How Your FICO Scores are Calculated

There is a lot of misinformation about what goes into your credit score.

However, officials at Fair Isaac Corp. -- the creator of FICO scores -- have said many times that this is the heart of what happens: Your credit files – currently those from Equifax and TransUnion – are reviewed. Certain information (roughly 22 items) about how you've managed your credit is statistically analyzed. Ultimately, five different categories are weighted to produce your FICO score.

Here is the breakdown of those five areas that contribute to your FICO score:


The Formula That Governs Your FICO Score

1. Payment History: Approximately 35% of your score is based on this category.
2. Amounts Owed: About 30% of your score is based on this category. (Mainly, you're evaluated based on how much credit card debt you have).
3. Length of Credit History: Roughly 15% of your score is based on this category.
4. New Credit or Inquiries: Around 10% of your score is based on this category.
5. Types of Credit in Use: About 10% of your credit score is based on this category. (Having a good mix of credit in your credit files is viewed favorably, although some forms of debt, such as mortgage debt, is scored more positively than other forms of debt, like department-store cards or furniture-store cards).

Based on this information, as well as other advice FICO freely disseminates on its Web site (www.myfico.com) and elsewhere, you can draw some good general conclusions about what actions can help your credit – and what could hurt it. For example, to increase your credit scores:

Pay Your Bills on Time

* Payment track record is the largest component of your FICO score.
* Even if you must make "minimum" payments, do it!
* One late payment can drop your FICO score by 60 to 110 points.

Maintain Low Credit Card Balances

* Don't "max out" any cards.
* Try to not to use up too much of your available credit limit.
* Spread out debt over several cards instead of carrying big balances.

Keep Your Older, Established Accounts Open

* Longer credit history is scored favorably.
* Resist the urge to close an account when you pay it off.
* Closing accounts can sometimes lower your FICO credit scores.

Remember these facts the next time you're tempted to do something that might damage your credit rating.
