Estimate the future value of your 401(k) retirement account. See how your contributions, employer match, and compound interest can grow your nest egg over time. Plan your retirement with confidence.
A 401(k) is an employer-sponsored retirement savings plan that allows employees to contribute a portion of their pre-tax salary. Many employers offer matching contributions, which is essentially "free money" toward your retirement. Investment earnings grow tax-deferred until withdrawal.
Example: Age 30, retiring at 65 (35 years), $25,000 balance, $60,000 salary, 10% contribution ($6,000/year), 50% match on first 6% ($1,800/year), 7% return
Total annual contribution = $7,800
Future Value ≈ $1,150,000+
| Age Group | Employee Contribution Limit | Total Limit (Employee + Employer) |
|---|---|---|
| Under 50 | $23,000 | $69,000 |
| Age 50+ (Catch-up) | $30,500 | $76,500 |
❓ How does employer matching work?
Common match formulas include:
• 100% match on first 3% of salary + 50% match on next 2% (total 4% match on 5% contribution)
• 50% match up to 6% of salary (3% match on 6% contribution)
• Dollar-for-dollar match up to 4-6% of salary
Always contribute enough to get the full employer match — it's an instant 50-100% return on your money!
❓ When can I withdraw from my 401(k)?
• Age 59½: penalty-free withdrawals
• Age 55: penalty-free if separated from service
• Age 72: Required Minimum Distributions (RMDs) begin
Early withdrawals before 59½ incur a 10% penalty plus income taxes.
❓ What's the difference between Traditional and Roth 401(k)?
• Traditional: Pre-tax contributions, taxes due upon withdrawal
• Roth: After-tax contributions, tax-free withdrawals in retirement
Many employers now offer both options.
❓ What investment return should I assume?
• Conservative (bonds): 4-5%
• Moderate (60/40 stocks/bonds): 6-8%
• Aggressive (80%+ stocks): 8-10%
Historical S&P 500 average: ~10%
❓ Can I borrow from my 401(k)?
Most plans allow loans up to 50% of your vested balance ($50,000 max). Loans must be repaid with interest, typically within 5 years. Defaulting triggers taxes and penalties.
💡 Pro Tip: The single most effective way to boost your 401(k) balance is to increase your contribution rate by 1% each year until you reach at least 15% of your salary. Most people don't notice a 1% decrease in take-home pay but see dramatic growth over time.
