What Is a Credit Score?
A credit score is a three-digit number - typically between 300 and 850 - that summarizes your creditworthiness based on your credit history. Lenders use this number to quickly assess how likely you are to repay borrowed money on time.
The most widely used scoring model is FICO, developed by Fair Isaac Corporation. Over 90% of top lenders use FICO scores. VantageScore, developed jointly by the three major bureaus, is also widely used, particularly for educational and monitoring purposes.
Credit Score vs. Credit Report
The Five FICO Score Factors
FICO scores are calculated from five categories, each weighted differently:
1. Payment History (35%)
The single most important factor. Even one 30-day late payment can drop a good score by 60–110 points. Set up autopay to protect this factor. See what affects your credit score for more detail.
2. Amounts Owed / Utilization (30%)
Your credit utilization ratio - balances ÷ limits - is the most actionable factor. Keeping this under 10% can significantly boost your score. Read our full credit utilization strategy guide.
3. Length of Credit History (15%)
Longer history is better. This includes the age of your oldest account, newest account, and average age. Never close old credit cards unnecessarily - they're valuable for this factor.
4. Credit Mix (10%)
Having a mix of revolving credit (credit cards) and installment loans (auto, mortgage, student loans) demonstrates you can manage different credit types responsibly.
5. New Credit (10%)
Each time you apply for credit, a hard inquiry is recorded. Multiple inquiries in a short period can signal financial stress. Rate-shopping for mortgages/auto loans within 45 days counts as a single inquiry.
Credit Score Ranges
| Score Range | Category | What It Means | Best Rates Available? |
|---|---|---|---|
| 800–850 | Exceptional | Top-tier borrower - you qualify for the best rates on anything | Yes |
| 740–799 | Very Good | Access to most premium rates and products | Yes (most) |
| 670–739 | Good | Approved for most credit products at reasonable rates | Sometimes |
| 580–669 | Fair | Approved for basic products, higher interest rates | Rarely |
| 300–579 | Poor | Limited approval odds, secured cards only | No |

Frequently Asked Questions
What is a good credit score?
A FICO score of 670–739 is considered 'good.' Scores of 740–799 are 'very good' and 800+ is 'exceptional.' For the best mortgage rates, lenders typically want to see 740+.
How often do credit scores update?
Your credit score updates whenever your creditors report new information to the bureaus - typically once per month. So your score can change monthly based on new payments, balance changes, or new accounts.
Does checking my own credit score hurt it?
No. Checking your own score (a 'soft inquiry') has no impact on your credit score. Only 'hard inquiries' from lenders when you apply for new credit can temporarily lower your score by a few points.
Why do I have different scores?
You have multiple credit scores because there are multiple scoring models (FICO 8, FICO 9, VantageScore 3.0, etc.) and three credit bureaus (Equifax, Experian, TransUnion) each maintaining slightly different records.
