The Rule of 72: Why Time Matters More Than You Think
The Rule of 72 is one of the simplest ways to understand the relationship between time and compounding. In this episode, I explain how to estimate the time money may take to double at an assumed annual return, why starting earlier can matter so much, how superannuation benefits from a long time horizon, and how high-interest debt can compound in the opposite direction. The Rule of 72 is an approximation, not a prediction. Returns are not guaranteed and real outcomes depend on fees, tax, inflation, market movements and individual circumstances.
