<prompt> Human: They match up to 50 for both to the full amount,no cap. Right now I am maxing out my traditional 401K at 17.5K, should I consider splitting off a portion of my contribution into the Roth? How do I calculate the proscons of this?  <response>: It really depends on your tax bracket now and where you expect your tax bracket to be in the future.In my case, I contribute enough pre-tax to get down to the 15 bracket and then the rest Roth. I expect to be roughly in the 15 bracket in retirement assuming things stay similar to now, which they probably wont so theres no sense in paying more than that now to have more Roth money. One important factor is whether or not you can afford to max it if youre making Roth contributions. If youre contributing 17.5k now but could only contribute say 16.5k to the Roth because of the taxes you have to pay, youre missing out on 500 matching.
