In this tutorial, we learn how to improve your FICO credit score. Everyone will want to use your credit score to decide what kind of person you are. The FICO is the most commonly used credit score used today. To improve your credit score you will want to make all payments on time. Catch up on past due accounts and utilize 50% and less of your credit limit. Your balance should be under half of what your limit is. Don't close your account, because this can drop your credit score as well. Revolving accounts will also improve your credit score when it shows you make on time payments.
