When you apply for a credit card, apartment rental, mortgage or car loan, two metrics help would-be lenders assess the likelihood that you’ll pay as agreed: your credit scores and credit reports.
Your credit reports hold detailed information about your past use of credit. That data then gets calculated into a simple number representing your creditworthiness — a credit score. Think of reports like a medical record, which lists facts such as symptoms and test results, and scores as the resulting diagnosis.
Let’s break it down:
A credit score is a number that lenders use to evaluate how safe or risky you are as a customer. The kind most commonly used to make credit decisions is the FICO score, which comes in multiple versions, many of them specialty scores for products such as auto loans or credit cards. FICO’s competitor, VantageScore, also is used in lending decisions. (You can get a free credit score from VantageScore weekly at NerdWallet’s site.)
All credit scores are derived from information in your credit reports. The most important factors are:
- You history of repayment, and whether you have derogatory marks for being late or defaulting.
- How much money you owe compared to your credit limits, called credit utilization ratio.
- How often you have applied for credit recently, called “hard inquiries.”
- How long you’ve had credit accounts.
- The types of credit you have (the kind with fixed payments, like an auto loan, or variable payments, like a credit card).
Your scores will fluctuate depending on your account activity. VantageScore and most versions of FICO range from 300 to 850. Scores of 690 or above are deemed “good” and 720 or above are considered “excellent.” The two scoring models look at the same factors, so if you have a good score on one, you’ll likely have a good score on the other.
When you apply for a credit card or a loan, the lender will check your credit score to determine your eligibility. It’s smart to monitor your score yourself so you’ll have an idea of how a lender might size you up. This can be especially useful if you are looking to build your credit. Just use the same version of the same score every time. It’s like weighing yourself; using the same scale each time screens out slight variations due to equipment.
Your credit reports give a comprehensive list of your lines of credit and payment history, but they don’t contain your credit score. Three major credit-reporting companies — Equifax, Experian and TransUnion — compile the reports.
Credit reports often run to many pages as they detail all the accounts you’ve ever opened or closed, the loans you’ve taken out, and how diligently you’ve paid off outstanding balances. If you’ve ever been sued over debt or filed for bankruptcy, that will appear on your credit report, too.
If you’ve never had credit accounts, you probably don’t have credit reports yet. It’s important to establish a credit history because lenders, landlords, insurers and employers use credit reports to evaluate borrowing history and determine applicants’ eligibility for loans, credit cards, rentals, insurance policies and jobs.
Reports sometimes have errors, so it’s important to examine them carefully and dispute any mistakes you find with the company that issued the report. Everyone is legally entitled to one free credit report each year direct from each of the three credit-reporting companies.

Good credit scores are key to accessing financial products. If you spend responsibly, pay off balances and are careful about opening new accounts, you’ll be well on your way to having healthy credit and the documentation to back it up.
