First 6 months of the new book ($48,921.15) // Notes and numbers // Is this your year to write one?
When I was chatting with Sahil about his book, he said (slightly paraphrased):
I don’t care at all about the sales at launch. I care about the sales in 2025.
Which I absolutely love. It’s the long-term view.
(Full convo with Sahil embedded below, or skip ahead for my notes and numbers.)

Most authors put far too much weight on launch performance.
Which makes a perverse sort of sense, since the average nonfiction bestseller hits peak sales within the first 3 months (due to active promotion) and then lose 95% of that peak within the year (due to a lack of recommendability), never to recover (source):

If you expect your book to die after launch, then you’re obviously going to focus pretty heavily on that launch window. But that’s optimizing for failure, because the only books that matter are the books that last.
As a result, I tend to ignore the first 3 months’ sales data for a new book, since those early months aren’t representative of the book’s future. I don’t let strong early sales excite me, nor do I allow weak early sales to upset me.
The data I care about is months 4-6, which is when I finally get to learn whether I’ve written something that will last. (And I don’t care about volume, but about organic growth rate.)
That six-month milestone has just passed for my most recent book, and apart from a slight blip in month 5, the longevity and recommendability are looking promising.
Here’s the Amazon breakdown thus far (with more deets and non-Amazon sales channels below):

The full breakdown is:
- Preorder: $4,042
- Month 1 royalties (Amazon): $2,430.71
- Month 2: $4,254.25
- Month 3: $5,028.21
- Month 4: $6,300.54
- Month 5: $5,645.12
- Month 6: $8,319.32
- Subscription (i.e., paid community atop the book): $12,901 ($1,729 MRR)
Which puts the running total at just shy of $49k (or $36k in “pure” royalties if you exclude the community). I write pretty slowly (and suffer quite a lot while doing it), so if the sales had started to decline after month three, I would have been a bit bummed.
But given that they seem to be growing, I’m optimistic.
My first book, The Mom Test, started out way more slowly than this (i.e., three years to regularly exceed $3k / mo), and that book has now done ~$600k in total royalties (and still growing), which is pretty meaningful.

This one seems to be on a much stronger trajectory.
December also had a couple other exciting milestones. It was the first month where this book sold more than 1,000 copies (1,101) and also the first month where it exceeded $10k in monthly earnings (royalties + subscription). Taken together, the three books are now selling more than 1,000 copies per week, which has been a target of mine for a while now.
So, I partly wanted to share how it’s been going (accountability and transparency and all that), and I partly wanted to contradict the common “wisdom” that books are bad business.
It’s true that most books don’t succeed as products (which obviously also makes the creation of them a bad business). But that’s only because most books are mistakenly built like art (i.e., in secret as an act of solitary genius) instead of like products (i.e., iteratively and humbly while in constant contact with real readers).
If you run a proper process, books are great: great for the income, great for the impact, and great for the intrinsic satisfaction of having written one.
Anyway, I like them. And I hope that if you’ve ever felt the same, that this is the year you write yours.
Maybe you’ll end up liking them too.

This is super inspiring , thanks for sharing this writeup. You've helped me take a look at my (limiting) beliefs around turning a book into meaningful income, so I need to rethink my launch strategy a bit to make sure that I'm doing all I can to not just grow a community of readers and like-minded thinkers, but also focus on longevity and the usefulness of the book (which your book helped me focus on during the writing phase).
I like Derek Sivers' thoughts around marketing, that it can be just as creative as the process of creating the work. Makes me want to think about how to optimize for all these different outcomes.
You know I love to hear that :). Of course, you're still under no obligation to be "optimal" (and you may be optimizing for something other than direct book income, as you mentioned). But in general, yeah, I wouldn't write off the revenue potential of the right book. Another nice bonus is that once the recommendation loop is running, the royalties are 100% pure passive income, which is really hard to get from most product categories.
Interesting article. Love the transparency. A book recommendation for you is PyroMarketing by Greg Stielstra. I just finished it and the author is actually in the publishing business so he references the publishing industry often. It's all about finding those small groups of customers that love your product and then letting the fire grow big over time. Similar to what you were saying in the article.
Shout out to The Mom Test! One of my favorite business books!
Ah, nice one, sounds perfect for me. Will give it a look👀. And great chatting with you the other day -- looking forward to hearing how you get on with it.
Love your new book Rob! I am 100% in sync, and keep learning a lot!
Delighted to hear it and very kind of you to say. Thanks :)
