401(k) Calculator
This tool gives you a clear picture of how your 401(k) account can grow over time so you can make smarter financial decisions today for a more secure future.
What Is a 401(k) Plan?
A 401(k) is a retirement savings plan offered by many employers that allows employees to contribute a portion of their salary into long-term investments. These contributions grow over time, often with employer matching and tax advantages.
Key features include:
- Employee contributions from paycheck
- Employer matching contributions
- Tax-deferred growth
- Long-term investment potential
Understanding how these factors combine is essential for building a strong retirement fund.
