When you use a credit card you should always try to pay off as much as the balance each month as possible to have a great credit score.
Paying only the minimum is okay but paying more than the minimum is much better at getting your credit score to raise.
Whenever you use your credit card you should pay off at least half the balance each month if you're unable to pay off the full amount of the balance.
Paying more than the minimum payment each month on a credit card will help to improve your credit score in time.
