The Math Behind Wealth
Compound interest is the cycle of earning interest on your interest. It causes wealth to grow exponentially rather than linearly. The key factor is time: the earlier you start, the less you need to contribute monthly to reach a million dollars.
A = P(1 + r/n)^(nt)
A = Future Value • P = Principal • r = Rate • t = Time
