How Much to Contribute to Your 401(k) Each Year

Start with what your employer will match, then increase from there

The amount you should contribute depends on three things: what your employer will match, what you can afford to live on after the contribution, and how much you want saved by retirement. Most people should start by contributing enough to capture the full employer match—that is assistance programs you forfeit if you don't take it. After that, contribute as much as your budget allows, up to the annual limit set by the IRS.

The IRS limit for 2024 is $23,500 if you are under 50, and $30,500 if you are 50 or older (the extra $7,000 is called a catch-up contribution). Your employer's match is separate from this limit and does not count against it. If your employer matches 3 percent of your salary and you earn $60,000, that match is worth $1,800 per year—money that goes into your account without you having to earn it through investment returns.

Key Takeaways

• Contribute at least enough to get your full employer match, because passing it up means leaving money on the table permanently.
• The IRS contribution limit is $23,500 per year for people under 50 and $30,500 for people 50 and older, and these limits change each year.
• Your take-home pay will drop by less than your contribution amount because contributions reduce your taxable income, lowering your tax bill.
• If you cannot afford the full match right now, increase your contribution by 1 percent each year until you reach it.
• Catch-up contributions at age 50 let you save an extra $7,000 per year if you have not saved enough earlier.

How employer matching works and why you should not leave it unclaimed

An employer match is a promise to add money to your 401(k) based on what you contribute. The most common match is 100 percent of the first 3 percent you contribute, meaning if you put in 3 percent of your salary, your employer adds another 3 percent. Some employers match 50 percent of the first 6 percent, or other combinations. Your employee handbook or benefits summary should state your plan's exact match formula.

If you contribute less than the amount needed to get the full match, you lose the unmatched portion forever. For example, if your employer matches 100 percent of the first 3 percent and you only contribute 2 percent, you get a 2 percent match but miss out on the 1 percent your employer would have added. That 1 percent does not roll over to next year—it simply disappears. Over a 30-year career, leaving a 1 percent match unclaimed can cost you tens of thousands of dollars in lost contributions and investment growth.

Calculating what you can actually afford to contribute

Your contribution comes out of your paycheck before taxes, so your take-home pay drops by less than the contribution amount. If you contribute $500 per month and you are in the 22 percent federal tax bracket, your take-home pay drops by only about $390 because you save roughly $110 in taxes that month. This tax savings makes contributing more affordable than it appears.

To find what you can afford, look at your recent pay stubs and add up your monthly expenses: rent or mortgage, utilities, food, transportation, insurance, debt payments, and anything else you spend money on regularly. Subtract that total from your after-tax income. The difference is what you have left to split between savings, discretionary spending, and 401(k) contributions. If the gap is tight, start with the employer match and increase your contribution by 1 percent each year as your salary grows or expenses shrink.

The IRS contribution limit and how it affects your strategy

The IRS sets an annual limit on how much you can contribute to your 401(k) from your own paycheck. For 2024, that limit is $23,500 if you are under 50. This limit applies only to your contributions, not to your employer's match or any investment gains in the account. If you earn $100,000 and contribute the full $23,500, your employer's match is added on top of that and does not count toward the limit.

The limit increases most years to keep pace with inflation. In 2023 it was $22,500, and in 2022 it was $20,500. Your payroll department will tell you the current year's limit, and the IRS publishes it each October for the following year. If you are contributing through payroll deduction, your employer will stop taking contributions once you hit the limit, so you do not have to track it yourself—but you should know the number so you can plan how much to contribute each pay period.

Catch-up contributions if you are 50 or older

At age 50, the IRS allows you to contribute an additional $7,000 per year beyond the standard limit. This is called a catch-up contribution and is meant to help people who did not save as much earlier in their careers. If you are 50 or older, your total contribution limit for 2024 is $30,500. Like the standard limit, this catch-up amount increases most years.

You do not have to do anything special to use catch-up contributions—your payroll department will know you are may be able to access once you turn 50. If you want to contribute the full $30,500, tell your benefits administrator or update your contribution rate in your 401(k) plan's website or app. Catch-up contributions are especially useful if you are behind on retirement savings and want to accelerate how much you set aside in your final working years.

Balancing 401(k) contributions with other financial goals

Saving for retirement is important, but it is not the only financial goal that matters. If you have high-interest debt like credit card balances, paying those down may give you a better return than investing in your 401(k), because credit card interest rates often exceed what you can earn in the market. Similarly, if you do not have an emergency fund with three to six months of expenses, building that should come before maxing out your 401(k).

A practical approach is to contribute enough to get your full employer match first, then use any extra money to pay down high-interest debt or build an emergency fund. Once those are in place, increase your 401(k) contribution. This order does not mean you ignore retirement—the employer match is still going into your account—but it protects you from financial emergencies that could force you to withdraw from your 401(k) early and pay penalties.

How to adjust your contribution over time

You do not have to decide on a single contribution rate and stick with it forever. Most plans let you change your contribution amount whenever you want, though some require changes to take effect on the first day of the next pay period. If you get a raise, consider putting half of the increase toward your 401(k) and keeping the other half as additional take-home pay. This way you save more without feeling like your paycheck shrank.

Many plans also offer automatic escalation, where your contribution rate increases by 1 percent each year on a date you choose—usually your birthday or the anniversary of your hire date. Automatic escalation is a powerful tool because it removes the need to remember to increase your contribution, and most people do not notice the small annual paycheck decrease. If your plan offers this feature, turning it on is one of the easiest ways to gradually reach a higher savings rate.

Frequently Asked Questions

What happens to my employer match if I leave my job?

Employer contributions vest according to your plan's vesting schedule, which your benefits summary should explain. Vesting means the money becomes yours to keep. Some plans vest immediately, while others require you to work there for two to five years before the match is fully yours. Once vested, the match stays in your account even after you leave. Unvested match is forfeited and goes back to the employer.

Can I contribute to both a 401(k) and an IRA in the same year?

Yes, you can contribute to both. The $23,500 limit applies only to your 401(k). You can also contribute up to $7,000 per year to a traditional or Roth IRA (or a combination of both), as long as you have earned income. However, if you earn above certain income thresholds and have access to a 401(k), your ability to deduct traditional IRA contributions may be limited. A tax professional can help you understand your specific situation.

Should I contribute more if I think the market will go up?

No. Trying to time the market by contributing more when you think stocks will rise is risky and usually backfires. Instead, contribute a steady amount every pay period regardless of market conditions. This approach, called dollar-cost averaging, means you buy more shares when prices are low and fewer when they are high, which tends to smooth out market swings over time.

What if my employer does not offer a match?

If your employer does not match, you should still contribute what you can afford, because the tax savings and long-term growth still matter. Without a match, there is no "assistance programs" to chase, so contribute based on your retirement goals and budget rather than trying to hit a specific percentage. Even small contributions add up over decades.

Can I change my contribution rate mid-year?

Yes. Most plans let you change your contribution rate at any time, though the change typically takes effect on the next pay period or the first day of the next month. If you get a bonus, inheritance, or unexpected income, you can increase your contribution to capture that money. If you face a financial hardship, you can decrease it temporarily. Contact your benefits administrator or log into your plan's website to make changes.
