UNDERSTANDING A 401(K)
What is a 401(k) plan?
A 401(k) is an employer-sponsored retirement savings plan that allows eligible employees to save and invest money for retirement. Contributions are generally made through payroll deductions.
Depending on the plan, an employer may also contribute money through a matching contribution. Over time, your own contributions, employer contributions and investment returns can all contribute to the growth of your retirement account.
Employer Match
Some employers match part of an employee's contribution according to the rules of the workplace retirement plan.
Investment Growth
The investments inside a retirement account may gain or lose value depending on market performance.
HOW TO USE THE CALCULATOR
Estimate your retirement balance in four steps
Use realistic assumptions and review different scenarios to understand how your savings strategy could affect your future retirement balance.
Enter Your Current Balance
Start with the amount already saved in your 401(k) or another retirement account included in your calculation.
Add Your Contributions
Enter the amount you expect to contribute each year to your workplace retirement plan.
Include Employer Matching
Add your employer's matching percentage and the portion of your salary that qualifies for the match.
Review the Projection
Review the projected balance and see how contributions, employer matching and investment growth contribute to it.
401(K) GROWTH FORMULA
How the retirement projection works
The calculator estimates future retirement savings by applying an assumed investment return to your existing balance and contributions over the remaining years until retirement.
FV = PV(1+r)n + C
Contributions and employer matching are incorporated into the
annual projection.
PV represents the current balance, r represents the assumed annual return, n represents the years until retirement and C represents recurring contributions.
PV
Current retirement balance
r
Assumed annual investment return
n
Years until retirement
C
Recurring contributions
RETIREMENT SAVINGS GROWTH
THE POWER OF COMPOUND GROWTH
Time can become one of your biggest advantages
Retirement savings can benefit from compounding because investment returns may themselves generate additional returns over time.
The longer money remains invested, the more time there may be for contributions and investment growth to build on one another. This does not guarantee a specific result, but it illustrates why starting early can be valuable.
Start Early
More time can allow savings to compound.
Contribute Consistently
Regular contributions can build the account over time.
Capture Available Matching
Employer contributions can add another source of savings.
FACTORS THAT AFFECT RETIREMENT SAVINGS
Your future balance depends on more than contributions
Retirement outcomes can change significantly when you adjust contribution levels, time horizon, employer matching or assumed investment returns.
Contribution Rate
Increasing your contribution rate can put more money to work for retirement and potentially increase your future balance.
Employer Match
A matching contribution can add money to your retirement account without requiring the same amount to come directly from you.
Time Until Retirement
More years can provide additional time for contributions and investment returns to compound.
Investment Return
Higher assumed returns can produce a larger projection, but investment performance is uncertain and not guaranteed.
Salary Growth
Changes in salary can affect contributions and potentially the amount of compensation eligible for employer matching.
Fees and Expenses
Investment and plan expenses can reduce the amount of money ultimately available in a retirement account.
RETIREMENT SCENARIOS
Compare different assumptions before making a plan
A retirement calculator becomes more useful when you test different assumptions rather than relying on one projection.
You can explore what happens if you contribute more, retire later, receive a different employer match or use a different expected return assumption.
Increase Contributions
Test how saving more each year could affect the projected retirement balance.
Retire Later
Compare the potential impact of giving contributions and investments additional time to grow.
Change the Match
Review how different employer matching assumptions can influence your projected savings.
Test Returns
Compare conservative and higher return assumptions to understand the range of possible outcomes.
RETIREMENT PLANNING TIPS
Small decisions can influence long-term savings
Know Your Employer Match
Review your workplace plan to understand how employer matching works and which contributions qualify.
Increase Contributions Gradually
Consider increasing your contribution when your income rises instead of waiting until later in your career.
Review Investment Choices
Understand the investment options, diversification and fees available through your retirement plan.
Revisit Your Plan
Retirement planning is not a one-time decision. Review your assumptions as your income, goals and time horizon change.

401(K) CALCULATOR FAQ
Common questions about 401(k) planning
A 401(k) calculator estimates how your retirement account could grow based on your current balance, contributions, employer matching, expected investment return and time until retirement.
An employer match can add money to your retirement account based on the rules of your workplace plan. The exact amount depends on the matching formula and eligible compensation.
There is no guaranteed investment return. It can be useful to test multiple assumptions rather than relying on one rate when evaluating a long-term retirement plan.
The basic projection focuses on the future account balance based on your inputs. A future balance should also be considered in terms of purchasing power because inflation can reduce what money buys over time.
No. The result is a projection based on assumptions. Investment performance, contributions, salary, employer matching, fees, taxes and retirement timing can all differ.
Starting earlier gives contributions and potential investment returns more time to compound. It can also give you more flexibility to adjust your savings strategy later.
