Credit Score Basics
Module: Credit and Debt • Lesson 6
Your credit score is your financial reputation
Credit scores are used by lenders, landlords, employers, and more to measure how trustworthy you are with money.
A good credit score opens doors. A bad one closes them.
What is a credit score
A credit score is a three-digit number that represents how responsibly you manage credit and debt.
Credit scores typically range from 300 to 850.
Higher scores mean:
- • Lower risk to lenders
- • Better loan terms
- • Lower interest rates
- • More financial opportunities
Lower scores mean:
- • Higher risk to lenders
- • Harder to get approved
- • Higher interest rates
- • Limited financial options
Your credit score is calculated based on your credit behavior over time.
Credit score ranges
800-850: Exceptional
Best rates, highest approval odds
740-799: Very Good
Excellent terms, strong approval
670-739: Good
Decent rates, reliable approval
580-669: Fair
Higher rates, limited options
300-579: Poor
Very high rates, difficult approvals
Most credit scoring models use FICO or VantageScore. Both use similar ranges, though exact calculations vary.
Why credit scores matter
Loans and Credit Cards
Lenders check your credit score to decide whether to approve you and at what interest rate. Better scores unlock better terms.
Renting an Apartment
Landlords review credit scores to assess whether you will pay rent on time. Low scores can result in denials or higher security deposits.
Employment
Some employers check credit reports (not scores directly) to evaluate financial responsibility, especially for positions handling money.
Insurance Rates
Auto and home insurance companies may use credit-based insurance scores to set premiums. Better credit can mean lower rates.
Utilities and Phone Plans
Service providers check credit to determine if deposits are required. Good credit eliminates these upfront costs.
Credit scores affect nearly every major financial decision in your life.
How credit scores are built
Credit scores are calculated using data from your credit reports, which track your borrowing and repayment history.
Three major credit bureaus collect this data:
Experian
Equifax
TransUnion
What your credit report includes:
Personal information (name, address, SSN)
Credit accounts (cards, loans, payment history)
Public records (bankruptcies, liens)
Credit inquiries (hard and soft pulls)
Your credit report is like a financial transcript.

Starting your credit journey
If you have never had credit before, you have no credit score yet.
You need to establish credit history first.
Ways to start building credit:
• Open a secured credit card
• Become an authorized user on someone else's card
• Apply for a student credit card or credit builder loan
• Use services that report rent or utility payments to credit bureaus
The earlier you start building credit responsibly, the better.
