I am 20. If I started putting in the maximum amount (I think it is $100 a week now) this week, and did this until 59.5, how much interest would I really gain. I know this is hard to calculate with inflation and all, but would my money double? triple? I am just starting to look into it and am curious how much money I would really make. Roughly how much money would I get when I turn 59.5(total), if I put in the maximum amount, every week?
