401(k) Calculator
Estimate your 401(k) growth over time with employer match and contributions.
About this Tool
The 401(k) Calculator is a powerful financial planning tool designed to project the future value of a 401(k) retirement account. By inputting key variables such as current age, desired retirement age, current 401(k) balance, annual salary, contribution percentages (both employee and employer), and the expected annual rate of return, users can receive a detailed forecast of their potential retirement savings. This calculator not only provides a future lump-sum estimate but also helps individuals understand the profound impact of long-term, consistent investing. It illustrates the power of compound interest, the value of employer matching contributions (often referred to as 'free money'), and the importance of starting to save early. The tool assumes a standard 2% annual salary increase to provide a more realistic long-term projection. By visualizing their potential nest egg, users can make informed decisions about their savings strategy, adjust their contributions, and assess whether they are on track to achieve a financially secure retirement. It serves as an essential first step in comprehensive retirement planning, empowering users to take control of their financial future.

Pro Tips
- !
Maximize Employer Match
Always contribute at least enough to receive the full employer match. It is an instant, guaranteed return on your investment and is the fastest way to accelerate your savings.
- !
Increase Contributions Annually
Try to increase your contribution percentage by 1% each year, perhaps when you get a raise. These small, regular increments can have a huge impact on your final balance over time without drastically affecting your take-home pay.
- !
Stay the Course During Market Volatility
Market downturns are a normal part of investing. Continuing your regular contributions during these times means you are buying more shares at a lower price (dollar-cost averaging), which can significantly accelerate growth when the market recovers.
- !
Review Your Investments
Don't just 'set it and forget it.' Review your 401(k) investments annually to ensure they are still aligned with your risk tolerance and time horizon. Consider rebalancing if your asset allocation has drifted.
Examples
Scenario: Young Professional Starting Out
A 25-year-old starts a new job with a $60,000 salary and no prior 401(k) savings. They decide to contribute 8% of their salary, and their employer matches 50% of the first 6% (a 3% match).
- Enter Current Age: 25
- Enter Retirement Age: 65
- Enter Current Balance: 0
- Enter Annual Salary: 60000
- Enter Your Contribution: 8%
- Enter Employer Match: 3%
- Enter Expected Return: 7%
- The result shows how even modest, early contributions can grow into a substantial sum over 40 years, demonstrating the power of time and compounding.
Scenario: Mid-Career Catch-Up
A 40-year-old with $100,000 in their 401(k) realizes they need to save more aggressively. Their salary is $90,000, and they have a 5% employer match.
- Enter Current Age: 40, Retirement Age: 65
- Enter Current Balance: 100000
- Enter Annual Salary: 90000
- Enter Employer Match: 5%
- First, calculate with their current 8% contribution. Then, re-calculate with an increased 15% contribution.
- This comparison clearly illustrates how increasing contributions later in a career can still have a dramatic, positive impact on the final retirement balance.
