Over at personal finance blog Hello, Dollar! they’ve got a great post about how bringing your four times a week can eventually earn you half a million dollars.
So let’s see, four days bringing lunch at $2 plus one day out at $7 equals $15 per week. Eating out every day would cost $35 per week, so I save $20. $20 a week! That’s over $80 a month — that covers my utility bills right there. Who couldn’t use that?
40 years and the miracle of compound interest turns that into $581,826! Nice!
