The EKO24 Compound Interest Calculator helps estimate how an initial deposit and regular monthly contributions may grow over time when interest is added to the balance.

How compound interest works

Compound interest means that interest can be earned not only on the original amount but also on interest previously added to the balance. Over longer periods, this can significantly affect the final value.

  2. Add the amount you plan to contribute each month.
  3. Enter the expected annual interest rate.
