How much should I contribute to my 401k?
1) At minimum: Contribute enough to get full employer match (typically 3-6% of salary) - it's free money with 100% instant return. 2) Ideal: 15% of gross income (including match) for comfortable retirement. 3) Max: $23,000/year ($30,500 if 50+) for 2024.
What are 401k tax advantages?
Traditional 401k: Pre-tax contributions lower taxable income now. $60K salary → contribute $6K → pay taxes on $54K. Money grows tax-deferred. Roth 401k: After-tax contributions, but withdrawals are tax-free in retirement. Choose Roth if young/low tax bracket, Traditional if high earner.
Can I withdraw from 401k early?
Before 59½: 10% penalty + income tax (ouch!). Exceptions: $10K for first home, medical hardship, Rule of 55 (leave job at 55+). Loans: Borrow up to $50K, pay back with interest to yourself. Avoid early withdrawal - costs tens of thousands in lost growth.

🧩 Additional Notes & Tips
Employer match is a guaranteed return
If your employer matches contributions, missing the match is like refusing a pay raise. Aim to contribute at least enough to capture the full match before optimizing other goals.
Traditional vs Roth (simple framework)
Traditional contributions may reduce taxable income today; Roth contributions may provide tax-free withdrawals later. Many savers benefit from a mix to diversify tax risk.
