If Americans put their spare bedrooms to use as rentals—rather than junk rooms, man caves or craft stations—they could pocket as much as $6.2 billion a week.
A new analysis from Finder.com found there are over 9.4 percent more bedrooms in the U.S. than people -- 357 million bedrooms but only 323.4 million people. That leaves at least 33.6 million spare rooms. And there are likely even more extra bedrooms since many couples share a room, the analysis concluded.
Americans in bigger cities could get significantly more than the national average. For example, Phoenix residents can get $338 a week ($17,576 a year), while people in Nashville, Tenn., can rake in $572 a room per week to the tune of nearly $30,000 a year.
