Which Credit Score Is the Most Accurate?

If you’ve been thinking about taking out a loan or another form of credit, then you may be wondering which credit score is the most accurate.

But instead of asking which one’s most accurate, it may be helpful to first understand how credit scoring models work. Two primary credit scoring models exist, each measuring your score in slightly different ways.

In this article, we will discuss the different credit scoring models, the criteria that they use to assign your credit score, and some strategies to help you monitor your credit scores effectively.

Based on the information from your credit report, credit scoring models assign you a three-digit number that’s known as your credit score. Different credit scoring models can assign you different credit scores, as they assess information differently.

FICO^® and VantageScore^® are the two most popular credit scoring models today. The credit scores they assign are equally reliable and accurate, based on the specific credit scoring model that’s being used.¹

Scores can and do fluctuate as new data is received. Errors or fraudulent transactions may also negatively impact your score, which could lead to a score that is lower than it should be. However, you can dispute inaccuracies to have the bureaus remove them.

The main reason for different types of credit scores is the existence of multiple credit scoring models.

As we touched on above, there are two primary credit scoring models, FICO and VantageScore. Both credit scoring models may give you a different score because they calculate information differently. Both FICO and VantageScore also release new versions of their credit score models from time to time.

• FICO^® Score
  A FICO is a credit score created by the Fair Issac Corporation. This is a well-known scoring model that’s used for a majority of lending decisions.² There are base FICO^® Scores, that are created for any lender to use, as well as industry-specific FICO Scores, for auto lenders and credit card issuers.


• VantageScore^®
  VantageScore is another credit scoring model. The credit bureaus introduced the VantageScore model in 2006 as a FICO alternative to give credit score access to more people.³

Given the various score types, monitoring yours is crucial. Fortunately, you can request annual credit reports from each bureau and track your score with various online tools.

FICO and VantageScore calculate your score using several factors related to your credit history. They have some factors in common but assign different weights to them.

• How FICO Calculates Your Credit Score
  FICO calculates your score using five factors, which they assign different weights to. While the exact percentages can vary from score to score, here’s a look at the percentages that are generally used in their scoring model:⁴

It’s a good idea to keep an eye on your credit score and credit report. This can help to give you an idea about the type of financing you may be eligible for. Crucially, it can also help you to spot any errors or discrepancies that may be present in your report.
