La regla del 72 es un método simple para determinar cuánto tiempo le tomará a una inversión duplicar su valor, dada una tasa de interés anual fija (compuesta).
Por ejemplo:
A una tasa de 6%, el dinero se duplicará en 12 años (72/6 = 12)

The 'Rule of 72' is a simplified way to determine how long an investment will take to double, given a fixed annual rate of interest. By dividing 72 by the annual rate of return, investors can get a rough estimate of how many years it will take for the initial investment to duplicate itself.
For example, the rule of 72 states that $1 invested at 10% would take 7.2 years ((72/10) = 7.2) to turn into $2. In reality, a 10% investment will take 7.3 years to double ((1.10^7.3 = 2).
When dealing with low rates of return, the Rule of 72 is fairly accurate.
