials, and 60% willing to pay a premium for it. That report measures thought leadership broadly rather than books, but a book is the densest and longest-lived form the category has: one argument, made at length, in something people keep on a shelf and hand to a colleague.

So should you write one?

Yes, if you own an argument and not only competence. Most fields are full of capable people who know roughly the same things; what is rare is being the person who arranged the field's scattered common sense into a position and signed it. The signals that predict a book that works are unglamorous — you keep giving the same long explanation and it keeps landing, your method has a name and clients use it back to you, you disagree with the standard advice at specific points and can say exactly where. The test that matters most is whether the book would be useful to a reader who will never hire you, because that usefulness is precisely what makes the reader who might hire you trust it. It is the same discipline behind positioning yourself as an expert, scaled up to a few hundred pages.

The economics point the same way the craft does. A median $7,000 outlay against a two-thirds chance of profit is a rare shape for a business investment: the downside is bounded and mostly recoverable, and the tail — 17% of authors clearing more than $250,000 — is one a consulting practice almost never gets to buy into. If the argument is there, the remaining questions are practical ones about turning your expertise into a book and the AI book writing software you draft it in. The scarce input was never the money. It was the ten months.

Ten months is the part you can actually compress. StoryProp keeps your argument, your frameworks and your client stories on the record and drafts from your plain-language direction a piece at a time, so the book gets written in the hours a working practice can spare — and exports clean, under your byline, with no AI notice attached.
