Credit Score: Definition & Example

What Is a Credit Score?
A credit score is a three-digit number, usually from 300 to 850, that estimates how likely a person is to repay debt based on the information in their credit report.
What does credit score mean?
The most widely used scores are FICO and VantageScore. Both are calculated from credit bureau data. FICO weighs payment history (about 35%), amounts owed (30%), length of history (15%), new credit (10%), and credit mix (10%).
Each of the three major bureaus, Equifax, Experian, and TransUnion, may hold slightly different data, so a person can have different scores at each. Lenders may also use industry-specific versions, such as auto or mortgage scores.
Credit scores do not include income, bank balances, or rent payments unless those are reported to a bureau. That is why landlords often review income separately and why some renters have thin credit files despite a long history of paying rent.
Credit score example
An applicant has a FICO score of 712. Her report shows eight years of history, no late payments in five years, and credit card balances using 18% of her limits. A single 30-day late payment from six years ago still appears but has little effect on the score.
