There is an optimal point to how much money it takes to make an individual happy, and that amount varies worldwide, according to research from Purdue University.
“That might be surprising as what we see on TV and what advertisers tell us we need would indicate that there is no ceiling when it comes to how much money is needed for happiness, but we now see there are some thresholds,” said Andrew T. Jebb, the lead author and doctoral student in the Department of Psychological Sciences. “It’s been debated at what point does money no longer change your level of well-being. We found that the ideal income point is $95,000 for life evaluation and $60,000 to $75,000 for emotional well-being. Again, this amount is for individuals and would likely be higher for families.”
