Once you set up your retirement plan at work, the next natural question is: How much to contribute to a 401(k)? While there’s no ironclad answer for how much to save in your employer-sponsored plan, there are some important guidelines that can help you set aside the amount that’s right for you, such as the tax implications, your employer match (if there is one), the stage of your career, your own retirement goals, and more.

Here’s what you need to think about when deciding how much to contribute to your 401(k).

401(k) Contribution Limits for 2024 and 2025

Like most tax-advantaged retirement plans, 401(k) plans come with caps on how much you can contribute. The IRS puts restrictions on the amount that you, the employee, can save in your 401(k); plus there is a cap on total employee-plus-employer contributions.

For tax year 2024, the contribution limit is $23,000, with an additional $7,500 catch-up provision for those 50 and older, for a total of $30,500. The combined employer-plus-employee contribution limit for 2024 is $69,000 ($76,500 with the catch-up amount).

The limits go up for tax year 2025. The 401(k) contribution limit in 2025 is $23,500, with an additional $7,500 catch-up provision for those 50 and older, for a total of $31,000. The combined employer-plus-employee contribution limit for 2025 is $70,000 ($77,500 with the catch-up amount).

Also in 2025, there is an extra 401(k) catch-up for those aged 60 to 63. Thanks to SECURE 2.0, these individuals can contribute $11,250 instead of the standard catch-up of $7,500, for a total of $81,250.

How Much Should You Put Toward a 401(k)?

Next you may be thinking, now I know the retirement contribution limits, but how much should I contribute to my 401(k)? Here are some guidelines to keep in mind as you’re deciding on your contribution amount.

When You’re Starting Out in Your Career

At this stage, you may be starting out with a lower salary and you also likely have commitments to pay for, like rent, food, and maybe student loans. So you may decide to contribute a smaller amount to your 401(k). If you can, however, contribute enough to get the employer match, if your employer offers one.

Here’s how it works: Some employers offer a matching contribution, where they “match” part of the amount you’re saving and add that to your 401(k) account. A common employer match might be 50% up to the first 6% you save.

In that scenario, let’s say your salary is $100,000 and your employer matches 50% of the first 6% you contribute to your 401(k). If you contribute up to the matching amount, you get the full employer contribution. It’s essentially “free” money, as they say.

To give an example, if you contribute 6% of your $100,000 salary to your 401(k), that’s $6,000 per year. Your employer’s match of 50% of that first 6%, or $6,000, comes to $3,000 for a total of $9,000.

As You Move Up in Your Career

At this stage of life you likely have a lot of financial obligations such as a mortgage, car payments, and possibly child care. It may be tough to also save for retirement, but it’s important not to fall behind. Try to contribute a little more to your 401(k) each year if you can — even 1% more annually can make a difference.

That means if you’re contributing 6% this year, next year contribute 7%. And the year after that bump up your contribution to 8%, and so on until you reach the maximum amount you can contribute. Some 401(k) plans have an auto escalation option that will automate the extra savings for you, to make the process even easier and more seamless. Check your plan to see if it has such a feature.

As You Get Closer to Retirement

Once you reach age 50, you’ll likely want to figure out how much you might need for retirement so you have a specific goal to aim for. To help reach your goal, consider maxing out your 401(k) at this time and also make catch-up contributions if necessary.

Maxing out your 401(k) means contributing the full amount allowed. For 2025, that’s $23,500 for those 49 and under. If, at 50, you haven’t been contributing as much as you wish you had in previous years, you can also contribute the catch-up contribution of $7,500. So you’d be saving $31,000 for retirement in your 401(k) in 2025. With the potential of compounding returns, maxing out your 401(k) until you reach full retirement age of 67 could go a long way to helping you achieve financial security in retirement.

The Impact of Contributing More Over Time

The earlier you start saving for retirement, the more time your money will potentially have to grow, thanks to the power of compounding returns, as mentioned above.

In addition, by increasing your 401(k) contributions each year, even by just 1% annually, the savings could really add up. For instance, consider a 35-year-old making $60,000 who contributes 1% more each year until their full retirement age of 67. Assuming a 5.5% annual return and a modest regular increase in salary, they could potentially save more than an additional $85,000 for retirement.

That’s just an example, but you get the idea. Increasing your savings even by a modest amount over the years may be a powerful tool in helping you realize your retirement goals.

Factors That May Impact Your Decision

In addition to the general ideas above for the different stages of your life and career, it’s also wise to think about taxes, your employer contribution, your own goals, and more when deciding how much to contribute to your 401(k).

1. The Tax Effect

The key fact to remember about 401(k) plans is that they are tax-deferred accounts, and they are considered qualified retirement plans under ERISA (Employment Retirement Income Security Act) rules.

That means: The money you set aside is typically deducted from your paycheck pre-tax, and it grows in the account tax free — but you pay taxes on any money you withdraw. (In most cases, you’ll withdraw the money for retirement expenses, but there are some cases where you might have to take an early 401(k) withdrawal. In either case, you’ll owe taxes on those distributions.)

The tax implications are important here because the money you contribute effectively reduces your taxable income for that year, and potentially lowers your tax bill.

Let’s imagine that you’re earning $100,000 per year, and you’re able to save the full $23,000 allowed by the IRS for 2024. Your taxable income would be reduced from $100,000 to $77,000, thus putting you in a lower tax bracket.

2. Your Earning Situation

One rule-of-thumb is to save at least 10% of your annual income for retirement. So if you earn $100,000, you’d aim to set aside at least $10,000. But 10% is only a general guideline. In some cases, depending on your income and other factors, 10% may not be enough to get you on track for a secure retirement, and you may want to aim for more than that to make sure your savings will last given the cost of living longer.

For instance, consider the following:

•   Are you the sole or primary household earner?

•   Are you saving for your retirement alone, or for your spouse’s/partner’s retirement as well?

•   When do you and your spouse/partner want to retire?

If you are the primary earner, and the amount you’re saving is meant to cover retirement for two, that’s a different equation than if you were covering just your own retirement. In this case, you might want to save more than 10%.

However, if you’re not the primary earner and/or your spouse also has a retirement account, setting aside 10% might be adequate. For example, if the two of you are each saving 10%, for a combined 20% of your gross income, that may be sufficient for your retirement needs.

All of this should be considered in light of when you hope to retire, as that deadline would also impact how much you might save as well as how much you might need to spend.

3. Your Retirement Goals

What sort of retirement do you envision for yourself? Even if you’re years away from retirement, it’s a good idea to sit down and imagine what your later years might look like. These retirement dreams and goals can inform the amount you want to save.

Goals may include thoughts of travel, moving to another country, starting your own small business, offering financial help to your family, leaving a legacy, and more.

You may also want to consider health factors, as health costs and the need for long-term care can be a big expense as you age.

4. Do You Have Debt?

It can be hard to prioritize saving if you have debt. You may want to pay off your debt as quickly as possible, then turn your attention toward saving for the future.

The reality is, though, that debt and savings are both priorities and need to be balanced. It’s not ideal to put one above the other, but rather to find ways to keep saving even small amounts as you work to get out of debt.

Then, as you pay down the money you owe — whether from credit cards or student loans or another source — you can take the cash that frees up and add that to your savings.

The Takeaway

Many people wonder how much to contribute to a 401(k). There are a number of factors that will influence your decision. First, there are the contribution limits imposed by the IRS.

While few people can start their 401(k) journey by saving quite that much, it’s wise, if possible, to contribute enough to get your employer’s match early in your career, then bump up your contribution amounts at the midpoint of your career, and max out your contributions as you draw closer to retirement, if you can.

Another option is follow a common guideline and save 10% of your income beginning as soon as you can swing it. From there, you can work up to saving the max. And remember, you don’t have to limit your savings to your 401(k). You may also be able to save in other retirement vehicles, like a traditional IRA or Roth IRA.

Of course, a main determination of the amount you need to save is what your goals are for the future. By contemplating what you want and need to spend money on now, and the quality of life you’d like when you’re older, you can make the decisions that are best for you.

FAQ

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

If you can, try to contribute at least enough of each paycheck to get your employer’s matching funds, if they offer a match. So if your employer matches 6% of your contributions, aim to contribute at least 6% of each paycheck.

What percent should I put in my 401(k)?

A common rule of thumb is to contribute at least 10% of your income to your 401(k) to help reach your retirement goals. Just keep in mind the annual 401(k) contribution limits so you don’t exceed them. For 2025, those limits are $23,500, plus an additional $7,500 for those 50 and up. In 2025, those aged 60 to 63 may contribute an additional $11,250 (instead of $7,500).

Is 10% too much to contribute to 401(k)? What about 20%?

Contributing at least 10% to your 401(k) is a common rule of thumb to help save for retirement. If you are able to contribute 20%, it can make sense to do so. Just be sure not to exceed the annual 401(k) contribution limits. The contribution limits may change each year, so be sure to check annually.
