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.

The boom in casual footware ushered in by the pandemic has ended, a potential problem for companies such as Adidas that benefited from the shift to less formal clothing, Bank of America says.

The casual footwear business has been on the ropes since mid-2023 as people began returning to office.

Analyst Thierry Cota wrote that while most downcycles have lasted one to two years over the past two decades or so, the current one is different.

It “shows no sign of abating” and there is “no turning point in sight,” he said.

Adidas and Nike alone account for almost 60% of revenue in the casual footwear industry, Cota estimated, so the sector’s slower growth could be especially painful for them as opposed to brands that have a stronger performance-shoe segment. Adidas may just have it worse than Nike.

Cota downgraded Adidas stock to Underperform from Buy on Tuesday and slashed his target for the stock price to €160 (about $187) from €213. He doesn’t have a rating for Nike stock.

Shares of Adidas listed on the German stock exchange fell 4.5% Tuesday to €162.25. Nike stock was down 1.2%.

Adidas didn’t immediately respond to a request for comment.

Cota sees trouble for Adidas both in the short and long term.

Adidas’ lifestyle segment, which includes the Gazelles and Sambas brands, has been one of the company’s fastest-growing business, but there are signs growth is waning.

Lifestyle sales increased at a 10% annual pace in Adidas’ third quarter, down from 13% in the second quarter.

The analyst now predicts Adidas’ organic sales will grow by a 5% annual rate starting in 2027, down from his prior forecast of 7.5%.

The slower revenue growth will likewise weigh on profitability, Cota said, predicting that margins on earnings before interest and taxes will decline back toward the company’s long-term average after several quarters of outperforming. That could result in a cut to earnings per share.

Adidas stock had a rough 2025. Shares shed 33% in the past 12 months, weighed down by investor concerns over how tariffs, slowing demand, and increased competition would affect revenue growth.

Nike stock fell 9% throughout the period, reflecting both the company’s struggles with demand and optimism over a turnaround plan CEO Elliott Hill rolled out in late 2024.

Investors’ confidence has faded following Nike’s December earnings report, which suggested that a sustained recovery is still several quarters away. Just how many remains anyone’s guess.

But if Adidas’ challenges continue, as Cota believes they will, it could open up some space for Nike to claw back any market share it lost to its rival.

Investors should keep in mind, however, that the field has grown increasingly crowded in the past five years. Upstarts such as On Holding and Hoka also present a formidable challenge to the sector’s legacy brands.

Shares of On and Deckers Outdoor , Hoka’s parent company, fell 11% and 48%, respectively, in 2025, but analysts are upbeat about both companies’ fundamentals as the new year begins.

The battle of the sneakers is just getting started.
