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 International Diversification.

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

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

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

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