Money Buys Happiness, Even if You’re Already Rich

A big raise provides significant boosts in happiness even at household incomes of $500,000, according to a new research report.

A wealth of research has long shown that more money makes a big difference to people with low pay, moving them from insecurity to stability. Above that level, the effect is often assumed to be much smaller.

But according to a paper by Matt Killingsworth , a senior fellow at the University of Pennsylvania’s Wharton School, the bonuses and leaps in income high earners reap are so large that they keep adding to well-being in the same way that smaller pay bumps do at lower tiers of earnings.

“I think of this as a ladder across society. The rungs are separated by more and more dollars, but exactly the same amount of happiness,” said Killingsworth, who published his report on his Happiness Science website.

An academic paper in 2010 popularised $75,000 as the salary threshold beyond which earning more money didn’t make people any happier. More recent research indicates that there is no such plateau.

Killingsworth and other researchers stress that many things influence human happiness, including your relationships, your job and the country you live in.

“No single factor, including money, dominates the equation,” Killingsworth said.

Previous studies on money and happiness have consistently demonstrated two things: that richer people are happier, and that it takes progressively more money to keep generating a well-being boost of a given size.

Killingsworth says that many people draw the wrong conclusion from that latter finding. They assume that money makes the biggest difference on Americans’ happiness at lower levels of income.

His paper suggests this assumption is wrong. That is because earnings surge exponentially across the income distribution, offsetting money’s diminishing returns on happiness even at the high end.

The lowest-earning 20% of U.S. households on average brought in about $23,000 before taxes in 2021, and the middle 20% earned about $87,000, according to the latest data from the Congressional Budget Office. The top 20% averaged roughly $418,000, with the very highest earners making significantly more than that.

“It could be entirely reasonable for an individual to continue aspiring to climb one more rung in the income ladder” to pursue happiness, Killingsworth writes in his paper.

Even Americans earning a lot of money wish they could do just that. Last year, survey respondents with incomes of $200,000 or more said that the median income they would need to be happy and less stressed was $350,000, according to data from the financial-services company Empower.

More money doesn’t guarantee more happiness. The side effects vary. Some who receive big raises later report big letdowns. Others who voluntarily take a pay cut say they are glad they did.

Millennial women’s wealth is outpacing men’s as a new generation inherits and grows their assets at a wider scale than ever before, according to RBC Wealth Management.

In a survey of roughly 2,000 men and women with at least $1 million in investable assets, millennial women respondents had an average of $4.6 million, compared with $3.8 million for women of all age groups and $4.5 million for all men.

Inheritance is one part of the picture, as baby boomers are expected to transfer $124 trillion to the next generation, but so is the progress millennial women have made in the world of business, investment and lucrative professional careers as they close the gap with men.

“Millennial women are catching up, or have outpaced the males as far as their wealth building,” said Angie O’Leary, head of wealth strategies at RBC. “We know that’s coming from a more diversified set of investments, such as entrepreneurship, real estate and of course, investments [in financial markets].”

Millennial women, now in their 30s and 40s, tend to differ from earlier generations of women more than they do from men in terms of their source of wealth. While investments were the largest driver of wealth across all categories, millennial women cited business ownership, innovation, and executive roles far more than Gen X or boomer women.

More than 60% of millennial women cited business ownership and more than 40% mentioned executive roles, but neither exceeded 22% for either Gen Xers and Boomers. Younger women also grew their fortunes from professional sports or arts 39% of the time, compared with just 6% and 1% for Gen Xers and Boomers, respectively.

In terms of inheritance, the gap between generations was smaller. About 37% of men and 35% of women cited family money as a source of wealth overall, breaking down to 44% of millennials, 30% of Gen X and 33% of boomer women.

With women controlling so much wealth, their spending and investments as a group are evolving and extending into areas previously considered stereotypically male such as real estate, cars and watches, O’Leary said. “Women are starting to look a lot like their male counterparts when it comes to investments, real estate, philanthropy,” she said. “That’s a really interesting emerging female economy.”

In real estate, for example, single women made up 20% of home buyers in 2024 up from 11% in 1981, when the National Association of Realtors began tracking the data. By contrast, single men make up 8% of the market and have never exceeded 10%, according to NAR.

While men and women shared largely similar priorities overall in terms of well-being, relationships, legacy and personal drive, younger generations of women were successively more likely to value drive and personal power, and successively less likely to rank relationships and social bonds—though that could also be a function of age and stage of life.

“This generational shift suggests evolving societal norms and responsibilities, where younger women seek personal achievements, while older cohorts value nurturing connections and community stability, affecting their financial and lifestyle choices,” the report said.
