What is Credit Scoring?
Credit scoring is a system creditors use to help determine whether
to give 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, credit scoring has been used
to help creditors evaluate your ability to repay home mortgage loans.
Here's how credit scoring works in helping decide who gets credit
-- and why.
Information about you and your credit experiences, such as your
bill-paying history, the number and type of accounts you have, late
payments, collection actions, outstanding debt, and the age of your
accounts, is collected from your credit application and your credit
report. Using a statistical program, creditors compare this information
to the credit performance of consumers with similar profiles. A
credit scoring system awards points for each factor that helps predict
who is most likely to repay a debt. A total number of points --
a credit score -- helps predict how creditworthy you are, that is,
how likely it is that you will repay a loan and make the payments
when due.
Because your credit report is an important part of many credit
scoring systems, it is very important to make sure it's accurate
before you submit a credit application.
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 applicants objectively. Judgmental methods typically rely on
criteria that are not systematically tested and can vary when applied
by different individuals.
How is a credit scoring model developed?
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 credit scoring model, different
scoring models for different types of credit, or a generic model
developed by a credit scoring company.
Under the Equal Credit Opportunity Act, a credit scoring system
may not use certain characteristics like -- race, sex, marital status,
national origin, or religion -- as factors. However, creditors are
allowed to use age in properly designed scoring systems. But any
scoring system that includes age must give equal treatment to elderly
applicants.
