Your credit score matters when applying for a new home loan. It impacts the types of loans and terms you qualify for. However, navigating your FICO score while knowing what Equifax, TransUnion & Experian do is complex.

Are FICO, Equifax, TransUnion & Experian the Same?

No. In fact, FICO performs one role while Equifax, Experian & TransUnion have another regarding your credit score. While the terms are used interchangeably and largely seen as synonymous the truth is they couldn’t be further from being mirror images of one another.

Aside from determining your rarely used Vantage credit score, Equifax, TransUnion and Experian have nothing to do with calculating your credit score while FICO has everything to do with it.

What Equifax, TransUnion & Experian Do

The role the 3 credit bureaus play surprises most. In fact, while having nothing to do with calculating your numerical credit score – Equifax, Experian & TransUnion do largely factor in to your credit score.

Equifax, Experian & TransUnion provide data to your credit report. In other words, each reports info about your credit habits and history to your credit report. For example, the data they report includes:

  • name of creditors you pay
  • your on time & late payment history
  • balances owed
  • monthly payment amounts
  • collections/judgments & public records

What Does FICO do?

On the other side of this numerical credit score union, FICO’s role is to provide the advanced algorithm responsible for crunching data from the big 3 into your actual numerical credit score. It’s that simple – Equifax, Experian & TransUnion provide data and FICO calculates that data into your credit score for each bureau.

50 + Different FICO Score Models

FICO is short for Fair Issacs Corporation. FICO is a company that (among many other products) produces credit score calculations used to determine your credit score. In fact, to date FICO owns over 50 credit scoring models used worldwide. These 50+ scoring models each potentially crunch the data provided by Equifax, Experian & TransUnion into a different numerical credit score for you.

While it sounds complex, the truth is having 50+ different credit score models makes the lending world a better place. In short, having multiple variations of tailor fit FICO credit score models helps lenders make prudent lending decisions.

Credit Data + FICO Calc = Credit Score

In conclusion, FICO, Equifax, Experian and TransUnion combine to create the credit scores your mortgage lender sees. The big 3 feed data about you into a fancy calculation created by FICO. The end result is your credit score.

A simple way to look at this whole concept is this – there are 2 ways to say what credit score your lender used:

  1. “my FICO score is 740”

2. “The credit score that my mortgage lender used was the middle score of 3 credit scores that were determined by analyzing data Equifax, Experian and TransUnion provided to a version of a FICO credit scoring algorithm created by a company called Fair Issacs Corporation specifically for the mortgage industry.”

Safe to say option 1 is the better choice. However, option 2 tells the whole story.
