Compounding: the eighth wonder, with numbers

Key idea

Growth on your growth. Slow and dull for years, then it bends sharply upward, and that bend is where the wealth is.

Compounding means your returns start earning returns of their own. Year one, you earn on your money. Year two, you earn on your money plus last year's gains. The gains stack, and the stack grows the stack.

The line barely lifts for years. This is where most people give up, convinced it isn't working. Then it curves upward, because by then the growth is generating serious growth of its own. The last few years add more than the first ten combined.

The two ingredients

  • Time

    the big one

  • Consistency

    every month

  • Rate

    matters least

The counter-intuitive part: time matters more than the amount or the rate. The bend only appears if you leave money in place long enough to reach it. Interrupt it, and you reset the curve to flat. Compounding rewards the patient far more than the clever.
