Credit basics, explained calmly.

No gimmicks, no promises, nothing to buy — just how credit scores actually work, in plain language.

What a credit score is

A credit score is a three-digit number — usually between 300 and 850 — that summarizes how you've handled borrowed money. Lenders use it to guess how likely you are to repay. It isn't a grade of your worth, your income, or your intelligence. It's a repayment track record, compressed into a number.

The five factors (FICO publishes these)

35%

Payment history

Paying on time, every time, matters more than anything else.

30%

Utilization

How much of your available credit you're using — lower is better.

15%

Length of history

The average age of your accounts — old accounts are your friends.

10%

New credit

Many new applications in a short time can lower the number.

10%

Credit mix

Having different kinds of accounts, handled well, over time.

Common myths

"Checking my own score hurts it." — False.Checking your own score or report is a soft inquiry. It never affects the number.

"Carrying a balance helps." — False.You can pay in full every month and build history. Interest paid buys you nothing.

"Closing old cards cleans things up." — Usually false.Closing an old account can shorten your history and raise your utilization at the same time.

"A higher income means a higher score." — False.Income is not part of the formula. A modest income with on-time payments beats a big income with late ones.

The habits behind healthy credit

Pay every bill on time — automate at least the minimums so a due date can never surprise you.
Keep card balances low relative to their limits.
Keep your oldest accounts open when it costs you nothing.
Apply for new credit rarely, and only when you need it.
Read your own reports — they're free, and errors are yours to catch.
