What is a 401k?

A 401(k) is an employer-sponsored retirement savings plan that allows employees to save and invest a portion of their paycheck before taxes are taken out. Taxes are paid when the money is withdrawn in retirement.

2024 401k Contribution Limits

  • Employee Contribution: $23,000 (under age 50)
  • Catch-up Contribution: Additional $7,500 (age 50+)
  • Total Limit (including employer): $69,000 or $76,500 with catch-up

Understanding Employer Matching

Many employers offer matching contributions as an incentive. A common match formula is "50% match up to 6% of salary," which means:

  • If you contribute 6% of your salary, your employer adds 3%
  • This is essentially free money - always try to get the full match!
  • Match formulas vary by employer (some offer 100% match)

Benefits of a 401k

  • Tax-Deferred Growth: Your investments grow without being taxed until withdrawal
  • Lower Taxable Income: Contributions reduce your current taxable income
  • Employer Match: Free money that boosts your savings
  • Automatic Saving: Contributions are deducted from your paycheck
  • Higher Limits: Contribution limits are higher than IRAs

401k vs Roth 401k

  • Traditional 401k: Pre-tax contributions, taxed at withdrawal
  • Roth 401k: After-tax contributions, tax-free withdrawals

Tips for Maximizing Your 401k

  1. At minimum, contribute enough to get the full employer match
  2. Increase contributions by 1% each year
  3. Take advantage of catch-up contributions after age 50
  4. Review and rebalance your investments annually
  5. Avoid early withdrawals (10% penalty before age 59.5)
