How Many Low Content Books Do You Need to Make Money?

There's no number that guarantees an income

If you're searching for "how many low content books do I need to make money," you want a formula: publish X titles, earn $Y a month. That number doesn't exist, and no honest source can give it to you. Amazon doesn't publish how many copies any individual book sells, so nobody — not Amazon, not a course seller, not a calculator — can tell you what an "average" low content book earns per month.

What you can work out, precisely, is your royalty on a single copy once it sells. That's the honest starting point: know your per-copy economics first, then decide how many titles you're willing to produce, knowing that how many of them sell is outside your control and outside anyone's ability to predict.

What you can actually calculate: royalty per copy

KDP's paperback royalty is a fixed formula: (royalty rate × list price) − printing cost. The rate itself depends only on your list price — there's no separate "royalty plan" to pick for print, the way there is for Kindle eBooks (that's a 35%/70% choice, a different, eBook-only setting). For paperbacks sold through Amazon's own store, the rate is 50% at or below $9.98, and 60% from $9.99 up.

Printing cost depends on trim size and page count. KDP calls a trim up to 6.12 x 9 inches "regular" — that's flat $2.30 (US, black ink) for any book between 24 and 110 pages, then $1.00 plus $0.012 per page above that. The popular 8.5 x 11 low content trim counts as "large": flat $2.84 for 24-110 pages, then $1.00 plus $0.017 per page.

Run a few realistic combinations through that formula and the picture gets concrete fast:

Two things jump out. Pricing above $9.99 lifts you into the 60% royalty band instead of 50% — on the 100-page regular-trim example, moving from $6.99 to $9.99 takes the royalty from $1.20 to $3.69, though that jump reflects the higher list price as well as the rate change, not the rate change alone. And extra pages past 110 add to your printing cost — $0.012 a page on regular trim, $0.017 on large trim — which is why the 120-page large-trim book above earns $0.20 less per copy than the 110-page version at the same price. You can run your own book's numbers on our KDP royalty calculator and printing cost calculator.

Expanded Distribution changes the channel, not the math in your favor

Expanded Distribution is a free, optional enrollment that puts your paperback in front of bookstores, libraries and academic institutions through Amazon's US and UK distributors. It pays a flat 40% of list price minus printing cost — regardless of your price band — and it's paperback-only; hardcover isn't eligible. At $9.99 on the 110-page large-trim book above, that's $1.16 a copy, well under the $3.15 you'd earn on an Amazon-channel sale of the same book. Enrolling is free and there's no guarantee of acceptance or orders through it — treat it as an extra channel for copies you wouldn't otherwise sell, not as a better rate.

Why you can't plug in a "sales per title" number

This is the honest boundary, not a workaround: Amazon does not publish a sales-by-title feed or a bestseller list ranked by exact units. The only public signal for any individual book is its Best Sellers Rank (BSR) — and BSR is a relative, constantly shifting rank against every other title in its category, not a sales count. There is no verified "average low content book sells N copies a month" figure anywhere, because Amazon has never released the data that number would require.

That means "royalty per copy times average monthly sales times number of books" isn't a formula you can honestly fill in — the middle term doesn't exist. A BSR-based estimator can give you a rough range for a book that's already published and already ranking (try our BSR-to-sales estimator), but it can't tell you what an unpublished title will do, and it's an estimate interpolated from public reference points, not a measurement.

So what the question actually turns into

Since demand per title isn't predictable, the honest version of "how many books do I need" isn't a target count — it's two things you actually control:

• Your economics per copy. Price above $9.99 where the market supports it, keep regular-trim books at or under 110 pages when you can, and know your exact royalty before you publish rather than after.
• How many titles you can sustainably produce and keep listed. Publishing itself costs nothing upfront on KDP — Amazon deducts the printing cost from each sale, not from you. Your real costs are optional: an ISBN (KDP gives you a free one), proof copies (print cost plus shipping), and your own time building interiors.

That second point is the practical constraint, not motivation or "the right niche": building interiors by hand is slow, and that speed caps how many titles you can realistically get listed. A tool like our KDP Creator generates print-ready 300-DPI page sets — sudoku, word search, maze, math, number-fill, crossword and word-scramble — as a ZIP with a manifest, so you assemble your interior faster; it doesn't output a finished PDF, and it doesn't touch pricing, page count, or trim size — the variables that actually set your royalty.
