Why It's So Important:



Ever wonder how a creditor 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 and auto loans. More recently, scoring has been used to help creditors evaluate your ability to repay home mortgage loans.

Precisely what is credit scoring?

Credit scoring is a system creditors use to help determine whether to give you credit. Information about you and your credit experiences, such as bill-paying history, the number and type of accounts you have, late payments, collection actions, outstanding debt, and age of your accounts is collected from credit applications and your credit report.

Using a statistical program, creditors compare this information to the credit performance of consumers with similar profiles. A scoring system awards points for each factor that helps predict who is most likely to repay a debt. Total number of points helps predict how creditworthy you are; how likely it is that you will repay a loan and make payments when due.

Why is credit scoring used?

Credit scoring is based on real data and statistics, so it usually is more reliable than subjective or judgmental methods. It treats all applications objectively. Judgmental methods typically rely on criteria that are not systematically tested and can vary when applied by different individuals.

To develop a model, a creditor selects a random sample of its customers (or a sample of similar customers if their sample is not large enough), and analyzes it statistically to identify characteristics that relate to creditworthiness. Then, each of these factors is assigned a weight based on how strong a predictor it is of who would be a good credit risk.

Each creditor may use its own scoring model, different scoring models for different types of credit, or a generic model developed by a credit scoring company.

How reliable is the credit scoring system?

Credit scoring systems enable creditors to evaluate millions of applicants consistently and impartially on many different characteristics. But to be statistically valid, scoring systems must be based on a big enough sample. Remember that these systems generally very from creditor to creditor.

Although you may think such a system is arbitrary or impersonal, it can help make decisions faster, more accurately, and more impartially than individuals when it is properly designed.

In fact, many creditors design their systems so that, in marginal cases, applicants whose scores are not high enough to pass easily, or are low enough to fail absolutely are referred to a credit manager who decides whether the company or lender will extend credit. This may allow for discussion and negotiation between the credit manager and the consumer.
