Divide 72 by your annual interest rate to approximate how many years it will take to double your investment (e.g. at 8%, 72 / 8 = 9 years).
Why does more frequent compounding yield more money?
More frequent compounding credits interest earlier, meaning subsequent interest calculations operate on a larger base.
