A certificate of deposit, or CD, is a savings product that pays a fixed interest rate if you leave your money untouched for a set period. It is one of the safest ways to earn a predictable return, which is why CDs are popular with retirees, conservative savers and anyone saving for a goal with a specific date. This guide explains how CDs work, what they cost and when they make sense compared with other savings options.
How a CD Works
When you open a CD, you deposit a lump sum for a fixed term, such as three months, one year or five years. In exchange, the bank or credit union pays a fixed rate for that term. At maturity, you receive your principal plus interest. If you withdraw before maturity, you typically pay an early withdrawal penalty, usually several months of interest.
CDs are insured by the FDIC at banks and by the NCUA at credit unions, up to $250,000 per depositor, per institution, per ownership category. You can check coverage details at fdic.gov.
Typical CD Terms
CD terms commonly range from three months to five years. Some institutions offer even longer terms. Rates depend on market conditions and the length of the term. Sometimes longer terms pay more, but when short-term rates are higher than long-term rates, the opposite can be true. Compare current offers before choosing.
Types of CDs
- Traditional CD. Fixed rate and term, with early withdrawal penalty.
- No-penalty CD. Allows withdrawal without penalty after an initial waiting period, usually with a slightly lower rate.
- Bump-up CD. Lets you raise your rate once or twice during the term if rates rise.
- Jumbo CD. Requires a larger deposit, such as $100,000, and may pay a higher rate.
- Brokered CD. Bought through a brokerage, often with a wider selection and the ability to sell on a secondary market, though the price may vary.
- IRA CD. A CD held inside an individual retirement account.
CD vs. High-Yield Savings
| Feature | CD | High-yield savings |
|---|---|---|
| Rate | Fixed for the term | Variable |
| Access | Locked until maturity | Flexible |
| Penalty for early withdrawal | Yes | Generally none |
| Best for | Known timelines, locking in a rate | Emergency funds, flexibility |
| Rate risk | Protects if rates fall, misses out if rates rise | Benefits when rates rise, falls when they drop |
For help choosing a savings account, read our HYSA guide. Many savers use both: a high-yield account for emergencies and CDs for money they will not need for a while.
Pros of CDs
- Safety. FDIC or NCUA insurance protects your deposit within limits.
- Predictable returns. You know exactly what you will earn.
- Higher rates than traditional savings, often competitive with HYSAs.
- Discipline. The penalty discourages impulse spending.
- Simple. No market fluctuations.
Cons of CDs
- Limited liquidity. You cannot easily access the money.
- Early withdrawal penalties can eat into interest, and sometimes principal.
- Opportunity cost if rates rise after you lock in.
- Inflation risk. A fixed rate may not keep up with rising prices.
- Renewal traps. Many CDs automatically renew at the current rate if you do not act.
What Early Withdrawal Penalties Look Like
Penalties vary by bank and term. A typical penalty might be 90 days of interest on a one-year CD or 180 to 365 days of interest on longer terms. If you withdraw very early, the penalty could exceed the interest earned and reduce your principal. Always read the terms before opening.
Building a CD Ladder
A CD ladder spreads your money across CDs with different maturities so you have regular access to cash and can take advantage of changing rates. For example, with $10,000 you might buy five CDs of $2,000 each with terms of one, two, three, four and five years. Each year, one CD matures. You can use the money or reinvest it in a new five-year CD, keeping the ladder going. This approach balances higher long-term rates with periodic liquidity.
Taxes on CD Interest
CD interest is taxed as ordinary income in the year it is earned, even if you do not receive it until maturity for longer CDs. You will receive a 1099-INT if you earn $10 or more. Holding CDs inside an IRA can defer or eliminate this tax. Learn more about retirement accounts in 401(k) vs. Roth IRA.
How to Choose a CD
- Define your goal and timeline. Match the CD term to when you need the money.
- Compare APYs from online banks, credit unions and traditional banks.
- Check penalties and withdrawal rules.
- Confirm insurance coverage.
- Look at minimum deposits.
- Understand renewal policies and set a reminder before maturity.
- Consider the rate environment. If rates are high and expected to fall, longer terms can lock in a good return.
When a CD Makes Sense
- Saving for a specific date, such as a house down payment in two years.
- Retirees seeking predictable income.
- Conservative investors who want no market risk.
- Savers who tend to spend and want a commitment device.
- Part of an emergency fund, for the portion you would use last.
If you are focused on growth over many years, investments such as index funds may fit better. See index funds vs. ETFs and starting to invest with little money.
Common Mistakes
- Locking in money you may need.
- Letting a CD auto-renew at a poor rate.
- Exceeding insurance limits.
- Ignoring inflation.
- Not comparing rates across institutions.
- Overlooking early withdrawal terms.
What to Do Before a CD Matures
About a month before maturity, your bank will usually send a notice. Compare renewal rates with the best market offers, because renewal rates are often lower than new-customer rates elsewhere. Decide whether you will withdraw the cash, roll into a new CD or move to a high-yield savings account. Mark the grace-period deadline on your calendar so the CD does not renew automatically into a term you do not want.
Frequently Asked Questions
Are CDs a good investment?
They are a safe savings tool rather than a growth investment. They suit short- to medium-term goals.
Can I lose money in a CD?
Not if the CD is insured and within limits. You can lose interest, and potentially principal, if you withdraw early.
What happens at maturity?
You typically have a grace period of about 7 to 10 days to withdraw, roll over or change terms.
Can I add money to a CD?
Usually not, except with add-on CDs.
Bottom Line
CDs offer safe, predictable returns for money you can lock away. Compare rates, understand penalties, consider a ladder and use CDs alongside a high-yield savings account.
