What is the Maximum FICO Score?

When most lenders request your permission to review your credit report and score, they are referring to your FICO score. FICO scores are not the only credit scores available, but lenders depend on the FICO scoring model than any other when assessing lending risks. The Fair Isaac Corporation, which introduced FICO scores in 1958, owns the mathematical formula used to calculate FICO scores. A high FICO score indicates that you are likely to repay your debts and therefore present a low risk for lenders.

Maximum FICO Score

FICO credit scores range from 300 to the maximum credit rating a consumer can have: 850. Very few individuals ever earn a perfect FICO score. A FICO score of 850 is so rare than in 2005 the credit reporting agency TransUnion ran a contest through its TrueCredit credit monitoring service to find individuals with perfect credit scores, awarding each consumer with a FICO score of 850 a check for $1,000.

FICO Score Factors

A variety of information that appears on your credit report can influence your FICO score. The types of accounts you carry, the age of your oldest account, your payment history for current and past creditors and how much you owe all influence your score. A single derogatory item on your credit report, such as a late payment or collection debt, will prevent you from attaining the highest possible FICO score. Consumers with perfect credit have reports that demonstrate low debts, an impeccable payment history and a good balance of credit cards and loans.

Different Scores

The FICO formula uses the financial information present on your credit file to assign you a score. Because of this, your credit score may differ depending on the credit reporting agency that provided the report. Each of the major credit reporting agencies--Experian, Equifax and Transunion--collect information from your creditors but maintain different standards companies must meet before earning the right to file reports. Thus, the information on each of your credit reports will vary depending on which of your creditors report to all three agencies and which report to only one or two. Earning a FICO score of 850 with one credit reporting agency does not guarantee that you also hold a perfect credit score with the other two.


Just because you lack a FICO score of 850, that does not mean that you won’t qualify for low interest rates and other services and benefits that require a high credit rating. Lenders assign interest rates based on credit brackets. Credit brackets differ depending on the lender but, if your credit score falls into the highest bracket, lenders will offer you the same excellent rates that an individual with a maximum FICO of 850 would receive.
