What is a CD (Certificate of Deposit)?

A CD is a savings account that holds a fixed amount of money for a fixed period (term) at a guaranteed interest rate. Unlike regular savings accounts, you can't withdraw money before maturity without paying an early withdrawal penalty. CDs are FDIC-insured up to $250,000, making them very safe investments.

What happens when a CD matures?

When your CD reaches its maturity date, you have several options: 1) Withdraw your principal plus interest, 2) Roll it over into a new CD (often automatic), or 3) Add more money and open a new CD. Most banks give you a 7-10 day grace period to decide without penalty.

What is the early withdrawal penalty for CDs?

Early withdrawal penalties vary by bank and CD term. Common penalties are 3-6 months of interest for CDs under 2 years, and 6-12 months of interest for longer terms. Some banks charge a percentage of principal. Always check your CD agreement before withdrawing early.

Are CD rates better than savings account rates?

Generally yes. CDs typically offer higher rates than savings accounts (often 1-2% more) because you commit to leaving your money untouched for a set period. Longer CD terms usually offer higher rates. However, high-yield savings accounts sometimes match short-term CD rates with more flexibility.
