What is Credit?
Credit is essentially borrowed money that you can use to purchase goods and services with the promise to repay later. It comes with conditions, such as interest rates, repayment terms, and borrowing limits.
There are several forms of credit, including:
- Revolving Credit – This type allows you to borrow up to a certain limit, repay, and borrow again. Examples: credit cards, lines of credit.
- Installment Credit – This involves borrowing a fixed amount and repaying it in equal monthly installments. Examples: personal loans, mortgages, car loans.
- Open Credit – Typically used for utilities or services where the balance must be paid in full each month.
What is a Credit Score?
A credit score is a three-digit number, usually ranging from 300 to 850, that represents your creditworthiness. Lenders use this score to determine the likelihood of you repaying debt.
The higher your credit score, the more financially trustworthy you appear. A low score can mean higher interest rates, stricter loan terms, or even outright rejection of your application.
Popular Credit Scoring Models
- FICO Score – The most widely used credit scoring system.
- VantageScore – Another scoring model, often used by free credit monitoring services.
Why Are Credit Scores Important?
Your credit score can impact nearly every financial decision in your life. Some of the key areas include:
- Loan Approvals – Banks check your score before approving personal, car, or home loans.
- Interest Rates – Higher scores usually mean lower interest rates.
- Credit Card Approvals – Premium cards often require excellent credit.
- Housing Applications – Landlords use credit scores to assess tenants.
- Employment – Some employers check credit reports (not scores) during hiring.
- Insurance Premiums – In some regions, a higher score can lower car insurance costs.
Factors That Affect Credit Scores
Credit scores aren’t random—they’re based on specific factors. Here’s what goes into your score:
- Payment History (35%) – Do you pay bills on time? Late or missed payments hurt the most.
- Credit Utilization (30%) – The ratio of used credit to available credit. Keep it below 30%.
- Length of Credit History (15%) – Older accounts strengthen your score.
- Credit Mix (10%) – A healthy mix of credit types (credit cards, loans, mortgages).
- New Credit Inquiries (10%) – Too many applications in a short time can lower your score.
What is a Good Credit Score?
Credit score ranges vary, but here’s a general breakdown (FICO):
- 300–579: Poor
- 580–669: Fair
- 670–739: Good
- 740–799: Very Good
- 800–850: Excellent
How to Build Credit From Scratch
If you’re new to credit, here’s how to establish and build your score:

Common Credit Myths

How Credit Cards Impact Your Credit Score
Credit cards are one of the biggest influencers of your score. Responsible usage can build credit, but misuse can destroy it.
Good Habits:
- Pay in full each month.
- Keep utilization below 30%.
- Avoid unnecessary new accounts.
Bad Habits:
- Missing payments.
- Maxing out cards.
- Frequently applying for new cards.
Credit Reports vs. Credit Scores
- Credit Report – A detailed record of your borrowing history. Includes accounts, balances, and payment history.
- Credit Score – A number derived from your credit report that summarizes your creditworthiness.
The Role of Credit Bureaus
Credit bureaus collect and maintain your financial data. The main three in the U.S. are:
- Experian
- Equifax
- TransUnion
These agencies compile your credit reports, which are then used to calculate your scores.
The Impact of Debt on Credit
Not all debt is bad. Some debt, like a mortgage or student loan, can help build credit if managed responsibly. However, excessive high-interest debt (like credit cards) can damage your score and financial health.
Credit & Major Life Decisions
- Buying a House – Mortgage lenders heavily rely on credit scores.
- Buying a Car – Better scores mean lower car loan interest rates.
- Starting a Business – Lenders may check your personal credit before approving business loans.
How Long Does Negative Information Stay on Your Report?
- Late payments: 7 years
- Collections: 7 years
- Bankruptcies: 7–10 years
- Hard inquiries: 2 years
International Credit Scores
Credit systems vary by country. For example:
- U.S. uses FICO and VantageScore.
- UK uses Experian, Equifax, and TransUnion but with different ranges.
- India uses CIBIL score (300–900).
Tips to Maintain Excellent Credit Long-Term
- Pay every bill on time.
- Use less than 30% of available credit.
- Review credit reports annually.
- Don’t close old accounts unnecessarily.
