<prompt> Human: I just received my first credit card and I only have a credit limit of 600. I want to know if it is okay to charge 400 to my credit card pay it off mid-cycle and then charge another 400 on my card and pay it on the due date?  <response>: Short answer: yes.Long answer: A credit card is revolving credit so once you pay off any portion of your balance, that portion is available to use again. When you pay off the 400, that makes the full 600 available again.
