Your credit score is a critical piece of your financial health, yet many of its intricacies are shrouded in mystery. Beyond just making timely payments, there are lesser-known strategies that can have a big impact. Here are five secrets about credit scores that could help you boost yours effectively.

1. Utilization Timing Matters Credit utilization—the amount of credit you use relative to your limit—plays a major role in your score. But did you know timing matters too? Your balance is often reported on the statement closing date, so paying down your balance before this date can improve your utilization rate and potentially give your score a lift. Aim to keep your credit usage below 30% of your limit for optimal results.

2. Credit Mix Counts Diversity in your credit types can positively impact your score. A mix of credit cards, mortgages, and installment loans demonstrates to lenders that you can handle a range of financial responsibilities. If you’ve only ever had credit cards, consider adding another type of credit, like a small installment loan, if it makes sense for your finances.

3. Old Accounts Can Help, Not Hurt While it may seem logical to close unused accounts, keeping them open can actually be beneficial. The average age of your accounts factors into your score, so keeping older accounts open can help improve it. If these accounts don’t have annual fees, consider making occasional small purchases to keep them active.

4. Checking Your Own Score is Safe Many people avoid checking their credit report out of fear it will lower their score. In reality, only “hard inquiries” (from applying for credit) affect your score. Checking your own report, known as a “soft inquiry,” is harmless and a smart habit for monitoring your financial health.

5. Small Errors Can Hurt Big Time Inaccuracies on your credit report—like an incorrect balance or a mistakenly reported late payment—can drag down your score. Regularly reviewing your credit report can help you catch and dispute errors, potentially giving your score a quick boost if issues are corrected.

These lesser-known tips can make a meaningful difference in your credit score, giving you a better foundation for financial success.
