Your credit score affects mortgage rates, insurance premiums, and even job offers. Understanding what drives the number -- and what does not -- is the first step toward improving it.
The Five FICO Factors
Your FICO score -- the model used by 90% of lenders -- is calculated from five weighted categories. Understanding each one tells you exactly where to focus your effort.
- Payment history (35%): The single biggest factor. Even one late payment reported to the bureaus can drop your score by 60 to 100 points. Payments 30 or more days past due are reported; anything under 30 days late typically is not.
- Credit utilization (30%): This is the percentage of your available revolving credit you are using. A $3,000 balance on a $10,000 limit equals 30% utilization. Keeping it under 30% is the common advice, but under 10% is what produces the best scores.
- Length of credit history (15%): The age of your oldest account, newest account, and average age of all accounts. This is why closing old cards can hurt your score even if you do not use them.
- Credit mix (10%): Lenders want to see you can handle different types of credit -- revolving accounts (credit cards), installment loans (auto, student, mortgage), and potentially retail accounts. You do not need all types, but having only one can limit your score.
- New credit inquiries (10%): Each hard inquiry (when a lender checks your credit for a lending decision) can lower your score by a few points. Multiple inquiries for the same type of loan within a 14 to 45 day window count as a single inquiry for scoring purposes.
Quick Wins to Raise Your Score
Some strategies produce results within one to two billing cycles. Pay down credit card balances to lower utilization -- this is the fastest lever you can pull. Request a credit limit increase without a hard inquiry (many issuers allow this online), which lowers your utilization ratio instantly. Set up autopay for at least the minimum payment on every account to ensure you never miss a due date.
Check your credit reports at AnnualCreditReport.com for errors. Roughly one in five reports contains a mistake. Dispute inaccuracies directly with the bureau -- incorrect late payments, accounts that are not yours, or wrong balances can all be corrected, sometimes raising your score significantly.
Longer-Term Strategies
If you have thin credit, consider becoming an authorized user on a family member's old, well-managed card. Their payment history and credit limit get added to your report. A secured credit card is another option -- you put down a deposit that becomes your limit and build history with on-time payments.
For those rebuilding after negative marks, know that most derogatory items (late payments, collections, charge-offs) fall off your report after seven years. A Chapter 7 bankruptcy stays for ten years. As these items age, their impact on your score diminishes. Consistent on-time payments during this period gradually rebuild your profile.
Common Myths Debunked
- Checking your own credit hurts your score: False. Pulling your own report is a soft inquiry and has zero impact.
- Carrying a balance improves your score: False. Paying in full each month is better. Interest charges do not help your credit.
- Closing old cards improves your score: Usually the opposite. It reduces available credit (raising utilization) and eventually shortens your credit history.
- Income affects your credit score: Your income is not a factor in FICO scoring at all. A person earning $30,000 can have a higher score than someone earning $300,000.
Bottom Line
Improving your credit score comes down to paying on time, keeping balances low, and being patient with the age of your accounts. There are no shortcuts or magic fixes, but the math is straightforward once you understand the five factors.
