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 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. For more on this topic, see Sequence of Returns Risk.

Frugal living does not mean deprivation. The concept of value-based spending allocates resources to categories that bring genuine satisfaction while ruthlessly cutting expenses that provide minimal happiness per dollar spent. For more on this topic, see Savings Rate Optimization.

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

My financial advisor recommended the exact same approach. Nice to see it validated with actual numbers.
