A CD locks your money away for a set time in exchange for a fixed rate. Whether that’s worth it depends on when you’ll need the cash.
Key takeaways
- A certificate of deposit (CD) pays a fixed rate for a set term, such as several months or years.
- Withdrawing before the term ends usually means an early withdrawal penalty.
- Savings accounts offer flexibility but usually have variable rates.
- CDs can suit money for a known future date; savings accounts suit emergencies and flexible goals.
When you’re saving for something specific, you have a choice: keep the money flexible in a savings account, or lock it into a certificate of deposit for a fixed rate. Each fits different goals, and many savers use both.
How they compare
| Factor | Certificate of deposit | Savings account |
|---|---|---|
| Interest rate | Fixed for the term | Usually variable |
| Access | Locked until maturity | Withdraw when you need to |
| Early withdrawal | A penalty usually applies | Typically no penalty |
| Best for | Money for a known future date | Emergencies and flexible goals |
| Deposit insurance | Yes, at insured institutions | Yes, at insured institutions |
When a CD makes sense
- You know when you’ll need the money, such as a planned purchase in a year or two.
- You want a rate that won’t change during the term.
- You’re confident you won’t need the money early.
When a savings account is better
- For your emergency fund, where quick access matters most.
- When you’re not sure when you’ll need the money.
- When you’re still building savings with regular deposits, since most CDs take a single opening deposit.
Be aware
Early withdrawal penalties can eat into, or even exceed, the interest you’ve earned. Read how the penalty is calculated before you open a CD.
A middle path: CD ladders
- Split your money across several CDs that mature at different times.
- As each one matures, use the money or reinvest it.
- Part of your savings becomes available at regular intervals, while the rest keeps earning fixed rates.
Money tip
Put each CD’s maturity date in your calendar. Many CDs renew automatically after a short grace period, sometimes at a different rate.
Types of CDs you may see
- Traditional CDs with a fixed rate and a penalty for early withdrawal.
- No-penalty CDs, which let you withdraw early without a penalty, usually in exchange for a lower rate.
- Bump-up CDs, which may let you request a higher rate once if rates rise during the term.
- Brokered CDs, bought through a brokerage account, which work differently and can lose value if sold before maturity.
Questions to ask before opening a CD
- What’s the term, and what’s the rate for that term?
- How is the early withdrawal penalty calculated?
- What happens at maturity, and how long is the grace period?
- Is the institution FDIC- or NCUA-insured?
The bottom line
Use a savings account for flexibility and emergencies, and consider a CD for money you won’t need until a known date. Compare rates and terms, and always check the penalty. For flexible options, see our comparison of high-yield and regular savings accounts, and for planned costs, sinking funds.
