<prompt> Human: So heres a question folks.Ive been told the general rule is you go after the highest interest rate debt first. But what if that interest is tax deductible?I have a line of creditnow locked from when I was a student thats X at 4.0 annually. I have a student loan thats approximately X3 at 8.0 interest. Now my gut reaction is to work down the debt thats not only larger, but at a higher interest rate before working away at the line of credit. But I do get to deduct the interest paid on the student loan against my taxes 15 credit for interest paid, so it seems like theres an incentive to keep it while I work on the LoC.Is there some formula I can plug into excel or something that might show me the interest paid vs tax deferred?  <response>: Pay the 8 loan. Its not close at all, there is no tax situation where the deduction works out as better.
