What is Compound Interest?

Compound interest is interest that accrues not only on the initial capital but also on the accumulated interest from previous periods. It's the famous "interest on interest" that makes your money grow exponentially.

Formula: A = P × (1 + r/n)^(nt)

  • A: Final amount
  • P: Principal (initial capital)
  • r: Annual interest rate (as decimal)
  • n: Number of compounding periods per year
  • t: Time in years

Why is Compound Interest Important?

Compound interest is the foundation of long-term investment growth. The longer your investment period, the more significant the effect of compound interest.

  • Exponential Growth: Your money grows faster over time
