Dave's suggestion for the way to fund your 15% toward retirement is this way.
1st- Fund your 401(k) or 403(b) up to your company matchBaby Step 5 is to save for your child(ren)'s college using tax-favored plans. Dave recommends first saving in an Education Savings Account (ESA) which is nick-named the "Education IRA". This allows you to put up to $2000 after tax into the account to grow tax-free. Above the ESA, Dave would recommend using a 529 that allows you to have complete control of the mutual funds at all times.
2nd-Above the match work toward maxing out your Roth IRA
3rd-If you still haven't got to 15% of your income then got back and finish using your 401(k) or 403(b)
This past two weeks was full of a lot of information and I am looking forward to taking these two steps a lot more seriously soon. We are very close at being debt free but the principal of our mortgage (I have included everything above 20% in my baby step 2 so I can get rid of PMI quicker). I will keep everyone updated on our progress at meeting this goal.
