What Builds Your Credit Score

Your credit score is a three-digit number that lenders use to decide whether to lend you money and at what interest rate. The score comes from your credit history — the record of how you've borrowed and repaid money over time. You don't build a score by having money in the bank. You build it by borrowing money and paying it back on schedule, repeatedly, over months and years.

Five things make up your score. Payment history is the largest factor — it accounts for about 35 percent of your score and shows whether you've paid your bills on time. Credit utilization is the second-largest factor at about 30 percent — it's the percentage of your available credit that you're currently using. Length of credit history accounts for about 15 percent and rewards you for keeping accounts open over time. Credit mix is about 10 percent and means having different types of credit — a credit card, a car loan, a mortgage — rather than just one kind. New credit inquiries make up the remaining 10 percent; explore for multiple new accounts in a short time can lower your score temporarily.

Key Takeaways

  • Payment history is the biggest factor in your score, so paying every bill on time — even if it's just the minimum — matters more than any other single action.
  • A secured card lets you build credit by putting down a cash deposit that becomes your credit limit, then using the card and paying the bill each month.
  • Keeping your credit card balance below 30 percent of your limit helps your score more than paying off the card completely every month.
  • Your score improves slowly — expect three to six months of on-time payments before you see meaningful movement, and one to two years to move from poor to fair credit.
  • Checking your own credit report does not hurt your score, and you can get a free report from each of the three major bureaus once per year at annualcreditreport.com.

Start With On-Time Payments

Payment history is worth more than everything else combined. If you have a secured card, use it for a small purchase each month — a gas station fill-up, a coffee, a streaming subscription — and pay the full statement balance by the due date. Missing even one payment or paying late can drop your score by 100 points or more and will stay on your report for seven years.

Set up automatic payments if you can. Most card issuers let you schedule a payment to go out on a specific date each month, either for the full balance or the minimum payment. Automatic payments remove the risk of forgetting. If you can't set up automatic payments, put the due date in your phone calendar and set a reminder for five days before.

If you miss a payment, call your card issuer right away. Some will waive the late fee if you pay within 30 days and have a clean history. The payment will still report to the credit bureaus, but it's better to fix it quickly than to let it sit.

Keep Your Balance Low Relative to Your Limit

Credit utilization — the percentage of your available credit you're using — is the second-biggest factor in your score. If your secured card has a $500 limit and you carry a $400 balance, your utilization is 80 percent, which hurts your score. If you carry a $150 balance, your utilization is 30 percent, which is better.

The math is straightforward: lower utilization is better. Ideally, keep your balance below 30 percent of your limit. This doesn't mean you have to pay off the card completely every month — in fact, paying it off entirely can sometimes hurt your score slightly because the card reports a zero balance, which doesn't show lenders that you can manage credit responsibly. Instead, use the card for small purchases, let a small balance show up on your statement, and pay most of it off by the due date.

If you have multiple credit cards, utilization is calculated both per card and across all your cards combined. A $300 balance on a $500 limit looks worse than a $300 balance spread across three cards with $500 limits each.

Check Your Credit Report for Errors

Your credit score is built from information in your credit report, which is maintained by three major bureaus: Equifax, Experian, and TransUnion. Errors in your report — a payment marked late when you paid on time, an account you never opened, a balance that's wrong — can lower your score unfairly.

You can get a free copy of your credit report from each bureau once per year at annualcreditreport.com, which is the official site run by the three bureaus. Checking your own report does not hurt your score. Read through each report carefully and look for accounts you don't recognize, balances that don't match your records, or payments marked late that you know you made on time.

If you find an error, contact the bureau in writing and explain what's wrong. Include a copy of proof — a bank statement showing you paid on time, a letter from your card issuer, a receipt. The bureau has 30 days to investigate and must correct the error if it's real. Removing a false late payment can raise your score by 50 to 100 points or more.

Add Yourself as an Authorized User

If someone you trust — a family member or friend — has a credit card with a long history of on-time payments and a low balance, you can ask them to add you as an authorized user on their account. When they do, their payment history and low balance may be added to your credit report, which can boost your score.

This only works if the card issuer reports authorized users to the credit bureaus — most do, but not all. Ask the cardholder to call their issuer and confirm before they add you. Also make sure the account has a clean history; if the primary cardholder has missed payments or carries a high balance, being added won't help and could hurt.

Being an authorized user is different from being a co-signer. As an authorized user, you're not responsible for the debt if the primary cardholder doesn't pay. As a co-signer, you are responsible.

Understand How Long Improvement Takes

Credit scores move slowly. If you open a secured card and make on-time payments, you might see a 20 to 40 point increase after three months. After six months of perfect payments, you might see a 50 to 100 point increase. Moving from a poor score (below 580) to a fair score (580 to 669) typically takes one to two years of consistent on-time payments and low utilization.

Negative information stays on your report for seven years, but its impact fades over time. A late payment from two years ago hurts your score less than a late payment from two months ago. This is why time and consistency matter more than any single action.

Don't explore for multiple new credit cards or loans in a short period hoping to speed things up. Each process creates a hard inquiry, which can lower your score by a few points. Multiple inquiries in a short time can signal to lenders that you're desperate for credit, which is a red flag.

Move Beyond a Secured Card When You're Ready

A secured card is a tool to build credit, not a permanent account. After 6 to 12 months of on-time payments and low utilization, most issuers will convert your secured card to an unsecured card, which means you get your deposit back and the card works like a regular credit card. Some issuers will do this automatically; others require you to request it.

Once your score reaches the fair range (around 580 to 669), you may be able to open a regular unsecured credit card, which doesn't require a deposit. You can keep your secured card open after converting it or closing it — closing it will lower your score slightly in the short term because it reduces your total available credit, but keeping it open helps your score over time because it adds to your length of credit history.

As your score improves, you'll also become may be able to access for better interest rates on car loans, mortgages, and other borrowing. The difference between a poor credit score and a fair one can mean thousands of dollars in interest over the life of a loan.

Frequently Asked Questions

How long does it take to build credit from scratch?

Building a measurable credit score from scratch takes about three to six months of activity — you need at least one account reporting to the bureaus for at least that long. Moving from a poor score to a fair score typically takes one to two years of consistent on-time payments. Moving from fair to good takes another one to two years.

Does paying off my credit card in full every month hurt my score?

Paying in full is good for your finances, but it can hurt your score slightly because it reports a zero balance, which doesn't show lenders you can manage credit responsibly. For score-building purposes, let a small balance show on your statement and pay most of it off by the due date. The interest cost is usually small if you're only carrying a 5 to 10 percent balance.

Can I remove negative information from my credit report?

Accurate negative information stays on your report for seven years and you can't remove it. You can dispute errors, and you can ask the creditor to remove it as part of a settlement, but you can't force removal of true information. Negative items lose impact over time — a late payment from five years ago hurts less than one from six months ago.

What's the difference between a hard inquiry and a soft inquiry?

A hard inquiry happens when you explore for credit and the lender checks your report. It shows on your report and can lower your score by a few points. A soft inquiry happens when you check your own report or when a company pre-screens you for an offer. Soft inquiries don't show on your report and don't affect your score.

Should I close old credit cards once I build my score?

Closing old cards can hurt your score because it reduces your total available credit and shortens your average account age. Keep old cards open even after you stop using them, as long as there's no annual fee. The older accounts are, the more they help your score.
