Credit Scores

A credit score is a number that lenders use to estimate how likely you are to repay what you borrow. It is built from your borrowing history and can affect whether you are approved for credit and what interest rate you are offered.

Quick definition

A credit score is a number, commonly shown on a scale from 300 to 850, that summarizes how reliably you have repaid borrowed money.

Why it matters

Your credit score can shape some of the biggest costs in your life. Lenders often use it to decide whether to approve a loan or card and what interest rate to charge, and a higher score can mean lower borrowing costs.

It can also matter beyond loans. Landlords, insurers, and utility companies sometimes look at credit information, so understanding your score helps you see how others may view your financial reliability.

Step by step

  1. 1

    Know what the score measures

    A credit score is a snapshot of your borrowing history. It does not measure your income or savings, only how you have managed credit such as cards and loans over time.

  2. 2

    Understand the main factors

    Scores are generally driven most by paying on time and by how much of your available credit you use, followed by the length of your history, the mix of credit types, and recent applications.

  3. 3

    Pay every bill on time

    Payment history is usually the largest factor. Paying at least the minimum by the due date, every time, is the single most reliable way to support your score.

  4. 4

    Keep balances low

    Using only a small share of your available credit tends to help. Carrying high balances relative to your limits can weigh on your score, even if you pay on time.

  5. 5

    Check your credit report

    Review your credit report for errors, since mistakes can drag down a score. You are entitled to free copies of your report, and disputing genuine errors can help.

Practical example

How credit use can affect a score

Suppose you have a credit card with a $1,000 limit. Using $100 of it, then paying the balance, keeps your usage low, which lenders generally view well. Letting the balance climb toward the full $1,000 raises your usage, which can weigh on your score even when you make payments. This is a simplified illustration of one factor, not the whole picture.

Common mistakes

  • Missing payment due dates, which tends to affect a score more than almost anything else.
  • Using a large share of your available credit and carrying high balances month to month.
  • Closing your oldest account, which can shorten your credit history.
  • Assuming checking your own report or score in the normal way harms it, which is not how it works.

How to apply it

Practical pointers for learning, not advice to buy or sell anything.

  • Set up automatic minimum payments or reminders so you never miss a due date.
  • Aim to keep your balances low relative to your credit limits.
  • Review your credit report regularly and dispute any genuine errors you find.
  • Open new accounts only when you need them, rather than several at once.

Frequently asked questions

What is a good credit score?

Scoring models differ, but on the common 300 to 850 scale, higher is generally seen as better, and scores in the upper ranges are often viewed favorably by lenders. The exact cutoffs vary by lender and by the scoring model used.

What affects my credit score the most?

For most common scoring models, paying on time and how much of your available credit you use are the biggest factors. The length of your credit history, the mix of credit types, and recent applications also play a role.

How can I improve my credit score?

The most reliable steps are paying every bill on time, keeping your balances low relative to your limits, and checking your credit report for errors. Improvement usually takes time and consistency rather than a single quick fix.

Does checking my own credit hurt my score?

Checking your own credit report or score in the normal way is treated as a soft inquiry and does not lower it. Hard inquiries, which happen when a lender reviews your credit for a new application, can have a small, usually temporary effect.

How long does it take to build credit?

Building credit is gradual. On-time payments and low balances tend to help over months and years, and there is no instant way to create a long, positive history. Patience and consistency are the main drivers.
