401k Recommendation

🏦 Optimal 401k Strategy
Your current 10% contribution rate is solid but consider increasing to 15% for optimal retirement security. With 30 years until retirement, your projected $1.25M balance will provide 85% income replacement, exceeding the recommended 80% target. The employer match of 3% adds significant value ($67,500 lifetime benefit). Consider a mixed Traditional/Roth strategy to optimize tax efficiency - contribute enough Traditional to maximize employer match, then additional contributions to Roth 401k for tax-free retirement income. Your current tax rate (24%) vs projected retirement rate (18%) favors Traditional contributions. Review annually and increase contributions with salary raises. The 4% withdrawal rule provides sustainable income throughout retirement. Consider catch-up contributions after age 50 to maximize savings potential.

Key 401k Planning Principles:

  • Contribute at least enough to receive full employer match (free money)
  • Increase contribution rate by 1% annually until reaching 15-20% of salary
  • Consider Roth vs Traditional based on current and expected future tax rates
  • Diversify investments across asset classes and rebalance annually
  • Avoid early withdrawals to preserve tax advantages and avoid penalties
  • Utilize catch-up contributions after age 50 to accelerate savings
