Frequently Asked Questions
What is a Certificate of Deposit (CD)?
A CD is a low-risk savings product offered by banks where you agree to leave a set amount of money untouched for a fixed term (from months to years) in exchange for a guaranteed interest rate.
What are CD early withdrawal penalties?
If you withdraw your money before a CD reaches maturity, the bank charges a penalty, which is usually a set number of months' worth of interest (e.g., 90 or 180 days of interest).
What is a CD ladder strategy?
A CD ladder involves dividing your savings into multiple CDs with staggered maturity dates (e.g., 1-year, 2-year, 3-year). This gives you regular access to cash while capturing higher yields on long-term CDs.
Are CD deposits protected by the federal government?
Yes, CD accounts at FDIC-insured banks (or NCUA-insured credit unions) are backed by the federal government up to $250,000 per depositor, per institution.
What is the difference between CD APY and interest rate?
The interest rate is the simple rate used to calculate interest. The APY (Annual Percentage Yield) represents the actual rate earned in a year, accounting for compounding interest.
