Credit Score
A numerical rating (300–850) representing an individual's creditworthiness based on their credit history and behavior.
A credit score is a numerical representation of an individual's creditworthiness — their likelihood of repaying debt obligations on time — derived from an analysis of their credit history. Scores range from 300 (poor) to 850 (exceptional) and are used by lenders, landlords, insurers, and employers to assess financial reliability.
The two dominant credit scoring models are FICO (Fair Isaac Corporation) and VantageScore. FICO scores are the most widely used by mortgage, auto, and credit card lenders. FICO 8 — the most common version — weighs five factors: Payment History (35%), Amounts Owed / Credit Utilization (30%), Length of Credit History (15%), Credit Mix (10%), and New Credit / Inquiries (10%).
Score ranges: 300–579 Poor; 580–669 Fair; 670–739 Good; 740–799 Very Good; 800–850 Exceptional. Borrowers with scores above 760 typically qualify for the best available interest rates on mortgages and auto loans; those below 620 will struggle to qualify for conventional mortgages at all.
Credit scores are calculated from data in credit reports maintained by the three major bureaus — Equifax, Experian, and TransUnion — each of which may have slightly different information and therefore produce slightly different scores. Consumers are entitled to one free credit report per bureau per year via AnnualCreditReport.com.
Credit score impacts extend beyond borrowing: landlords check scores for rental applications; auto insurers use insurance scores (related to credit scores) in 46 states; employers in financial services may check credit history. A 100-point difference in credit score can mean thousands of dollars in additional interest over the life of a mortgage.
Building credit requires using credit responsibly — on-time payments, low utilization, avoiding excessive new credit applications, and maintaining long-standing accounts.
FAQs
How long does it take to build a good credit score?
Starting from no credit, achieving a 'Good' score (670+) typically takes 6–12 months with consistent on-time payments on at least one credit account. Reaching 'Very Good' (740+) usually takes 2–3 years of excellent credit behavior. Recovering from serious negative events (bankruptcy, collections) takes 7–10 years for those items to fall off the credit report.
Does checking my own credit score hurt it?
No. Checking your own credit score or report is a 'soft inquiry' and does not affect your score. Only 'hard inquiries' — initiated by lenders when you apply for credit — affect your score, typically reducing it by 2–5 points temporarily. Multiple hard inquiries within 14–45 days for the same loan type (rate shopping) are typically treated as a single inquiry.
What is the fastest way to improve a credit score?
The fastest improvements come from paying down revolving credit card balances (reducing utilization below 30% has immediate impact when the lender reports), paying off any collections, disputing errors on your credit report, and becoming an authorized user on a family member's longstanding, low-utilization account. Strategies affecting payment history improve scores more slowly over time.
