💼 401(k) Calculator
Estimate how your 401(k) balance could grow over time based on your contributions, employer match, and expected investment returns.
How a 401(k) grows over time
A 401(k) is an employer-sponsored retirement account. Your contributions (a percentage of salary) are invested, often with an employer match added on top, and the balance compounds over the years until retirement.
How this calculator works
Enter your current balance, salary, contribution percentage, employer match rate and match limit, expected annual return, and years until retirement. The calculator applies your combined monthly contributions and compounds the balance monthly using your expected return.
This is a simplified projection for general planning purposes. It does not account for salary changes, contribution limits, fees, taxes, or market volatility, and actual results will vary.
