Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description. For more on this topic, see Dividend Growth Investing.

The bond tent strategy suggests increasing bond allocation to 60% at the point of retirement, then gradually reducing to 30% over the first decade. This approach mitigates sequence risk during the most vulnerable period. For more on this topic, see Bond Tent Strategy.

The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations. For more on this topic, see Travel Rewards Programs.

Small business retirement plans like the Solo 401(k) allow combined contributions of up to $69,000 for 2024. Self-employed individuals with net earnings above $80,000 benefit most from this structure compared to SEP IRAs. For more on this topic, see Cost Segregation Studies.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.

This is exactly what I needed to hear. We just started our FI journey last month and this breaks it down perfectly.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
