Credit scores and your first credit card
Educational content only. Money 101 is general education, not financial, tax, legal or investment advice, and nothing here is a recommendation to buy or sell anything. Examples use made-up numbers. Rules, limits and rates change, so confirm current details with official sources and consider talking to a qualified professional about your own situation.
A three-digit number quietly decides how much you pay for apartments, cars and loans. Here is how to make it work for you.
The short version- Your credit score summarizes how reliably you repay what you borrow.
- Paying on time and keeping balances low matter most.
- Use a card like a debit card: only charge what you can pay in full.
The report card for borrowing
A credit score is a number, commonly between 300 and 850, that lenders use to judge how risky it is to lend to you. It is built from your credit reports kept by Equifax, Experian and TransUnion. In the U.S. you can check your reports for free at annualcreditreport.com.
What moves it
| Factor | In plain English |
|---|
| Payment history | Do you pay on time? Usually the biggest factor. |
| Utilization | How much of your limit you use. Lower is generally better; many guides suggest well under 30%. |
| Age of accounts | Longer history helps. |
| Mix and new credit | Smaller factors; many applications at once can cause small dips. |
Your first card
Common starting points: a student card, a secured card (a refundable deposit becomes your limit), or becoming an authorized user on a trusted family member's account. Compare annual fees, interest rates (APR) and terms on the issuer's own site, and read the fine print.
The golden rules
- Pay the full statement balance every month. Zero interest.
- Never miss a due date. Autopay helps.
- Keep spending low relative to your limit.
- Carrying a balance does not build credit. That is a myth.
Why interest bites (made-up numbers): A $1,000 balance at 25% APR costs about $250 a year if left alone. High-interest debt can cancel out gains from investing, so pay it down first.
