We often come across schemes that promise to double our money in a certain number of years. Sitting at the comfort of your home, even you can calculate by when your money will double if you are aware of the Rule of 72! For example, at 9% p.a., it should take 72/9 = 8 years (approximately) to double the money. The number at which you will arrive is the number of years in which your money will double. Similar to Rule of 72, the Rule of 114 and the Rule of 144 tell you when your money will triple and grow four times respectively.
