My husband and I are approaching a small financial crossroads. We make his final graduate school payment in June, he graduates in August, and that will bring a small automatic raise (about $1000 a school year minimum). That means that we will have an extra $750 a month starting in August. We’re wondering what we should do with it since we have several options. I know, it’s a good problem to have, but I have a personal finance blog for a reason (I over-think money)…

Here’s the info we’re working with:

• We’re in our mid-20s and want to retire at age 52.
• Our current emergency fund has 3-4 months of expenses in it and our jobs are VERY stable.
• Our mortgage has about $73,300 left at 5.375% and is already on track to be paid off by the end of 2017 instead of 2022.
• Hubby’s car loan has about $10,700 left at 4.6% and is already on track to be paid off by the end of 2011 instead of 2013.
• We contribute 6% to my 401k, which is matched up to 6%.
• We fully fund one Roth IRA ($5000 a year).
• We put about $200 a month into our Scottrade account.
• We put $250 a month into our vacation account.
• We each get $75 a month in “fun” money.
• We also put $200 a month into a home and auto maintenance account.

Mr. BFS and I agree on a couple of things and are wondering about a few other options, so he suggested I ask you. What would you do with an extra $750 a month in our position? Do you need to know anything else in order to decide?
