The honest answer is that the median is very low and the average is meaningless, because a handful of enormous earners drag it upward. Most published authors do not make a living from books. Most authors who do make a living have many books, not one good one.
That is the frame. Here is the actual arithmetic, because the arithmetic is knowable even when the outcome is not.
Self-publishing royalties
On Amazon KDP, ebook royalties are the number everybody quotes:
- 70% on ebooks priced between $2.99 and $9.99, minus a delivery fee based on file size.
- 35% below $2.99 or above $9.99.
A $4.99 ebook at 70% earns you roughly $3.40 after delivery costs. A $2.99 ebook earns about $2.00. This is why so much genre fiction sits at $4.99: it is close to the top of the range where the higher rate applies, and readers are used to it.
Print is different. Paperback royalties are 60% of list price minus printing cost, and the printing cost is real. A 300-page paperback at $12.99 might return around $3.00 to $4.00. Longer books cost more to print and earn less, which is worth knowing before you write a 700-page debut.
Page reads through Kindle Unlimited pay from a shared monthly pot, which historically works out around half a cent per page. A 300-page book read in full earns roughly the same as a modest sale. That makes KU excellent for prolific series writers and mediocre for a single standalone.
Getting the pricing, categories and listing right matters more than most authors expect. Amazon KDP keywords and categories covers the part you control.
Traditional publishing royalties
Lower rates, but somebody else pays the costs.
- Hardcover: around 10% to 15% of list price, usually escalating with volume.
- Paperback: around 7.5%.
- Ebook: around 25% of net receipts, which is not the same as 25% of the price.
If you have an agent, they take 15% of everything.
How advances actually work
An advance is a loan against future royalties, paid in instalments. Typically on signing, on delivery of the manuscript, and on publication, sometimes split further. A "$30,000 advance" is not $30,000 arriving this year.
You earn out when accumulated royalties exceed the advance. Only then do you see another payment. Most books never earn out, which is normal and not a scandal: the publisher priced the advance as its estimate of total earnings.
Typical debut advances for fiction sit in the low thousands to the low tens of thousands, and the six-figure deals that get announced are announced precisely because they are unusual.
The comparison that actually matters
For a $4.99 ebook:
- Self-published: about $3.40 per sale.
- Traditionally published: about $0.87 per sale, before the agent's cut.
You need roughly four times the sales through a traditional deal to earn the same money. What you get in exchange is an advance paid up front regardless of sales, professional editing and cover design, bookshop distribution, and no upfront cost or risk.
The real trade is money per copy against copies sold and risk carried. Neither is obviously right, and the answer depends heavily on whether your book needs physical bookshops to find its readers.
What it costs to publish a book yourself
Self-publishing is not free. Reasonable ranges:
| Item | Typical range |
|---|---|
| Cover design | $100 to $800 |
| Copy edit | $500 to $2,000 |
| Proofread | $200 to $700 |
| Formatting | $0 to $300 |
| ISBN | $0 to $125 |
| Launch advertising | $0 to whatever you allow |
Most first books do not recover this. Plan for that rather than being surprised by it, and consider spending the money where it converts: the cover, the blurb and the copy edit, in that order.
What actually moves the number
Volume. Almost every author earning a living has a backlist. One book is a lottery ticket; twelve books in a series is a business.
Series. Book one sells books two through six. Standalone titles start from zero every time. This is the single largest structural factor in author income and it is a decision you make before you write, which is why how to write a book series is worth reading early.
Genre. Romance, thriller and litRPG readers consume enormously and buy frequently. Literary fiction readers buy fewer books and read them slowly. This is not a judgement about quality, just about how the money moves.
Rate of release. Readers forget. Authors publishing several times a year compound their audience; authors publishing every three years restart it.
Rights beyond the book. Audio, translation and large-print rights are genuine income and are routinely ignored by self-publishers. Turning your book into an audiobook is the most accessible of these.
The honest summary
If you want to make money from writing, the strategy that works is unglamorous: pick a genre with hungry readers, write a series, publish consistently, get the covers and blurbs right, and keep going for several years.
If you want to write one particular book because it is the book you want to exist, that is a completely legitimate reason. Just do not fund it with money you need.
When the book is ready, how to sell your first 100 books covers the part that actually moves early copies, and how to self-publish a book covers the mechanics.
