RULE OF 72

Story telling time~~~~~~~~~~~~

Ah Lan save RM100k in an investment yielding 10% annually. All the annual interest will be reinvested. How long does it take to double his money to RM200k?

Using the rule of 72:
72 divide by 10 (the interest rate)= 7.2 years for the money to double to RM200k.

How about 2% annually like bank account interest yield. Lets do the math:
72 divide by 2= 36 years!!! Bloody hell!!!

Now u understand why financially smart people don't tuck most of their money in bank accounts... Losers!
