With $42K gross, the $6200 deduction and $3950 exemption puts you in the 15% (plus whatever state tax) marginal tax bracket.
If you think you will be in a much lower bracket after retirement, do traditional.
If you think you will be in a much higher bracket after retirement, do Roth.
If you aren't sure, just put as much as you can into either.
One consideration based on your specific situation: if you need to save to buy a house, you can withdraw your Roth contributions at any time. Personally I'd wait on a house until I had enough taxable money accumulated after maximizing tax-advantaged savings (either traditional or Roth) every year, but YMMV.
Good luck!
I mostly agree with this.
Only thing I would add is for you to think about if you expect your annual earnings to increase significantly over the next decade, I might consider putting more toward a Roth IRA/401k today since the benefit of contributing post-tax will go down as your income goes up.
Otherwise, it's hard to go wrong either way.
It's infinitely more important that you save
something in those accounts, and do it consistently.
"From what i have been gathering on this forum it sounds like i should be doing traditional since my income is so low. "Exact opposite. You should contribute to Roth because your income is so low. MDM summarized it well. At a 15% marginal bracket, you are probably paying +/-10% effective tax rate (total taxes / total income). Your effective rate will increase rapidly once you reach the 25% marginal bracket. This assumes, of course, that you expect your future earnings to increase substantially.
