How FICO Credit Scores Are Calculated

Since we live in an automated society, it should come as no surprise that your ability to repay your mortgage loan comes down to just one number. Credit reporting agencies use your history of paying loans to build a FICO score.

Each of the three credit agencies has its own formula for building your credit score. Fair Isaac and Cooriginally developed this score. . Experian uses this model and calls its score FICO. Equifax's model, based on FICO, is called BEACON, while TransUnion, which also uses a slightly modified FICO, calls its score EMPIRICA. While each of the models considers a range of data available in your credit report, the differences aren't huge; they all use the following factors to calculate a score:

  • Credit History - Have you had credit for many years, or for just a short time?
  • History of Payments - Do you have any payments later than 30 days?
  • Credit Card Balances - How many accounts do you carry? How much do you owe?
  • Credit Inquiries - How many times have lenders pulled your credit report for the purpose of giving you a loan?

These factors are weighted differently depending on the formula being used. The results are added up and distilled into a single number. FICO scores can be as low as 300 and as high as 800. Higher scores are better. Most home buyers have a score above 620.

Your credit score greatly affects how much you pay in interest every month

Did you know? FICO scores are used for more than just determining whether or not you qualify for a mortgage. Higher scores indicate you are a better credit risk, and thus may qualify for a better mortgage rate.

Improving your score

Is there any way to improve your credit score? Despite what you hear from "credit repair" companies, the score is built on your lifelong credit history, so you can't turn it around right away. (Of course you can and should remove incorrect data on your credit report.)

How do I find out my FICO score?

Before you can improve your score, you must obtain your score and make sure that the reports from each agency are correct. Fair Isaac, the corporation that offered the original FICO score, offers credit scores on myFICO.com. It's inexpensive, fast, and easy to get your credit score along with reports from all three reporting agencies. Also available are information and tools that help you analyze what actions might have the greatest impact on your FICO score.

You can get a federally-mandated free credit report once per year from all three credit reporting agencies at AnnualCreditReport.com. These reports do not include a free credit score, but it's very inexpensive to get one at the same time.

Armed with this information, you'll be a more informed consumer and you'll be better positioned to obtain the right mortgage for you.
