<prompt> Human: Im a 23 year old, accountant. After I pay all my fixed costs for the month I usually have about 500 dollars left over. I have a mutual fund with about 15k, I just started my Roth IRA, and I also put about 200 dollars a month into a 90 stock 10 bonds investment account. I pay 300 dollars in student loans a month. I owe about 27k overall. No cc debt. I have 7k in an emergency fund. Im not sure what to do with the extra 400-500 dollars. Thanks. Any advice would be great.  <response>: Put it on your student loans.
