 TITLE: How Does Length of Credit History Affect Your Credit? CONTENT: Length or age of credit history refers to the age of the accounts that appear in your credit reports. Credit scoring models use various credit age-related metrics when calculating your score, including:\n*   The average age of your accounts\n*   The age of your oldest account\n*   How long it's been since you opened an account\nAs a general rule of thumb, a longer credit history is better for your credit scores. Additionally, the length of your credit history can impact the relative importance of other scoring factors—as scoring factors can be interdependent.\nThe credit scoring models get all this information by analyzing your credit reports from the three national credit reporting companies (Experian, TransUnion and Equifax). If you get your free credit report from Experian, we automatically calculate and show you the average age of accounts and the age of your oldest account. END
