The FICO Score, developed by the Fair Isaac Corporation in 1989, revolutionized how lenders evaluate credit risk in the United States. Before its introduction, credit decisions were often subjective and inconsistent. Today, the FICO Score remains the dominant credit score model used by over 90% of top lenders across the country.

How Your FICO Score Is Calculated

Your FICO Score reflects your credit history and behavior, distilled into one number to help lenders gauge your reliability. It is calculated using five main factors, each weighted differently:

  • Payment History (35%): This is the most influential component. Consistently paying bills on time boosts your score, while late payments, defaults, or collections harm it.
  • Amounts Owed (30%): Known as your credit utilization ratio, this compares your outstanding debt to your total credit limits. Experts recommend keeping utilization below 30% to maintain a healthy score.
  • Length of Credit History (15%): Longer credit histories generally indicate more experience managing credit, helping to increase your score.
  • New Credit (10%): Multiple recent credit inquiries or new accounts can signal increased risk and temporarily lower your score.
  • Credit Mix (10%): A diverse set of credit types, such as credit cards, installment loans, and mortgages, shows that you can manage different borrowing responsibly.

Real-Life Example

Consider Alex and Taylor: Alex pays bills promptly, maintains low credit card balances, and has a credit history spanning 10 years. Taylor, on the other hand, has missed recent payments, maxes out their credit cards, and has just opened their first credit account. Despite similar incomes, Alex will have a significantly higher FICO Score, making loan approval easier and interest rates more favorable.

Who Gets a FICO Score?

Anyone with a credit history reported to the three major credit bureaus—Experian, Equifax, and TransUnion—will have a FICO Score. If you are new to credit, your score may not appear immediately but will build over time with responsible credit use.

Tips to Improve Your FICO Score

  • Always pay on time: Automate payments or set reminders to avoid missed bills.
  • Keep balances low: Aim to use less than 30% of your available credit.
  • Limit new credit applications: Opening several accounts at once can lower your score.
  • Maintain old accounts: Keeping longstanding accounts open lengthens your credit history.
  • Review your credit reports annually: Check for errors at AnnualCreditReport.com and dispute inaccuracies promptly.

Common Misconceptions

  • Checking your own credit does not lower your score—it’s considered a soft inquiry.
  • Closing credit cards can decrease your available credit and potentially hurt your score.
  • Paying off debts doesn’t remove them immediately from your report; they remain for up to seven years but in a paid status.
