Congrats on keeping your expenses low compared to your income! You are in a great position. I'm re-ordering your questions a little, hope this helps!
My company matches 100% up to 6% for my 401k. Right now I am putting just 6% to my 401k. Should I increase it?You are in a position where you could contribute the max of $17,500 per year. Does the 6% include commissions or is it only base? You would want to contribute $1,458.33 per month in order to max it out. Use a paycheck calculator (
http://www.adp.com/tools-and-resources/calculators-and-tools/payroll-calculators/salary-paycheck-calculator.aspx) to see what your paycheck will be if you max it out. You will pay less taxes, so the difference will be less than you think.
Since you have an extra $2,700 a month, I would increase your 401k contribution to that amount from now until Dec 31st to put as much in your 401k as possible for 2014. Then, you can lower your contribution to $1,458.33 per month to evenly contribute during 2015.
I'm also putting 1% into a Roth 401k through Fidelity as well. I have no idea why I'm doing this or how its different from my 401k. What should I do with this?Here is some info on Roth 401k:
http://en.wikipedia.org/wiki/Roth_401%28k%29Basically, your regular 401k is pre-tax contributions and you are not taxed until you withdraw in retirement. With the Roth 401k, you contribute post-tax and then you're not taxed when you withdraw. It makes sense to do the Roth 401k if you expect your tax bracket to be higher during retirement than it is now. I suspect that is not the case since your income is high now. Your contributions for both the traditional 401k and Roth 401k cannot exceed a total of $17,500 per year. So I would recommend maxing out the traditional 401k instead.
Should I start a separate Roth IRA?After maxing out the 401k, I would put $5,500 in Roth IRA. You will pay tax now, but have the benefit of tax-free withdrawals at retirement. You have until April 15, 2015 to contribute $5,500 that will count towards 2014 tax year.
I should just pay off this credit card debt now right?Since it's 0% interest until March, and you already have the cash to pay it, I would focus on putting as much in the tax advantaged accounts (401k and IRA) before March. As long as you know - THIS HAS TO BE PAID BY MARCH. You didn't say the reason for the credit card debt, but my advice would be to make sure you don't get into the position of having credit card debt again. In March, use $25k of your $38k to pay off the debt.
Should I work on paying off my house? Should I refinance? What should I do with my excess money each month? I estimate that will be at least $2700.I would put your excess money to work in this order:
1) max out 401k
2) max out Roth IRA
3) pay remaining extra towards the mortgage
4) once mortgage is paid off, invest in taxable accounts (like Vanguard index fund)
You could debate paying off the mortgage at 5% vs. investing extra cash. Paying off the mortgage early is a guaranteed 5% return, while there's always uncertainty with stocks. Of course, you could do both too (like put 50% of extra cash towards mortgage and 50% towards stocks).
