What Is Credit?
Credit is your ability to borrow money or access goods and services with the promise to pay later. When you use credit responsibly and make payments on time, you build a positive credit history that demonstrates your reliability to future lenders.
Key credit concepts:
- Credit score: A numerical representation (300-850) of your creditworthiness
- Credit report: Detailed history of your credit accounts and payment behavior
- Credit utilization: How much credit you're using compared to your available limits
- Credit history: The length of time you've been using credit
- Credit mix: The variety of credit types you have (cards, loans, mortgages)
- Credit inquiries: Records of when lenders check your credit
Credit Score Ranges Explained
Credit scores range from 300 to 850, with higher scores indicating better creditworthiness and access to better loan terms.
What each range means:
- Excellent (800-850): Access to the best rates and terms available
- Very Good (740-799): Strong credit, competitive rates on most products
- Good (670-739): Above-average credit, decent rates and approval odds
- Fair (580-669): Below-average credit, higher rates and fees
- Poor (300-579): Difficulty getting approved, very high rates if approved

Questions about credit
- How long does it take to build good credit?
- You can establish a basic credit score within 3-6 months of opening your first account. Building good credit (670+) typically takes 12-24 months of consistent positive behavior, while excellent credit (740+) usually requires 2-3 years.
- What's the difference between credit score and credit report?
- Your credit report is a detailed history of your credit accounts and payments. Your credit score is a number (300-850) calculated from information in your credit report that represents your creditworthiness.
- How often does my credit score change?
- Credit scores can change whenever new information is reported to credit bureaus, which typically happens monthly. Significant changes usually occur when you pay down balances, miss payments, or open/close accounts.
- Can I have good credit with no credit history?
- No, you need some credit history to generate a credit score. However, you can start building credit quickly with a secured credit card, becoming an authorized user, or getting a credit-builder loan.
- Why do I have different credit scores?
- You have multiple credit scores because there are different scoring models (FICO®, VantageScore®) and three credit bureaus that may have slightly different information about you.
- How long do negative items stay on my credit report?
- Most negative items stay for 7 years, including late payments, collections, and charge-offs. Bankruptcies stay for 7-10 years. Hard inquiries remain for 2 years but only affect your score for about 1 year.
- Can I fix my credit quickly?
- Some improvements can happen quickly (paying down balances, disputing errors), but building strong credit generally takes time. Be wary of companies promising instant credit repair—legitimate credit building requires patience and good habits.
