How Does Roth 401K Affect Take Home Pay? 
That is a great question ! One of the best things about a Roth IRA is that you fund it with after-tax dollars . That means unlike your health insurance or 401k deductions that come out of your paycheck before taxes are figured , what you put into your Roth is already taxed . The benefit there is that when you start taking money out of it in retirement , you do n't have to pay taxes on it then . This can be a terriffic blessing ! I hope that helps , thanks for asking !
