Estimate your 401(k) balance at retirement with employer matching contributions. See how your savings, match, and compound growth build over time.
Your 401(k) is likely your largest retirement savings vehicle. With employer matching, tax deferral, and compound growth, it is one of the most powerful wealth-building tools available. This calculator projects your balance at retirement based on your current savings, contribution rate, and expected investment returns.
This comprehensive 401(k) calculator helps you project your retirement savings by accounting for your current balance, ongoing contributions, employer matching programs, and expected investment returns. Employer matching is one of the most powerful wealth-building opportunities available through workplace retirement plans, as it represents free money added to your savings on top of your own contributions. The calculator uses compound growth assumptions to show how your money multiplies over decades of investing. You can adjust contribution rates, employer match percentages, and expected returns to see how different scenarios impact your final balance. Understanding your 401(k) projection helps you make informed decisions about contribution levels, fund selection, and whether you need to supplement with other retirement accounts like IRAs.
Result: At age 65, your 401(k) would be approximately $1,187,000. Your total contributions over 35 years would be $260,000 (you: $210,000 + employer match: $50,000), meaning compound growth added roughly $927,000 in investment returns.
A 401(k) plan is an employer-sponsored defined contribution retirement account that allows employees to save and invest a portion of their paycheck before taxes are taken out. For 2026, the employee contribution limit is $23,500 ($31,000 if you are age 50 or older).
Employer matching is essentially free money for your retirement. A common match formula is 50% of employee contributions up to 6% of salary. If you earn $80,000 and contribute 6% ($4,800), your employer adds $2,400.
The power of tax-deferred compounding is substantial. A $500 monthly contribution earning 7% annually grows to approximately $566,000 over 30 years. The same amount in a taxable account (assuming 24% tax bracket on gains) would grow to only about $430,000.
Traditional 401(k) contributions reduce your current taxable income, while Roth 401(k) contributions are made with after-tax dollars but grow and are withdrawn tax-free in retirement. The choice depends on whether you expect your tax rate to be higher or lower in retirement.
