Rule72Calc のアプリ分析 3月14日

The Rule of 72 is a simple financial tool used to estimate the time it takes for an investment to double, based on a fixed annual rate of return. The basic idea is to divide 72 by the annual rate of return (expressed as a percentage). Rule72Calc provides a more precise method for calculating the doubling time and increase rate, based on natural logarithms and exponential functions. This approach adheres to the basic principle of the Rule of 72 while offering more accurate results through mathematical formulas.
