Retirement CDs: A complete guide to using certificates of deposit for retirement planning
You can spend decades planning for retirement, but the nature of the planning changes as you approach your retirement date. Instead of investing entirely for a far-off future, as retirement approaches, you need to make sure your money will be available when you start to need it. That’s where retirement CDs can come in handy.
Whether it’s required minimum distributions (RMDs) or everyday living expenses, reaching retirement means planning when you’ll need to draw on your savings. Retirement CDs are a popular option because they allow you to keep money invested productively until the precise time when you’ll need it.
This article explains how CDs work and what role they can play within retirement plans like IRAs and 401(k) plans. This background can help you decide whether IRA or 401(k) CDs are a good fit for your needs.
What are certificates of deposit (CDs) and how do they work?
CDs are time deposits, also known as term deposits. These are financial products that last for a specified length of time. That length of time is known as the CD’s term. CD terms can range from a month to several years. The date when the CD term expires is called the maturity date.
CDs often pay higher interest rates than deposits in savings or money market accounts. In exchange for this higher interest rate, you must agree to keep your money in the CD until its maturity date. If you withdraw your money before the maturity date, you’ll typically pay an early withdrawal penalty.
Most CDs have fixed interest rates, which means they will pay the same rate throughout their term. This is useful for retirement planning purposes because it allows you to know in advance exactly how much money you’ll have when the CD matures.
CDs that are issued by banks are protected by Federal Deposit Insurance Corp. (FDIC) insurance. Those issued by credit unions are protected by a similar type of insurance through the National Credit Union Administration (NCUA). This insurance makes eligible CDs among the safest investment options available, within applicable coverage limits.
One downside to CDs is that they don’t have the growth potential of stocks and other more aggressive investments. CDs are appropriate when you favor preservation of capital over long-term growth. This is often a good fit for at least a portion of your retirement savings as you approach the time you’ll begin drawing on those assets.
Using certificates of deposit in retirement accounts: IRA CDs and 401(k) CDs
IRA CDs are no different from any other CD, except they’re held with a traditional or Roth IRA account. Just as you may hold stocks, bonds, and other investments in your IRA, CDs are another option you can add to the mix.
How CDs work within retirement accounts
CDs and retirement accounts serve different purposes. CDs provide a fixed interest rate for a specified period. Retirement accounts provide tax advantages for eligible investments held within the account, which may include CDs.
When you use a CD within an IRA, you combine the safety and fixed return of a CD with the tax advantages of an IRA. In theory, you could also have a CD within a 401(k), but 401(k) CDs are less common than IRA CDs. That’s because the CD would have to be on the menu of options offered by the 401(k) plan, and to benefit from deposit insurance, the CD would have to be issued by a bank or credit union.
If your CD is held within a retirement plan, it will be subject to the same restrictions as the plan in general. These may include annual limits on contributions and tax consequences for withdrawals.
Current IRA CD rate landscape
IRA CD rates vary depending on the institution and the CD you choose.
Longer-term CDs often offer higher rates than shorter-term CDs, though that isn’t always the case. As of May 2026, the national average for CD rates ranged from 0.21% to 1.55%. In this case, 1-year CDs had the highest average rate at 1.55%, while the average for 5-year CD rates was a little lower at 1.34%.
These rates fluctuate over time, based on Federal Reserve decisions, inflation trends, and other economic conditions. One advantage of a CD is that you can lock in a rate for the full term, even if interest rates fall after you open the CD. On the other hand, you could also miss out if you lock into a CD rate and then market rates rise.
Besides fluctuation over time, CD rates also vary greatly depending on who issues them. That makes it important to shop around for the best rate. CDs are available from both online and brick-and-mortar banks, and the largest banks often don’t offer the most competitive rates.
CDs vs. IRAs: A detailed comparison for retirement planning
Comparing CDs and IRAs is a little like comparing apples and oranges. They have such different characteristics that one isn’t a direct substitute for the other. Instead, they can be used separately or together as part of a retirement strategy.
CDs offer principal preservation and a predictable return, while IRAs offer tax advantages for eligible investments within the plan. These investments may include CDs. Those tax advantages depend on whether you have a traditional or a Roth IRA. Traditional IRAs generally allow investments to grow tax-deferred, with withdrawals often taxed as ordinary income. Roth IRAs are funded with after-tax dollars, but qualified withdrawals, including investment earnings, are tax-free in retirement.
The following table summarizes some leading features of CDs, traditional IRAs and Roth IRAs:
| Feature | CDs | Traditional IRAs | Roth IRAs |
|---|---|---|---|
| Tax treatment | Interest generally taxed annually as ordinary income | Tax-deferred growth | Qualified tax-free withdrawals |
| Contribution limits | Generally, no limits, though some banks may impose account limits | Annual limits. For 2026, the limit is $7,500 if you’re under 50, or $8,600 if you’re 50 or over | Annual limits. For 2026, the limit is $7,500 if you’re under 50, or $8,600 if you’re 50 or over |
| Early withdrawal | Generally, you’ll lose some of the interest earned as a penalty for withdrawals before the term is up | May be subject to a 10% penalty plus ordinary income taxes before age 59½, unless an exception applies | Depends on the type of withdrawal. A portion of withdrawals may incur a 10% penalty under some circumstances |
| FDIC insurance | Up to $250,000 per depositor at FDIC member banks | Only for eligible bank products within the IRA | Only for eligible bank products within the IRA |
| Investment options | Generally fixed interest rates, though some may offer different options | Stocks, bonds, funds, CDs, etc. | Stocks, bonds, funds, CDs, etc. |
| Best for | Capital preservation | Tax-deferred retirement savings | Tax-free retirement income |
What are the tax implications of using CDs for retirement?
Usually, the interest earned on CDs is taxed as ordinary income. For taxable CDs, paying tax on the interest reduces your after-tax return. Also, CD interest is taxable in the year that it’s earned, even though the money isn’t received until the CD matures. This can create a liquidity problem from having to pay taxes on money you haven’t yet received. However, IRA CDs have advantages that can ease these tax burdens.
Both traditional and Roth IRAs allow money to grow without annual taxation while the money remains in the account. In a traditional IRA, the growth is tax-deferred. In a Roth IRA, qualified withdrawals, including earnings, are tax-free. That means interest earned on an IRA CD would not be taxable in the year earned if you don’t take it out of the plan.
For a traditional IRA, withdrawals are generally taxed as ordinary income. Until then, though, the returns you earn can compound tax-deferred. You won’t have to pay taxes on it until you’ve actually received the money.
Roth IRAs are funded with after-tax dollars. Qualified withdrawals, including investment earnings, are tax-free.
In each case, IRA CDs combine the tax advantages of an IRA with the safety and predictable income of a CD.
FDIC insurance: Are retirement CDs protected?
As long as it’s issued by an FDIC-member bank, retirement CDs are protected by federal deposit insurance. A similar type of insurance is available from NCUA-member credit unions.
Banks do fail from time to time, but since it was created in 1933, FDIC insurance has protected every penny of covered deposits.
Deposits in CDs, savings accounts, and money market accounts are covered by deposit insurance of up to $250,000 per depositor at each bank.
Retirement CDs held within eligible IRA accounts may qualify for separate FDIC insurance coverage because certain retirement accounts are treated as a separate ownership category from single accounts. So, you can have up to $250,000 covered in taxable deposit accounts, plus get up to $250,000 of additional coverage at the same bank for an IRA CD.
How do CDs fit in a retirement planning strategy?
Retirement plans are typically diversified into different types of investments, each of which performs specific roles in the plan. Given the characteristics of CDs, where do they fit into a retirement plan?
Here’s a look at what CDs can and cannot add to your mix of retirement investments:
Safety and liquidity
With deposit insurance, CDs provide principal protection for up to $250,000 per depositor, per ownership category, per FDIC-insured bank. That safety is a good fit for later in your career when you want to shift more of your retirement assets into stable investments.
Fixed maturity dates also provide predictable liquidity. This can make them good for making sure money is available at the right time to fund your retirement spending.
Finally, if you’ve reached an age where you must take RMDs from your IRA, you may find you don’t need the entire amount of those distributions right away. While you’ll lose tax advantages once the money is distributed from the retirement plan, a CD can be a safe and predictable way to invest those distributions for short-to-intermediate periods until it’s needed.
Inflation considerations
CDs generally are not a great long-term hedge against inflation. A MyBankTracker comparison of historical CD rates from the FDIC with inflation data from the Bureau of Labor Statistics found that from 2009 to 2025, on average, 5-year CD rates trailed the annual inflation rate by more than 1%.
Because of this, here are two key tips for using CDs in a retirement plan:
- CDs are generally most appropriate for the portion of your retirement savings that prioritizes safety and liquidity. You should generally also maintain a portion of your retirement investments in more growth-oriented investments that can do better against inflation in the long run.
- It’s important to shop for the best CD rates. The most competitive rates are often well above the average rate, which can make the difference between beating inflation or not.
Choosing CDs for your retirement plans
CDs may not be the answer to all your retirement investment needs, but they can play a valuable role in providing safety, liquidity and predictable returns for a portion of your retirement assets.
When choosing CDs, try to match the term of the CD with your expected liquidity needs.
Also, shop around for the best rate. This can allow you to do much better than the average rate. Given that you may be locking in your rate for a period of years, that extra edge can make a big difference.
Frequently asked questions
Are CDs good for retirement?
CDs may be a good fit for money you expect to need in the next few years. More growth-oriented investments may be a better fit for money you’re investing for the longer term.
What CD term lengths are right for retirement investments?
This depends on when you expect to draw on your retirement savings. Creating a CD ladder that matches your expected cash flow needs can be a good way of making sure your retirement plan provides liquidity when you need it.
What happens if I withdraw from a retirement CD early?
There are two aspects to this. Taking money out of a CD before its term is up will usually cost you an early withdrawal penalty in the form of losing some of the interest you’ve earned. The other issue depends on whether you also take the money out of the retirement fund, which could involve tax consequences.
Can I put my 401(k) in a CD?
This depends on the options provided by your 401(k)plan sponsor. If your plan does give you the option of investing in a CD, you’ll only benefit from deposit insurance if that CD is held at an FDIC-member bank or NCUA-member credit union.
