According to Federal Reserve data, 61 percent of U.S. adults have a tax-preferred retirement account such as a 401(k) or individual retirement account (IRA). Since their introduction in the 1970s, these savings vehicles — built by our contributions and expanded by investment returns — have become a cornerstone of Americans’ retirement security. How much do you know about how IRAs and 401(k)s work and how they differ? Take our quiz to find out.

Question 1 of 10

A 401(k) plan differs from an individual retirement account (IRA) because:

The main difference between 401(k) plans and traditional IRAs is that 401(k)s are tied to your workplace. Most employers that provide savings plans offer to match a portion of workers’ contributions, typically around 4 percent to 5 percent of gross pay. IRAs are individual accounts you can open yourself with a bank, brokerage or other financial institution.

Question 2 of 10

True or false: You must make an initial investment to open an IRA.

There is no legal minimum amount needed to start an IRA, and many financial institutions do not require any initial deposit (although some do have a minimum investment, so be sure to ask the provider).

Question 3 of 10

Who created the Roth IRA?

The Roth IRA was established by the Taxpayer Relief Act of 1997 and named for the bill’s chief legislative sponsor, the late Sen. William Roth of Delaware. The key element of Roths — taxing contributions going in so that the money you withdraw in retirement is tax-free — was expanded to workplace plans in 2006 and many employers now offer Roth 401(k)s.

Question 4 of 10

What does “auto-escalation” mean with a 401(k)?

Workplace retirement plans with auto-escalation boost your contribution by a set amount each year, typically 1 percent, up to a limit set by your employer. Businesses that have established a 401(k) since Dec. 29, 2022, are required to automatically enroll qualifying employees and implement auto-escalation by default.

Question 5 of 10

True or false: If you take money out of a 401(k) or IRA before age 59 1/2, you can be penalized for the withdrawal.

Early withdrawals from most retirement accounts are subject to a 10 percent penalty on the amount you take out, along with regular income taxes. There are limited exceptions for financial need or withdrawals for certain purposes, such as disaster recovery, a first-time home purchase, or birth or adoption expenses.

Question 6 of 10

How much can you take out of a 401(k), without penalty, to cover a financial emergency?

Since 2024, federal law has allowed 401(k) owners younger than 59½ to withdraw up to $1,000, penalty-free, for “unforeseeable or immediate financial needs relating to necessary personal or family emergency expenses.” (You’ll still owe taxes on the money.) You can make one such withdrawal a year and can’t make another for the next three years unless you pay the money back.

Question 7 of 10

Retirement savings can be invested in various vehicles, including stocks, bonds, mutual funds and cash. Which of these factors should you consider when setting or changing your investment mix?

Investment goals and strategies typically shift as you get closer to retirement. Generally, people put more of their retirement savings into stocks when they are younger to book in years of higher returns, then shift to less risky assets like bonds as they near retirement to safeguard their nest egg. But how much you leave in stocks may depend on your tolerance for the market's ups and downs.

Question 8 of 10

Sally is 55. What’s the most she can contribute to a 401(k) in 2025?

The standard 401(k) contribution cap in 2025 is $23,500, but savers like Sally who are 50 or older can make additional “catch-up” contributions of up to $7,500, for a total of $31,000. Starting in 2025, 401(k) account holders ages 60 to 63 can make even bigger catch-up contributions — up to $11,250, for a maximum contribution of $34,250. 

Question 9 of 10

True or false: Part-time workers are not eligible for 401(k)s.

Federal legislation passed in recent years requires employers who offer a workplace retirement plan to make it available to part-time staff who work at least 1,000 hours for one year or 500 hours for two consecutive years. 

Question 10 of 10

At what age are you required to make withdrawals from a traditional retirement account?

If you have a traditional IRA or 401(k), you must take required minimum distributions (RMDs) annually starting at age 73. Roth IRAs and 401(k)s are not subject to RMDs while the original owner is alive but generally will be if the account is passed on to an heir.
