Understanding Certificate of Deposit (CD) Rates

A Certificate of Deposit (CD) is a type of savings account that holds a fixed amount of money for a fixed period of time, typically with a fixed interest rate. When you deposit money into a CD, you are essentially lending that money to the financial institution. In return, the institution pays you interest on your deposit.

The CD rate, often expressed as an Annual Percentage Yield (APY), is the effective rate of return on your investment, taking into account the effect of compounding interest. A higher CD rate means you will earn more interest on your deposit over the term of the CD.

How to Calculate Your Potential CD Earnings

The following calculator will help you estimate the earnings on your Certificate of Deposit based on the principal amount you deposit, the annual interest rate, and the term of the CD in years. This calculation uses simple interest for each compounding period and then sums them up. For more precise calculations considering frequent compounding, a financial professional or a more complex formula would be required, but this provides a good estimate.
