Your credit score is one of the most important numbers in your financial life, yet it's also one of the most misunderstood. In 2026, credit scores influence everything from credit card approvals and interest rates to auto loans, mortgages, rental applications, and even insurance pricing in some regions.
This guide explains how credit scores actually work, what impacts them the most, and how you can use that knowledge to build and protect strong credit over time.
What Is a Credit Score?
A credit score is a three-digit number designed to predict how likely you are to repay borrowed money on time. Lenders use it to assess risk before approving credit or setting interest rates.
In the United States, most lenders rely on FICO® Scores, which range from 300 to 850. Higher scores signal lower risk and generally lead to better loan terms.
According to FICO, scores typically fall into these ranges:
- Excellent:800–850
- Very Good:740–799
- Good:670–739
- Fair:580–669
- Poor:Below 580

The 5 Main Factors That Determine Your Credit Score
Credit scoring models use five core factors. Understanding these is the key to improving your score.
1. Payment History (35%)
Payment history is the most important factor. It tracks whether you pay your credit accounts on time.
Late payments, collections, defaults, and charge-offs can severely hurt your score. On the other hand, consistent on-time payments build positive history over months and years. Even one missed payment can stay on your credit report for up to seven years, according to Experian.
Pro Tip: Set up automatic payments for at least the minimum amount to ensure you never miss a due date.
2. Credit Utilization (30%)
Credit utilization measures how much of your available credit you're using.
Example:
- • Total credit limit: $12,000
- • Current balances: $3,000
- • Utilization rate: 25%
Most credit experts recommend keeping utilization below 30%, and under 10% for the best scores. High utilization signals financial stress to lenders, even if you pay on time.
The Consumer Financial Protection Bureau (CFPB) confirms that utilization is a major predictor of credit risk.
3. Length of Credit History (15%)
This factor looks at:
- How long your oldest account has been open
- The average age of all your accounts
This is why closing old credit cards can sometimes hurt your score. A longer history gives lenders more data to assess your behavior. Learn more about the longevity rule and credit account age.
4. Credit Mix (10%)
Credit mix reflects the types of credit you use, such as:
- Credit cards
- Auto loans
- Student loans
- Mortgages
You don't need every type, but managing different forms of credit responsibly can help.
5. New Credit & Inquiries (10%)
Each time you apply for credit, a hard inquiry is added to your report. Too many inquiries in a short period can temporarily lower your score.
Checking your own credit, however, results in a soft inquiry and does not affect your score.

How Often Does Your Credit Score Change?
Your credit score can change monthly or even weekly, depending on when lenders report updates. Paying down balances, opening new accounts, or missing payments can all trigger changes.
In 2026, most major lenders report to credit bureaus at least once per billing cycle.
