Maximizing Employer Matching

Employer matching is free money — contribute at least enough to capture the full match before funding other accounts. A 50% match on 6% of salary is an immediate 50% return.

Vesting schedules may require years of employment before matched funds are fully yours. Check your plan documents.

Contribution Limits and Catch-Up

The annual 401(k) limit is $23,000 for 2024–2025 ($30,500 if age 50+). Increasing contributions by 1% per year often goes unnoticed in take-home pay but dramatically boosts retirement balances.

Traditional 401(k) contributions reduce taxable income now; Roth 401(k) contributions grow tax-free if your plan offers them.

Key Takeaways

  • Always capture the full employer match first.
  • Increase contributions 1% annually until you hit your target rate.
  • Low-cost index funds beat expensive actively managed options.
  • Do not cash out when changing jobs — roll over to an IRA or new 401(k).
