What is a Certificate of Deposit (CD)?

A certificate of deposit is a type of savings account that holds a fixed amount of money for a fixed period of time, such as 6 months, 1 year, or 5 years, and in exchange, the issuing bank pays interest.

How does a CD calculator work?

A CD calculator helps determine how much interest you'll earn on your certificate of deposit. Enter your initial deposit, interest rate, term length, and compounding frequency to calculate your returns.

Are CDs safe investments?

Yes, CDs are considered very safe because they are typically insured by the FDIC up to $250,000 per depositor, per bank.

What happens if I withdraw my money early from a CD?

Withdrawing money before the CD matures usually results in an early withdrawal penalty, which can reduce your earned interest or even your principal.

Can I add more money to my CD after opening it?

Most CDs do not allow additional deposits after the initial opening. You would need to open a new CD for additional funds.
