How Your Credit Score Is Calculated

Your credit score is just a number between 300 and 850. Think of it like a grade in school. 300 is an F. 850 is a perfect A+. Most people are somewhere in the middle.

Lenders look at this number to decide if they trust you with a credit card or loan. A higher score means better cards, lower interest rates, and more money in your pocket over time.

Your score is calculated from five things. Here is each one explained simply:

1. Do You Pay On Time? (35% of your score)

This is the biggest one. Every time you pay a bill on time, your score goes up a little. Every time you miss a payment, your score drops a lot. One late payment can drop your score by 50–100 points. It stays on your record for 7 years.

The fix is simple: set up autopay. Go into your bank app and set every credit card to pay at least the minimum payment automatically. You will never accidentally miss a payment again.

2. How Much of Your Credit Are You Using? (30% of your score)

If your credit card has a $1,000 limit and you owe $800, you are using 80% of your credit. That is too high and your score will suffer. If you only owe $100, you are using 10% — that is great.

The rule is: try to keep your balance below 30% of your limit. Below 10% is even better. If your limit is $1,000, try not to carry more than $100–$300 on it.

3. How Long Have You Had Credit? (15% of your score)

The longer you have had a credit card, the better. A 10-year-old account helps more than a brand new one. This is why you should never close old credit cards, even ones you do not use anymore.

If you close an old card, the average age of your accounts goes down and your score drops. Keep old cards open. Make one small purchase every few months to keep them active.

4. Do You Have Different Types of Credit? (10% of your score)

Having a credit card AND a car loan AND a student loan is better than having only credit cards. Mixing different types of credit shows lenders you can handle different kinds of borrowing.

Do not borrow money you do not need just to improve this. It only makes a small difference anyway.

5. Have You Applied for New Credit Recently? (10% of your score)

Every time you apply for a new card or loan, your score drops a tiny amount — about 5–10 points. This is called a hard inquiry. It goes away after about 2 years and stops affecting your score after about 6 months.

The lesson: do not apply for 5 credit cards in one month. Apply for one, wait 6 months, then apply for another if you want.

What Does NOT Affect Your Score

Your income does not affect your score. A millionaire with bad habits can have a low score. A teacher who always pays on time can have a perfect score. Your age, gender, race, and job do not count either.
