The math is blunt: you're paying 22% on every dollar you contribute now, but your projected retirement rate is 18% — a 4-point spread that, compounded over your career, translates to a $367k difference in net worth in favor of Traditional. That gap exists entirely because you're deferring taxes from a higher bracket today into a lower one later, which is the exact scenario Traditional was designed for.
Your current effective rate of ~22% (engine-computed) drops to ~18% in retirement. Traditional saves taxes now when your rate is highest. The All Trad strategy produces +$367k more at retirement.

Tax laws change. Roth conversions, RMDs, and state tax changes can shift the calculus. This analysis uses current rates as a starting point.
