The average personal amount of savings are between $ 2,900 for the USA and ¥ 5,806,554 for Japan. The USA comes last in our ranking, but their neighbor Canada is one of the richest countries regarding personal savings.
I don't know how they've made those calculations as I've heard from a credible source that 75% of USA residents don't have $500 until the next month's paycheck. So you could say that they're living paycheck to paycheck.
