Amount:
The formula for Compound Interest: F=P(1+r/n)nt
  • P =initial principal

  • r = annual nominal interest rate

  • n = number of times the interest is compounded per year

  • t = number of years

  • F = future amount after time t

Example usage: If you start a bank account with $1200 and your bank compounds the interest quarterly at an interest rate of 4.2%. Find the balance after 5 years.Using the formula above, with P = 1200, r = 4.2/100 = 0.042, n = 4, and t = 5:F=1200X(1+0.042/4)4X5 .So, the balance after 5 years is $1478.79.
