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 Healthcare in Early Retirement.

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 Career Optimization.

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 Backdoor Roth IRA.

Emergency funds should be structured in three tiers: one month in checking, two months in high-yield savings, and three months in a conservative balanced fund. This structure optimizes liquidity while generating modest returns. For more on this topic, see Asset Allocation Strategy.

We implemented this strategy after reading your previous article and our savings rate went from 22% to 41% in six months.

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.

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

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

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?

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
