There are several important things to remember about responsible credit card use, but most importantly pay at least the minimum amount due each month by the payment due date. Late payments are one of the biggest reasons a person’s credit score goes down.

Other important guidelines include:

  • Only charge as much to your credit card as you can easily afford to pay off each month.
  • Keep your balance below your credit limit; try to spend less than 30% of your available credit.
  • Do not apply for too many credit cards at once – only apply for as much credit as you can afford to pay off.

Missing payments, going over the credit limit, opening too many credit accounts, and spending more than they can afford are the most common ways people to get into trouble with credit cards.
