Lenders use a number of different credit score programs to determine what kind of risk you are. The best known credit score program is FICO credit score (which was created by Fair Isaac). However, there really are multiple versions of FICO and each can yield a different credit score for the same person. In addition to FICO there is CreditXpert, programs created by individual lenders, and even scoring systems that have been created by the credit reporting agencies themselves.
All of these systems can be used to predict your creditworthiness and they all run off the same point basis. The scale generally runs with a credit score from the mid-300s to a credit score with the mid-800s. Your numbers may vary by up to 60 points from one scoring program to another but your credit score should remain in roughly the same range.
Slight variations in your credit score are caused by two factors
The Formula Used
Each credit scoring program uses its own weighting system on primarily the same data that all companies use. In other words, one company may weigh late payments into the credit score more heavily than other companies might. In addition, some companies have specific formulas for the type of credit being sought. So, if you are applying for a mortgage, the credit score may be different than if you were applying for a car loan. This is, again, due to the amount of weight the scoring program gives various aspects of your credit record.
Different Data
There are three different credit bureaus that maintain credit records and each different credit bureau typically has different information in your records. This is often caused by the different information that the bureaus receive from creditors and the time frame in which they receive it. So, if your credit score was compiled based on your Equifax credit report it may vary considerably from a credit score compiled from your Experian credit report. For this reason, most lenders use the middle of the three bureau credit scores when making decisions, especially for mortgage lending.
If your credit score varies more widely than 60 points, check your credit reports and make sure there are no errors. Often an error can occur in one of your reports, causing your credit score to be completely different. But one thing is certain. Your credit score is very important.
