OK, I think I follow you on that. What did you do with the Roth? Just take $3000 and grow it 10% each year? $3,000 + 300 = $3,300 at the end of year one, etc?
Then, at the end of the scenario, apply the new tax bracket to the traditional total only? And the Roth still came out ahead?
Yes, that's exactly what I did. Tradional total value $383,162, Roth $324,545. When withdrawing the money, I plussed up the Traditional so that the after tax amounts were the same. This is what kills the Traditional (at least in this model).
I'll try and modify the model as you suggested and see what we get.
