The Millionaire Next Door

Thomas J. Stanley and William D. Danko · 1996

Thesis

Most American millionaires are not the high earners who look rich but ordinary, frugal people, often owners of unglamorous businesses, who accumulated wealth by living well below their means, and the habits of spending, saving and family support that separate them from equally well-paid people who never become wealthy can be measured and copied.

The main ideas

Wealth is not the same as income. Many high earners have little wealth; many millionaires have modest incomes.
The typical millionaire is a self-made business owner who lives in an ordinary house and spends little on status goods.
A simple formula predicts expected wealth from age and income, separating prodigious accumulators from under accumulators.
Financial independence matters more to millionaires than displaying social status.
Gifts from parents to adult children, which the authors call economic outpatient care, reduce the children's own accumulation.
Many millionaires chose unglamorous, profitable businesses and spotted market opportunities others ignored.

Wealth is not income

Thomas Stanley and William Danko, marketing professors who had studied the affluent for two decades, surveyed households in wealthy areas between 1995 and 1996 and combined the results with interviews and earlier research. About 385 of the respondents had a household net worth of $1 million or more.

Their portrait of the typical millionaire contradicts the popular image. He is 57 years old, married with three children, and about 80 percent of millionaires are first-generation affluent, not heirs. Self-employed people make up fewer than 20 percent of American workers but two-thirds of millionaires. The median household in the sample was worth about $1.6 million, while its median realized income was about $131,000 a year.

The book's central distinction is that wealth is not the same as income. A household that earns a high income and spends it remains without wealth; a household that earns a moderate income and invests the difference over decades becomes rich.

Implication: measure financial progress by net worth, not salary, and do not assume that people who spend like the rich are rich.

Frugal, frugal, frugal

The authors found that millionaires spend little on the goods that signal status. Half of those surveyed had never spent more than $399 on a suit, $140 on a pair of shoes or $235 on a watch. Most lived in ordinary houses and drove ordinary cars; a chapter is titled "You Aren't What You Drive."

The opposite type the authors call "Big Hat, No Cattle," a Texan expression for people who look wealthy but own little: high earners whose spending on homes, cars and clothes consumes their income.

The mechanism is that status spending is never finished. People who define success by visible consumption compare themselves with ever-wealthier neighbors and keep spending; those who define it by independence keep saving. Millionaires, in the authors' account, budget carefully and spend more time planning their investments than under accumulators do.

Implication: decide whether you want to look rich or be financially independent, because on an ordinary income you cannot do both.

The wealth formula

Stanley and Danko offer a rule of thumb for expected net worth: multiply your age by your realized pretax annual household income, then divide by ten, excluding any inheritance. A 30-year-old earning $50,000 a year should be worth about $150,000.

People with twice the expected figure or more they call prodigious accumulators of wealth; those with half or less are under accumulators; those in between are average. Prodigious accumulators typically hold about four times the wealth of under accumulators of the same age and income.

The mechanism is that, at any given income, differences in wealth come from choices about spending and investing, so comparing people of similar age and income isolates those choices.

Implication: calculate your own expected net worth by the formula, and if you fall well short, look at your spending rather than your income.

Economic outpatient care

The authors call gifts of money and other help from parents to adult children and grandchildren economic outpatient care. Their finding is that the more such help adult children receive, the less wealth they accumulate themselves.

In a chapter titled "Affirmative Action, Family Style," they argue that parents tend to give the most help to the child who is least successful financially, which reduces that child's incentive to become self-sufficient and weakens the weak. The adult children of millionaires who become self-sufficient, the authors found, are generally those who received the least such support.

The mechanism is that regular subsidies change behavior: recipients spend at a level their own incomes cannot sustain and do not build the habits of saving.

Implication: help adult children in ways that build their independence, such as education, rather than by subsidizing their spending.

Find your niche

Many of the millionaires surveyed owned what the authors call dull-normal businesses: welding contractors, auctioneers, rice farmers, owners of mobile-home parks, pest controllers and paving contractors. These businesses are unglamorous, so they attract less competition, and their owners keep much of what they earn.

The authors argue that millionaires are proficient in targeting market opportunities and chose the right occupation. A final chapter compares self-made millionaires with heirs, who are more often found in high-status but lower-accumulating professions.

Implication: when choosing work or a business, weigh how much of the income you will be able to keep and invest, not how impressive the work appears.

Limits

It studies only those who became rich. In Fooled by Randomness, Nassim Taleb argued that the book suffers from survivorship bias, ignoring people who behaved the same way without becoming wealthy, and that its subjects held assets such as stocks during an unusually strong bull market.
Its sample is small and self-reported. The findings rest on about 385 millionaires in affluent areas, answering questions about their own behavior, so they show associations rather than causes.
Its figures date from the mid-1990s. Costs of housing, education and health care have since changed, and Stanley's later work and the 2018 sequel by his daughter, Sarah Stanley Fallaw, updated the numbers.

The Dhandho Investor — another account of ordinary business owners building wealth through low costs and patience.
Fooled by Randomness — the argument that studies of the successful mistake luck and survivorship for method.
