A certificate of deposit — CD — is a savings tool where you agree to leave money at a bank for a fixed period in exchange for a guaranteed interest rate. The bank knows how long it has your money, so it can offer a better rate than a regular savings account. You know exactly what you’ll earn. The tradeoff is flexibility: early withdrawal usually costs a penalty.
How CDs work
When you open a CD, you deposit a set amount and choose a term — typically anywhere from 3 months to 5 years. The bank pays a fixed interest rate for that entire period, and at the end (called maturity), you get your original deposit back plus the interest earned.
CD rates are fixed at the time you open the account. That’s an advantage when rates are high and falling — you lock in today’s rate for the full term. It’s a disadvantage if rates rise after you’ve committed.
Early withdrawal penalties
If you need your money before the CD matures, most banks charge a penalty — typically a certain number of months of interest, ranging from 60 days for short-term CDs to a year or more for long-term ones. The penalty can sometimes eat into your principal if you withdraw very early.
Some banks offer no-penalty CDs that allow early withdrawal without a fee (usually after a short initial window). The tradeoff is typically a slightly lower rate.
CD laddering
CD laddering is a strategy for keeping some of your savings accessible while still earning better rates. Instead of putting all your money into one 5-year CD, you divide it across multiple CDs with different maturity dates — say, 1, 2, 3, 4, and 5 years. As each CD matures, you decide whether to spend the money, keep it accessible, or roll it into a new CD.
Laddering reduces the risk of having all your money locked up when you need it, and reduces the risk of locking in a bad rate for the full term.
When CDs make sense
- You have money you’re confident you won’t need for the term period
- You want a guaranteed, predictable return with no market risk
- Current CD rates are attractive and you want to lock them in
- You’re building a short-term savings cushion for a specific goal (a purchase, a trip, a large expense)
When CDs may not be the right fit
- You might need the money before the CD matures
- You want higher long-term returns — CDs are savings tools, not investments
- Interest rates are rising, making it risky to lock in today’s rate for a long term
Safety
CDs at FDIC-insured banks are covered up to $250,000 per depositor, per bank — the same protection as a savings or checking account. CDs at credit unions are covered by the NCUA at the same limit.
