What Credit Score Does and FAQs


Credit scores play a vital role in our financial lives. They are numerical representations of an individual’s creditworthiness, providing lenders and financial institutions with a quick assessment of the borrower’s ability to repay debts. Understanding what credit score does and its impact on our financial health is crucial for making informed financial decisions. This article will delve into the concept of credit scores, how they are calculated, their significance, and answer some frequently asked questions about credit scores.

What is a Credit Score?

A credit score is a three-digit number that reflects an individual’s creditworthiness. It is generated by credit reporting agencies, such as Equifax, Experian, and TransUnion, based on the information found in credit reports. These reports contain detailed information about one’s credit history, including payment history, outstanding debts, length of credit history, types of credit used, and new credit applications.

How is a Credit Score Calculated?

Credit scores are calculated using complex algorithms that analyze various factors from credit reports. The most commonly used scoring model is the FICO score, developed by the Fair Isaac Corporation. FICO scores range from 300 to 850, with higher scores indicating better creditworthiness.

The factors that influence credit scores include:

1. Payment History: Making timely payments on loans, credit cards, and other debts positively impacts credit scores.
2. Credit Utilization: The amount of credit utilized compared to the total available credit affects credit scores. Keeping credit utilization below 30% is generally recommended.
3. Length of Credit History: The longer an individual’s credit history, the more information there is to assess their creditworthiness.
4. Types of Credit Used: A mix of revolving credit (credit cards) and installment loans (mortgages, car loans) can positively impact credit scores.
5. New Credit Applications: Frequent credit applications can negatively impact credit scores, as it suggests a higher level of risk.
