## What is the Rule of 69?

The Rule of 69 is a simple yet powerful tool used to estimate the amount of time it will take for an investment to double, assuming continuously compounded interest. This calculation is based on the idea that the number 69 is a mathematical constant that can be used to predict the growth rate of an investment.
