The Short Answer
Key takeaway: FICO 9 considers rental payments and lessens the impact of unpaid medical bills, unlike FICO 8, which remains the most widely used model for credit card approvals.
FICO 8 and FICO 9 are both credit scoring models used to evaluate creditworthiness, but they handle certain financial behaviors differently. FICO 9, for instance, gives less weight to unpaid medical bills and more accurately reflects rental payment history, potentially benefiting individuals with these specific financial patterns. Meanwhile, FICO 8 remains the most widely used model, particularly for credit card approvals. Understanding the differences can help individuals manage their credit profiles more effectively.
What People Get Wrong
A common misconception is that FICO 9 is universally better for everyone. While it might benefit certain financial situations, it is not universally superior. Many think that switching to FICO 9 will automatically improve their credit score. However, changes only apply if lenders adopt the newer model, and many still rely on FICO 8. It's also misunderstood that all types of debts are treated equally across versions, which affects how scores are calculated.
What Really Affects It
FICO 8 and FICO 9 assess creditworthiness using similar criteria, such as payment history, credit utilization, length of credit history, new credit, and credit mix. However, FICO 9 does not penalize consumers as heavily for unpaid medical collections and weighs rental history more significantly, offering a more comprehensive view of financial health. Both models emphasize the importance of maintaining low credit utilization—ideally below 30%—and making timely payments across all accounts.
Signs You Are on Track
Key takeaway: If your credit utilization is below 30%, you're likely on track. FICO 9 may favor you if unpaid medical bills are minimal and rent payments are reported.
If your credit habits align well with both FICO 8 and FICO 9 criteria, you are likely on track. Consistently paying bills on time, keeping credit utilization low, and having a diverse credit mix are positive indicators. If you have unpaid medical bills, FICO 9 may reflect your score more favorably. Additionally, if you’re renting and your landlord reports payments to credit bureaus, FICO 9 might boost your score more than FICO 8 will.
Questions Worth Asking First
Before deciding which credit scoring model to focus on, ask yourself who is using your credit score. Are potential lenders or landlords relying on FICO 8 or FICO 9? Consider whether you have unpaid medical bills or consistent rent payments that could impact your score differently between the two models. Assess whether improving aspects of your financial profile that are emphasized more in FICO 9 is practical for your situation and financial behavior.
When It Makes Sense to Act
Key takeaway: Act when facing a major financial decision. If a lender uses FICO 9, report rental payments and address medical debts. For FICO 8, focus on reducing debt and timely payments.
Acting makes sense when a major financial decision is on the horizon, such as applying for a mortgage or car loan. Knowing which model the lender uses—FICO 8 or FICO 9—can guide your strategy. If FICO 9 is used, ensuring your rental payments are reported or addressing medical debts can be more beneficial. Conversely, if FICO 8 is in play, focusing on reducing overall debt and ensuring timely payments is crucial.
