How much wealth does it take to find happiness? Some people claim that the finest things in life are priceless, while others feel most fulfilled when securing multimillion-dollar contracts from the comfort of their private car.
There’s no definitive answer to this question; naturally, the amount of money required for happiness depends on you, your situation, and your surroundings. (And of course, delving into what exactly happiness means could trigger a whole other realm of existential uncertainty.) It's unlikely you'll be content if you can't afford life's essentials—such as food, clean water, shelter, and healthcare—but does that mean all millionaires are happier than the rest of us? Certainly not. Money alone doesn't guarantee happiness.
Thus, answering this question is no simple feat, though economists haven't been deterred from attempting to crack the code. Previous studies have suggested that the “ideal salary for happiness” in the U.S. hovers around $75,000 annually. Research indicates that earning more up to this point improves happiness, but after that threshold, daily happiness levels stabilize (although researchers clarified that this doesn’t mean more money doesn’t enhance life satisfaction).
New findings from Purdue University add complexity to and refine this notion. Published in Nature Human Behaviour, the study proposes that optimal income levels vary by individual for two distinct measures: “life evaluation” (a person’s overall assessment of their life, influenced by higher aspirations and comparisons to others) and “emotional well-being” (day-to-day emotions like happiness, excitement, sadness, and anger), both of which differ across the globe.
The study found that the optimal income for an individual worldwide is $95,000 for life evaluation and between $60,000 and $75,000 for emotional well-being. Beyond these amounts, further increases in income may actually be linked to a decline in life satisfaction and well-being. The authors clarify that these figures are estimates applicable only to individuals living alone, meaning they are likely much higher for those in family households.
The research draws on data from the Gallup World Poll, which has surveyed over 1.7 million people across 164 countries. Naturally, the findings vary by region, with higher incomes proving more significant in wealthier areas like Western Europe and North America.
The study's authors note in Nature Human Behaviour that these estimates likely fluctuate even within a single country, particularly in places with vastly different living costs, like the U.S.
So, what should we take away from this? Well, while it’s true that a certain level of income is necessary for happiness, the pursuit of happiness involves more than just money—where you live matters, and your emotional well-being is distinct from your overall life satisfaction.
Most importantly, spending money on material goods or upgrading your home won't lead to greater happiness. As Andrew Jebb, the study's lead author, shared with Mic, if you’re seeking happiness, you should focus less on yourself: “People tend to be better off when they spend their money... in service of other people,” he said.
