Credit utilization, a critical factor in credit scoring, plays a significant role in determining an individual's creditworthiness. When it comes to authorized users, understanding the implications of credit utilization is crucial, as it can influence their credit profile. In this article, we'll explore what credit utilization is, its importance in credit scoring, and how it affects authorized users.

Credit Utilization Defined:

Credit utilization is the ratio of a person's credit card balances to their credit limits. It is expressed as a percentage and is a key component of credit scoring algorithms. Lenders use this metric to assess an individual's ability to manage credit responsibly. The formula is simple: divide the total credit card balances by the total credit card limits and multiply by 100 to get the percentage.

The Impact on Credit Scores:

  1. High Credit Utilization:

    • A high credit utilization ratio, meaning a significant portion of available credit is being used, can negatively impact credit scores.
    • Credit scoring models generally consider lower credit utilization as a positive indicator of financial responsibility.
  2. Low Credit Utilization:

    • Conversely, maintaining a low credit utilization ratio can have a positive impact on credit scores.
    • Lenders often view individuals with lower utilization as less risky, as it suggests responsible credit management.

Credit Utilization and Authorized Users:

  1. What are Authorized Users?

    • Authorized users are individuals who are granted permission to use someone else's credit card account.
    • This arrangement is common among family members, spouses, or individuals seeking to build or improve their credit history.
  2. How Credit Utilization Affects Authorized Users:

    • Authorized users inherit the primary cardholder's credit history, including the credit utilization on the shared account.
    • If the primary cardholder has a high credit utilization ratio, it can potentially impact the credit scores of authorized users.
  3. Strategies to Minimize Impact:

    • Communication is key. Before becoming an authorized user, discuss credit utilization habits with the primary cardholder.
    • Encourage the primary cardholder to maintain a low credit utilization ratio to benefit both parties.
  4. Monitoring and Mitigating Impact:

    • Regularly check credit reports to ensure accuracy and monitor any changes in credit utilization.
    • If credit utilization becomes a concern, authorized users can request removal from the account to prevent further impact on their credit.


Credit utilization is a critical aspect of credit health that extends to authorized users. While being added as an authorized user can be a strategic move to build or improve credit, it's essential for both parties to be mindful of credit utilization practices. Open communication, responsible credit management, and periodic monitoring can help authorized users navigate the potential impact on their credit scores and make informed decisions about their financial well-being.
