Study: This is how much money you need to earn to be financially successful

A study by the financial services company Empower found that this is the annual income that indicates financial success. But respondents also said success was about more than just wealth.

For years, researchers have tried to pinpoint the amount of money Americans need to earn in order to feel happy. One oft-cited study from 2010 put that number at just $75,000, but subsequent research has found that happiness can actually keep increasing until your income crosses $100,000.
