Which Factors Does Fico Use To Calculate Your Score?
In this day in age, where transparency is at a very high level, it may sound very shocking to you, but the formula for the Fico scoring model (a scoring model which is used in 90% of mortgage lending decisions) is still 100% confidential.
Consumers have very little insight into what factors are used to determine their Fico score. Fico only revealed the general 5 big factors which you can read more about here.
The Fair Credit Report Act (section §605(a)(2)) requires lenders to reveal to their consumers,which factors adversely effected their credit score. Therefore, lenders need to know which factors affect a Fico score in order to be able to explain those factors to their consumers.
For this reason, Fico created a list of reasoning codes which credit issuers send along with a denial letter to their consumers, stating the reasons for which their credit score was adversely affected.
In the past, there where blogs which have put together lists of all the reasoning codes which consumers have received, and based on that, you were able to get insight of which factors may adversely affect a credit score. Although this did not give you deep insight into the Fico scoring model, it did help you understand, more generally, which factors Fico will include in calculating the scoring model.
For a quick example, let’s use reasoning code number 10:“Ratio of Balances to Limit On Bank Revolving or Other Revolving Accounts Is to High”. This reasoning code tells you that your score was affected by high balances. It does not tell you, though, which ratio is considered a high balance. 20 percent? 50 percent? 100 percent?
The reasoning codes also only reveal factors which adversely affect credit scores, but there are still many factors which may affect your credit score, but possibly in a more minor way (which wouldn’t have been mentioned in a denial letter).
Recently, a list of the Experian Fico reasoning codes guide was leaked. This document was supposed to be viewed only by credit issuers. It includes a list of all reasoning codes, a full description for all reasoning codes, and it lists actions you can take to improve credit scores. You can view the document here.
