How to Use the 401(k) Calculator

Step 1: Enter Your Personal Information

• Current Age: Enter your age today (must be 18 or older)
• Retirement Age: When do you plan to retire? Most people retire between 62-67 years old
• Current 401(k) Balance: How much do you already have saved in your 401(k)? Enter $0 if you’re just starting

Step 2: Input Your Salary Details

• Annual Salary: Your current gross yearly income before taxes
• Annual Salary Increase: Expected yearly raise percentage. The average is 2-3% annually, though this varies by industry and career stage

Step 3: Set Your Contribution Amount

Choose between two contribution methods:

• Percentage: Enter what percent of your salary you contribute each paycheck (e.g., 6% is common). Many financial experts recommend contributing at least enough to get your full employer match, typically 15-20% total for retirement
• Dollar Amount: Enter a fixed monthly dollar amount you contribute (e.g., $500 per month)

Step 4: Enter Employer Match Details

• Employer Match Rate: What percentage does your employer contribute? Common matches are 50% or 100% of your contributions up to 3-6% of your salary. Check with your HR department for your specific match
• Example: If your employer offers a 50% match up to 6%, they’ll contribute 3% of your salary when you contribute 6%

Step 5: Set Expected Investment Return

• Expected Annual Return: The average yearly growth rate of your investments.

Step 6: Review Your Results

401(k) Planning Tips

Maximize Your Retirement Savings

1. Always Get the Full Match: If your employer matches up to 6%, contribute at least 6%. It’s free money—a guaranteed 100% return on that portion
2. Start Early: Thanks to compound interest, starting at age 25 vs. 35 can result in hundreds of thousands of dollars more at retirement
3. Increase Contributions Annually: Boost your contribution rate by 1% each year, especially when you get a raise
4. Consider Catch-Up Contributions: If you’re 50 or older, take advantage of catch-up contributions to save an extra money for retirement.
5. Review Investment Mix: Ensure your 401(k) investments align with your risk tolerance and retirement timeline
6. Don’t Cash Out Early: Early withdrawals before age 59½ typically incur a 10% penalty plus income taxes

Understanding Compound Interest

Compound interest is the “interest on interest” effect that makes your 401(k) grow exponentially over time. When your investments earn returns, those earnings are reinvested and generate their own returns. This snowball effect is why starting early is so powerful—even small contributions can grow substantially over 30-40 years.

Tax Advantages of 401(k) Plans

• Traditional 401(k): Contributions are pre-tax, reducing your current taxable income. You pay taxes on withdrawals in retirement
• Roth 401(k): Contributions are after-tax, but qualified withdrawals in retirement are tax-free

Frequently Asked Questions

How much should I contribute to my 401(k)?

Financial experts typically recommend contributing 10-15% of your gross income to retirement accounts. At minimum, contribute enough to get your full employer match. If possible, aim to max out the annual contribution limit. The IRS sets the limit for the annually 401k contribution limit. In 2026, the annual the 401(k) contribution limit is $24,500 for those under age 50, $32,500 for those over age 50, and $35,750 for those between the ages of 60 to 63.

What is a good employer match?

A typical employer match is 50% to 100% of your contributions up to 3-6% of your salary. Any employer match is valuable—it’s free money added to your retirement savings. The combined limit for employee + employer contributions to your plan is $72,000 in 2026.

Can I change my contribution amount?

Yes, you can typically adjust your 401(k) contribution rate at any time through your employer’s benefits portal. Some employers may have specific enrollment periods, so check with your HR department.

How accurate is this calculator?

This calculator provides estimates based on the assumptions you enter. Actual results will vary based on market performance, contribution changes, salary fluctuations, and other factors. It’s best used as a planning tool rather than an exact prediction.

Should I choose Traditional or Roth 401(k)?

Traditional 401(k) contributions reduce your current taxes but are taxed in retirement. Roth 401(k) contributions are taxed now but withdrawals are tax-free in retirement. Choose Traditional if you expect to be in a lower tax bracket in retirement, or Roth if you expect to be in a higher bracket. Many people split contributions between both.

What happens to my 401(k) if I change jobs?

You have several options: leave it with your former employer, roll it into your new employer’s plan, roll it into an IRA, or cash it out (not recommended due to taxes and penalties). Rolling over to an IRA or new employer’s plan maintains tax-deferred status.

When can I withdraw from my 401(k) without penalty?

You can make penalty-free withdrawals starting at age 59½. Withdrawals before this age typically incur a 10% early withdrawal penalty plus income taxes, though some exceptions exist for hardships, first-time home purchases, and certain medical expenses.
