How Compound Interest Works

1

Principal Growth

Your initial investment earns interest, which is added to your principal.

2

Compounding Effect

Interest starts earning interest, creating exponential growth over time.

3

Regular Contributions

Monthly investments significantly accelerate your wealth building.

Key factors that affect compound growth:

  • Interest Rate: Higher rates dramatically increase your final amount over long periods
  • Time: The longer you invest, the more powerful compounding becomes
  • Contribution Frequency: More frequent compounding (daily vs monthly) yields slightly better returns
  • Regular Investments: Consistent monthly contributions can outperform lump-sum investments
