“Once your income hits $75,000, have you hit the peak salary for happiness?

Not quite.

The oft-cited $75,000 figure—now about $110,000 in today’s dollars—comes from a 2010 study by two Nobel laureates that made the crossover from academia to personal-finance meme. More recent research suggests that there may be no household income at which happiness peaks, and that our money might influence our emotions well beyond that threshold…

Much of the current thinking on this debate can’t be summed up in a single number, but rather 10 words: Money buys happiness. With diminishing returns. And no magic number.”
