A credit score is a three-digit number that lenders use to predict whether you will pay back borrowed money on time
Your credit score does not measure how much money you have, how responsible you are as a person, or whether you deserve a loan. It measures one specific thing: your history of borrowing and repaying. The score sits between 300 and 850 on most scales. A higher number means lenders see you as less risky to lend to, which usually means lower interest rates when you borrow.
Three companies — Equifax, Experian, and TransUnion — collect the data that goes into your score. They are called credit bureaus. Banks, credit card companies, landlords, and other lenders report to these bureaus when you open an account, make a payment, or miss one. The bureaus then sell that information to lenders, employers, and insurance companies. Your score changes as your borrowing behavior changes.
Key Takeaways
- Your credit score measures your history of borrowing and repaying, not your income or net worth.
- Payment history — whether you pay on time — makes up 35 percent of most credit scores, so a single late payment can lower your score significantly.
- The amount you owe compared to your credit limits (called credit utilization) makes up 30 percent, so carrying high balances hurts your score even if you pay on time.
- The length of your credit history, the mix of types of credit you use, and new credit inquiries make up the remaining 35 percent.
- You have the right to see your credit report for free once per year from each bureau at annualcreditreport.com.
The five factors that make up your score
Payment history (35 percent of your score) is whether you pay your bills by the due date. A payment 30 days late, 60 days late, or sent to a collection agency all damage your score. Payments from the past seven years matter most, but late payments stay on your report for up to seven years. One missed payment can drop your score by 100 points or more, depending on how high it was to start.
Credit utilization (30 percent) is the total amount you owe divided by your total credit limits across all accounts. If you have three credit cards with $1,000 limits each and you owe $900 total, your utilization is 30 percent. Lenders prefer to see utilization below 30 percent. Maxing out cards or carrying balances close to the limit signals that you are stretched thin financially, even if you pay on time.
Length of credit history (15 percent) is how long your oldest account has been open. A longer history shows you have managed credit over time. Closing old accounts can shorten this number and hurt your score. Opening many new accounts in a short period can also lower your average account age.
Credit mix (10 percent) is the variety of credit types you use. Credit cards, car loans, mortgages, and personal loans all count as different types. Having only credit cards looks riskier than having credit cards plus an installment loan you are paying down. You do not need to seek out new types of credit to improve this factor — it matters only if you already have multiple types.
New credit inquiries (10 percent) are requests from lenders to see your credit report when you explore for a loan or card. A hard inquiry (when you actually explore) lowers your score slightly and stays on your report for two years. Checking your own score or a lender pre-may have access to you does not count as a hard inquiry. Multiple hard inquiries in a short time can signal that you are desperate for credit.
Why lenders care about your credit score
Lenders use your credit score to decide three things: whether to lend to you at all, how much interest to charge you, and what credit limit to offer. A score of 670 or higher is generally considered good. A score below 580 makes borrowing difficult and expensive. The difference between a 650 score and a 750 score can mean paying thousands of dollars more in interest over the life of a mortgage or car loan.
Your score also affects things beyond borrowing. Landlords often check credit scores before renting to you. Insurance companies use credit information to set premiums. Some employers check credit reports (though not the score itself) before hiring. Utility companies may require a deposit based on your credit history.
How your score changes over time
Your credit score is not fixed. It updates as new information reaches the credit bureaus, usually within 30 to 45 days of an event. Paying a bill on time raises your score. Missing a payment lowers it. Paying down a credit card balance raises it. Opening a new card lowers it slightly at first because of the hard inquiry and the new account.
The impact of any single action depends on your current score and history. A late payment hurts someone with a 750 score more than someone with a 600 score. Paying down debt helps someone with high utilization more than someone already below 30 percent. Building credit takes time — typically six months to a year of on-time payments to see meaningful improvement after a negative event.
The difference between your score and your credit report
Your credit report is a detailed record of every account you have opened, every payment you have made or missed, and every time a lender has checked your credit. Your credit score is a number calculated from that report. You can have errors on your report that drag down your score — a payment marked late when you paid on time, an account opened in your name that you did not open, or a debt that was paid off but still showing as active.
You have the right to see your full credit report for free once per year from each of the three bureaus at annualcreditreport.com. You can also dispute errors directly with the bureau. If a bureau cannot verify an error within 30 days, it must remove it from your report. Removing errors can raise your score.
What your credit score does not measure
Your credit score ignores your income, savings, investments, and job stability. A person earning $30,000 a year with perfect credit can have a higher score than a person earning $300,000 with late payments. Your score does not reflect whether you are a good person, a reliable employee, or a safe driver. It reflects only whether you have borrowed money and paid it back on schedule.
Your score also does not include utility bills, rent payments, or medical debt unless they have been sent to a collection agency. Paying rent on time does not build credit. Missing rent payments does not hurt your credit score directly, though an eviction can appear on your report and damage your score indirectly.
Frequently Asked Questions
Does checking my own credit score lower it?
No. Checking your own score is a soft inquiry and does not affect your credit. Only hard inquiries — when you explore for credit — lower your score. You can check your score as often as you want without penalty.
How long does a late payment stay on my credit report?
A late payment stays on your report for seven years from the date it was first reported as late. Its impact on your score decreases over time, especially after two or three years of on-time payments. After seven years, it must be removed.
Can I improve my credit score quickly?
Meaningful improvement takes months, not weeks. Paying down credit card balances can raise your score within 30 to 45 days. Building a longer payment history takes longer. A single late payment can drop your score by 100 points, but recovering from it usually takes six months to a year of on-time payments.
What is a good credit score?
Scores of 670 to 739 are generally considered good. Scores of 740 and above are very good or excellent. Scores below 580 make borrowing difficult. Most lenders have their own thresholds, so a score that qualifies you for one loan may not may have access to you for another.
Do I have one credit score or three?
You have three scores — one from each bureau — because each bureau may have slightly different information about you. Lenders may check one, two, or all three. You also have multiple scores within each bureau because different scoring models exist. The most common is the FICO score, but VantageScore and others are also used.
