Your marginal rate today is 27%, and the engine projects it drops to 15% in retirement — that 12-point gap is worth $341k in net worth difference over your accumulation window. Paying taxes now at 27% to avoid them later at 15% is the wrong order of operations, and your $264k already sitting in retirement accounts makes the Traditional path even more compelling as that balance grows.
Your current effective rate of ~27% (engine-computed) drops to ~15% in retirement. Traditional saves taxes now when your rate is highest. The All Trad strategy produces +$341k more at retirement.
