The Power of Compounding & Rule of 72
Compound interest generates geometric wealth expansion by applying future returns not only to initial capital but also to previously accumulated reinvested earnings.
Under the Rule of 72, an investment growing at 8% doubles every 9 years ($72 / 8 = 9$). Over decades, patient recurring investments dramatically outstrip simple linear savings.
