401(k) Calculator
Project your 401(k) balance, employer match, and retirement income.
Use this free 401(k) calculator and 401k calculator to estimate retirement savings growth, employer match, future balance, and possible annual withdrawals.
How does the 401(k) calculator estimate my future balance?
It adds your annual contributions and employer match, grows salary by your selected salary-growth rate, and compounds the account using your expected annual investment return.
What employer match should I enter?
Enter the match formula from your plan. For example, if your employer matches 100% of the first 6% of pay, enter a 100% match and a 6% match limit.
Does the 401(k) calculator include taxes or plan fees?
No. It is a planning estimate and does not model taxes, early-withdrawal penalties, investment fees, vesting rules, or annual IRS contribution limits.
What withdrawal rate should I use for retirement income?
Many people start with 3% to 4% as a conservative planning range, then adjust based on age, market risk, taxes, Social Security, pensions, and desired legacy goals.
Can I use this calculator for a Roth 401(k)?
Yes for balance-growth planning. Roth and traditional 401(k) accounts can use similar contribution and growth math, but the tax treatment of withdrawals is different and is not modeled here.
