Ever wonder how a lender decides whether to grant you credit? For years, creditors have been using credit scoring systems to determine if you’d be a good risk for credit cards, auto loans, and mortgages. These days, many more types of businesses — including insurance companies and phone companies — are using credit scores to decide whether to approve you for a loan or service and on what terms. Auto and homeowners insurance companies are among the businesses that are using credit scores to help decide if you’d be a good risk for insurance. A higher credit score means you are likely less of a risk, and in turn, means you will be more likely to get credit or insurance — or pay less for it.

The Federal Trade Commission (FTC), the nation’s consumer protection agency, wants you to know how credit scoring works.
