Your credit score is a judgment about your financial health, at a specific point in time. It indicates the risk you represent for lenders, compared with other consumers.
There are many different ways to work out credit scores. The credit-reporting agencies Equifax and TransUnion use a scale from 300 to 900. High scores on this scale are good. The higher your score, the lower the risk for the lender.
Lenders may also have their own ways of arriving at credit scores. In addition, lenders must decide on the lowest score you can have and still borrow money from them. They can also use your score to set the interest rate you will pay.
Credit-reporting agencies and lenders use a mathematical formula to figure out your credit score.
This formula takes into account various factors described in your credit report, such as:
These factors do not all have the same weight in determining your credit score. The most important factors are your payment history, whether you have ever declared bankruptcy, and the amount of your outstanding credit balances.
Although other elements such as your mortgage information and any personal inquiries you have made may also be included in your credit report, they usually do not influence your credit score.

Information that affects your credit score is usually removed from your credit report after a certain period of time. The length of time that information must stay in your report depends on:
