When you're planning your 401(k) contributions, most financial pros would tell you that the first priority is to contribute at least enough to earn all of the matching dollars that your employer offers. Whether that match is small or large, it amounts to free money.

If your employer doesn’t offer a match (or if you’re deciding whether to contribute more than you need to get the match) and have no idea where to start, a general rule of thumb is to consider saving 10% to 15% of your income. However, this is just a guideline. You can put together a more detailed goal from a retirement calculator, or speak with a financial planner.

How much can you contribute to a 401(k)?

The most you can contribute to a 401(k) is $23,000 in 2024 ($30,500 for those age 50 or older). Employer contributions are on top of that limit. These limits are set by the IRS and subject to adjustment each year.

That limit dictates how much you can contribute, but it doesn’t tell you how much you should contribute. To figure that out, consider the following.

Think about how much you'll need in retirement

Contributing the maximum to your 401(k) requires a lot of money — especially as an ongoing, year-after-year commitment. It may or may not be enough to fund your retirement, or it could be even more than you need. Your 401(k) contribution amount should be guided by your retirement savings goal.

How much money you'll need in retirement depends on when you plan to retire, how much of your current income you’d like to replace and how much you want to rely on Social Security.

If you need to start at a lower contribution than the general 10% to 15% guideline and work your way up, that's fine. Aim to contribute at least enough of your paycheck to grab the employer match, then consider bumping up the percent you contribute by 1% or 2% each year.

An IRA might be a better option

If you are already contributing up to your employer match, another way to invest additional cash is through a traditional or Roth individual retirement account. (And if you have no employer match, start with the IRA.) The IRA contribution limit is much lower — $7,000 in 2024 ($8,000 if age 50 or older) — so if you max that out but want to continue saving, go back to your 401(k).

Some 401(k) plans, typically at large companies, have access to investments with very low expense ratios. That means you’ll pay less through your 401(k) than you might through an IRA for the very same investment. In other cases, the opposite is true; small companies generally can’t negotiate for low-fee funds the way large companies may be able to. And because 401(k) plans offer a small selection of investments, you’re limited to what's available.

Let’s be clear: While fees are a bummer, matching dollars from your employer outweigh any fee you might be charged. But once you’ve contributed enough to earn the full match — or if you’re in a plan with no match at all — the decision of whether to continue contributions to your 401(k) is all about those fees. If the fees are high, direct additional dollars over the match to a traditional or Roth IRA.

401(k), IRA, Roth: Know the tax impact

With a traditional 401(k), your contributions come out of your paycheck pretax, but distributions in retirement are taxed as income. That means your money grows tax-deferred.

With a Roth 401(k), your contributions are made after tax but distributions in retirement are tax-free — you never pay taxes on investment growth.

The difference between a Roth and traditional IRA is the same. If your employer doesn’t offer a Roth version of a 401(k), you may want to start contributing to a Roth IRA after you’ve achieved your 401(k) match, to build some of that tax-free income in retirement.

In general, money contributed to a Roth account is more valuable in retirement, because you’re not handing a portion of every distribution to the IRS.

If you max out that Roth IRA and need to continue saving, go back to the 401(k) and continue contributions there.
