Pro Tip

The "Rule of 72" helps you estimate how long it takes to double your money: 72 divided by the annual return rate.

Compound growth is the process by which the value of an investment grows exponentially because the earnings from the investment are themselves earning interest.

The Power of Time

In the early years, growth seems slow. However, as the principal base grows, the earnings become larger, which then earn even more. This creates an accelerating growth curve where the majority of wealth is generated in the final years.

Reinvestment is Key

For dividend investors, compound growth is driven primarily by reinvestment. By using dividends to buy more shares (DRIP), you increase your share count. Those new shares then pay their own dividends, which buy even more shares.

Inflation Hedge

Compounding is the best defense against inflation. If your portfolio grows at 8% and inflation is 2%, your purchasing power is still compounding at a net 6% rate, ensuring your future lifestyle is protected.
