Credit ratings vary from a scoring model to another, but in general the FICO scoring system is the standard in U.S., Canada and other global areas. The factors are similar and may include:
Payment history (35% contribution on the FICO scale) - A record of negative information can lower a consumer's credit rating or score. In general risk scoring systems look for any of the following negative events; charge offs, collections, late payments, repossessions, foreclosures, settlements, bankruptcies, liens, and judgements. Within this category FICO considers the severity of the negative item, the age of the negative items and the prevalence of negative items. Newer is worse than older. More severe is worse than less severe. And, many is worse than few.
Debt (30% contribution on the FICO score) - This category considers the amount and type of debt carried by a consumer as reflected on their credit reports. There are three types of debt considered.
Revolving debt - This is credit card debt, retail card debt and some petroleum cards. And while home equity lines of credit have revolving terms the bulk of debt considered is true unsecured revolving debt incurred on plastic. The most important measurement from this category is called "Revolving Utilization", which is the relationship between the consumer's aggregate credit card balances and the available credit card limits, also called "open to buy." This is expressed as a percentage and is calculated by dividing the aggregate credit card balances by the aggregate credit limits and multiplying the result by 100, thus yielding the utilization percentage. The higher that percentage the lower your score will likely be. This is why closing credit cards is generally not a good idea for someone trying to improve their credit scores. Closing one or more credit card accounts will reduce your total available credit limits and likely increase the utilization percentage unless the cardholder reduces their balances at the same pace.
Installment debt - This is debt where there is a fixed payment for a fixed period of time. An auto loan is a good example as you're generally making the same payment for 36, 48, or 60 months. While installment debt is considered in risk scoring systems it is a distant second in its important behind the revolving credit card debt. Installment debt is generally secured by an asset like a car, home, or boat. As such, consumers will use extraordinary efforts to make their payments so their asset isn't repossessed by the lender for non-payment.
Open debt - This is the least common type of debt. This is debt that must be paid in full each month. An example is any one of the variety of credit cards that are "pay in full" products. The American Express Green card is a common example. Open debt is treated like revolving credit card debt in older version of the FICO scoring system but is excluded from the revolving utilization calculation in newer versions.
Time in file (Credit File Age) (15% contribution on the FICO scale) - The older your credit report the more stable it is, in general. As such, your score should benefit from an old credit report. This "age" is determined two ways; the age of your credit file and the average age of the accounts on your credit file. The age of your credit file is determined by the oldest account's "date opened", which sets the age of the credit file. The average age is set by averaging the age of every account on the credit report, whether open or closed.
Account Diversity (10% contribution on the FICO scale) - Your credit score will benefit by having a diverse set of account types on your credit file. Having experience across multiple account types (installment, revolving, auto, mortgage, cards, etc.) is generally a good thing for your scores because you're proving the ability to manage different account types.
The Search for New Credit (Credit inquiries) (10% contribution on the FICO scale) – An inquiry is noted every time a company requests some information from a consumer's credit file. There are several kinds of inquiries that may or may not affect one's credit score. Inquiries that have no effect on the creditworthiness of a consumer (also known as "soft inquiries"), which remain on your credit reports for 6 months and are never visible to lenders or credit scoring models, are:
Prescreening inquiries where a credit bureau may sell a person's contact information to an institution that issues credit cards, loans and insurance based on certain criteria that the lender has established.
A creditor also checks its customers' credit files periodically. This is referred to as Account Management, Account Maintenance or Account Review.
A credit counseling agency, with the client's permission, can obtain a client's credit report with no adverse action.
A consumer can check his or her own credit report without impacting creditworthiness. This is referred to as a "consumer disclosure" inquiry.
Employment screening inquiries
Insurance related inquiries
Utility related inquiries
Inquiries that can have an effect on the creditworthiness of a consumer, and are visible to lenders and credit scoring models, (also known as "hard inquiries") are made by lenders when consumers are seeking credit or a loan, in connection with permissible purpose. Lenders, when granted a permissible purpose, as defined by the Fair Credit Reporting Act, can "pull" a consumer file for the purposes of extending credit to a consumer. Hard inquiries can, but don't always, affect the borrower's credit score. Keeping credit inquiries to a minimum can help a person's credit rating. A lender may perceive many inquiries over a short period of time on a person's report as a signal that the person is in financial difficulty, and may consider that person a poor credit risk.
