Your credit score is an actual number, between 300 and 850. The higher the number, the better: a score of 740 to 799 is considered very good, though the average is closer to 700. There are companies responsible for tabulating your credit score and providing the score to potential lenders.
Each of the three main credit agencies – Experian, Equifax, and TransUnion - have a score for you based on your credit report at that individual agency. Each agency has more than 200 million files on people who have a credit history because they have used credit, and 4.5 billion are updated in those files every month. The agencies tend to have different information on the people they track, which means your credit report and score will vary from agency to agency.
Those scores are what potential creditors, landlords, employers and insurers look at for an instant judgment on your creditworthiness.
That’s important because lenders believe that people who are creditworthy will pay back what they owe. That’s why better credit reports and higher credit scores make it easier, and cheaper, to borrow. It also makes it easier to rent an apartment, buy a house, get insurance, and a number of other day-to-day essentials.
