<prompt> Human: Hi everyone,I have about 5k of student loans leftover right now and two credit cards; one of them is a Mileage card and the other is cashback.I was wondering: if I could use one of my credit cards instead of my debit card to pay for loans and investments roth, wouldnt I technically be getting more rewards from the same amount of money? Is there any reason why I shouldnt be using my credit cards to pay my bills?I have the means to pay off the credit cards full every month.I am also pretty new to saving and budgeting so bear with me if I am talking some beginner nonsense.  <response>: Almost all student loan providers wont allow you to pay off loans with a credit card.
