How Compound Interest Works

Compound Interest is interest calculated on both the principal and the accumulated interest from previous periods. This creates an exponential growth effect over time.

Formula: A = P(1 + r/(n×100))^(n×t)

  • A = Final amount
  • P = Principal (initial amount)
  • r = Annual interest rate (%)
  • n = Number of times compounded per year
  • t = Time in years

💡 Pro Tip: More frequent compounding (daily vs annually) results in higher returns. The monthly breakdown table helps you visualize exactly how much you earn each month, making it easier to understand the power of compound interest.
