How Compound Interest Works

Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. The formula used is: A = P(1 + r/n)nt, where:

  • A = the future value of the investment
  • P = the principal investment amount
  • r = the annual interest rate (decimal)
  • n = the number of times interest is compounded per year
  • t = the number of years the money is invested
