Credit score definition
Your credit score, a number between 300 and 850, is calculated using information from your credit reports. Lenders use it to judge how likely you are to repay money you borrow, which affects the financial products available to you. Higher credit scores can open the door to more financial products that often have better rates and terms. Lower scores, on the other hand, can make it harder to qualify for things like credit cards and loans. Fewer choices often leads to higher borrowing costs, like higher interest rates. Your credit score affects a lot more than just loans and credit cards. For example, insurers may use credit scores to set auto or homeowners policies. Landlords may check your credit score when deciding who to rent to. Even utility providers look at your score to determine who gets the best cell phone plans and who has to make bigger deposits to get utilities like electricity and water.

How is your credit score calculated?
Credit scores are based on the information in your credit reports from the three major credit bureaus: Experian, Equifax and TransUnion. Since each major credit bureau maintains its own credit report, you have more than one score — and those numbers fluctuate all the time. Your scores are then categorized within ranges, outlined by the two major credit scoring companies FICO and VantageScore. These credit score ranges generally determine whether your score is seen as excellent, good, fair or poor by lenders. FICO and VantageScore have their own distinct ranges, which means a “good” credit score at VantageScore might not quite make the cut at FICO. Score calculations consider the following factors: Payment history is your record of paying your bills on time every month. Payment history Credit utilization is the amount of available credit you're using at a given moment. Ideally, you only want to be using 30% or less at one time. Credit utilization Length of credit history is how long you’ve had credit. A longer history gives lenders a better look at how you’ve borrowed and paid money back over time. Length of credit history Length of credit history Credit mix is the types of credit in your portfolio. While not a huge factor, having a variety of credit types shows lenders how you manage revolving credit (credit cards) and installment loans (car, student and personal loans). Credit mix FICO and VantageScore each use their own formulas to weigh these factors. The end result is your credit score. Your score can vary depending on the scoring model and which credit bureau’s report was used. It’s also important to know that not all lenders report to all three credit bureaus, so some information might not be on every report » Learn more: Which factors affect your credit score? » Learn more:How to build your credit
