What Is a Credit Score?
A credit score is a three-digit number — typically ranging from 300 to 850 — that represents your creditworthiness. Lenders use it to assess how likely you are to repay borrowed money. The higher your score, the more confident lenders are in lending to you, which translates to better interest rates and loan approvals.
The most widely used scoring model in the U.S. is the FICO Score, though VantageScore is also common. Both use similar factors but weight them slightly differently.
Credit Score Ranges at a Glance
| Score Range | Rating | What It Means |
|---|---|---|
| 800 – 850 | Exceptional | Best rates, easy approvals |
| 740 – 799 | Very Good | Above-average rates |
| 670 – 739 | Good | Near-average or standard rates |
| 580 – 669 | Fair | Higher rates, some rejections |
| 300 – 579 | Poor | Very limited credit access |
What Makes Up Your Credit Score?
FICO scores are calculated from five factors, each weighted differently:
1. Payment History — 35%
This is the single biggest factor. It tracks whether you've paid your bills on time. Even one missed payment can cause a noticeable score drop. Late payments stay on your credit report for up to seven years, though their impact diminishes over time.
2. Credit Utilization — 30%
This is how much of your available credit you're currently using. If you have a $10,000 credit limit and carry a $3,000 balance, your utilization is 30%. Keeping utilization below 30% is generally recommended; below 10% is even better for top scores.
3. Length of Credit History — 15%
The longer your accounts have been open, the better. This is why closing old credit cards — even ones you don't use — can hurt your score by reducing average account age.
4. Credit Mix — 10%
Having a variety of credit types (credit cards, auto loans, mortgage, student loans) shows lenders you can manage different kinds of debt. You don't need every type — just don't avoid credit entirely.
5. New Credit Inquiries — 10%
Every time you apply for credit, a "hard inquiry" is recorded. Multiple applications in a short window can signal financial stress. Rate shopping for a mortgage or auto loan within a short period is typically treated as one inquiry by scoring models.
Common Things That Hurt Your Score
- Missing or late payments
- Maxing out credit cards
- Closing old accounts
- Applying for many new credit accounts at once
- Having an account go to collections
- Bankruptcy or foreclosure
How to Improve Your Credit Score
Credit improvement isn't instant, but these steps consistently make a difference over time:
- Pay every bill on time, every time. Set up autopay for at least the minimum due if you're forgetful.
- Pay down existing balances. Focus on high-utilization cards first.
- Don't close old accounts unless there's a compelling reason (e.g., high annual fee on a card you never use).
- Avoid applying for credit you don't need. Space out new applications.
- Check your credit report for errors. You're entitled to a free report from each of the three major bureaus annually at AnnualCreditReport.com. Dispute any inaccuracies.
- Become an authorized user. If a family member has a long-standing card in good standing, being added as an authorized user can boost your score.
How to Check Your Credit Score
Many banks and credit card providers now offer free credit score access through their apps or websites. You can also check for free via services like Credit Karma or Experian's free tier. These use soft inquiries that don't affect your score.
The Bottom Line
Your credit score is a financial tool — not a judgment of your worth. Understanding how it works puts you in the driver's seat. Focus on paying on time, keeping balances low, and letting your credit history grow. Steady, responsible habits consistently lead to higher scores over time.
