401k Confusion Abounds and How to Clear It Up

The 401k - a staple of retirement savings for many Americans, but also a source of confusion for just as many. The truth is, there's a lot to figure out, from contribution limits to investment options.

One of the biggest sources of confusion is the difference between a traditional 401k and a Roth 401k. A traditional 401k allows you to contribute pre-tax dollars, which reduces your taxable income for the year, but you'll pay taxes on withdrawals in retirement. On the other hand, a Roth 401k allows you to contribute after-tax dollars, which means you've already paid taxes on the money, but you won't have to pay taxes on withdrawals in retirement.

Many people are also unsure about how much to contribute to their 401k. The good news is that you can contribute up to $19,500 in 2022, and an additional $6,500 if you're 50 or older.

A different take: 401k Confusion

One common misconception is that 401(k) plans are only for big companies, but the truth is that even small businesses can offer them.

Many people believe they can withdraw from their 401(k) plan penalty-free, but the reality is that withdrawals before age 59 1/2 come with a 10% penalty.

It's often assumed that 401(k) plans are a one-size-fits-all solution, but in reality, there are different types of plans, including traditional, Roth, and safe harbor plans.

Some individuals think they can contribute to a 401(k) plan without affecting their Social Security benefits, but contributions do count towards the income limit for Social Security benefits.

The idea that 401(k) plans are only for retirement savings is a misconception, as some plans allow for loans or emergency withdrawals.

A common misconception is that 401(k) plans are completely portable, but in reality, there may be fees or penalties for transferring funds to a new employer's plan.

Employers can inadvertently contribute to 401(k) plan failures by not automatically enrolling employees. This can lead to a low participation rate, such as 67% in voluntary plans.

The SECURE Act 2.0, passed in 2022, mandates that most new 401(k) plans must automatically enroll employees starting in 2025. This is a step in the right direction.

A low default enrollment percentage, often 3% of salary per year, can also contribute to 401(k) plan failures. This may not be enough for workers who got a late start on retirement savings.

Job changes can compound the problem, causing a dip in savings rate. For example, a worker who changes jobs eight times, for a total of nine jobs, could lose about $300,000 by sticking with the auto-enrollment percentage rather than selecting a 401(k) deferral percentage based on their income and retirement goals.

Failing to adjust 401(k) contributions after a pay raise can also lead to 401(k) plan failures. It's essential to set aside the extra money upfront, rather than waiting to see what's left at the end of the month.

Not taking advantage of a 401(k) match or increasing deferrals to make up for a reduced match can also hinder 401(k) plan success. For instance, if an employer offers a 3% match and the employee contributes 10%, they could increase their deferral rate to 13% to maintain the same percentage of their income in the 401(k).

Many workers are confused about their 401(k) participation, with some believing they're saving when they're not.

Roughly half of nonsavers thought they had been automatically enrolled in a 401(k), and two-fifths thought they had signed themselves up.

Automatic enrollment can be a game-changer, with Vanguard finding that workers with auto-enrollment 401(k) plans participated at a rate of 94% in 2023.

Employers can clear up the confusion by automatically enrolling employees, leaving it to the worker to opt out, which is now required for most new 401(k) plans starting in 2025.

Clear communication is key, with experts suggesting that employers should tell employees whether they are participating and how much they are contributing.

Companies with 401(k) plans should send personalized messages to employees, reminding them if they are enrolled and encouraging them to save 10% or more of their income.

If you're unsure about whether or not you're contributing for retirement, double-check with your employer.

Auto-enrollment can be a convenient feature, but it often starts at a low rate of 3% of your salary per year, according to Vanguard.

You should aim to contribute at least as much to your new 401(k) as you were to your old one, especially if you've had a pay raise.

The default enrollment percentage can be a problem, especially if you change jobs frequently, which can lead to a dip in your savings rate.

If you've been auto-enrolled at 10% of your salary and then change jobs to one that auto-enrolls you at 3%, you could lose a significant amount of money over time, potentially up to $300,000.

Before leaving your old job, take note of your current 401(k) contribution rate and aim to contribute at least that much to your new one.

You should also consider increasing your deferrals if your new employer doesn't offer a match or offers a smaller one, to make up for the difference.

If you're not careful, the 401(k) plan can be a real trap, eating away at your savings before you even know it.

Not contributing enough to your 401(k) can be a costly mistake, especially if you're not keeping up with your previous employer's match. For example, if you used to contribute 10% of your income and your old employer contributed 3%, but your new employer offers nothing, you may need to increase your deferral rate to 13% to make up for the lost match.

Lifestyle creep can also sabotage your 401(k) progress, as you may find yourself spending extra cash on luxuries rather than saving it for retirement. This is why it's essential to set aside extra money upfront, rather than waiting to see what you have left at the end of the month.

Exceeding the annual contribution limits can lead to steep tax penalties, so be sure to check the limits regularly. In 2025, adults under 50 can set aside up to $23,500, while those 50 to 59 and 64 or older can save up to $31,000.
