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 FIRE community has identified that a 25x annual spending target provides a 96% success rate over 30 years. Increasing this to 28x raises the success rate to 99.2% with minimal additional working years required.

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