🔍 What Is a Credit Score?

Your credit score is a three-digit number that shows how "trustworthy" you are with credit.
It tells lenders how likely you are to repay loans or credit cards on time.

In the U.S., credit scores usually range from 300 to 850.

Score Range	Rating
800 – 850	Excellent
740 – 799	Very Good
670 – 739	Good
580 – 669	Fair
Below 580	Poor

🧠 How Is Your Credit Score Calculated?

Your score is mostly based on FICO or VantageScore models. Here’s a general breakdown:

🧾 1. Payment History – 35%

Do you pay bills on time? Late payments hurt your score the most.

💳 2. Credit Utilization – 30%

How much of your available credit are you using?
Tip: Try to stay under 30% usage per card.

🕒 3. Length of Credit History – 15%

The longer you've had credit, the better.

📚 4. Credit Mix – 10%

Having different types of credit (e.g., credit card, auto loan, student loan) helps.

📈 5. New Credit Inquiries – 10%

Too many recent applications for new credit can lower your score.
