The Rule of 114 tells an investor how long it will take for their money to triple in value.  Here’s an example using a $5,000 investment.

Rule of 114:  Take the number 114 and divide it by the interest rate you hope to receive on your investments.  You have $5,000 invested at 9%, so it will take 12 years and 7 months for your money to triple, earning $15,000.  (114 divided by 9 = 12.666).
