Happiness is yours – for $75,000 a year

Researchers are always studying personal satisfaction. Last week, we looked at how money — spent on others — can contribute to personal happiness.

Today, we're looking at research that studied income levels and happiness. Can money buy us happiness? Apparently yes. And the magic number is $75,000.

Nobel prize-winning psychologist Daniel Kahneman and economist Angus Deaton examined data from the Gallup-Healthways Well-Being Index and found that household happiness increased as household income increased — up until that income hit $75,000. Beyond $75,000, "emotional well-being flat-lined," Newser reported on the findings.
