Outside of my 403(b) Base Program, which my employer matches 10% to my 5%, how much should I sock away in a 403(b) Supplemental? Currently, I contribute 5% to a 403(b) Supplemental, for a total of 20% of 110% of my paycheck. I fully fund a ROTH IRA every year, so I am wondering if I should be saving more of my paycheck to a more liquid asset. Michael, Haslett, MI
