Your credit score is a number between 350 - 850 on a scale created by the Fair Isaac Corporation (FICO). This number is known as your FICO® score, and it is used by lenders as a snapshot of your credit history and a summary of risk involved to lending to you. The score is calculated based on an analysis of a person's credit history and files.
The higher the credit score, the lower the risk to the lender and generally means a lower interest rate to you as a borrower. A lower credit score equates to more potential risk to lenders and generally higher interest rates to you as a borrower.
