How long will it take to triple your money at 4.6 percent?
There is what's called the "rule of 72" which states, you divide
the percent into 72 and that tells you how log it takes to double
your money. For example, 4.6 goes into 72 15.65 times. So, it would
take 15.65 years to double your money. That's not too good of an
investment.
72 ÷ 4.6 = 15.65
