Like others have mentioned, the effect of After tax 401k and Roth 401k is similar. That is true in theory but reality is usually different. Let us first talk about the difference between traditional 401k and Roth 401k - if you contribute to traditional 401k, you can deduct the contributions in the current year from your taxable income. If you made 100k and you contribute 18k to your traditional 401k, then your taxable income reduces to 82k.
