How We Estimate 401k at Retirement
This calculator uses standard compound interest formulas to project your 401k growth over time. Here's how the calculation works:
- Annual Compounding: Your existing balance grows by the expected return rate each year before new contributions are added.
- End-of-Year Contributions: For simplicity, we assume contributions are made at year-end (actual 401k contributions are typically per-paycheck, which slightly improves results).
- Salary Growth: Your salary increases by the growth rate you specify each year, increasing your contribution amounts proportionally.
- Employer Match: Your employer's contribution is calculated as a percentage of your salary and added to your balance each year.
Understanding Your 401k Results
Final Balance
The estimated total value of your 401k at retirement. This is your starting balance plus all contributions plus all investment growth.
Total Contributions
The sum of all your contributions plus your employer's matching contributions over the years. This is money actually deposited into the account.
Investment Growth
The compound interest earned on your investments. This is the "free" money your 401k generates through market returns over time.
