Investing in an IRA vs. CD vs. Money Market Account

When comparing options like individual retirement accounts (IRAs), certificates of deposit (CDs) and money market accounts, it’s important to understand how each can fit into your financial strategy. While you cannot directly invest in an IRA itself, you can hold investments like CDs or money market accounts within one. These options also have major differences when it comes to tax advantages and implications, liquidity and accessibility and growth potential. Read on for a full breakdown of what each option offers and how they differ.

What Is an IRA?

An IRA is a tax-advantaged account designed to help individuals save for retirement. IRAs allow you to hold various types of investments, including:

Stocks
Bonds
Mutual funds
CDs
Money market accounts

There are several types of IRAs, including traditional and Roth IRAs. With a traditional IRA, contributions may be tax-deductible, and income tax is deferred until withdrawals are made during retirement. Roth IRA contributions, on the other hand, are made with after-tax dollars. As a result, qualified withdrawals are tax-free.

Contribution Limits and Eligibility

For 2026, the IRA contribution limit is $7,500 for people under 50, and $8,600 for people age 50 and older. These limits apply across all IRAs. If you have both a traditional and Roth IRA, your total combined contributions cannot exceed this limit.

Roth IRA contribution rules are subject to income phase-out ranges. These begin at $153,000 for single filers and $242,000 for married couples filing jointly as of 2026. If your income falls within these ranges, the amount you can contribute to a Roth IRA gradually decreases until it’s phased out entirely. Once your income exceeds the upper limit, you can no longer contribute directly to a Roth IRA.

However, higher earners may still be able to take advantage of Roth benefits through a backdoor Roth IRA conversion. This involves contributing to a traditional IRA and then converting those funds to a Roth IRA, allowing you to bypass income limits. It’s important to understand the potential tax consequences of this strategy before proceeding, though. The conversion amount is generally subject to income tax in the year you complete it.

If you have a traditional IRA, you’ll need to take required minimum distributions upon turning 73. SmartAsset’s RMD Calculator can estimate how much you’ll have to withdraw.

About This Calculator

This calculator estimates RMDs by dividing the user's prior year's Dec. 31 account balance by the IRS Distribution Period based on their age. Users can enter their birth year, prior-year balances and an expected annual return to estimate the timing and amount of future RMDs.

For IRAs (excluding Roth IRAs), users may combine balances and take the total RMD from one or more accounts. For 401(k)s and similar workplace plans*, RMDs must be calculated and taken separately from each account, so balances should be entered individually.

^*The IRS allows those with multiple 403(b) accounts to aggregate their balances and split their RMDs across these accounts.

Assumptions

This calculator assumes users have an RMD age of either 73 or 75. Users born between 1951 and 1959 are required to take their first RMD by April 1 of the year following their 73rd birthday. Users born in 1960 and later must take their first RMD by April 1 of the year following their 75th birthday.

This calculator uses the IRS Uniform Lifetime Table to estimate RMDs. This table generally applies to account owners age 73 or older whose spouse is either less than 10 years younger or not their sole primary beneficiary.

However, if a user's spouse is more than 10 years younger and is their sole primary beneficiary, the IRS Joint and Last Survivor Expectancy Table must be used instead. Likewise, if the user is the beneficiary of an inherited IRA or retirement account, RMDs must be calculated using the IRS Single Life Expectancy Table. In these cases, users will need to calculate their RMD manually or consult a finance professional.

For users already required to take an RMD for the current year, the calculator uses their account balance as of December 31 of the previous year to compute the RMD. For users who haven't yet reached RMD age, the calculator applies their expected annual rate of return to that same prior-year-end balance to project future balances, which are then used to estimate RMDs.

This RMD calculator uses the IRS Uniform Lifetime Table, but certain users may need to use a different IRS table depending on their beneficiary designation or marital status. It's the user's responsibility to confirm which table applies to their situation, and tables may be subject to change.

Actual results may vary based on individual circumstances, future account performance and changes in tax laws or IRS regulations. Estimates provided by this calculator do not guarantee future distribution amounts or account balances. Past performance is not indicative of future results.

Tax Considerations and Withdrawals

IRAs offer tax advantages that can significantly impact retirement savings. With a traditional IRA, taxes are deferred until funds are withdrawn. Typically this after age 59½, to avoid penalties. Roth IRAs, on the other hand, allow for tax-free withdrawals under the right conditions.

It is also worth noting that required minimum distributions (RMDs) apply to traditional IRAs starting at age 73 (age 75 for people born in 1960 or later). If you own a Roth IRA, however, you won’t have RMDs during your lifetime.

What Is a CD?

A CD is a time deposit account offered by banks and credit unions that pays interest on funds held for a fixed term. When you invest in a CD, you leave your money in the account for a set period, whether months or years, in exchange for earning interest.

Interest Rates and Penalties

CDs generally provide a higher interest rate than standard savings accounts. At the same time, they deliver a low-risk return since the rate remains fixed for the entire term. This can be particularly appealing in a declining interest rate environment.

Withdrawing funds from a CD before the maturity date will usually incur a penalty. This can reduce the overall earnings. As a result, CDs are often a good fit for individuals who do not need immediate access to funds.

What Is a Money Market Account?

A money market account is a type of savings account that typically pays more interest than regular savings accounts. They are offered by banks and credit unions and are insured by the FDIC or the NCUA, providing a safe place to store your money.

Money market accounts often come with check-writing privileges and debit card access. This makes them more flexible than CDs, which usually require you to lock in your funds for a set period.

You should note that many people confuse this kind of savings account with a money market fund. A money market fund is an investment product that invests in low-risk securities. It is not FDIC-insured.

Interest Rates and Access

The interest rates on money market accounts vary based on financial institution and current market conditions. While they generally offer better rates than standard savings accounts, they may not always match the potential returns of other investment vehicles, including CDs.

However, the liquidity of money market accounts is a significant advantage. You can typically withdraw funds up to six or fewer times per month without penalties.

IRA vs. CD vs. Money Market Accounts

There are certain factors to consider when deciding whether to hold investments like CDs and money market accounts inside an IRA or separately.

Tax Advantages vs. Flexibility

IRAs, whether traditional or Roth, offer specific tax benefits that neither CDs nor money market accounts provide. On the flip side, IRAs also include penalties for taking early withdrawals before retirement age. CDs and money market accounts outside of an IRA, on the other hand, allow easier access to funds but offer no tax advantages.

Growth Potential vs. Stability

IRAs provide access to a broad range of investment options. This can include CDs and money market accounts but also stocks, bonds and mutual funds, which can offer higher growth potential over time.

CDs and money market accounts, whether held inside or outside an IRA, are generally more generally stable but offer limited growth potential when compared with higher-risk investments held within an IRA. CDs are locked in at a fixed interest rate, providing earnings in exchange for stability. Money market accounts sit somewhere in the middle, offering a modest return with more flexibility.

Liquidity and Accessibility

Money market accounts allow for frequent withdrawals, although they may be subject to limits. CDs require you to lock your money away for a set period, with penalties for early withdrawal. Investments held in an IRA, including CDs and money market accounts, are generally less accessible due to early withdrawal penalties, which apply before retirement age.

If you need immediate access to funds, money market accounts provide the most flexibility. IRAs, in contrast, are more suited for long-term growth goals.

Should You Hold a CD or Money Market Account Inside an IRA?

One point that often causes confusion is that an IRA is an account. A CD and a money market account are investments that you can hold within that account. Whether or not it makes sense to hold those investments within an IRA depends largely on when you expect to use the money.

If you’re decades away from retirement, dedicating a large portion of an IRA to CDs or money market accounts may limit the account’s long-term growth potential. While these investments can help preserve principal, they have historically produced lower returns than diversified stock portfolios over long periods.

As retirement approaches, however, the role of lower-risk investments may begin to change. Some investors shift a portion of their IRA into CDs or money market accounts to reduce portfolio volatility or to set aside money they expect to withdraw within the next few years. Doing so can help reduce the need to sell off stocks after a market decline to meet retirement spending needs.

Outside an IRA, CDs and money market accounts often serve different purposes. A CD may be appropriate for money earmarked for a known future expense. Meanwhile, a money market account can provide a place to keep cash that needs to remain readily available. Deciding whether to hold either investment inside or outside an IRA depends not only on the investment itself, but also on the intended purpose for that money.

Who Should Choose Which Option?

When deciding between investing in an IRA vs. CD vs. money market account, it helps to consider factors like your financial goals, time horizon, risk tolerance and need for liquidity. Each option serves a different purpose, and understanding what those are can help you make the right choice.

IRA: Best for long-term, tax-conscious investors who are specifically saving for retirement. If you’re looking to grow your wealth over decades and take advantage of tax benefits, an IRA is a strong choice.
CD: Ideal for risk-averse savers with medium-term goals who don’t need immediate access to their money. If you have cash you can lock away for a set period in exchange for a guaranteed return, a CD is a safe and predictable option.
Money market account: A good fit for people who need short-term liquidity but still want to earn some interest. If you’re building an emergency fund or want easy access to your savings with less risk, a money market account offers flexibility and security.

Financial Goal	Best Option	Why?
Saving for retirement with tax benefits	IRA	Long-term growth potential with tax advantages
Medium-term savings (1–5 years)	CD	Fixed return and principal protection
Emergency fund or short-term savings	Money Market Account	High liquidity and FDIC-insured safety

Bottom Line

A couple updating documents with a financial advisor for their financial plan.

When comparing IRAs vs. CDs vs. money market accounts, it is important to consider factors like potential tax benefits, liquidity and returns. Inside an IRA, both CDs and money market accounts gain the tax advantages of the IRA, but withdrawals before retirement may incur penalties. Outside an IRA, CDs offer secure, low-risk returns with fixed interest, but early withdrawals may still incur penalties. Money market accounts outside an IRA provide more liquidity and easier access to funds, while inside an IRA, they offer the same tax benefits but are subject to IRA withdrawal rules.
