Even if you\u2019re young, it\u2019s never too early to think about saving for retirement. If you have a job that offers a 401(k) savings plan, enrolling and contributing money will put you on your way to building a nice nest egg.<\/p>\n

Whether you\u2019re just starting out or you\u2019re already maxing out your 401(k) contributions \u2014 more on that in a minute \u2014 it\u2019s helpful to understand how the plans work, what the rules are and your alternatives if your employer doesn\u2019t offer a 401(k).<\/p>\n

Earn Easy Money to Boost Your Retirement Savings<\/h2>\n

We already know a 401(k) can help us live well in retirement; it\u2019s the saving part that can be challenging. But saving is integral to retirement, even if you\u2019re decades away from clocking out for the last time. If you\u2019re looking to pad your retirement savings with some extra money, try one of our favorite ways to make quick cash.<\/p>\n

What Is a 401(k) and How Does it Work?<\/h2>\n

So what is a 401(k) anyway? A 401(k) is an employer-sponsored investment plan designed to give you a tax break on your retirement investing.<\/span><\/p>\n

The idea is that you, the employee, allot a certain amount of your paycheck to go straight into your 401(k). You can do this pre- or post-tax.<\/span><\/p>\n

It\u2019s up to you how much you want to put in, though the contribution limit for 2025 is $24,500 of your own money per year. That\u2019s up from the 2025 limit of $23,500.<\/span><\/p>\n

Once you turn 50, you can make an additional catch-up contribution of $8,000 (as of 2026). Thanks to the SECURE 2.0 Act, employees who are 60, 61, 62 and 63 who participate in these plans have a higher limit ($11,250 instead of $8,000 in 2025).<\/span><\/p>\n

Those catch-up contributions allow you to build your 401(k) even more as you get closer to retirement.<\/span><\/p>\n

The best feature of a 401(k): Many employers will match your contributions up to a certain percentage.<\/p>\n

What Does 401(k) Stand For?<\/h3>\n

The name 401(k) has no hidden meaning. It\u2019s a section of the tax code introduced in 1978 designed to make it easier for employers to help their workers get in good financial shape for their retirement years.<\/p>\n

The man behind the 401(k), Ted Benna, told Workforce<\/a> he had no clue that it would become the main way people save for retirement some 40 years later. Yet, here we are.<\/p>\n

Benefits of a 401(k)<\/h2>\n

While a 401(k) carries risks just like all investing, it\u2019s an unequivocally smart move to contribute to one. It\u2019s like paying yourself in retirement.<\/p>\n

Here are some of the best perks.<\/p>\n

Matching Contributions<\/h3>\n

One of the best things about a 401(k) is that many employers match your contribution.<\/p>\n

Say your employer offers to match 100% of your 401(k) contributions up to 6% of your income. If you make $40,000 per year and max out the employer match, you\u2019d put in $2,400 and your employer would kick in another $2,400.<\/p>\n

Think of your employer\u2019s match as a part of your compensation package.<\/p>\n

You Can Automate Your Savings<\/h3>\n

A 401(k) is an easy way to save for retirement without realizing you\u2019re doing it. The money automatically comes out of each paycheck, so you never miss it.<\/p>\n

Since your employer is your 401(k) plan sponsor, the fees are usually less than if you set up a retirement account on your own. As with group rates on health insurance, your company can negotiate fees for things like mutual fund managers or financial advisers.<\/p>\n

Upfront Tax Break<\/h3>\n

When you put money in a traditional 401(k), you\u2019re deferring part of your salary until you retire. That means the money you contribute now doesn\u2019t count as taxable income. You\u2019ll pay taxes on it later on when you withdraw it.<\/p>\n

401(k) Drawbacks<\/h2>\n

You also need to be aware of what you can\u2019t do with a 401(k), and the rules governing contributions and withdrawals.<\/p>\n

Limited Investment Options<\/h3>\n

A 401(k) typically has more limited investment options than other retirement accounts. You can\u2019t pick individual stocks and bonds to invest in.<\/p>\n

This is not necessarily a drawback if you\u2019re unfamiliar with investing and are happy to have an expert do it for you. You\u2019ll usually get several mutual funds to choose from, though more plans are starting to offer exchange-traded funds (ETFs).<\/p>\n

A 401(k) isn\u2019t a vehicle for playing the stock market, but rather for building wealth, based on your risk tolerance, over the long term.<\/p>\n

Early Withdrawal Penalties<\/h3>\n

Because a 401(k) is meant to provide you income in retirement, there are penalties for withdrawing the funds early.<\/p>\n

If you take money from your 401(k) before age 59 1\/2, save a few exceptions such as becoming disabled, you\u2019ll pay a 10% penalty and owe income taxes on what you take out. If you leave your job for any reason when you\u2019re 55 or older, you can also avoid the 10% penalty on withdrawals from your current plan.<\/p>\n

Some plans also allow you to take what\u2019s called a hardship withdrawal for situations like medical expenses or avoiding foreclosure, but it will be limited to the money you have put in. You can\u2019t withdraw the earnings, and in most circumstances, you\u2019ll still be subject to that 10% penalty.<\/p>\n

You can also borrow from your 401(k) under certain circumstances. But just like any other loan, you\u2019ll have to repay it with interest. If you leave your job for any reason, you\u2019ll have to pay it back in full when you file your tax return for the year. Otherwise, it will be treated as an early distribution, which means you get hit with taxes and the 10% penalty.<\/span><\/p>\n

The bottom line: Don\u2019t treat your 401(k) like a savings account. It\u2019s important to have an emergency fund in addition to a retirement plan.<\/p>\n

Vesting<\/h3>\n

You might come across the term \u201cvesting\u201d when signing up for your 401(k). This refers to how long you need to work for your company before you own all the funds in the account.<\/p>\n

Say your company\u2019s vesting schedule is two years. If you quit before that, you would forfeit the employer-contributed funds in the account, though any contributions you made would remain yours. That\u2019s an incentive to stick around until you\u2019re fully vested.<\/p>\n

How Do 401(k) Taxes Work?<\/h2>\n

Taxes for your 401(k) work in one of two ways. In a traditional 401(k), you make pretax contributions. With this type of account, you\u2019ll pay taxes when you withdraw the funds after retirement.<\/p>\n

Another option is a Roth 401(k), which taxes the contributions you make. That means you withdraw the money tax-free upon retirement.<\/p>\n

Traditional or Roth?<\/h3>\n

Before deciding between a traditional and a Roth 401(k), consider your current tax bracket and the one you expect to be in during retirement.<\/p>\n

Most people will be in a lower tax bracket when they retire because their retirement income will be less than their salary while working. In this case, you might choose to stick with a traditional 401(k).<\/p>\n

You might have the option to invest in a Roth 401(k), which allows you to invest money you\u2019ve paid taxes on in exchange for tax-free withdrawals in retirement. However, your employer\u2019s contributions are always pre-tax, so you\u2019ll be taxed when you withdraw the money. Check with your employer to see if this is possible.<\/p>\n

Ultimately, the decision is yours, though it\u2019s a good idea to speak with a financial adviser to determine what\u2019s right for you.<\/p>\n

What Happens to Your 401(k) When You Quit?<\/h2>\n

Since a 401(k) is an employer-based retirement plan, you\u2019re probably wondering what happens to the money if you quit your job.<\/p>\n

While your employer sponsors your account, it doesn\u2019t own it. You own the account, and it\u2019s often managed by a third-party administrator. If you quit or are fired, your money stays in the account. It will continue to grow and earn money, but you can\u2019t make more contributions to it unless you roll over your 401(k) into a new employer\u2019s plan or an individual retirement account (IRA)<\/span>.<\/p>\n

Rolling over your old 401(k) into a new one is a seamless way to continue saving for retirement.<\/p>\n

\u201cFor many people, having everything automated through their employer\u2019s 401(k) plan is the only reason they have the discipline to save every month,\u201d said Paul Ruedi Jr., a certified financial planner in Plano, Texas, who specializes in retirement planning.<\/p>\n

If you roll it over into an IRA, you\u2019ll be responsible for making contributions on your own. But remember, if your new employer offers a 401(k) with a matching percentage, you should strongly consider enrolling and contributing at least up to the match.<\/p>\n

\n

Drowning in Expenses?<\/h3>\n

Maybe you\u2019re scrambling after your car broke down. Or you got a medical bill you weren\u2019t expecting. Or inflation has finally pushed your budget over the edge. Take a breath. You don\u2019t need to go it alone.<\/p>\n

When money is tight, these resources<\/a> can help you manage unexpected expenses without stress.<\/p>\n<\/div>\n

401(k) Investment Categories<\/h2>\n

A 401(k) helps build your retirement savings by investing your money. You can choose to have complete control over where your money is invested or pick general categories and leave the decisions up to your broker.<\/p>\n

Most 401(k) plans have four main investment categories.<\/p>\n

Stocks<\/h3>\n

Your company\u2019s 401(k) may allow you to invest in stocks. If this option is available, you\u2019ll likely be able to purchase only company stock. Individual stocks may be an option if your plan has a broker.<\/p>\n

Stock Mutual Funds<\/h3>\n

A stock mutual fund, which is a more common option, allows you to invest in a pre-set pool of stocks rather than individual stocks for a more diverse portfolio with less risk.<\/p>\n

Bond Mutual Funds<\/h3>\n

Similar to a stock mutual fund, a bond mutual fund allows investment in hundreds of bonds, which is less risky than investing in individual bonds.<\/p>\n

Variable Annuities<\/h3>\n

Unlike stocks and bonds, annuities give out regular payments once you make an initial upfront investment.<\/p>\n

The younger you are, the more risk you can afford to take with your investments. But if you\u2019re nearing retirement age, riskier investments could result in you losing the money you need to live on.<\/p>\n

The mix of investments you choose for your 401(k) is up to you, but you should take a few things into account, including your age. Stocks are riskier than bonds, so your 401(k) will likely be heavier with stock investments when you\u2019re younger and switch over to higher bond investments as you get closer to retirement.<\/p>\n

What if I Can\u2019t Get a 401(k)?<\/h2>\n

What is a 401(k) alternative if you\u2019re not eligible for one? If your company doesn\u2019t offer one, or if you\u2019re an independent contractor, you can still save for retirement. The most common way is via an IRA.<\/span><\/p>\n

Like 401(k) plans, you can choose between a <\/span>traditional IRA or a Roth IRA. An IRA limits how much you can save per year. For 2025, the limit is $7,000, and for people aged 50 or older is $8,000.<\/span><\/p>\n

Even if you have an employer-sponsored 401(k), you should still consider opening an IRA to supplement your retirement. To diversify the income you\u2019ll have in retirement, consider contributing to your 401(k) at least up to the employer match, and then open a Roth IRA and put as much as you can in that. Then, when you\u2019re withdrawing funds in retirement, you\u2019ll owe taxes only on the distributions from your traditional 401(k). Remember, with a Roth, withdrawals are tax free.<\/p>\n

Is a 401(k) a Good Idea?<\/h2>\n

That\u2019s easy: Yes.<\/p>\n

A 401(k) is an ideal first step to saving for retirement. If your employer offers one, look into maxing out the amount it will match, and consider contributing more money each month or opening an IRA too.<\/p>\n

Your retired self will be endlessly grateful.<\/p>\n
