Experian is an international company that calculates credit scores so that lenders can make an informed decision on whether or not to give you credit. These are also commonly known as ‘risk scores', because they help the lender determine what the risk is that they are taking if they afford you the credit. Lenders ask questions such as, “How likely is it that I will be paid back the money on time?” Credit scores are fluid numbers that change often with your updated credit information.

Everything you do that involves credit—your credit cards, personal loans, car loans and mortgage loans, all affect your credit either positively or negatively. If you are late with a payment, it will negatively affect your score. However, if you pay your bills on time and have them all in good standing, this affects your credit score positively. Lenders use a variety of different calculation methods for the scores they give you, which is why your number changes constantly.

Credit scores are affected by the number and severity of late payments, the type, age and number of credit accounts, your total debt and any recent inquiries that ask for your credit score. Credit scores are not affected by any of your personal data, such as age, race or marital status.

Continue to try to improve your credit score. Pay your bills on time and keep your balances low on credit cards and other “revolving credit”. A high outstanding debt can negatively affect your score. You should only apply for credit as you need it and pay off the debts you have rather than moving it around. Owing the same amount and having fewer accounts can actually lower your score.

Keep up to date with your credit score. Experian offers you access to your credit score, which you can view regularly with a nominal fee. You can then watch your Experian credit score's fluctuations and know how you affect your score.
