Yes, it’s true: Bill Gates reads about 50 books a year, roughly one a week, and he’s said so consistently since telling the New York Times in 2016 that reading is “the main way that I both learn new things and test my understanding.” Nearly a decade later, he’s still at it. But the number is the least useful part of the story. What actually makes it repeatable is a short list of specific, almost boring habits: how long he sits down for, what format he reads in, and when he decides a book is worth notes.

The Habit Behind the Number
Gates has told the same basic story to the New York Times, Time, and Quartz over the years, and it hasn’t changed much. He reads mostly nonfiction: biography, history, science, public health, and the occasional novel his wife or a friend hands him. He picks up a book expecting to learn something, not just to relax, though he’s said reading before bed also helps him wind down.
What’s easy to miss in the “50 books” headline is that this isn’t a sprint he does once a year. It’s a weekly baseline he’s maintained since at least the mid-2010s, through running Microsoft, launching a foundation, a divorce, and turning 70. The habit outlasted the job.
The Four Rules That Actually Do the Work
In a widely cited 2017 Quartz interview, Gates laid out four specific habits that let him get through that much material without it feeling like homework.
He blocks at least an hour, not fifteen-minute chunks. Gates has said that with a book, especially nonfiction, he wants to sit down for an hour at a stretch. Shorter content like articles or videos fits into small gaps in the day; a book, in his view, doesn’t.
He reads on paper, not a screen. This is partly about focus and partly about the notes (see below). A physical book is harder to swipe away from than a tab.
He finishes what he starts, on principle. Gates has said he refuses to abandon a book partway through, even ones he actively dislikes, citing his years-long standoff with the 1,000-plus-page “Infinite Jest” as the extreme example. The more he disagrees with an author, the longer the book takes him, because he stops to argue in the margins.
He takes notes, but only on some books. This is the detail most articles about Gates and reading leave out. He’s said directly that he only writes notes on roughly one in five of the books he reads, doubling the time those particular books take. Notes aren’t a blanket rule; they’re reserved for the books he wants to actually retain or argue with. For everything else, he just reads.
That last point matters because it’s the opposite of what most “read like a billionaire” advice implies. Gates isn’t annotating every page of every book. He’s decided in advance which books earn that effort and let the rest be lighter reading.
What “50 Books a Year” Actually Requires
Most coverage repeats the 50-books figure without ever translating it into something you can act on. Here’s the math, using an average nonfiction book at roughly 300 pages.
Fifty books a year works out to about 41 pages a day, or close to 300 pages a week. How long that takes depends entirely on your reading speed, which varies a lot more by book than most people assume: a breezy memoir reads faster than a dense policy book, regardless of who’s reading it.
| Your rough pace | Time to read 41 pages | What that gets you over a year |
|---|---|---|
| 20–25 pages an hour (dense or unfamiliar material) | About 100 minutes a day | Roughly 30–35 books |
| 35–40 pages an hour (typical adult pace on an average nonfiction book) | About an hour a day | Close to 50 books |
| 50–60 pages an hour (fast reader or a page-turner) | 40–45 minutes a day | 55–65+ books |
That middle row is worth noticing: at an ordinary reading pace, hitting Gates’s number takes almost exactly the “at least an hour” block he already builds into his rule. The math backs up the habit. It also means 50 books a year isn’t really about reading unusually fast; it’s about reading for roughly an hour a day, most days, for a full year. One of our team clocked their own pace on a typical nonfiction book recently and landed at about 35 pages an hour, which lined up almost exactly with this table before we’d built it.
If an hour a day sounds like more than your week can absorb, the target can flex without losing the habit. Twenty books a year is a book every two and a half weeks, at roughly 25 minutes a day. Twelve is a book a month. The specific number matters far less than whether the daily block actually happens.
“Think Week” Is a Different Habit, and People Mix the Two Up
A lot of the content about Gates and reading blends his personal 50-books-a-year habit with his “Think Week,” and they’re not the same thing. Think Week was a twice-yearly, week-long retreat Gates took to a cabin in the Pacific Northwest during his years running Microsoft, where he’d read dozens of internal papers and memos from employees, sometimes for most of the day, and send feedback afterward. It shaped real decisions, including Microsoft’s early push into the internet in the 1990s.
That’s a work practice built around technical documents and strategy, done alone, twice a year. His 50-books habit is a daily reading practice built around nonfiction and memoir, done at home, most nights. Both involve a lot of reading. Only one of them is realistic to borrow for an ordinary week, and it’s the daily one, not the cabin retreat.
When He Actually Reads
Gates has said his evenings usually include at least an hour of reading before he goes to sleep, separate from work. On vacation, that expands considerably: he told a Reddit AMA that he gets through about three hours of reading a day when he’s away, which is part of why he’s known for packing a tote bag of books on trips.
He also treats reading as something worth checking in on publicly. Twice a year, he posts a short list of five books on his blog, Gates Notes, once for summer and once around the winter holidays, along with a few lines on why each one stuck with him. It functions less like a top-ten list and more like a periodic review of what he’s actually gotten out of his reading, which is a habit worth stealing even without the audience.
A Scaled-Down Version You Could Actually Keep
Most people don’t need Gates’s specific rules; they need a version sized to an actual week. Here’s what that looks like, built from the habits above.
- Pick one book at a time. Gates reads one at a time rather than juggling several, which removes the “which one was I on again” friction that kills a lot of reading habits before they start.
- Protect a smaller block than an hour. Twenty to thirty minutes, same time each day, beats an hour you can’t consistently find. Right after dinner or during a commute both work.
- Decide your note-taking rule ahead of time, not mid-book. Following Gates’s own ratio, save notes for the one book in five you actually want to remember or argue with. Everything else can just be read.
- Give yourself permission to abandon a book. This is the one rule of Gates’s worth skipping. His “always finish” habit works for someone who’s already fast and selective about what he starts. For most people, forcing through a book you’re not getting anything from is exactly the kind of friction that ends the habit altogether.
One of our team tried the full hour-before-bed version for a week, the way Gates describes it, and found it pushed their actual lights-out time later than planned most nights. Twenty minutes right after dinner, before phones came out, turned out to be the version that actually lasted past the first week.
Questions Readers Ask About Gates’s Reading Habit
How many books does Bill Gates read a year? About 50, a figure he’s repeated in interviews from 2016 through his more recent public comments, working out to roughly one book a week.
Does Bill Gates read fiction, or only nonfiction? Mostly nonfiction, covering topics like public health, biography, history, and technology, but his twice-yearly reading lists usually include at least one or two novels or memoirs.
What time of day does Bill Gates read? Mainly in the evening, for at least an hour before bed. On vacation, he reads considerably more, up to three hours a day by his own account.
What is Bill Gates’s “Think Week”? A separate, twice-yearly retreat he took during his Microsoft years to read internal strategy papers and memos in isolation. It’s a work practice, distinct from his personal 50-books-a-year reading habit.
Start With the Block, Not the Number
The specific habit worth copying isn’t “read 50 books.” It’s “read for a set block of time, most days, and only take notes on what deserves it.” Pick a block your actual evening can hold, even if it’s a third of Gates’s hour, and let the book count take care of itself. If you want a simple way to see whether the habit is sticking, our daily routine template already has a column built for tracking pages read, which is a lighter lift than counting finished books until the habit is a few months old.
