Credit Score
A three-digit number, typically 300 to 850, that lenders use to estimate how likely you are to repay borrowed money.
What Credit Score means
A credit score condenses your credit report into a single number predicting repayment risk. Higher is better; most lenders treat 740 and above as excellent and below 580 as poor.
The dominant inputs are payment history and how much of your available credit you are using. Length of credit history, mix of account types, and recent applications for new credit make up the rest.
Your score determines not just whether you are approved but what you pay. The rate spread between excellent and fair credit on a 30-year mortgage routinely exceeds a full percentage point — tens of thousands of dollars over the life of the loan.
You have more than one score. Different bureaus hold slightly different data and different scoring models weigh it differently, so the number varies depending on who is asking.
