401(k) Tips & Best Practices
Always Get the Full Match
Contribute at least enough to capture your full employer match — it’s essentially free money and an instant 50–100% return on those dollars.
Start Early
Time in the market is your greatest advantage. Starting at 25 vs 35 can result in more than double the final balance thanks to compound growth.
2024 Contribution Limits
The IRS limit for 401(k) contributions is $23,000/year in 2024 (under 50). If you’re 50+, you can add a $7,500 catch-up contribution for a total of $30,500.
Roth vs Traditional
Choose Traditional if you expect lower taxes in retirement. Choose Roth if you expect higher taxes later or want tax-free withdrawals in retirement.
Diversify Investments
Spread contributions across stocks, bonds, and index funds. Target-date funds automatically rebalance based on your expected retirement year.
Avoid Early Withdrawals
Taking money out before age 59½ triggers a 10% early withdrawal penalty plus income taxes. Let compounding work for you.

Rule of 25 & 4% Rule
Rule of 25: Multiply your annual retirement expenses by 25 to estimate your needed nest egg. E.g., $50,000/year × 25 = $1,250,000 needed.
4% Rule: You can safely withdraw 4% of your portfolio per year in retirement with a high probability of not outliving your money (based on a 30-year retirement).
4% Rule: You can safely withdraw 4% of your portfolio per year in retirement with a high probability of not outliving your money (based on a 30-year retirement).
