Question: how long does it take to quadruple your money?
Answer: Rule of 114 can be used to determine how long it will take an investment to triple, and the Rule of 144 will tell you how long it will take an investment to quadruple. For example, at 10% an investment will triple in about 11 years (114 / 10) and quadruple in about 14.5 years (144 /10).
