Your credit score gives lenders a sense of your debt-repayment history. Although different models are used to calculate your score, they all take the same financial behaviour into account. Your credit score is calculated based on your payment history, the amount of money you owe, the length of your credit history, the type of credit you have, and the new credit that has been added. A change in your score means one of those factors has changed.
