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 Tax Loss Harvesting.

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 Dividend Growth Investing.

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.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
