If I invest $600 at an 11.5% interest rate, how much money will I earn over 5 years?

If you had $600 in an account with a 11.5% interest rate and 5 years of time you would have $1,034.01 at the end of 5 years and would have earned $434.01 in compound interest. If you accounted for inflation you would actually have $891.95 in today's currency (buying power, not actual numbers)
