401 Calculator FAQs
What is a 401K and how does this calculator help?
A 401K is a tax-advantaged employer-sponsored retirement account. This calculator projects your balance at retirement based on your current savings, monthly contributions, employer match, and expected annual investment return.
How is the employer match calculated?
Enter the employer match as a percentage of your monthly contribution. For example, 50% means your employer adds $250 for every $500 you contribute. The exact match structure varies by employer.
What annual return rate should I use?
A commonly used estimate for a diversified stock-heavy portfolio is 6β8% per year over the long term. Lower rates are more conservative. This calculator does not account for inflation or taxes.
