What is a 401(k) Plan?
A 401(k) is a retirement savings plan that helps you save and is helpful in terms of taxes. Employers give this plan to their workers. It is named after a part of the tax code that created it. These plans let employees put some of their salary into savings for retirement.
There are two main types of 401(k) plans:
- Traditional 401(k): You put in money before taxes. This lowers how much tax you pay now. You will pay taxes when you take money out in retirement.
- Roth 401(k): You put in money after paying taxes. This does not lower your current taxes. However, when you withdraw money during retirement, it is tax-free.
How Our 401(k) Calculator Works
Our calculator helps you figure out how your 401(k) investments could increase over time. It considers several important factors.
- Current and Retirement Age: This affects how long you can invest.
- Current Salary: This is what you use to find out how much you can put in.
- Current 401(k) Balance: The amount you have saved for retirement so far.
- Contribution Percentage: The percentage of your salary that you set aside for your 401(k).
- Employer Match: Many companies add a certain percentage to what you put in, but only up to a point.
- Expected Annual Return: How much your investments might grow each year.
- Annual Salary Increase: This is how much you expect your salary to go up each year.
Key Benefits of a 401(k) Plan
- Tax Advantages: Traditional 401(k) lowers your taxable income now. A Roth 401(k) lets you take out money tax-free when you retire.
- Employer Matching: A lot of employers will match some of your contributions. This is basically free money for your retirement
- Easy Deductions: Your contributions automatically come out of your paycheck. This makes saving easy and regular.
- Higher Limits For Contribution: A 401(k) plan allows you to save more each year than an IRA.
- Growth Without Taxes: Your investments can grow without taxes until you take them out (or tax-free with a Roth), which can help your savings grow faster.
- Moving It: If you switch jobs, you can usually transfer your 401(k) to your new employer's plan or an IRA.
401(k) Contribution Limits for 2025
The IRS decides the yearly limits on how much you can put into your 401(k). For 2025, the limits are:
- Employee Contribution Limit: $23,500 for participants under age 50
- Catch-up Contribution: An additional $7,500 for participants age 50 or older
- Total Contribution Limit: The total annual additions to your 401(k) account (including your contributions, employer match, and any other employer contributions) cannot exceed $66,000 ($73,500 for those 50 or older)
These limits are changed from time to time because of inflation.
Employer Matching Strategies
Employer matching is one of the most valuable benefits of a 401(k) plan. Many matching methods include:
- Full Match up to a Percentage: The company matches your contributions fully, up to a certain part of your salary. For example, they give 100% match on the first 3% you contribute.
- Partial Match up to a Percentage: The company matches part of your contributions, also based on a percentage of your salary. For instance, they may give a 50% match on the first 6% you put in.
- Tiered Match: There are different matching rates for different contribution amounts. For example, you might get 100% on the first 3%, and then 50% on the next 2%.
To make the most of your retirement savings, try to put in enough money to get your full company match. This is like free money!
Investment Strategies for 401(k) Plans
Most 401(k) plans give several choices for investments. Here are some common strategies:
- Target-Date Funds: These funds automatically change their mix of assets to become safer as you get closer to retirement.
- Asset Allocation Based on Age: A common idea is to take your age from 110 or 120, and use that number to decide how much to invest in stocks, putting the rest in bonds.
- Three-Fund Portfolio: A simple plan that uses a U.S. total stock market index fund, an international stock index fund, and a bond index fund.
- Risk-Based Portfolio: A way to allocate your investments based on how much risk you can handle instead of your age. This might work better for some investors.
No matter your plan, it is important to rebalance often. This helps keep your asset mix as you want it, since different investments do not always act the same over time.
Early 401K Withdrawal Considerations
While 401(k) plans are made for retirement, there are times when you may need to get the money before then.
- Early Withdrawal Penalties: If you take money out before age 59½, you usually have to pay a 10% penalty along with income taxes.
- Hardship Withdrawals: Some plans let you take money out for urgent and serious needs. However, these still have taxes and possible penalties.
- Loans: A lot of plans let you borrow from your 401(k). You can borrow up to 50% of your balance or $50,000, whichever is less. You must pay this back with interest.
- Rule of 55: If you leave your job in or after the year you turn 55, you may take money out from your 401(k) without a penalty.
- Substantially Equal Periodic Payments (SEPP): Taking a set amount of money out over time can help you avoid the early withdrawal penalty, but it can be a bit tricky.
It is usually better to save your retirement money for retirement. You should consider other choices first before taking out money early.
Required Minimum Distributions (RMDs)
Once you reach age 73 (as of 2025), you generally must start taking required minimum distributions (RMDs) from your traditional 401(k) accounts. This age will increase to 75 by 2026.
These RMDs are based on your account balance and how long you might live. If you don’t take RMDs, you could face a big tax penalty. This penalty is 25% of the amount you didn’t take out. However, it can be lowered to 10% if you fix it quickly.
Roth 401(k) accounts have Required Minimum Distributions (RMDs), but Roth IRAs do not. You can skip RMDs on Roth 401(k) money by transferring it to a Roth IRA.
Maximizing Your 401(k) Benefits
- Start Early: The power of earning interest means small amounts can grow a lot over time.
- Get the Full Match: Put in enough money to receive your full match from the company.
- Increase Contributions Gradually: Think about raising your contribution percent each time you receive a raise.
- Watch Fees: High fees can lower your returns over time.
- Diversify: Spread your investments across different areas to lower risk.
- Review Regularly: Look over your investment choices and how your money is spread out at least every year.
- Consider Tax Diversification: Having both traditional and Roth accounts gives you more flexibility in retirement.
Frequently Asked Questions
A 401(k) is an employer-sponsored retirement savings plan that allows employees to contribute a portion of their salary on a pre-tax basis (traditional 401(k)) or an after-tax basis (Roth 401(k)). These plans are named after the section of the U.S. Internal Revenue Code that established them.
The key benefit of a 401(k) plan is that it allows your investments to grow either tax-deferred (traditional) or tax-free (Roth), potentially leading to significant savings over time due to compound growth.
At minimum, you should aim to contribute enough to receive your full employer match, if one is offered. This is essentially "free money" and an immediate return on your investment.
Beyond that, financial experts often recommend saving at least 15% of your pre-tax income for retirement, including your employer match. However, the right amount depends on your age, current savings, retirement goals, and overall financial situation.
If possible, working toward contributing the maximum allowed by the IRS (which is $23,500 for 2025, plus an additional $7,500 if you're 50 or older) will put you in a strong position for retirement.
The main differences relate to taxation:
- Traditional 401(k): Contributions are made with pre-tax dollars, reducing your current taxable income. You'll pay taxes on withdrawals during retirement.
- Roth 401(k): Contributions are made with after-tax dollars, so they don't reduce your current taxable income. However, qualified withdrawals during retirement are tax-free, including any investment gains.
A traditional 401(k) might be better if you expect to be in a lower tax bracket during retirement, while a Roth 401(k) might be preferable if you expect to be in the same or higher tax bracket in retirement.
Employer matching is when your employer contributes to your 401(k) based on your own contributions. Common matching formulas include:
- Dollar-for-dollar match up to a percentage: For example, they might match 100% of your contributions up to 3% of your salary.
- Partial match up to a percentage: For example, they might match 50% of your contributions up to 6% of your salary.
Employer matching contributions typically vest over time, meaning you need to stay with the employer for a certain period to fully own these contributions.
When you change jobs, you have several options for your 401(k):
- Leave it with your previous employer (if the plan allows and your balance is over $5,000)
- Roll it over to your new employer's plan (if the new plan accepts rollovers)
- Roll it over to an IRA (Individual Retirement Account)
- Cash it out (generally not recommended due to taxes and penalties)
The best option depends on factors like investment options, fees, loan provisions, and RMD rules in each plan. In many cases, rolling over to an IRA or your new employer's plan allows you to keep your retirement savings consolidated and growing tax-advantaged.
Yes, but early withdrawals (before age 59½) typically come with significant costs:
- A 10% early withdrawal penalty (with some exceptions)
- Income taxes on the withdrawn amount (for traditional 401(k)s)
- Loss of potential tax-advantaged growth
Some plans allow for hardship withdrawals in cases of immediate and heavy financial need, though these are still generally subject to taxes and potentially penalties.
Many 401(k) plans also allow loans, which must be repaid with interest. If you leave your job with an outstanding loan, you'll typically need to repay it quickly or it will be treated as a distribution.
Your investment strategy should be based on your age, risk tolerance, and retirement timeline. Here are some general guidelines:
- Younger investors (20s-40s) can generally afford to be more aggressive with a higher percentage in stocks for potential growth.
- Mid-career investors (40s-50s) might adopt a more balanced approach with a mix of stocks and bonds.
- Near-retirement investors (55+) often shift toward more conservative allocations to preserve capital.
Target-date funds are a popular option that automatically adjusts the asset allocation to become more conservative as you approach your target retirement date. However, they may not be ideal for everyone's specific situation.
It's important to review your investment choices regularly and consider consulting with a financial advisor for personalized guidance.
Required Minimum Distributions (RMDs) are mandatory withdrawals that you must take from your traditional 401(k) and traditional IRA accounts once you reach a certain age (currently 73, increasing to 75 by 2033).
The amount you must withdraw each year is calculated based on your account balance and life expectancy according to IRS tables. Failing to take your RMD can result in a tax penalty of 25% of the amount not withdrawn (reduced to 10% if corrected in a timely manner).
Unlike Roth IRAs, Roth 401(k) accounts are subject to RMDs. However, you can avoid RMDs on Roth 401(k) funds by rolling them over to a Roth IRA.
To estimate your 401(k) balance at retirement, you need to consider:
- Your current 401(k) balance
- Your monthly contributions (including any employer match)
- Your expected rate of return on investments
- The number of years until retirement
- Potential salary increases over time
Our 401(k) calculator takes all these factors into account to give you an estimate of your future balance. However, remember that market returns fluctuate and are not guaranteed, so it's wise to run calculations with different return assumptions to see a range of possible outcomes.
For a more comprehensive retirement plan, consider consulting with a financial advisor who can look at your entire financial picture, including other retirement accounts, Social Security benefits, and expenses in retirement.
Whether a 401(k) is sufficient for your retirement depends on several factors, including:
- Your desired lifestyle in retirement
- Your expected expenses (including healthcare)
- Other sources of income (Social Security, pensions, other investments)
- How much you've been able to save
- How long you expect to live in retirement
Many financial experts recommend saving 10-15 times your annual salary by retirement age. For additional retirement security, consider supplementing your 401(k) with other retirement accounts like IRAs, taxable investment accounts, or health savings accounts (HSAs).
Creating a diversified retirement strategy with multiple income sources can provide more security and flexibility in retirement.
