What Is a Credit Score

Last updated: March 31, 2026

Quick Answer: A credit score is a three-digit number, typically ranging from 300 to 850, that represents your creditworthiness — how likely you are to repay borrowed money on time. Lenders use it to decide whether to approve you for loans, credit cards, and mortgages, and what interest rate to offer.

Key Facts

Overview

Your credit score is essentially a financial report card. It summarizes your entire credit history into a single number that lenders can quickly evaluate. A higher score means lower risk to the lender, which translates to better loan terms and lower interest rates for you. A lower score can mean higher interest rates, lower credit limits, or outright denial.

How Credit Scores Are Calculated

The FICO model, the most widely used scoring system, weighs five factors:

Score Ranges

How to Improve Your Score

Pay all bills on time (set up autopay), keep credit card balances low, don't close old accounts, limit new credit applications, and check your credit report regularly for errors at annualcreditreport.com (free weekly access).

Related Questions

Does checking my credit score lower it?

No. Checking your own credit score is a "soft inquiry" and has no effect on your score. Only "hard inquiries" — when a lender checks your credit for a loan or credit card application — can temporarily lower your score by a few points.

How long does it take to build credit?

You can establish a credit score within 3–6 months of opening your first credit account. Building a good score (700+) typically takes 1–2 years of responsible credit use. Negative marks like late payments stay on your report for 7 years, while bankruptcies remain for 10 years.

What is the highest credit score possible?

The highest FICO score is 850, and the highest VantageScore is also 850. However, there is virtually no practical difference between a 780 and an 850 — both qualify for the best rates and terms. Only about 1.6% of Americans have a perfect 850 score.
