The 401(k) is the most powerful wealth-building tool for employees. The 2024 limit is $22,500 ($30,000 with catch-up for 50+). At 8% annual return, maxing out for 30 years produces $3.2M — but only $675K is your money, $2.5M is compound growth! An employer match is FREE money: a 50% match on 6% of $100K salary adds $3K/yr — turning $6K into $9K annually. Not taking the full match is literally leaving money on the table. Starting at 25 vs 35 doubles your retirement balance with the same monthly contribution.
Employer Match & Vesting
Employer match is typically 50–100% of your contribution up to a cap (e.g., 6% of salary). Vesting determines when you own employer contributions. Always contribute at least enough to get the full match—it's free money.
Traditional vs Roth 401(k)
Traditional reduces taxable income now; Roth pays tax now for tax-free withdrawals. Choose based on whether you expect higher taxes now or in retirement. Many experts recommend a mix of both for tax diversification.
Early Withdrawal Penalty
Withdrawals before 59½ incur a 10% IRS penalty plus ordinary income tax. A $50K withdrawal at 35 in the 24% bracket: $5K penalty + $12K tax = $17K lost. Exceptions exist for hardship, disability, or 72(t) substantially equal payments.
401(k) Rollover to IRA
Direct rollover: have your plan administrator transfer funds to the new IRA—no tax withholding. Indirect rollover: 60 days to deposit; 20% withheld. Direct rollover avoids penalties.
Catch-Up Contributions
Workers 50+ can contribute an extra $7,500 in 2024—$30,000 total. Catch-up helps late savers accelerate retirement readiness. Limits are indexed for inflation.
Expert Tips
- Always get the full employer match—instant 50–100% return
- Increase contribution 1% per year until maxed
- Choose low-cost index funds—fees erode returns
- Use catch-up at 50+ if behind on savings
