How to Adjust Your 401(k) Contribution

Quick answer

• You can typically change your 401(k) contribution amount at any time through your employer’s HR portal or by contacting your plan administrator.
• Understand your current contribution rate and how it aligns with your financial goals.
• Before adjusting, assess your emergency fund, debt levels, and other savings priorities.
• Consider the impact of contribution changes on your take-home pay and potential tax benefits.
• Review your plan’s investment options and ensure they still meet your risk tolerance and time horizon.
• If unsure, consult your employer’s HR department or a qualified financial advisor.

What to check first (before you invest)

Time horizon

Your investment timeline is crucial. Are you saving for retirement decades away, or a shorter-term goal like a down payment in five years? A longer horizon generally allows for more aggressive investment choices, while a shorter one might call for a more conservative approach.

Risk tolerance

This refers to how comfortable you are with potential fluctuations in your investment value. Some people can stomach market downturns, while others lose sleep over even small dips. Your risk tolerance should guide your investment selections within your 401(k).

Emergency fund

Before significantly increasing your 401(k) contributions, ensure you have a robust emergency fund. This typically covers 3-6 months of essential living expenses, providing a safety net for unexpected events like job loss or medical emergencies without derailing your long-term investments.

Fees and tax impact

Understand the fees associated with your 401(k) plan, such as administrative or investment management fees. Also, consider the tax implications of your contributions. Traditional 401(k) contributions are pre-tax, lowering your current taxable income, while Roth 401(k) contributions are after-tax, offering tax-free withdrawals in retirement.

Account type

Your 401(k) is an employer-sponsored retirement savings plan. While this article focuses on adjusting contributions, remember that other retirement accounts like Individual Retirement Arrangements (IRAs) exist, each with different rules and contribution limits.

Step-by-step (simple workflow)

1. Determine your current contribution rate

What to do: Log in to your employer’s HR portal or contact your HR department to find out exactly what percentage of your salary you are currently contributing to your 401(k).
What “good” looks like: You have a clear understanding of your current contribution amount, whether it’s a percentage or a fixed dollar amount.
A common mistake and how to avoid it: Not knowing your current rate. Avoid this by taking a few minutes to look it up before making any changes.

2. Review your financial goals

What to do: Think about your short-term and long-term financial objectives. Are you on track for retirement? Do you have other pressing financial needs?
What “good” looks like: You have a clear picture of what you want your money to do for you, both now and in the future.
A common mistake and how to avoid it: Adjusting contributions based solely on a desire to save more without considering other financial priorities like debt repayment or emergency savings.

3. Assess your emergency fund status

What to do: Verify that you have an adequate emergency fund (3-6 months of living expenses) before significantly increasing contributions.
What “good” looks like: You have a readily accessible savings account with enough to cover unexpected expenses.
A common mistake and how to avoid it: Over-contributing to your 401(k) at the expense of building an emergency fund, forcing you to tap into investments prematurely if an emergency strikes.

4. Calculate the impact on your take-home pay

What to do: Use a take-home pay calculator or do some simple math to see how a change in contribution percentage will affect your net pay.
What “good” looks like: You understand precisely how much less or more you will receive in your paycheck after the adjustment.
A common mistake and how to avoid it: Not anticipating the reduction in take-home pay, leading to a cash flow crunch.

5. Understand your employer match

What to do: Check your plan documents or ask HR about your employer’s matching contribution policy.
What “good” looks like: You know if your employer offers a match and at what rate, ensuring you contribute enough to get the full benefit.
A common mistake and how to avoid it: Not contributing enough to receive the full employer match, essentially leaving “free money” on the table.

6. Access the contribution change portal/form

What to do: Find out how your employer allows you to make changes. This is usually an online portal or a paper form.
What “good” looks like: You have the correct system or form ready to submit your desired changes.
A common mistake and how to avoid it: Using an outdated or incorrect form, which can delay or invalidate your request.

7. Enter your desired contribution percentage or amount

What to do: Input your new contribution rate. Decide if you want to contribute a percentage of your salary or a fixed dollar amount.
What “good” looks like: You have confidently entered your new contribution, aiming to maximize benefits while remaining comfortable.
A common mistake and how to avoid it: Entering an amount that is too high and will strain your budget, or too low and misses opportunities.

8. Confirm and submit your changes

What to do: Carefully review all the details of your requested change before submitting.
What “good” looks like: You have double-checked your new contribution rate and confirmed all other details are correct.
A common mistake and how to avoid it: Submitting the change without a final review, which could lead to errors.

9. Note the effective date

What to do: Find out when your new contribution rate will take effect. It’s often the next pay period, but not always.
What “good” looks like: You know exactly when the change will be reflected in your paychecks and 401(k) contributions.
A common mistake and how to avoid it: Assuming the change is immediate and budgeting based on that assumption, only to find your paycheck is higher than expected for a pay period.

10. Monitor your paychecks and statements

What to do: For the next few pay periods, verify that your contributions are being deducted correctly and that your 401(k) statements reflect the new contribution amount.
What “good” looks like: Your payroll deductions and account statements accurately show your updated contribution.
A common mistake and how to avoid it: Failing to monitor, which could mean an error goes unnoticed for an extended period.

Risk and diversification (plain language)

• Diversification is like not putting all your eggs in one basket. If one investment performs poorly, others might do well, balancing out your overall returns. For example, instead of investing only in tech stocks, you might also invest in bonds or real estate funds.
• Asset allocation is how you divide your money among different types of investments. This is a key part of diversification. A common mix for retirement might be stocks (for growth) and bonds (for stability).
• Stocks represent ownership in companies. They offer the potential for higher growth but also come with higher risk. Think of buying a small piece of Apple or a local business.
• Bonds are like loans you make to governments or corporations. They are generally considered less risky than stocks and provide regular income, but their growth potential is usually lower.
• Mutual funds and Exchange-Traded Funds (ETFs) are baskets of many different investments. They offer instant diversification because they hold many stocks or bonds within a single fund.
• Your time horizon influences your risk. If you’re young and decades from retirement, you can generally afford to take on more risk with stocks, as you have time to recover from market downturns.
• As you get closer to retirement, you might shift towards more conservative investments. This means increasing your allocation to bonds and reducing your exposure to volatile stocks to protect your savings.
• Rebalancing is periodically adjusting your portfolio to maintain your desired asset allocation. If stocks have grown significantly, you might sell some and buy more bonds to get back to your target mix.

During market drops, it’s natural to feel anxious. The best approach is often to stay calm and stick to your long-term plan. Avoid making impulsive decisions to sell everything. Remember that market downturns are a normal part of investing, and historically, markets have recovered over time. If your plan allows, consider increasing your contributions during a downturn, as you’ll be buying investments at lower prices.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not contributing enough to get the full match	Losing out on “free money” from your employer, significantly reducing your potential retirement nest egg.	Contribute at least enough to receive the maximum employer match offered by your plan.
Ignoring fees	Higher fees erode your investment returns over time, leaving you with less money in retirement.	Review your plan’s fee structure and choose low-cost investment options when available.
Not having an emergency fund	Needing to withdraw from your 401(k) early due to an emergency, incurring penalties and taxes.	Prioritize building and maintaining an emergency fund of 3-6 months of living expenses before making aggressive retirement contributions.
Increasing contributions too much too soon	Creating a cash flow problem that forces you to cut back on essential expenses or even miss other financial goals.	Gradually increase your contribution rate, ensuring your take-home pay remains sufficient for your needs.
Not understanding your investment options	Choosing investments that don’t align with your risk tolerance or time horizon, leading to suboptimal returns.	Educate yourself on the available investment choices and consult plan materials or a financial advisor.
Making emotional investment decisions	Selling during market downturns and buying during market peaks, leading to significant losses.	Stick to a predetermined investment strategy and rebalance periodically rather than reacting to market noise.
Forgetting to update beneficiaries	Your assets may not go to your intended heirs upon your passing, causing legal complications.	Review and update your beneficiary designations regularly, especially after major life events.
Not increasing contributions with raises	Missing opportunities to boost retirement savings as your income grows, slowing down wealth accumulation.	Commit to increasing your contribution rate by at least 1% each time you receive a salary increase.
Contributing only to the company stock	Extreme lack of diversification, making your entire retirement savings vulnerable to the performance of one company.	Diversify your 401(k) holdings across various asset classes and investment funds, not just company stock.

Decision rules (simple if/then)

• If your employer offers a match, then contribute at least enough to get the full match, because it’s essentially free money that boosts your savings.
• If you don’t have 3-6 months of living expenses saved, then prioritize building your emergency fund before significantly increasing 401(k) contributions, because unexpected expenses can force costly withdrawals.
• If your time horizon to retirement is 20+ years, then consider a higher allocation to stocks, because you have more time to recover from market volatility and potentially achieve higher growth.
• If you are within 5-10 years of retirement, then consider shifting towards more conservative investments like bonds, because you want to protect your accumulated savings from significant market downturns.
• If your take-home pay will be too low to cover essential bills after an increase, then reduce the contribution percentage, because maintaining your current lifestyle and financial obligations is paramount.
• If you receive a salary increase, then consider increasing your 401(k) contribution by 1-2%, because your increased income can absorb the change without impacting your current spending level.
• If your plan has high expense ratios on its investment options, then explore lower-cost alternatives within the plan or consider whether an IRA might be more cost-effective for additional savings, because high fees significantly drag down long-term returns.
• If you are contributing to a traditional 401(k) and your tax bracket is expected to be lower in retirement, then continue with pre-tax contributions, because you are getting a tax deduction now when it’s more valuable.
• If you are contributing to a traditional 401(k) and your tax bracket is expected to be higher in retirement, then consider a Roth 401(k) if available, because paying taxes now when your bracket is lower may be more advantageous.
• If you are unsure about your investment choices, then consult your plan’s investment guide or a financial advisor, because making informed choices is crucial for long-term success.

FAQ

Q: How often can I change my 401(k) contribution?

A: Most employers allow you to change your contribution amount at any time, or at least with each pay period. Some may have specific windows, so check with your HR department.

Q: What is the maximum I can contribute to my 401(k)?

A: The IRS sets annual limits for employee contributions to 401(k) plans. These limits can change each year. Check with your HR department or the IRS for the current year’s maximum.

Q: Will changing my contribution affect my taxes?

A: Yes, if you contribute to a traditional 401(k), increasing your contribution will lower your taxable income for the current year. Decreasing it will have the opposite effect. Roth 401(k) contributions do not affect your current taxable income.

Q: What happens if I stop contributing to my 401(k)?

A: You will miss out on potential investment growth and any employer match. If you stop contributing, your employer’s match will also likely cease.

Q: Should I contribute to a traditional 401(k) or a Roth 401(k)?

A: It depends on your current and expected future tax bracket. Traditional is better if you expect to be in a lower tax bracket in retirement; Roth is better if you expect to be in a higher bracket.

Q: How do I know if I’m contributing enough?

A: A good starting point is to contribute enough to get your full employer match. Beyond that, aim for a percentage that aligns with your retirement savings goals, often between 10-15% or more of your income, including the match.

Q: Can I change my investment allocations when I change my contribution?

A: Yes, you can typically change your investment allocations separately from your contribution percentage, often through the same online portal or by contacting your plan administrator.

Q: What is an employer match?

A: An employer match is when your employer contributes a certain amount to your 401(k) based on your own contributions. For example, they might match 50% of your contributions up to 6% of your salary.
