How This 401K Calculator Works
This free 401K calculator (also searched as a 401 calculator) estimates your projected retirement balance by compounding monthly contributions and employer match at your expected annual return. Use it to compare match scenarios and plan long-term savings.
Retirement Savings Tips
- Start as early as possible — compound interest rewards time more than contribution size.
- Always contribute enough to capture the full employer match. It is free money.
- Increase contributions by 1% each year as your income grows to stay on track for retirement.
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 6–8% per year over the long term. Lower rates are more conservative. This calculator does not account for inflation or taxes.

How to use
- Enter your current age and the age you want to model as retirement.
- Add current savings and a monthly contribution amount.
- Set an assumed annual return and employer-match percentage based on your plan details.
- Review the projected balance and contribution/growth breakdown, then test more than one return assumption.
Worked example
A saver aged 35 could enter a retirement age of 65, current savings of $25,000, monthly contributions of $500, a 5% assumed annual return, and a 50% employer-match input. The projection shows how those assumptions combine; it is not a promised balance or a recommendation to use a particular return.
Treat a retirement projection as a scenario
The projection is driven by the ages, current savings, monthly contribution, employer match, and annual-return assumption entered in the form. The chart separates personal contributions, employer contributions, and modeled growth so you can see which assumptions drive the result.
Investment returns vary and contributions or employer-plan rules can change. This calculator does not establish eligibility, contribution limits, vesting, fees, tax treatment, or an appropriate investment allocation. Check your plan documents and consider a range of return assumptions rather than relying on one projection.
Frequently asked questions
What inputs affect the projected balance?
The form uses current age, retirement age, current savings, monthly contribution, assumed annual return, and employer match.
Is the projected return guaranteed?
No. The annual return is an assumption for the scenario. Actual investment performance can be higher or lower, including negative periods.
Does this calculate 401(k) contribution limits?
No. It projects a balance from the values entered and does not verify current IRS limits or a specific plan’s rules.
What does the monthly withdrawal figure mean?
It is an illustrative figure calculated by the page using a 4% rule display, not a guarantee that a particular withdrawal is sustainable.
