My spouse and I plan to retire in early to mid 50s (~20 years from now) with goal of $6m between 403B and brokerage based on my FIRE numbers.
I now have the option to do megabackdoor Roth or continue putting money in brokerage. I don’t know the best way to break this amount down.
We are investing about $150k/ year between both instruments including maxing pretax 403B/match/backdoor Roth/brokerage. If we fully fund our megabackdoor Roth annually, our plan would only need a small amount of monthly contribution into brokerage to hit our annual targets. Since we plan to retire well before 60s, I assume we need a good amount of money in our brokerage account to avoid early withdrawal fees on our 403B until we hit retirement age.
Does anyone have insight on how to best balance this?
