What Is a Credit Score?

A credit score is a three-digit number that rates your creditworthiness. FICO scores range from 300 to 850. The higher the score, the more likely you are to get approved for loans and for better rates.

A credit score is based on your credit history, which includes information like the number accounts, total levels of debt, repayment history, and other factors. Lenders use credit scores to evaluate your credit worthiness, or the likelihood that you will repay loans in a timely manner.

There are three major credit bureaus in the U.S.: Equifax, Experian, and TransUnion. This trio dominates the market for collecting, analyzing, and disbursing information about consumers in the credit markets.

How Credit Scores Work

A credit score can significantly affect your financial life. It plays a key role in a lender’s decision to offer you credit. Lenders are more likely to approve you for loans when you have a higher credit score, and are more likely to decline your loan applications when you have lower scores. You can also get better interest rates when you have a higher credit score, which can save you money in the long-term.

Conversely, a credit score of 700 or higher is generally viewed positively by lenders, and may result in a lower interest rate.Scores greater than 800 are considered excellent. Every creditor defines its own ranges for credit scores and its own criteria for lending. Here are the general ranges for how credit scores are categorized.

  • Excellent: 800–850
  • Very Good: 740–799
  • Good: 670–739
  • Fair: 580–669
  • Poor: 300–579


Your credit score also may determine the size of deposit required to get a smartphone, cable service, or utilities, or to rent an apartment.

How Your Credit Score Is Calculated

The three major credit reporting agencies in the U.S. (Equifax, Experian, and TransUnion) report, update, and store consumers’ credit histories. While there can be differences in the information collected by the three credit bureaus, five main factors are evaluated when calculating a credit score:

  1. Payment history (35%)
  2. Amounts owed (30%)
  3. Length of credit history (15%)
  4. Types of credit (10%)
  5. New credit(10%)
  • Payment history: Your payment history includes whether you've paid your bills on time. It takes into account how many late payments you've had, and how late they were.
  • Amounts owed: Amounts owed is the percentage of credit you've used compared to the credit available to you, which is known as credit utilization.
  • Length of credit history: Longer credit histories are considered less risky, as there is more data to determine payment history.
  • Credit mix: A variety of credit types shows lenders you can manage various types of credit. It can include installment credit, such as car loans or mortgage loans, and revolving credit, such as credit cards.
  • New credit: Lenders view new credit as a potential sign you may be desperate for credit. Too many recent applications for credit can negatively affect your credit score.

If you have many credit cards and want to close some that you do not use, closing credit cards can indeed lower your score.

Instead of closing accounts, gather up the cards you don’t use. Keep them in a safe place in separate, labeled envelopes. Go online to access and check each of your cards. For each, ensure that there is no balance and that your address, email address, and other contact info are correct. Also, make sure that you don’t have autopay set up on any of them. In the section where you can have alerts, make sure you have your email address or phone in there. Make it a point to regularly check that no fraudulent activity occurs on them, since you aren’t going to be using them. Set yourself a reminder to check them all every six months or every year to make sure there have been no charges on them and that nothing unusual has happened.


VantageScore is a consumer credit rating product developed by the Equifax, Experian, and TransUnion credit bureaus as an alternative to the FICO Score.

FICO creates a single bureau-specific score for each of the three credit bureaus, using only information from that bureau. As a result, the FICO is actually three scores, not one, and they can vary slightly as each bureau will have different calculation methods. A VantageScore is a single, tri-bureau score, combining information from all three credit bureaus and used by each of them the same.


FICO score is the most popular credit score, used by about 90% of lenders.

How to Improve Your Credit Score

When information is updated on a borrower’s credit report, their credit score changes and can rise or fall based on new information. Here are some ways that your can improve your credit score:

  • Pay your bills on time: Six months of on-time payments are required to see a noticeable difference in your score.
  • Increase your credit line: If you have credit card accounts, call and inquire about a credit increase. If your account is in good standing, you should be granted an increase in your credit limit. However, it is important not to spend this amount so that you maintain a lower credit utilization rate. Meanwhile, try to pay down your debt.
  • Don’t close a credit card account: If you are not using a certain credit card, it is best to stop using it instead of closing the account. Depending on the age and credit limit of a card, it can hurt your credit score if you close the account.
  • Work with one a credit repair companies: If you don’t have the time to improve your credit score, credit repair companies can negotiate with your creditors and the threecredit agencies on your behalf, in exchange for a monthly fee.
  • Correct any errors on your credit report: You are entitled to one free credit report per year from each of the main credit bureaus. You can get your report through AnnualCreditReport.com. You can also hire a monitoring serviceto help keep your information secure.
