The $75,000 number everyone gets wrong
You've probably heard this one at a dinner party: money stops making you happier once you cross $75,000 a year. It gets dropped like established fact, usually by someone who read it in a listicle once and never checked further.
Here's the problem. It's only half right, and the half that's missing is the important one.
The number traces back to a real study, published in 2010 by Daniel Kahneman and Angus Deaton in the journal PNAS. Then in 2021, a researcher named Matthew Killingsworth ran a much larger study and got a result that seemed to flatly contradict it. In 2023, the two of them actually joined forces to figure out what was really going on.
Turns out they were both right, just about different things. Here's what the data actually says, and what to do with it.
What Kahneman and Deaton actually measured
Kahneman and Deaton pulled Gallup survey data from 450,000 Americans. The key move: they separated two things people usually lump together under "happiness."
Emotional wellbeing: how you actually felt yesterday. The joy, the stress, the small frustrations. Your lived, in-the-moment experience.
Life evaluation: how you'd rate your life overall if you stepped back and graded it. The big-picture verdict.
Here's what they found. Life evaluation kept climbing as income rose, with no ceiling anywhere in the range they studied. Emotional wellbeing also climbed with income, but it flattened out around $75,000 (in 2008 dollars).
That's the whole finding. But somewhere between the paper and the dinner-party retelling, it got compressed into "happiness plateaus at $75K," as if the two measures were the same thing. They're not. One kept rising without limit. Only the other one stalled.
The 2021 study that seemed to blow it up
Matthew Killingsworth, a researcher at the University of Pennsylvania, took a different approach entirely. Instead of asking people to recall their week on a survey, he built an app that pinged 33,000 people at random moments throughout the day and asked how they felt right then.
The result: emotional wellbeing kept rising with income, no plateau in sight, all the way up to at least $500,000.
Headlines ran with "Kahneman was wrong, money does keep buying happiness." That framing wasn't quite right either, but it set up a genuinely interesting puzzle: two careful studies, two very different answers.
The 2023 paper that settled the argument
Instead of arguing past each other in journals, Killingsworth and Kahneman did something academia doesn't do nearly often enough. They brought in a third researcher as a neutral referee and ran the numbers together to find out exactly where the disagreement lived.
The answer split the population in two.
For roughly 80% of people, emotional wellbeing keeps rising with income right through the top of the range studied. No plateau, no ceiling.
For the unhappiest 20% or so, wellbeing rises with income up to about $100,000, and then flattens out completely. More money stops registering.
Who ends up in that unhappy 20%? Mostly people dealing with something money doesn't touch directly: a struggling relationship, a health crisis, grief, depression. For them, a bigger paycheck doesn't fix the actual problem, so it stops showing up as relief.
For everyone else, the money keeps helping, well past the point the original "plateau" story said it should stop.
What this actually means for you
Three things fall out of this.
If your day-to-day life is basically going fine, more income will probably keep improving how your days feel. There's no secret ceiling waiting for you at $75,000.
If your life feels like it's falling apart and the cause isn't financial, a raise won't fix it. This is the one place where the old "plateau" story holds up completely: the money was never the actual constraint.
And yes, diminishing returns are real, just further out than the popular version claims. You do get used to more money. But each new increment still buys something, just a little less than the last one did.
Why the treadmill keeps moving
This is the mechanism behind what researchers call the hedonic treadmill (we've written about the Stoic take on this too): whatever your life looks like right now becomes the new normal within about a year, often faster. Win the lottery, and you land back near your old baseline mood within roughly 18 months. Survive a serious accident, and something similar happens in reverse: people adapt back toward baseline faster than they'd ever guess beforehand.
That's why a raise never feels like it should. Your brain absorbs the new baseline quickly, then starts measuring everything against that, not against where you started.
But the treadmill doesn't mean money stops mattering. It flattens the curve; it doesn't zero it out. Every raise still buys something real: better food, a safer place to live, more time with people you love because you're not working three jobs, a trip you couldn't have swung before. Those things keep paying off long after the initial thrill fades.
What doesn't keep paying off, no matter how much you throw at it, is the stuff money was never built to buy directly: close relationships, a sense of meaning, health past a certain point. Those plateau fast, regardless of your bank balance.
So what do you actually do with this
Three moves, roughly in order.
First, get your income to the point where it solves your money-shaped problems. Housing. Healthcare. Reliable food. Enough of a cushion that a surprise bill doesn't wreck your month. These are real constraints, and money genuinely fixes them.
Second, be honest about what your actual bottleneck is. A lot of people assume money is the problem when the real issue is time, connection, or a job that's slowly grinding them down. Chasing a bigger number while ignoring the real constraint just buys you a richer version of stuck.
Third, once the money-shaped problems are handled, put your energy into the things that don't max out: connection, getting better at something you care about, and meaning that isn't tied to your bank balance. That's where the durable gains come from, once money stops being the thing holding you back.
Where TaskCoach fits
TaskCoach.AI tracks your income and savings inside the Wealth pillar, but it's deliberately just one pillar out of seven. The design leans against the cultural habit of treating money as the only lever worth pulling, at the expense of Body, Social, and Mind. The Killingsworth-Kahneman data backs that choice up: past a certain point, pouring more into Wealth alone produces smaller and smaller returns, while the pillars you're neglecting quietly rack up losses that compound the other way.
The bottom line
The "$75K plateau" story, as most people have heard it, is mostly wrong. For most people, money keeps improving daily life well past that number. The plateau is real, but it only applies to people whose problems were never about money to begin with.
Get your income to the point where it solves what it can actually solve. Then put your attention on the things that don't have a ceiling. Both halves of this research turned out to be true. Together, they're a lot more useful than either one alone.
