What This 401K Calculator Shows
This calculator gives a practical estimate using common 401K planning factors.
Future 401K Balance
The estimated value of your 401K account at your selected retirement age.
Employee Contributions
The estimated amount you may contribute from your salary over time.
Employer Match
The estimated employer contribution based on your match percentage and match limit.

The estimated annual and monthly income based on your selected withdrawal rate.
Savings Gap

401K Calculator Example
Suppose you are 35 years old, plan to retire at 65, earn $75,000 per year, and already have $50,000 in your 401K.
If you contribute 8% of salary and your employer matches part of your contribution, the calculator can estimate your future 401K balance, total employee contributions, employer match, investment growth, and retirement income.
Why Employer Match Matters
Employer match can be an important part of 401K growth because it adds money to your account based on your contribution and your employer’s plan rules.
If your employer offers a match, contributing enough to receive the available match may help increase long-term retirement savings.
401K Contributions and Compound Growth
A 401K may grow through regular contributions and compound returns. Compounding means your savings may earn returns, and those returns may also earn returns over time.
The longer your money stays invested, the more time it may have to benefit from compounding.
