Your Credit Score: How It Works and Why You Can Stop Stressing

Your credit score is a three-digit number that tells lenders how likely you are to pay back what you borrow. It's built from your history of paying bills and using credit, so it rises when your habits are steady. You're more than your credit score, and it will be healthy if your habits are healthy.

1. What a credit score and a credit report are

Your credit report is a record of how you've handled borrowed money. It lists your credit cards and loans, your balances, whether you paid on time and who has checked your credit. Three big companies keep these reports: Equifax, Experian and TransUnion. They're called credit bureaus.

Your credit score is a number a computer model calculates from one of those reports. Lenders, landlords and some insurers use it to make fast decisions about you.

The report is the full story, and the score is a one-line summary. Your report doesn't include your income, your savings or how hard you work. So a score is a narrow snapshot, not a grade on you as a person.

2. FICO vs. VantageScore, and what the numbers mean

There are two main scoring companies:

FICO makes the score most lenders use. Base FICO scores run from 300 to 850.
VantageScore was created by the three credit bureaus. Its newer versions, VantageScore 3.0 and 4.0, also use a 300 to 850 range.

You don't have just one score. Each company has several versions, and each bureau's report may differ a little. So your scores can vary by several points depending on where you look. That's normal.

Here's how myFICO describes FICO score ranges:

FICO score	What it means
800 and up	Exceptional
740–799	Very good
670–739	Good
580–669	Fair
Below 580	Poor, with fewer and pricier options

You don't need a perfect 850. As a rule of thumb, many lenders save their best rates for scores in the mid-700s and up.

3. The five things that make up a FICO score

myFICO says FICO scores are built from five factors, with these rough weights:

Factor	Weight	What it looks at
Payment history	35%	Do you pay on time?
Amounts owed	30%	How much of your available credit are you using?
Length of credit history	15%	How long have your accounts been open?
New credit	10%	Have you opened or applied for a lot of accounts lately?
Credit mix	10%	Do you have different kinds of credit, like cards and loans?

Two factors make up almost two-thirds of your score: paying on time and keeping balances low.

A big part of "amounts owed" is your credit utilization. That's how much of your credit card limits you're using right now. Say you have a $500 balance on a card with a $5,000 limit. Your utilization is 10%. Keeping it under 30% is a common rule of thumb, and lower is better.

4. Why your score can dip when you do something good

Sometimes a smart money move makes your score drop a little. This surprises a lot of people. It's okay, and it's usually short-lived.

Closing a credit card

Dana has two cards with $10,000 in total limits and a $2,000 balance. Her utilization is 20%. She closes a card with a $4,000 limit that she never uses. Now her limits total $6,000, and the same $2,000 balance puts her at about 33%. Her score may dip a bit.

Should Dana have kept the card? Maybe, if it had no annual fee. But if the card tempted her to spend, closing it was a fine choice. Once she pays her balance down, the dip goes away.

Paying off a loan

When you pay off a car loan or student loan, the account closes. If it was your only loan, your credit mix gets thinner. Your score may drop a few points. That doesn't mean paying it off was a mistake. You're debt-free, and that matters far more than a few points.

5. Hard vs. soft inquiries, and shopping for rates

A credit inquiry is a record that someone checked your credit. There are two kinds:

A soft inquiry happens when you check your own credit or a company pre-screens you for an offer. It doesn't affect your score.
A hard inquiry happens when you apply for credit, like a card, car loan or mortgage. It can lower your score.

For most people, one hard inquiry takes fewer than five points off a FICO score, according to myFICO. It stays on your report for up to two years, but FICO scores count it for only one year.

Shopping for the best rate

You can compare lenders without hurting your score much. FICO treats several mortgage, car loan or student loan inquiries in a short window as just one. Newer FICO versions use a 45-day window. Older ones use 14 days. FICO also skips these loan inquiries if they're less than 30 days old when your score is pulled.

So do your loan shopping within about two weeks to be safe. This doesn't work for credit cards. Each card application counts on its own.

6. How long negative items stay on your report

Mistakes don't last forever. Under the Fair Credit Reporting Act (FCRA), the federal law that governs credit reports:

Most negative items, like late payments and collections, can stay for seven years.
Bankruptcies can stay for up to ten years.

The effect also fades with time. A late payment from five years ago hurts much less than one from last month. Each month of on-time payments helps rebuild your score.

7. Check your reports for free

You can get your credit reports from all three bureaus for free every week at AnnualCreditReport.com. It's the official site set up under federal law. Watch out for look-alike sites that ask for a credit card.

Checking your own report is a soft inquiry, so it never hurts your score. A good habit is to look at all three a few times a year.

Your report is free, but your score may not be. Many credit card companies and banks now show you a free score in their app.

8. How to dispute an error

If you find something wrong, like an account that isn't yours or a late payment you made on time, you can dispute it:

Contact the credit bureau that shows the error. You can do it online, by mail or by phone. Explain what's wrong and why.
Send proof. Include copies, not originals, of statements or letters that back you up.
Contact the company that reported it too. That's the lender or collector, called a furnisher.
Keep copies of everything.

The bureau usually has 30 days to investigate. If the item is wrong, it must be fixed or removed. If you hit a wall, file a complaint with the CFPB (Consumer Financial Protection Bureau), the federal agency that protects consumers in financial matters.

9. Freezing your credit

A credit freeze stops new lenders from seeing your credit report. That makes it very hard for a thief to open an account in your name.

A freeze is free to place and free to lift. It doesn't affect your score, and it lasts until you lift it. You need to freeze your credit at each of the three bureaus. When you want to apply for a loan or card, lift it for a short time first.

A fraud alert is a lighter option. It asks lenders to verify your identity before opening an account. An initial alert lasts one year. An extended alert, for identity theft victims, lasts seven years.

10. Healthy credit habits

These five habits take care of most of your score:

Pay every bill on time. Set up autopay for at least the minimum payment.
Keep card balances low. Paying in full each month is best.
Keep old no-fee cards open. They help your utilization and the length of your history.
Apply for new credit only when you need it.
Check your reports a few times a year.

You don't need tricks or paid repair services. Time and steady habits do the work.

11. When your score really matters

Most days, your credit score doesn't matter at all. It matters when you want to borrow or rent:

Mortgage. This is where your score matters most. Say a lower score adds half a point to your rate on a $300,000, 30-year loan. At 6.5%, the payment for principal and interest is about $1,896 a month. At 7.0%, it's about $1,996. That's about $100 more a month, or roughly $35,900 over 30 years. Try your own numbers with our mortgage payment calculator.
Car loan. A higher score usually gets you a lower rate.
Renting. Many landlords check credit before they approve you.
Insurance. In most states, car and home insurers can use a credit-based insurance score to help set your price. It's a separate score that estimates how likely you are to file a claim.

If one of these is coming up soon, check your reports and keep balances extra low.

12. If you live in New York

New York has a strong protection for medical debt. Under a state law signed on December 13, 2023, hospitals, licensed health care providers and ambulance companies can't report unpaid medical bills to the credit bureaus. The bureaus can't include that debt in a New Yorker's credit report either.

If you see a medical bill on your report, you can dispute it. A balance on a regular credit card isn't medical debt under this law, even if you used it to pay a doctor. The exception is a card made only for paying health care bills.

Common mistakes with your credit score

Missing a payment. Payment history is the biggest factor. Autopay prevents this.
Maxing out a card. High utilization can drop your score fast.
Panicking over small dips. A few points after closing a card or paying off a loan is normal.
Paying for "credit repair." You can dispute errors yourself for free.
Opening many cards at once. Hard inquiries and new accounts add up.
Never checking your reports. Errors and fraud can go unnoticed for years.

Frequently asked questions

Does checking my own score lower it?

No. Checking your own credit is a soft inquiry and never affects your score.

Do I need to carry a balance to build credit?

No. This is a common myth. Paying your full balance every month builds credit just as well, and you pay no interest.

How long does it take to build a credit score?

You usually need at least one account that's been open for about six months before a FICO score can be calculated. After that, a year or two of on-time payments goes a long way.

Does my income affect my score?

No. Your income isn't on your credit report. Lenders ask about it separately when you apply.

The bottom line

Your credit score is a summary of your borrowing habits, not a measure of your worth. Pay on time, keep balances low and check your reports for free. Small dips come and go, and steady habits always win.
