Max Out Your 401(k): 8 Little-Known Ways to Boost Your Savings

Saving money in your company’s retirement plan is one of the easiest ways to invest in your future. The money automatically comes out of your paycheck and is invested on a regular basis. 

Some people even have the perk of a company match that can help them max out a 401(k)'s potential. But did you know there are also some 401(k) hacks that can boost your retirement savings even more by helping you learn how to invest money wisely?

Follow along to learn some of the little-known ways you can hack your personal finances, earn higher returns by making some savvy money moves, and reach your retirement goals quicker.

Pick your funds wisely

Company retirement plans typically offer a handful of mutual funds and other investments to choose from. When you first sign up for your company's 401(k) retirement plan, if you don't make a choice, your money will be invested in a default option. Depending upon your company's policies, this usually means a money market, stable value, or target-date fund.

So what’s the 401(k) hack? To reach your retirement goals, you'll want to personalize where your 401(k) contributions are being invested. Factors to think about include your tolerance for risk, time frame for retirement, and the available investment options.

As you reviewing your investment choices, think about these details:

• Look at the expense ratio of each fund. The expense ratio is how much the fund manager charges to manage that investment. The lower this number is, the better. Funds that track an index typically charge less than funds with a manager who manually researches and selects stocks.
• Avoid focusing on past returns. Historical returns show how an investment has performed over time. These returns may factor into your decision, but remember they do not guarantee future performance.
• What does it invest in? Don't pick multiple investments that invest in the same stocks and bonds. Instead, pick a diverse portfolio with different types of stocks and bonds from both the U.S. and foreign countries.

If your company's retirement plan is filled with investment choices that have high expense ratios, speak with your human resources department or manager. Request that they review the plan and consider finding a new plan sponsor. You may even share some low-cost index fund alternatives like Vanguard or Fidelity for them to consider.

Roll over 401(k)s from previous jobs

As you change jobs throughout your career, you may be leaving something valuable behind with each move — your old 401(k) account at your old job. It makes sense to move this money as quickly as possible so a few things don't happen:

• The old employer cashes out the 401(k) account and mails you a check or moves the money to an IRA of its choosing (if less than $5,000)
• The money is forgotten about and transferred to the state
• Your heirs never know about the money
• The money is not factored into progress toward your retirement goals

When you leave a job, you have several options for what you can do with your old 401(k):

• Roll over the 401(k) into an IRA. Doing a 401(k) to IRA rollover is a popular choice because you have more control over which company you choose to work with and your investment options.
• Transfer the 401(k) into your new employer's plan. Transferring into your new 401(k) makes your savings easier to monitor because all your funds are in one account. Company retirement plans also offer more protection from creditors than IRAs.
• Leave it in your old company's plan. Some companies do not allow low-balance accounts to remain in their plans, and they may either issue you a check or roll over the funds into an IRA of their choosing, so this may not be an option.
• Cash out the balance. This can have devastating impacts on your retirement savings because you'll lose out on the opportunity to earn tax-deferred gains between now and your retirement age. You'll also pay taxes on the money plus a 10% early withdrawal penalty.

When transferring to your new 401(k) or rolling over to an IRA, it is best to have your old 401(k) send the money directly to your new retirement account. If the money is sent to you, it could trigger taxes and penalties depending on how the check is written and how long you hold onto the money.

Sign up for auto-escalation

A lot of people don't make enough money to max out their retirement accounts when they first start investing. Instead, they start out with a small retirement plan contribution. They mean to increase it, but often forget as work and personal life responsibilities take center stage.

An easy hack is to increase your 401(k) contribution every year when you get your raise. You won't miss this extra money because it was never in your paycheck to begin with. Over the course of several years, you'll get closer to maxing out your retirement account while putting away larger and larger amounts of money for your future.

For example, if you get a 3% raise, consider increasing your 401(k) contribution by 1% or 2%. Because so many other bills don't increase every year, like your mortgage or auto payment, investing a portion of your raise is easier to do.

One way to automate this process is to sign up for the auto-escalation of retirement contributions. Not all 401(k) plans offer this, so check with your HR department or manager to find out. Auto-escalation increases your retirement plan contributions automatically so you don't have to remember.

If your company does not offer auto-escalation, set a calendar reminder for your pay raise date so you can manually make the change.

Rebalance your portfolio

Investment returns vary from year to year for each type of investment. When you have a mix of investments in your account, this can change the composition of your portfolio from what you intended. 

But you chose the composition of your portfolio because it would help you best reach your financial goals. So to bring your account back into alignment, you should do what’s known as a rebalance every so often.

When you rebalance, you sell some of the investments that went up in value, while buying more of those that went down. Here’s what it looks like when a portfolio goes out of alignment and then how a rebalance can fix things:

Two popular strategies to consider when rebalancing:

• Rebalance once a year (e.g., on your birthday)
• Rebalance when an asset's allocation changes by more than 5% (e.g., from 50% to 55% of your total account balance)

Pick one of these strategies and make the rebalancing hack a regular part of your 401(k) maintenance.

Make after-tax contributions

Current Internal Revenue Service rules for 2024 allow for people under 50 years old to contribute $23,000 per year to their 401(k) plan. People 50 and over can contribute another $7,500 in 2024, for a total of $30,500.

If you can save more than these amounts, consider fully funding an IRA account. You can choose a traditional IRA for the tax deduction or a Roth IRA for tax-free money in retirement. The 2024 maximum contribution allowed by the IRS to an IRA is $7,000 per year (plus $1,000 if over age 50).

But what about those who are unable to contribute fully to an IRA or who want to invest even more money?

It is possible to contribute even more money to your 401(k) plan as after-tax contributions, even if you have a traditional 401(k) vs. a Roth 401(k). The combined 401(k) contribution limit for 2024 is $69,000.

To calculate your after-tax contribution, subtract these amounts from the $69,000 limit:

• Your total 401(k) contributions from your paycheck (maximum of $23,000 or $30,500 for investors aged 50 or over in 2024)
• Your total employer match amount

The amount remaining is the maximum after-tax contribution that you can make. This is a maximum, so you can always contribute less.

After-tax contributions can be withdrawn at any time without paying taxes or penalties. However, any earnings are considered pre-tax balances, so there are taxes owed on withdrawals of earnings. 

You must withdraw earnings when withdrawing after-tax contributions, so there will be some taxes owed on withdrawals. Consider this when you do your tax planning for your retirement years.

Your after-tax contributions can also be converted into a Roth IRA. This allows your after-tax contributions to grow tax-deferred and withdrawals to be tax-free. You may have to wait until after you leave your job to do this because not all companies allow in-service 401(k) conversions.

Open a solo 401(k)

For investors with a side hustle, opening a solo 401(k) is a great hack, especially if you don't have a company retirement plan at your day job. These accounts allow the self-employed and small business owners with no employees to set aside a portion of their business profits. 

If you are under 50 years old, you can contribute up to $23,000 from your salary, plus the company can contribute up to 25% of your compensation.

For example, if you are under 50 years old and earn $50,000 in wages from your business, you can contribute $23,000, and the company can contribute another $12,500. This results in a total solo 401(k) contribution of $35,500 for the year. If you are older than 50, you are allowed an additional catch-up contribution of up to $7,500.

You can set up a solo 401(k) at investment firms like Vanguard and Fidelity, and if you have a 401(k) from your employer, you can still have a solo 401(k). There are contribution limits on a solo 401(k), and the contributions from both your employer’s plan and your solo plan will count toward your annual maximum.

Use the Rule of 55

Reaching the age of 65 is usually the target for retirement. However, the FIRE lifestyle movement (financial independence, retire early) is gaining in popularity, and many now aspire to achieve early retirement. 

Usually, retirees are required to wait until they reach 59 1/2 before they can start to withdraw from retirement accounts and avoid penalties. However, there is a hack to access your 401(k) retirement account early without incurring a penalty. It is based on Internal Revenue Code and is known as the Rule of 55.

The Rule of 55 allows workers who leave their job during the year they turn 55 years of age or older to withdraw money from their 401(k) accounts without a penalty. 

No matter the reason for leaving your job — if you quit, got fired, or were laid off — as long as you meet the age requirement, you are good. 

Even better, people who are qualified safety employees for the federal, state, or local government may start making penalty-free withdrawals at age 50.

Keep in mind that the Rule of 55 doesn't apply to all retirement accounts. It applies only to the 401(k) at the employer you are leaving. For this reason, it may make sense to roll over your old 401(k) accounts into your current employer account in order to have more funds available.

Although you can take advantage of the Rule of 55, it may not make sense to. With the average life expectancy being almost 79 years in the U.S., you should allow your tax-deferred retirement accounts to grow for as long as possible. 

You may want to withdraw money from your taxable brokerage account or have other income sources, such as real estate investments, to pay your bills while waiting for the traditional retirement age.

Consult your advisor

When people think about financial advisors, they usually think about their IRAs and brokerage accounts. Financial advisors typically don't manage your 401(k), but they can still provide advice on investment selection. This advice could help you avoid costly retirement mistakes.

If you think about it, a good financial planner should want to help you with your company retirement plan, even if they aren't getting paid for it. The bigger those assets grow, the larger the investment opportunity will be when you leave your job or retire.

Bonus tip: What to do after you max out

Just because you’ve maxed out your 401(k), it doesn’t mean that your financial planning has to end or that you can’t keep investing. Here are some ways to continue maximizing your money:

• Open an IRA. An individual retirement account can provide you with a way to continue receiving tax benefits for your money. The amount of your potential deduction might be subject to an income limit or limited by the presence of a 401(k), but you might still receive some benefit from making IRA contributions.
• Use a Roth IRA. If you meet the requirements to open a Roth IRA, this can be a way to diversify your tax profile in retirement. Although you make contributions with after-tax dollars, the money will grow tax-free, and you also won’t be subject to required minimum distributions later.
• Consider a health savings account. If you have a high-deductible health plan, you may be eligible for an HSA, which can be a good way to get triple tax benefits and save up for future healthcare expenses. With an HSA, you get a tax deduction for your contributions, you can invest your balance, and withdrawals are tax-free as long as they’re used for qualified medical expenses. Later, when you reach age 65, your HSA can act as a backup retirement account. You pay taxes on non-qualified withdrawals, but you can avoid the 10% penalty.
• Invest in a taxable account. Finally, if you want to grow your wealth but don’t want the restrictions that come with tax-advantaged accounts, you can consider opening a taxable investment account. You’re responsible for capital gains when you sell assets, but the money is fairly liquid, and you don’t have to worry about early withdrawal penalties.
