The Simple Path to Wealth

Letters to a daughter who found money boring

JL Collins spent decades in business, took several years off work along the way, and reached financial independence without a high salary. He started a blog in 2011 to write down what he knew for his daughter, Jessica, who had told him that money was boring and that she did not want to spend her life thinking about it. The blog's Stock Series became popular in the financial independence community, and in 2016 he turned it into this book. The foreword is by Pete Adeney, who writes as Mr. Money Mustache.

Collins's premise is that his daughter's attitude is right. Most people should not spend their lives thinking about money. The point of wealth is freedom, and the way to get it is simple enough to fit on an index card. He admits that it took him decades and several expensive mistakes to learn it. He picked stocks. He bought actively managed funds. He hired advisors. He bought houses he thought were investments. The book is the shortcut he wishes he had been given at twenty.

The plan has three parts. Avoid debt. Spend less than you earn and invest the difference. Put the investment in a broad, low-cost stock index fund and leave it there. The rest of the book explains why each step works and how to handle the fear that makes people abandon it. The advice is written for a US reader: the funds, tax-advantaged accounts and retirement rules are American, and readers elsewhere have to translate.

Debt and F-You Money

Collins treats debt as an emergency. He does not see it as a normal tool for managing cash flow but as a condition that must end before anything else begins. Credit card and consumer debt at high interest rates should be paid off immediately, because no investment reliably beats their cost. He is willing to tolerate a mortgage or low-rate student loans while investing, but only when the rate is low and the loan is small relative to income. His rule is that if the interest rate is above a few percent, pay the debt first.

The second idea is F-You Money. Collins borrows the phrase from James Clavell's novel Noble House and defines it as enough savings to walk away from a job, a boss or a situation you do not want. It does not have to be enough to retire. His first F-You Money was a few months of expenses, and he used it to take time off and to negotiate from strength. Money, in his telling, buys freedom before it buys anything else. The sooner you have a cushion, the sooner you can say no.

He argues that the most powerful lever is the savings rate, not the return. A person who saves half of their income reaches independence in about seventeen years regardless of how much they earn. Spending less has a double effect: it increases the amount invested and reduces the amount needed to live on later. Collins is not an extreme frugalist, but he treats every recurring expense as a claim on future freedom.

The market always goes up

The central argument of the stock chapters is that the stock market, measured over decades, always rises, and that the crashes along the way are not exceptions to this but part of it. Collins walks through the history. The 1929 crash and the Great Depression took the market down about 90 percent. The 1970s brought stagflation. October 1987 saw a one-day drop of more than 20 percent. The dot-com bust and the 2008 financial crisis each cut the market roughly in half. In every case, the market recovered and went on to new highs. An investor who held through all of it did well. An investor who sold at the bottom did not.

He gives two reasons for the long-term rise. First, a total stock market fund is a share of thousands of real businesses, staffed by people working every day to make them more valuable. Second, the index is self-cleansing. Companies that fail shrink in the index and drop out. Companies that grow take their place. The index cannot go to zero, because it always holds whatever is succeeding. A single stock can go to zero, and many do.

Collins is blunt about the price of these returns. Crashes will happen, probably several in an investing lifetime, and nobody knows when. The investor's job is not to predict them but to expect them. He describes the market as a wild and powerful ride that rewards people who stay on. The question is not whether you can time the exits, because you cannot, but whether you can hold on.

Why nobody beats the index

Collins devotes several chapters to the ways people lose money by trying to do better than the market. He cites the research showing that most actively managed mutual funds underperform their index over long periods, and that the few that beat it in one period rarely do so in the next. Picking stocks is harder still. Professionals with full-time research staffs fail at it, so a person with a job and a family has no reasonable chance.

The culprits are costs and behavior. An actively managed fund charging one percent a year takes a large share of returns over decades, because the fee compounds too. Collins shows how a few tenths of a percent in fees, or an advisor's one percent on assets, consumes a large part of the final sum. Behavior is worse. People buy when prices are high and the news is good, and they sell when prices are low and the news is bad. Collins calls this the way most investors underperform the very funds they own.

He is especially critical of financial advisors. Most are paid by commission, by a share of assets, or by both, so their incentives point toward complex products and frequent changes. He allows for fee-only advisors paid by the hour for a specific question, but argues that the plan in the book needs none.

His answer is John Bogle and Vanguard. Bogle created the first index fund for retail investors in 1976, and Vanguard is owned by the funds it runs, so its interests align with its investors rather than with outside shareholders. Collins's fund of choice is VTSAX, the Vanguard Total Stock Market Index Fund, which holds nearly every publicly traded company in the United States at a very low cost. He says that an equivalent total market fund from another low-cost provider, or the ETF version, works as well.

He addresses international funds and decides against them. Large US companies already earn much of their revenue abroad, so VTSAX gives international exposure. He acknowledges that many sensible investors disagree and hold an international fund as well. He also addresses dollar cost averaging and argues that investing a lump sum at once beats spreading it out, because the market rises more often than it falls, though he admits the slower route is easier on the nerves.

Two stages: building and keeping

Collins describes two stages of investing life. In the wealth accumulation stage, you have income from work and are adding to investments. He recommends 100 percent stocks, all in the total market fund. Volatility does not matter, because you are buying through the dips and will not need the money for years. A crash is a sale.

In the wealth preservation stage, you are living on the portfolio. Here he adds bonds, through VBTLX, the Vanguard Total Bond Market Index Fund, to smooth the ride. His own allocation at the time of writing was about 75 percent stocks and 25 percent bonds, and he suggests somewhere between that and an even split depending on tolerance for drops. He also keeps a small cash reserve. Bonds, he explains, earn less but fall less, and they let a retiree avoid selling stocks at the bottom.

The stages are not strictly tied to age. Someone with a secure pension can stay aggressive. Someone who has stopped working early needs the cushion. He also notes that the stages can reverse: a retiree who goes back to work returns to accumulation.

On withdrawal, Collins relies on the 4 percent rule, which comes from the Trinity study of historical returns. A retiree who withdraws 4 percent of the starting portfolio in the first year and adjusts for inflation after that has, historically, been very unlikely to run out of money over thirty years. Collins is comfortable with 4 percent and suggests that anyone who stays flexible, cutting spending in bad years, can go a little higher. The rule also gives the target: twenty-five times annual expenses.

Accounts, taxes and the rest

Collins walks through the US system of tax-advantaged accounts and how to use them in order. The employer 401(k) or 403(b), at least up to any match, which he treats as free money. The health savings account, which is triple tax-free when used for medical costs. Traditional and Roth IRAs, with the choice depending on current versus expected future tax rates. Then ordinary taxable accounts for whatever is left. He explains required minimum distributions, which force withdrawals from traditional accounts after a certain age, and the Roth conversion ladder, a method early retirees use to move money from traditional to Roth accounts over several low-income years to avoid penalties.

He spends a chapter on Social Security, arguing that it will survive in some form and that most people should delay claiming to raise the monthly benefit. He covers target retirement funds as an acceptable one-decision alternative for people who want the bond allocation handled for them. He discusses the choice between a 401(k) plan with poor funds and a taxable account, and he explains how to read an expense ratio.

Two chapters are opinions many readers argue with. One is on houses. Collins argues that a house is not an investment but an expensive consumer item, and he gives a method for comparing the full cost of owning against renting, including taxes, maintenance, transaction costs and the return the down payment would earn in the market. He has owned houses and does not say never to buy, but he says to buy for lifestyle reasons and to know the price. The other is on charitable giving, where he describes using a donor-advised fund to give appreciated shares efficiently.

Staying the course

The book ends where it began: the plan is simple, and the difficulty is emotional. Collins recalls living through the 1987 crash, when the market lost more than 20 percent in one day, and the fear it produced, and he says that crashes like it taught him to stop reacting. He gives a short set of rules for bear markets. Do not sell. Keep buying if you are in the accumulation stage. Do not watch the news. Remember that every past crash looked like the end of the world at the time.

He also warns about the industry built around complexity: newsletters, trading platforms, hot funds and people who claim to know what comes next. Their business depends on activity. The investor's advantage is inactivity. The last chapters give a one-page summary of the path and a reading list that is mostly Bogle.

What the critics say

The book is written for Americans. Its funds, accounts and retirement rules do not transfer, and readers elsewhere have to find their own equivalents. Many investors disagree with the single-country, single-fund approach, since a US-only portfolio bets on one market and the past century of US returns may not repeat. The 100 percent stock allocation suits people with strong nerves and long horizons, and some planners consider it too aggressive. The 4 percent rule assumes a thirty-year retirement and historical US returns, so early retirees and investors in other markets may need a lower rate. The chapters repeat each other, which shows their origin as blog posts.

Who should read it

Read it if you want one plan you can follow without checking the market, and especially if you are early in your career and have not yet built habits around debt and spending. It is US-centric: the funds, 401(k) and IRA rules, Social Security and tax chapters are American, so readers in other countries should take the principles and look up local equivalents.
