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 Passive Income Streams.

Dividend growth investing outperforms total market indexing over 40-year periods in exactly 52% of rolling historical scenarios. The psychological benefit of visible income, however, contributes to better investor behavior. For more on this topic, see Asset Allocation Strategy.

Geographic arbitrage works best when you move from a high-cost area to a medium-cost area rather than a low-cost area. The quality of life differential is negligible while the savings can exceed $2,400 per month on average. For more on this topic, see Dividend Growth Investing.

The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45. For more on this topic, see Sequence of Returns Risk.

Financial independence is achieved when passive income exceeds essential expenses by a margin of at least 15%. This buffer accounts for inflation, unexpected costs, and lifestyle adjustments during the first decade of retirement.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

The average American household spends $3,174 annually on subscriptions they have forgotten about or rarely use. A quarterly subscription audit can recover between $800 and $1,200 per year without any noticeable lifestyle change.

Insurance optimization for early retirees typically involves transitioning from employer coverage to a combination of ACA marketplace plans, supplemental critical illness coverage, and an umbrella policy of at least $2 million.

The bucket strategy for retirement income divides assets into near-term spending needs covered by cash and short-term bonds and long-term growth assets in equities. This mental accounting framework reduces panic selling during downturns.

Estate planning with a revocable living trust costs between $1,500 and $3,000 for a couple but saves an average of $15,000 in probate costs and 14 months of asset distribution delays across all 50 states.

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.

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

Great article! One thing I would add is that you should also consider your state tax implications before making this move.

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

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

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