How Much Should You Contribute to Your 401(k)?

Short answer: How much you should contribute to your 401(k) depends on your budget and goals, but the first target is the same for almost everyone: put in at least enough to get your employer's full match. After that, raise your contribution rate a little each year. For 2026, the IRS lets you contribute up to $24,500, or more if you're 50 or older.

How Much Should I Contribute to My 401(k)? A Step-by-Step Approach

There's no single percentage that fits everyone. Your age, income, existing savings and other bills all matter. Most workers can still use the same order of steps:

1. Find your employer's match formula. Your plan documents or HR department can tell you how the match works. The U.S. Department of Labor suggests finding out how much you would need to contribute to get the full employer contribution.
2. Contribute at least enough to get the full match. Matching money is part of your total compensation. If you contribute less than the amount that earns the full match, you give up some of it.
3. Check your vesting schedule. It tells you when the matching money becomes yours to keep.
4. Raise your rate over time. Many plans let you set automatic yearly increases. The Labor Department notes you can start small and increase the amount over time.
5. Work toward the annual limit if your budget allows. For 2026, the employee limit is $24,500, with catch-up room at 50 and older.

Why Should You Get the Full Employer Match First?

An employer match adds money to your account on top of what you save. The Labor Department's retirement guide puts it simply: if your employer offers a plan such as a 401(k), sign up, and your company may kick in more.

Match formulas vary from plan to plan. As a hypothetical example, suppose a plan matches 50 cents for every dollar you contribute, up to 6% of your pay. On a $50,000 salary:

You contribute	Your yearly contribution	Hypothetical employer match	Total going in
3% of pay	$1,500	$750	$2,250
6% of pay	$3,000	$1,500	$4,500
10% of pay	$5,000	$1,500	$6,500

In this example, moving from 3% to 6% doubles the match. Going above 6% still adds to your savings, but the match stops growing. Your plan's formula may be different, so plug in your own numbers.

When Does the Employer Match Become Yours?

Your own contributions (elective deferrals) are always 100% vested. That money is yours even if you leave the job the next day.

Employer matching contributions can come with a vesting schedule. The IRS describes two schedules that are the slowest a plan is allowed to use:

Schedule	How it works
3-year cliff	0% vested until 3 years of service, then 100%
6-year graded	20% after 2 years, 40% after 3, 60% after 4, 80% after 5 and 100% after 6

Plans can vest faster, including right away. If you're thinking about changing jobs, check how much of your match is vested first. It can affect when you decide to leave.

How Much Should I Put in My 401(k) If I Was Auto-Enrolled?

Being auto-enrolled doesn't mean your contribution rate is right for you. It's a starting point.

Under a SECURE 2.0 rule, 401(k) and 403(b) plans established after Dec. 29, 2022, must generally auto-enroll new employees beginning with the 2025 plan year. According to the IRS, unless an employee opts out, the plan must:

• Start the employee at a contribution rate of at least 3% of pay.
• Raise that rate by one percentage point each year until it reaches at least 10% of pay.

There are exceptions for new and small businesses, church plans and governmental plans. You can change your rate or opt out. If your plan's default rate is below the amount that earns your full match, raising it yourself is usually the first change to make.

What Is the Most You Can Contribute to a 401(k) in 2026?

The IRS sets the limits each year. For 2026:

Your age in 2026	Employee limit	Catch-up	Total you can contribute
Under 50	$24,500	None	$24,500
50 to 59, or 64 and older	$24,500	$8,000	$32,500
60 to 63	$24,500	$11,250	$35,750

The same $24,500 limit applies to 403(b) plans, most governmental 457 plans and the federal Thrift Savings Plan. For the full rules, see our guide to 401(k) and IRA contribution limits for 2026.

How Much Retirement Income Will You Need?

The Labor Department's retirement guide says experts estimate you'll need 70% to 90% of your preretirement income to keep your standard of living when you stop working. Social Security and any other income will cover part of that. Your savings will need to cover the rest.

That's why the right contribution rate is a personal number. Someone who starts saving at 25 has more time for money to grow than someone who starts at 45. The Labor Department notes that the sooner you start saving, the more time your money has to grow. Our retirement savings calculator shows how different contribution rates could add up by the age you plan to retire.

Should You Contribute More, or Save Somewhere Else First?

Once you're getting the full match, the next dollar could go to your 401(k) or to another goal. Questions to weigh:

• Do you have emergency savings? Money in a 401(k) is meant for retirement. The Labor Department warns that if you withdraw retirement savings early, you lose principal and interest, may lose tax benefits and may owe withdrawal penalties.
• Do you carry high-interest debt? Paying it down may come before raising contributions above the match.
• Do you have a health savings account? If you have a high-deductible health plan, an HSA is another tax-advantaged option. See our HSA vs. FSA guide.
• Could you qualify for the Saver's Credit? This IRS tax credit is for low- and moderate-income savers who contribute to a workplace plan or IRA. For 2026, the income limit is $80,500 for married couples filing jointly, $60,375 for heads of household and $40,250 for single filers and married people filing separately.

How Do You Change Your 401(k) Contribution?

Most plans let you change your contribution rate at any time, though some limit how often or when changes take effect. The steps usually look like this:

1. Log in to your plan's website or app, or ask your HR or benefits office for the form.
2. Choose a percentage of pay or a dollar amount. A percentage rises automatically when your pay goes up.
3. Turn on automatic increases if your plan offers them. A small yearly increase can be easier to fit into your budget, especially if it's timed with a raise.
4. Check how your money is invested. If you were auto-enrolled, your contributions may be going into the plan's default investment.
5. Look at your next pay stub. Confirm the new amount came out and that the match shows up on your account statement.

Review your rate at least once a year, and again after a raise, a job change or a big change in expenses.

The Bottom Line

Start with enough to get your full employer match, check when that match vests, and raise your contribution rate over time toward the 2026 limit of $24,500. Auto-enrollment is a starting point, not a plan. If you want help setting a target, a fee-only fiduciary adviser can review your whole picture.

Frequently asked questions

How much should I contribute to my 401(k)?

Start with at least enough to get your employer's full match, since that money is part of your total compensation. Then raise your contribution rate over time, for example by 1 percentage point a year, as your budget allows. The legal maximum for 2026 is $24,500 for workers under 50.

How much should I put in my 401(k) if my employer doesn't match?

Without a match, you still get the plan's tax benefits and automatic payroll saving. How much to put in depends on your other goals, such as an emergency fund or paying off high-interest debt, and on whether an IRA would suit you better. The amount is up to you, up to the annual IRS limit.

Is 10% a good 401(k) contribution?

There's no single right percentage. For newer plans that auto-enroll employees, federal rules use 10% of pay as the minimum level that automatic increases must reach. Whether 10% is enough for you depends on your age, what you've already saved and the retirement income you'll need.

Do I keep my employer match if I leave my job?

You keep the vested part. Your own contributions are always fully vested. Matching contributions follow your plan's vesting schedule, which can be up to a 3-year cliff or a 6-year graded schedule. Your plan documents show the schedule.

What is the most I can contribute to a 401(k) in 2026?

The 2026 employee contribution limit is $24,500. Workers 50 and older can add an $8,000 catch-up, for $32,500 in total. Workers aged 60, 61, 62 or 63 have a higher catch-up of $11,250 instead, for $35,750 in total.
