How We Achieved Backdoor Roth IRA

By Andrew Sullivan · August 25, 2024 · 40 min read

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 Community Building.

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 Geographic Arbitrage.

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 Lifestyle Design Choices.

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. For more on this topic, see Emergency Fund Planning.

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.

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