A credit score is a three-digit number, usually from 300 to 850, that estimates how likely you are to repay borrowed money. Lenders use it to decide whether to approve you and what interest rate to charge. It isn't a measure of wealth or character — it's a risk prediction built from your borrowing history.
The five factors behind your score
The most widely used models weigh roughly these ingredients:
- Payment history (~35%) — do you pay on time? The single biggest factor. One missed payment can sting for years.
- Credit utilization (~30%) — how much of your available credit you're using. Keeping balances well under ~30% of limits helps; lower is better.
- Length of credit history (~15%) — older accounts and a longer average age look more stable.
- Credit mix (~10%) — a blend of types (cards, installment loans) can help modestly.
- New credit (~10%) — many applications in a short window (hard inquiries) can ding you temporarily.
Checking your own score is a soft inquiry and never hurts it. Applying for new credit triggers a hard inquiry, which can cause a small, temporary dip. So monitor your score freely — it's the applications, not the checking, that count.
What counts as a "good" score
Bands vary by model, but as a rough guide: high 600s is fair-to-good, the 700s is good-to-very-good, and the 800s is excellent. The practical payoff is money: a higher score typically means lower interest on cards, car loans, and mortgages — sometimes tens of thousands of dollars over a loan's life.
How to improve it
- Pay every bill on time — automate the minimum so you never miss.
- Lower your utilization — pay down balances, or pay before the statement closes.
- Keep old accounts open — closing them can shorten your history and raise utilization.
- Apply sparingly — space out new credit to limit hard inquiries.
- Check your reports — dispute errors; mistakes are more common than people expect.
The bottom line
Your credit score is a repayment-risk prediction, and you control most of what feeds it. Pay on time, keep balances low, and let your accounts age — do that consistently and the number takes care of itself, quietly saving you money every time you borrow.
