The Simple Path to Wealth
JL Collins
The Simple Path to Wealth is JL Collins's guide to investing, written as letters to his daughter. Its advice fits in a sentence: avoid debt, spend less than you earn, and invest the difference in broad, low-cost index funds every month for decades without trying to time the market. It explains why most investors fail to beat the market after costs, why crashes are normal, and how F-you money buys the freedom to say no long before full independence.
You have not started investing because it looks like a skill you do not have. Collins wrote this book for a daughter who felt the same and needed to do it anyway. His answer is that the skill you lack is one nobody reliably has, and the path that works does not need it: own everything, cheaply, every month, and do not sell when it is on sale.
The book in essence
Collins's case rests on evidence that most stock-pickers, professional and amateur, trail the overall market over long periods after fees, and that the few who beat it cannot be identified in advance. So he tells readers to stop trying and own the whole market through a broad index fund. It is diversified, so no company's failure matters. It is low cost, which matters because a fee of one or two percent a year, paid over a working life, can leave you with a fifth to a third less money. And it is boring, so there is nothing to watch or trade. Around this he places three behavioural rules. Debt is an emergency, not a normal condition. Market falls, even by half, are the normal weather of the thing you own, and the damage is done by selling in them, not by holding through them. And F-you money, enough savings to walk away from a bad situation, buys the first real freedom long before the crossover into full independence.
The book grew from a series of blog posts Collins began in 2011 and was published in 2016. It is written for an American reader with access to particular funds, and its product advice does not travel. Its principles do: broad, cheap, monthly, held for decades, in whatever instruments are sensible where you live. Nothing in it is advice for your situation, and Collins says so.
Who it's for
- People who have saved something and have no idea what to do with it
- Readers frightened off investing by the noise of stock tips, groups and news
- Anyone who wants the case for index funds made plainly, once, and then left alone
Who it's not for
- — Readers outside the United States who need product-level guidance; take the principles and research the instruments where you live
- — Anyone who wants to pick stocks or time the market; the book's whole argument is against both
Key lessons
01
Few beat the market, so own all of it
Decades of data show that most investors, professional or amateur, trail the overall market over long periods after costs, and that the few who beat it are visible only in hindsight. Collins's conclusion is to stop trying: hold a broad, diversified, low-cost fund that owns hundreds or thousands of companies, and let the economy do the work.
A software tester in Gebze spends two years reading investment forums and switching into whichever fund topped last year's table, each time just after its best year. When she finally compares, a plain broad index fund held the whole time would have left her ahead. She moves the monthly amount into one and deletes the forum app.
02
Cost is the one thing you control
A fund's return is unknown in advance; its fee is printed. A fee that sounds tiny, one or two percent a year, compounds against you for decades: over a forty-year working life it can leave you with a fifth to a third less than a near-zero fee would. Comparing fees is the single most useful thing an ordinary investor can do, and the one most skip.
Two cousins in Ankara invest the same amount every month for twenty-five years, one in a fund charging two percent a year, the other in one charging 0.4 percent. If both funds earn about seven percent before fees, the second account ends roughly a quarter larger. The gap is about half of everything either cousin paid in, and the fee alone created it.
03
Crashes are weather, not news
The market falls, sometimes by half, and this is not a malfunction but the normal behaviour of the thing you own. The investors who lose are those who sell in the fall and buy back in the recovery. A cushion of cash is what lets you watch a fall and keep the monthly order running, which is why it pays to build one before investing seriously.
In March 2020 a civil engineer in Adana watches her broad global fund lose about a third of its value in a few weeks. In her desk drawer is a card she wrote two years earlier: in a crash, I do nothing. She reads it twice, leaves the monthly order running, and by the end of the year the fund is above where it started.
04
F-you money buys freedom early
Long before investment income covers your life, a smaller sum is enough to say no: to leave a job that is harming you, refuse a transfer, or take months to find the right next thing. Collins counts this freedom among the most valuable things money can buy. He sets no fixed figure; for many readers, it begins at around a year of expenses.
A hotel accountant in Antalya is asked to move to a branch in another city, far from her ageing parents. Ten months of expenses sit in her savings and her fund. She declines the transfer, and when the hotel lets her go she takes three months to find work close to home. The money did not make her rich; it made the no possible.
