What is Credit Scoring?
Credit scoring is a statistical analysis performed by lenders and financial institutions to access a person's creditworthiness. Credit scoring is used by lenders to help decide on whether to extend or deny credit. A person's credit score is a number between 300 and 850, 850 being the highest credit rating possible. A credit score can impact many financial transactions including mortgages, auto loans, credit cards, and private loans.
A credit score is influenced by five categories—payment history, types of credit, new credit, current debt and length of credit. A person needs to pay special attention to current debt and payment history.

How Credit Scoring Works
Credit scoring models may differ slightly in how they score credit. Fair Isaac Corporation's credit scoring system, known as a FICO score, is the most widely used credit scoring system in the financial industry. However, another popular credit scoring model is VantageScore, which was created by the three credit-reporting agencies—TransUnion, Experian, and Equifax.
- Credit scores determine a person’s ability to borrow money for mortgages, auto loans, and even private loans for college.
- VantageScore and FICO are both popular credit-scoring models.
- Lenders use credit scoring in risk-based pricing in which the terms of a loan, including the interest rate, offered to borrowers are based on the probability of repayment.
- Credit rankings apply to companies (business) and governments and credit scoring applies to individuals.

Credit Scoring vs. Credit Rating
A similar concept, credit ratings, should not be confused with credit scoring. Credit ratings apply to companies, sovereigns, sub-sovereigns and those entities' securities, as well as asset-backed securities.
As a traditional approach to credit risk analysis, credit scoring is most effective for small owner-operated businesses and individuals.
Credit scoring models make up a picture of your relationship with credit and scores will vary (although usually not drastically change) between the three main credit bureaus.
A credit rating determines both the interest rate for the repayment and if the borrower will be approved for a loan of credit or debt issue.
Although credit scoring ranks a borrower's credit riskiness, it does not provide an estimate of a borrower's default probability. As an ordinal ranking, it only assesses a borrower's riskiness from highest to lowest. As such, credit scoring suffers from its inability to determine whether Borrower A is twice as risky as Borrower B.
Another interesting limit to credit scoring is its inability to explicitly factor in current economic conditions. For instance, if Borrower A has a credit score of 800 and the economy enters a recession, Borrower A's credit score would not adjust unless Borrower A's behavior of financial position changed.
More advanced methods of credit risk modeling include structural models and reduced-form models.
