Interest Calculator

Use this calculator to find out how much interest you can earn on a deposit account. Just enter a few pieces of information and we will calculate your APY and ending balance.

Initial deposit:
The starting balance for your CD.

Months:
The total number of months for this CD to mature. A Month is equal to a year divided by 12 or 30.416 days. A year is equal to 365 days.

Interest rate:
The published interest rate for this CD. Make sure to enter the actual interest rate, not the Annual Percentage Yield (APY).

Annual Percentage Yield (APY):
This is the effective annual interest rate earned for this CD. A CD's APY depends on the frequency of compounding and the interest rate. Since APY measures your actual interest earned per year, you can use it to compare CD's of different interest rates and compounding frequencies.

Compounding:
Interest earned on your CD's accumulated interest. This calculator allows you to indicate the frequency with which your CD's interest income is added to your account. The more frequently this occurs, the sooner your accumulated interest income will generate additional interest. The interest will remain and compound with principal.
