Compound Interest Calculator
A Compound Interest Calculator For Savers

The compound interest calculator is intended to show you how how much you'll have saved after a given number of years. You'll know how much of your final balance is due to interest earnings, and you can use the compound interest calculator to see how different interest rates affect the outcome.

Instructions for using the compound interest calculator:

  • Put your original deposit amount into the box for "Principal"
  • Enter your APY in the "Rate" box
  • Finally, enter a time period into the "Years" box

Note that the compound interest calculator allows you to enter your time period in months or years.  If you'd like to use months, use the table at the right of the compound interest calculator.  For example, if you want to calculate based on 7 months, enter ".58" in the "Years" box.

The compound interest calculator shows how much a single deposit will be worth in the future.  You can use it to compare accounts and determine whether it is worth your efforts to switch for a better rate.
