How FICO Credit Scores Are Calculated

Since our society is so automated, it's probably not that surprising that your ability to repay your mortgage loan comes down to a single number. The FICO score is built by credit reporting agencies. These agencies use the payment history of all of your loans: credit cards, mortgages, car/boat loans and others.

All three credit reporting agencies (Equifax, Experian and TransUnion) use a slightly different system to arrive at a credit score. The original FICO model was developed by Fair Isaac and Company. While Experian still calls its score "FICO", TransUnion calls its score "Beacon" and Equifax uses "Empirica." While the formulas vary, the differences aren't huge; they all use the following in calculating a credit score:

  • Credit History - How long have you had credit?
  • Late Payments - Do you pay your bills on time?
  • Credit Card Balances - How many accounts? How much do you owe?
  • Credit Inquiries - How many times have you had your credit checked for a loan?

These factors are weighted a little bit differently depending on which formula the agency uses. The results are added up and distilled into a single number. FICO scores range from 300 to 800. Higher is better. Most home buyers have a score above 620.

Not just for qualifying

Did you know? FICO scores affect more than your ability to get a loan. They also affect your interest rate. Higher scores indicate you are probably a better credit risk, and thus may qualify for a better mortgage rate.

Improving your score

What can you do to raise your FICO score? Very little in the short term. Some companies promise quick fixes, but they can't do anything different than what you can do — for free. (Of course you must appeal incorrect items on your credit report.)

Know your FICO score

Before you can improve your FICO score, you have to obtain your score and make sure that the reports from each credit reporting agency are correct. Fair Isaac has created a web site (www.myFICO.com) that lets you do just that. For a reasonable fee, you can quickly get your FICO from all three agencies, along with your credit report. They also provide information and online tools that help you improve your credit score.

You can get a free credit report every year from the three major credit reporting agencies at AnnualCreditReport.com. You won't get a free credit score from AnnualCreditReport.com, but getting it is fast and very inexpensive.

Now that you have all the facts, you'll be a more informed consumer and you'll be better positioned to get the most favorable mortgage.
