Your credit score is not just a number, it is a tool that you can control and use to save cash. It will become important whenever you need credit and it is an important factor to be considered by any financial organization before they approve your credit application.
Your credit score is determined by statistics from your credit report. Your score is generated at the time your credit report is requested and is not stored as part of the report.
Understanding your credit information will help keep you in control of your finances and help determine how lenders treat you.
