Credit scores are three-digit numbers lenders use to help inform them whether you may qualify for a loan. Lenders also use credit scores to help them determine the interest rate they might offer you. If you want to buy a home or refinance a home you own, lenders are likely to look at your credit score before they offer you a mortgage.

Many people have a credit score between 550 and 750, with a higher score being better than a lower one. Because your credit score can affect your ability to buy or refinance a home, and the amount of money you will pay in interest over the life of the loan, it’s a good idea to know your credit score and make sure it is as high as possible when applying for a loan.

You credit score is calculated from the information in your credit report. Credit reports contain details about your financial history including

Payment history

The history of the payments you’ve made on loans is an important factor in your credit score. Lenders like to see you consistently pay your bills on time before they offer you a loan. If you see errors in your payment history in your credit report, you’ll want to work with the credit bureaus to get them corrected.

Amounts owed

How much you currently owe and the number of loans and credit accounts you have affect you credit score. For example, if you have reached the maximum balance on several credit cards, this can influence your credit score. The Consumer Financial Protection Bureau (CFPB) recommends you try to limit the credit you use to 30 percent of your credit limit.

Length of credit history

How long you have accounts and loans impact your credit score. When you have reliably made your loan payments over a long period of time, this can raise your credit score.

Credit mix

Lenders look at the types of credit you have such as mortgage, car loans, student loans, credit card debt, and more. Having a mix of credit card accounts and installment loans you have managed responsibility might help improve your credit score according to the Fair Isaac Corporation (FICO).

New credit

How often you apply for new credit also impacts your score. The CFPB notes that people who have applied for several new credit accounts in a short period may be seen as having problems with their finances.

There is no single answer to the question “What is a good credit score?” Different lenders have different standards for credit scores they will accept on the loans they offer. And the three credit reporting agencies do not rank credit scores in exactly the same way.

Experian and Equifax both rank credit scores in the ranges you see below. They believe any score above 670 is good and any score below 580 is poor.
