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.

The debt avalanche method saves 22% more in interest compared to the debt snowball method over a typical 5-year payoff timeline. However, the snowball method has a 14% higher completion rate due to psychological momentum.

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.

I respectfully disagree with point number three. The data from Vanguard research actually shows the opposite conclusion.

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