I used to repeat this at dinner parties. I’d lean back, take a sip of something, and drop the fact like it was my own discovery: You know, once you hit $75,000, more money doesn’t make you happier. People nodded. If $75,000 was the ceiling, then I was already fine. No need to push harder.
I half-believed it for years. It’s the Great Wall of China of happiness studies: everyone “knows” it’s true, but it’s not true, much like the myth that the Wall is visible from space. The Wall isn’t visible from space, and $75,000 isn’t the magic happiness number. The story is more interesting, more useful, and a lot more honest than the comfortable fact I was repeating.
Key Takeaways
The 2010 Kahneman-Deaton study found that day-to-day mood flattens around $75,000, but life satisfaction keeps rising — the pop version ignored that distinction.
The 2021 Killingsworth smartphone study contradicted the plateau, finding no ceiling. An adversarial collaboration in 2023 resolved the conflict by splitting the data: for 80% of people, happiness keeps rising past $100,000; only the unhappiest 15–20% see a plateau near $100,000 (the original $75,000 adjusted for inflation).
Money’s effect on happiness is real but modest — a four-fold income difference matters less than a headache, about as much as being a caregiver, and twice as much as being married.

What the 2010 Kahneman-Deaton study actually found
The 2010 study is the source of the famous $75,000 threshold, but its findings were more nuanced than the popular takeaway suggests. The author hypothesizes Kahneman and Deaton anchored to a median professor salary of $75,000 in 2010, which could have influenced the threshold they identified.
The original finding
In 2010, Daniel Kahneman and Angus Deaton at Princeton analyzed over 450,000 survey responses from Americans. Their headline result: day-to-day emotional well-being — the mood you’re in right now, rose with income only up to about $75,000 a year, then leveled off. That’s the part that became a headline, a meme, a dinner-party fact.
But the study measured two things. The second was something they called “life evaluation” — how you rate your life overall, the big-picture score. That kept climbing with income. No plateau. The people making $200,000 didn’t feel happier moment to moment than the $75,000 crowd, but they did think their lives were better.
The popular misreading
The pop version grabbed the plateau and dropped the rest. “Money can’t buy happiness past $75k” is a lot easier to remember than day-to-day mood plateaus but life satisfaction keeps rising. I wasn’t trying to be wrong; I wanted permission to stop worrying about my salary.
The 2021 contradiction: Killingsworth’s smartphone study
Killingsworth’s study directly challenged the Kahneman-Deaton plateau, using a new method to capture happiness in real time.
A different method
Matthew Killingsworth, a researcher at Wharton, built a smartphone app that pinged 34,000 volunteers at random moments throughout the day. Over 1.7 million check-ins. Real-time data, not retrospective guesswork.
His finding: happiness doesn’t plateau at $75,000. It keeps rising. No ceiling in sight.
A flat contradiction
Killingsworth found that the richer you are, the happier you feel moment to moment — even above $200,000, based on over 1.7 million experience samples. The $75,000 threshold looked like a methodological artifact, a byproduct of asking people to remember instead of catching them mid-mood.
If you believed the 2010 study, you had a comfortable excuse to stop striving. If you believed the 2021 study, you had to admit that more money might buy more happiness — and maybe you should be earning more, as Killingsworth’s data suggested.
The adversarial collaboration: how they resolved the conflict
To settle the contradiction, Kahneman and Killingsworth joined forces in an adversarial collaboration designed to find the truth rather than win an argument.
What is an adversarial collaboration?
Kahneman and Killingsworth did something rare. They proposed an adversarial collaboration. The two scientists who disagree pool their raw data, bring in a neutral third party, and reanalyze everything together. The third party was Barbara Mellers, a professor at the University of Pennsylvania. No one gets to cherry-pick the results.
What they found when they pooled data
The joint paper, titled “Income and emotional well-being: A conflict resolved,” was published in March 2023 in the Proceedings of the National Academy of Sciences, analyzing 33,391 working US adults with a median household income of $85,000. They looked at 33,391 working US adults with a median household income of $85,000.
The real answer: splitting by baseline happiness
The pooled data revealed that the truth depends on where you start — your baseline happiness level determines how money affects you, with a plateau existing only for the unhappy minority (15-20%).
For 80% of people: happiness keeps rising
For the vast majority — about 80% of people, happiness continues to climb with income past $100,000. No plateau. The $75,000 myth is wrong for most of us. Killingsworth summed it up: “In the simplest terms, this suggests that for most people, larger incomes are associated with greater happiness.”
For the happiest 30% of people, the effect accelerates above $100,000, challenging the idea that there is a cap on the link between money and happiness. More money, more happiness, faster.
For the unhappy 15–20%: a plateau around $100,000
But a minority — about 15 to 20% of people, see a plateau around $100,000, which is the original $75,000 adjusted for inflation. Their happiness rises with income up to roughly $100,000, then flattens. Killingsworth’s blunt take: “The exception is people who are financially well-off but unhappy. For instance, if you’re rich and miserable, more money won’t help.”
This group is the reason the original $75,000 finding wasn’t wrong. It just described a subset of people, not everyone.
The inflation adjustment: $75k then is $100k now
The $100,000 figure isn’t a new magic number. It’s the original $75,000 adjusted for inflation, which is approximately $108,000 in today’s dollars. $75,000 in 2010 is roughly $108,000 today. So the plateau threshold for the unhappy minority has simply moved with the dollar. The median household income in America right now is about $75,000 — meaning the old happiness threshold is now the average.
How much does money really affect happiness?
Even when money boosts happiness, the size of that effect is smaller than many people assume when compared to other life factors.
The modest effect size
A November 2022 study in PNAS Nexus compared the effect of a four-fold income difference to other life factors. The result: that income gap has about the same effect on happiness as being a caregiver, twice the effect of being married, about the same as a weekend, and less than a third of the effect of a headache.
Money is real, but its effect is modest: a four-fold income difference has an effect on happiness roughly equal to being a caregiver, twice the effect of being married, equal to a weekend, and less than a third the effect of a headache.
The diminishing returns of income
The relationship between income and happiness follows a logarithmic curve: two households earning $20,000 and $60,000 exhibit the same difference in well-being as two households earning $60,000 and $180,000. The jump from $20,000 to $60,000 has the same happiness effect as the jump from $60,000 to $180,000. Twice the dollars, same boost. The more you make, the less each additional dollar buys you in well-being.
That said, new research suggests happiness improves up to about $500,000 a year for most people. Above that, data gets thin — participants making over $500,000 are “rare” in the studies. Could keep going, could flatten. We don’t know.
The paradox of chasing money
While money can buy happiness up to a point, the way you pursue it matters — and chasing it can backfire, as a 2003 study in Psychological Science by Kahneman and Diener found.
The 2003 finding: seeking money impairs happiness
In 2003, Kahneman and Ed Diener published a study in Psychological Science that found seeking more money makes you less satisfied with life. People with strong financial success goals reported lower satisfaction with their family life, friendships, and their jobs.
Money as a result vs. a primary goal
Ed Diener put it this way: “It is generally good for your happiness to have money, but wanting money too much is toxic to your happiness much.” Money seems to help when it’s a byproduct of doing good work, not when it’s the main thing you’re aiming at. The difference is between I earn well because I do something valuable and “I will do anything to earn more.”
What this means for you: real-world implications
The $75,000 threshold has been cited in compensation strategy and tax policy discussions, and the new findings from the adversarial collaboration could refine those applications. Dan Price, founder of Gravity Payments, raised minimum salaries to $70,000 in 2015 based on the $75,000 happiness threshold, initially praised as innovative.
The Dan Price case: a real-world test
Dan Price, founder of Gravity Payments, raised his company’s minimum salary to $70,000 in 2015, citing the $75,000 happiness threshold. It was a real-world experiment, though he later stepped down after allegations of a pattern of abusing women. He later stepped down following allegations of a pattern of abusing women.
No universal income threshold
A Gallup poll found that 60% of Americans say they would be happier if they had more money.
The Financial Samurai author went from making $4 an hour at McDonald’s to multiple six figures in investment banking and felt happier once he hit about $200,000 — that was his breathing room number, though his goal is $400,000 in passive income. But his goal is $400,000 in passive income.
The wealthy New Yorkers Rachel Sherman interviewed for her book Uneasy Street said money gave them freedom and control — not stuff, not status, but the ability to say no. Economists Stevenson and Wolfers, in a 2013 study, argued that happiness continued to increase when income went above $500,000, challenging the notion of a fixed threshold.
Practical takeaways
- Try different income levels and rate your own happiness. The only way to know your number is to experience it.
- Spend on experiences, not stuff. Help others. Buy back your time by hiring people for things you hate doing. That’s how money actually helps.
- Don’t make money your primary goal. Focus on the work, the relationships, the purpose. The paycheck can be a byproduct.
- Moving to a lower cost area, living minimally, and practicing gratitude are all valid alternatives to chasing a bigger salary.
The takeaway: a more interesting story than the tidy fact
It applies to a specific unhappy minority (15-20%) after inflation adjustment to $100,000. For the rest of us, more money does buy more happiness — up to about $500,000, with diminishing returns, and only if we don’t obsess over it.
Killingsworth’s honest summary is the best closing line I’ve found: Money is not the secret to happiness, but it can probably help a bit.
I don’t say the $75,000 fact at dinners anymore. The story from the adversarial collaboration is more useful. It tells me that money matters, but it’s not the whole game. That the unhappy minority (15-20%) plateaus around $100,000, but most people (80%) don’t. That chasing money backfires, but earning it through good work doesn’t.
The Beatles had it half right with ‘Money can’t buy me love.’ Money can’t buy you love. But it can buy you more room to breathe, and that’s worth something.
People Also Ask
What’s the difference between emotional well-being and life satisfaction when it comes to income?
Emotional well-being is your moment-to-moment mood—how happy you feel right now—and that’s what showed a plateau at $75,000 in the original study. Life satisfaction is the big-picture rating of how your life is going overall, and that kept rising with income without any ceiling.
How much money do you actually need to be happy?
There’s no universal number. For most people, happiness keeps rising with income up to about $500,000, though with diminishing returns. The unhappy 15–20% see a plateau around $100,000 (the inflation-adjusted $75,000 from 2010). Your personal number depends on your cost of living, baseline happiness, and what gives you breathing room.
How does money’s effect on happiness compare to other life factors?
It’s surprisingly modest. A four-fold income increase has about the same effect as a weekend, roughly twice the effect of being married, and less than a third of the effect of a headache. Other factors like health, relationships, and daily mood states often outweigh income.
