Why Is My Credit Score Fluctuating?

A credit score is a three-digit number, typically ranging from 300 to 850, representing an individual’s creditworthiness. Lenders, such as banks and credit card companies, use this score to assess the potential risk of lending money and to determine interest rates and credit limits. It serves as a prediction of how likely someone is to repay a loan on time, based on information from their credit reports. It is not static; it is dynamic and can change frequently, reflecting ongoing financial behavior and activity.

Common Reasons for Credit Score Changes

Credit scores fluctuate due to a variety of factors, as financial actions directly impact them. Payment history is a primary influence, accounting for a significant portion of most credit scores. Consistently making on-time payments across all credit accounts, including credit cards, loans, and mortgages, demonstrates responsible financial management and can lead to an improvement in credit scores over time.

Conversely, late or missed payments can significantly harm a credit score. Even a single payment that is 30 days past due can cause a notable drop, and the negative impact intensifies the longer a payment remains unpaid, with increments often tracked at 30, 60, or 90 days late. These negative marks remain on credit reports for several years, although their impact may lessen over time, particularly if subsequent payments are made on schedule.

Another major factor is credit utilization, which is the amount of credit used relative to the total available credit. This ratio typically accounts for 30% of a FICO Score and 20% of a VantageScore. Maintaining a low credit utilization ratio, generally below 30% of available credit, signals to lenders that an individual is not overly reliant on borrowed funds and can manage debt effectively.

High credit utilization, such as maxing out credit cards, can indicate financial stress and lead to a decrease in scores. Reducing outstanding debt, especially on revolving credit accounts, can quickly improve this ratio and positively impact a credit score. The effect of changes in utilization can be almost immediate once reported to the credit bureaus.

Applying for new credit also influences scores through what are known as hard inquiries. When a lender checks a credit report in response to a credit application, it generates a hard inquiry, which can cause a small, temporary dip of a few points in a credit score. While individual inquiries have a minor impact and typically remain on a report for two years (affecting scores for about 12 months), multiple applications within a short period can have a cumulative negative effect.

The length of credit history and the mix of credit accounts also play a role. A longer credit history, reflecting years of responsible credit management, generally contributes positively to a score. Closing old credit accounts can sometimes negatively impact a score because it reduces the average age of accounts and decreases the total available credit. Having a diverse mix of credit, such as both revolving accounts (like credit cards) and installment loans (like mortgages or auto loans), can demonstrate an ability to manage various types of debt responsibly.

Derogatory marks like bankruptcies, foreclosures, or accounts sent to collections represent severe negative events. These marks can cause significant and long-lasting damage to a credit score, remaining on reports for seven to ten years depending on the type. While their impact lessens over time, they indicate a high level of financial risk to lenders.

Monitoring Your Credit Score

Regularly monitoring both credit reports and credit scores is a practical step for understanding and managing personal financial health. Credit reports provide a detailed history of credit activity, including active accounts, debt levels, and repayment history, forming the foundation upon which credit scores are built. Meanwhile, credit scores offer a numerical summary of creditworthiness derived from this underlying data.

The Fair and Accurate Credit Transactions Act grants consumers the right to obtain a free copy of their credit report every 12 months from each of the three major nationwide credit reporting companies: Equifax, Experian, and TransUnion. These reports can be accessed through the official, federally authorized website, AnnualCreditReport.com. Consumers can choose to request all three reports at once or space them out throughout the year to monitor their credit continuously.

While AnnualCreditReport.com provides free credit reports, it typically does not include credit scores. Many credit card providers, banks, and reputable third-party services now offer free access to credit scores as an added benefit. Utilizing these resources allows individuals to track changes in their scores, which can serve as an early indicator of potential issues or positive trends. Monitoring also helps in identifying any errors or fraudulent activity on a credit report, which could otherwise lead to unexpected score fluctuations.

Understanding Credit Scoring Models

It is common for individuals to observe slight differences in their credit score when checking it through various sources. This variation occurs because there isn’t a single universal credit score; instead, multiple credit scoring models exist. The two most widely used models are FICO Score and VantageScore, each developed by different entities.

While both FICO and VantageScore models utilize similar underlying credit data, such as payment history and amounts owed, they may weigh these factors differently in their algorithms. This can lead to variations in the numerical score presented to a consumer. Furthermore, different versions of these models exist, and lenders may use specific models or versions tailored to the type of credit being sought, such as a mortgage versus an auto loan.

The timing of data reporting by creditors to the three major credit bureaus (Equifax, Experian, and TransUnion) can also contribute to score discrepancies. Not all creditors report to all three bureaus, and reporting schedules can vary, meaning one bureau’s data might be more up-to-date than another’s at any given moment. Despite these potential differences in the exact score number, the core underlying credit data remains consistent across models, and maintaining healthy credit habits will generally result in a favorable score across all models.
