What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. It's often called "interest on interest" and can significantly boost your investment returns over time.

The basic compound interest formula is: A = P(1 + r/n)^(nt)

  • A = Final amount
  • P = Principal (initial investment)

  • n = Number of times interest compounds per year
  • t = Time in years
