Assuming you have the money to do so, it is almost always better to pay off student loans first. The interest on car loans is typically much lower than the interest on student loans, so paying off your student loans will save you more money in the long run. Additionally, if you are struggling to make your monthly loan payments, you may be able to defer or forbear your student loans, but this is not usually an option with car loans. Therefore, paying off your student loans first will give you more flexibility if you experience financial difficulties in the future.
