Why Would My Credit Score Suddenly Decrease?

A credit score numerically represents an individual’s creditworthiness, assessing the likelihood a borrower will repay debts. Understanding the factors that influence this score is important for financial health, as a lower score can affect access to loans, interest rates, and even housing or employment opportunities. This article explores common reasons why a credit score might experience a sudden decrease, ranging from routine payment habits to significant financial events and potential data inaccuracies.

Payment Behavior

Payment history is a primary component of credit scoring models. Any deviation from consistent on-time payments can lead to a significant decline. A payment marked as 30 days late can cause a noticeable drop in a credit score, with the impact becoming more severe if the payment becomes 60 or 90 days past due. Lenders typically report these delinquencies to credit bureaus once they are at least 30 days overdue. Even a single late payment can substantially lower a score.

Completely missed payments or defaulting on a loan cause severe damage to a credit score. The negative mark from a missed payment can remain on a credit report for up to seven years from the date the account was first reported delinquent, although its impact on the score diminishes over time. If an account remains unpaid for an extended period, it may be sent to collections.

When an account goes to collections, it means the original creditor has sold or assigned the debt. The appearance of a collection account on a credit report can cause a substantial credit score drop. These accounts can remain on a credit report for up to seven years from the date of the original delinquency. While some newer models may ignore paid collection accounts, many commonly used models still consider them detrimental.

Credit Usage

The amount of credit an individual uses relative to their available credit, known as the credit utilization ratio, significantly influences credit scores. A high credit utilization ratio signals increased risk to lenders, often leading to a credit score decrease. Financial experts generally advise keeping this ratio below 30% to maintain a good credit score.

Maxing out credit cards can severely hurt a credit score. When a card is maxed out, its utilization jumps to 100%. This indicates that an individual might be struggling financially and relying heavily on credit. Even if payments are made on time, high utilization alone can lead to a significant score drop.

While increasing balances on revolving accounts, like credit cards, typically have an immediate and pronounced negative impact, increasing balances on installment loans are generally viewed differently. Installment loan balances are often part of a planned debt repayment schedule and do not reflect the same level of utilization risk as revolving credit. However, a high overall debt burden can still be a factor in credit evaluations, even if the utilization ratio on revolving credit remains low.

New Credit Applications

Applying for new credit can lead to a temporary decrease in a credit score due to a “hard inquiry” on the credit report. A hard inquiry occurs when a lender formally requests to view an individual’s credit report as part of a loan or credit card application process. Each hard inquiry can cause a small, temporary dip in the score.

Hard inquiries remain on a credit report for up to two years, though their impact on the credit score generally diminishes after 12 months. Multiple hard inquiries within a short period can have a compounding negative effect, signaling to lenders that an individual may be in financial distress or attempting to acquire too much credit. However, credit scoring models often account for “rate shopping” for specific types of loans, such as mortgages or auto loans, by counting multiple inquiries within a specific timeframe as a single inquiry. This allowance typically does not apply to credit card applications.

Opening a new credit account can also affect a credit score by lowering the average age of an individual’s credit accounts. A longer credit history contributes positively to a credit score. A new account, being very young, can reduce this average age. While the initial impact is often slight, managing the new account responsibly over time can help to rebuild and eventually improve the score.

Major Financial Events and Errors

Certain major financial events can lead to severe and prolonged decreases in a credit score. Public record events, such as bankruptcy, foreclosure, or tax liens, are considered highly detrimental. A bankruptcy can remain on a credit report for up to 10 years, making it significantly more challenging to obtain new credit. Foreclosures and tax liens also have a lasting negative impact, signaling a severe inability to meet financial obligations.

Charge-offs occur when a creditor determines a debt is unlikely to be collected and writes it off as a loss. While the creditor considers the debt a loss, the borrower remains legally obligated to repay it. A charge-off can significantly damage a credit score and stay on the credit report for seven years from the date of the original delinquency. Similarly, settling an account for less than the full amount owed, known as debt settlement, also negatively affects a score. This is because it indicates the original terms were not met, and the account is marked as “settled” rather than “paid in full,” remaining on the report for seven years.

Beyond personal financial missteps, external factors like credit report errors or identity theft can also drastically lower a credit score. Inaccurate information on a credit report can unfairly depress a score. It is important to regularly review credit reports from the major credit bureaus for such discrepancies and dispute any errors found. Identity theft can lead to new, fraudulent accounts being opened or unauthorized charges appearing on existing accounts. These fraudulent activities can quickly accumulate unpaid debts and hard inquiries, severely damaging the credit score, so prompt action to resolve identity theft is crucial to mitigate its impact.
