401(k) Calculator
Estimate how your current 401(k) balance, future contributions, employer match, investment growth, and time until retirement may work together to build your retirement savings.
See how contributions can compound
Estimate how regular employee contributions and long-term investment growth may build your 401(k) balance over the years leading up to retirement.
Understand the value of employer matching
Compare your own contributions with potential employer matching contributions to see how workplace benefits may increase the amount accumulating for retirement.
Estimate Your 401(k) Retirement Savings
Enter your salary, contribution rate, employer match, current balance, expected return, and inflation rate to estimate your projected 401(k) balance.
Enter Your Information
Use your best estimates to compare 401(k) contribution strategies and employer match scenarios.
Projected 401(k) Balance
Enter your numbers and calculate to see your estimate.
What these results mean
Your estimate combines employee contributions, employer matching contributions, projected investment growth, and inflation adjustments. Use the results as a planning estimate, not a guaranteed retirement outcome.
What Your 401(k) Projection Is Telling You
Your 401(k) results help show how your current balance, future contributions, employer match, investment growth, and time until retirement may combine over the years. Review the results together to understand where your projected balance is coming from.
Projected 401(k) Balance
This is the estimated value of your 401(k) at the end of the planning period based on the assumptions entered. It combines your current savings with future contributions and projected investment growth.
Your Contributions
This portion represents the money you contribute to the account over time. Increasing your contribution rate can raise the amount invested and may also increase the employer match available under your workplace plan.
Employer Match
Employer matching contributions can add significantly to long-term retirement savings. This result helps separate the amount contributed by your employer from the money you contribute personally.
Investment Growth
Investment growth reflects the portion of the projected balance that may come from compounding rather than direct contributions. The longer the money remains invested, the greater the potential influence of compound growth.
Look at where the future balance comes from
A useful 401(k) projection is not only about the final total. Compare your own contributions, employer contributions, and projected investment growth to see which parts of the plan are doing the most work and where adjustments may have the greatest impact.
Test more than one growth assumption
Investment returns are not guaranteed. Compare more conservative and more optimistic return assumptions to create a planning range rather than relying on a single projected balance.
How 401(k) Contributions and Employer Matching Can Change the Outcome
These simplified examples show how contribution rates, employer matching, time, and investment growth can affect a future 401(k) balance. Use them as a starting point for comparing your own retirement savings scenarios.
Capturing the Full Employer Match
Contributing enough to receive the available employer match can materially increase the amount flowing into a 401(k). Over a long career, those additional employer contributions also have more time to compound.
Increasing Contributions Mid-Career
Raising the contribution rate can increase both the amount saved directly and the amount available to compound over the remaining working years. Comparing the two rates can make the long-term difference easier to see.
Starting Earlier With a Smaller Balance
A smaller starting balance does not necessarily mean limited long-term potential. More years of regular contributions and compound growth can have a powerful effect when saving begins earlier.
Compare one change at a time
Test your contribution rate, employer match, retirement timeline, and expected return separately before combining changes. This can help you understand which adjustment has the greatest effect on the projected balance.
Focus on decisions you can control
Future investment returns are uncertain, but contribution rate, savings consistency, and how fully you use an available employer match are often more directly within your control.
Make More Informed 401(k) Saving Decisions
A 401(k) calculator helps connect the decisions you make today with the retirement balance you may build over time. Use it to compare contribution strategies, employer benefits, time horizons, and growth assumptions before making changes to your savings plan.
Choose a Contribution Level
Compare different contribution percentages or dollar amounts to see how increasing or reducing what you save may change the projected value of your 401(k) at retirement.
Maximize the Value of Employer Matching
See how employer contributions can supplement your own savings. Testing the match structure can help you understand whether increasing your contribution may allow you to capture more of an available workplace benefit.
Understand the Value of Time
Compare shorter and longer saving periods to see how additional years of contributions and compound growth may affect the future balance. This is especially useful when evaluating the impact of starting earlier.
Test Different Growth Assumptions
Investment returns can vary significantly over time. Compare conservative, moderate, and stronger return assumptions to see how sensitive your projected 401(k) balance may be to long-term performance.
Focus first on the variables you can control
Market returns cannot be known in advance, but your savings rate, contribution consistency, retirement timeline, and use of an available employer match are decisions you may be able to influence directly.
Planning question to consider
If your projected balance is lower than you would like, which change is most practical: increasing contributions, capturing more employer match, saving for additional years, or combining several smaller adjustments?
Useful for Anyone Building Retirement Savings Through a 401(k)
A 401(k) calculator can be useful whether you are making your first workplace contribution, increasing your savings rate, reviewing employer benefits, or checking whether your current plan is on track for retirement.
Workers Just Starting a 401(k)
If you recently enrolled in a workplace retirement plan, the calculator can help you see how even modest regular contributions may grow over a long time horizon and give you a clearer starting point for your savings strategy.
Employees With an Employer Match
If your employer offers matching contributions, use the calculator to understand how the match may add to your retirement balance and whether increasing your contribution could help you take fuller advantage of the benefit.
Mid-Career Savers Increasing Contributions
If your income has grown or your budget has more room for retirement savings, compare your current contribution rate with a higher rate to see how the change may affect your projected balance over the remaining working years.
Workers Approaching Retirement
If retirement is getting closer, the calculator can help you review whether your current 401(k) balance, contribution pace, and remaining time may produce the level of savings you want before leaving the workforce.
Revisit your 401(k) projection as your situation changes
Salary, contribution rates, employer matching formulas, investment performance, and retirement timing can all change over time. Update your assumptions periodically so the projection continues to reflect your current retirement savings plan.

Common Questions About Retirement Calculators
Retirement calculators are useful for exploring possibilities, comparing strategies, and organizing long-term decisions. These answers explain how to use retirement estimates responsibly and what to keep in mind when reviewing the results.
How accurate are retirement calculators?
Retirement calculators provide estimates based on the information and assumptions entered. Actual results may differ because investment returns, inflation, taxes, expenses, contribution levels, benefit rules, and retirement timing can change over time.
Which retirement calculator should I use first?
Start with the question you are trying to answer. You may want to estimate future savings, determine retirement income, evaluate withdrawals, compare account contributions, estimate a retirement age, or explore another specific retirement planning decision.
Should I use more than one retirement calculator?
Yes. Retirement planning involves several connected decisions, so using multiple calculators can provide a more complete picture. Savings, income, withdrawal, Social Security, pension, and retirement account calculations may each reveal a different part of your plan.
How often should I update my retirement estimates?
Revisit your estimates whenever there is a meaningful change in income, savings, investments, contribution levels, expected retirement age, expenses, or retirement goals. Periodic reviews can also help keep long-term assumptions realistic.
What assumptions matter most in retirement planning?
Important assumptions can include investment returns, inflation, retirement age, longevity, contribution levels, retirement spending, taxes, and future income sources. Small changes in long-term assumptions can sometimes create substantial differences in projected results.
Can a retirement calculator tell me exactly what I should do?
No. A calculator can help organize information and compare scenarios, but it cannot account for every personal, tax, legal, investment, or benefit consideration. Use the estimates as planning information rather than as a guarantee or individualized financial advice.
Use retirement calculators to compare possibilities, not predict the future
The greatest value usually comes from testing several realistic scenarios and seeing how changes in savings, time, income, withdrawals, and other assumptions affect your overall retirement outlook.
