Estimate how current balance, salary deferral, employer match, and investment growth can build a retirement account over time.
Why this result matters
A workplace-retirement planning tool focused on salary deferrals, employer match, contribution caps, and long-run 401(k) growth. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This 401K calculator is designed for fast retirement-plan scenario testing. It combines current account balance, annual salary, employee deferral rate, employer match, expected return, and years to retirement so you can see how much of the final balance comes from contributions versus investment growth. It also highlights the current employee contribution cap and estimated tax deferral to make plan choices easier to compare.
Formula and method
The calculator applies the employee salary-deferral rate up to the current annual contribution cap, estimates employer match based on the plan match formula, converts total annual contributions into monthly investing, and compounds the account balance through the remaining years until retirement.
Example
If you have 120,000 already saved, earn 95,000 per year, contribute 10% of salary, receive a 100% employer match on the first 4% of pay, and earn 7% annually until age 65, the calculator estimates both the annual cash flow into the plan and the projected retirement balance.
FAQ
Short answers to the questions people often ask before or after using the tool.
Question
No. It uses a simplified contribution-cap and match model for planning. Real plans may have vesting schedules, true-up rules, Roth options, and other details this tool does not model.
Question
Because pre-tax employee 401(k) contributions can reduce current taxable income, which helps users compare the immediate tax impact of saving more.
Question
The contribution rate is the share of your salary that you defer into the plan. The employer match limit is the portion of salary the employer is willing to match under the plan formula.
