Your credit score influences whether you are approved for a credit card, a loan or an apartment, and what interest rate you are offered. It can even matter for some insurance pricing and utility deposits, depending on where you live and the provider. Yet many people only think about their score when they are about to apply for something. Building good credit is mostly about consistent, unglamorous habits practiced over months and years. This guide explains what a credit score is, what influences it and how to move it in the right direction.
The information here refers to the U.S. credit system. Other countries use different reporting systems and scoring models.
Credit Reports vs. Credit Scores
A credit report is a record of your credit history compiled by a credit bureau. It lists your accounts, balances, payment history, inquiries and public records such as certain collections. The three nationwide credit bureaus are Equifax, Experian and TransUnion. A credit score is a number calculated from the information in your report using a scoring model. According to the Consumer Financial Protection Bureau (CFPB), most credit scores range from 300 to 850, and a higher score usually makes it easier to qualify for a loan and may result in a better interest rate.
The CFPB also stresses that each score depends on the data used to calculate it, and that it may differ depending on the scoring model, the source of the data and even the day it was calculated. That is why you have many scores rather than one, and why you should not panic over small differences between them.
What Goes Into a Credit Score
Scoring companies publish the broad categories they consider, though not their exact formulas. The main categories are:
| Factor | What it measures | How to help your score |
|---|---|---|
| Payment history | Whether you pay on time; late payments, collections and similar events | Pay every bill by the due date; use autopay |
| Amounts owed | How much you owe, including credit utilization on cards | Keep balances low relative to limits |
| Length of credit history | Age of your oldest account and average age of accounts | Keep older accounts open when practical |
| New credit | Recent applications and newly opened accounts | Apply only when needed |
| Credit mix | Variety of account types, such as cards and installment loans | Do not take loans just to diversify |
The CFPB's educational materials note that payment history is the biggest factor in FICO scores, making up 35% of the score, and that amounts owed makes up another 30%. Those two categories alone account for roughly two-thirds of a typical FICO score, which is why the advice below focuses on them.
Step 1: Check Your Credit Reports
Before you try to improve anything, find out where you stand. The Federal Trade Commission explains that federal law entitles you to a free report from each of the three bureaus every 12 months, and that the bureaus have permanently extended a program that lets you check each report once a week for free. The only authorized site is AnnualCreditReport.com. Beware of copycat sites that advertise “free” reports but enroll you in paid services.
When you review your reports, look for:
- Accounts you do not recognize, which may signal identity theft.
- Payments marked late that you made on time.
- Incorrect balances or credit limits.
- Old accounts that should have aged off your report.
- Misspelled names, wrong addresses or mixed-up information.
If you find an error, you can dispute it with the credit bureau and with the company that supplied the information. Keep copies of everything you send. Fixing an error is one of the fastest ways to improve a score, but there is no guarantee that any given dispute will change the result.
Step 2: Make Every Payment on Time
Payment history is the heaviest factor, and it is the one you can control most directly. A single payment that is 30 days or more late can be reported to the bureaus and can stay on your report for years. Practical safeguards include:
- Set up autopay for at least the minimum payment on every account.
- Choose a due date that aligns with your payday. Many issuers will move it on request.
- Set calendar reminders for bills that cannot be automated.
- If you fall behind, contact the lender before the due date to ask about hardship options.
If you have already missed payments, the most helpful thing you can do is bring the account current and then stay current. Recent behavior generally counts more than older behavior, so a run of on-time payments gradually reduces the impact of past mistakes.
Step 3: Reduce Your Credit Utilization
Credit utilization is the percentage of your available revolving credit that you are using. If you have a $4,000 combined limit and owe $2,000, your utilization is 50%. The CFPB notes that experts advise keeping your use of credit at no more than about 30 percent of your total limit, and lower is generally better for scores.
Ways to lower utilization include paying down balances, making extra payments before the statement closing date, spreading spending across cards, and requesting a credit limit increase, which lowers utilization if your balance stays the same. Be aware that some issuers use a hard inquiry for limit increases, so ask first. Avoid the temptation to close cards you have paid off. Closing an account reduces your total available credit, which may raise your utilization, and can eventually reduce your average account age.
Step 4: Build a History If You Have None
People with little or no credit history are sometimes called credit invisible. The CFPB lists several ways to start building a history. Common options include:
Secured Credit Cards
You put down a refundable deposit that generally becomes your credit limit. As long as the issuer reports your activity to all three bureaus and you pay on time, this can establish a record. See our comparison of secured and unsecured credit cards.
Credit-Builder Loans
Offered by some credit unions and community lenders, these loans hold the borrowed money in an account while you make payments, and release it at the end. Payments are reported, which builds history. Check fees and whether the lender reports to all three bureaus.
Becoming an Authorized User
A family member or trusted friend with a well-managed card can add you as an authorized user. Depending on the issuer and scoring model, the account history may appear on your report. It also ties your record to someone else's habits, so choose carefully.
Reporting Rent and Other Payments
Some services report on-time rent or utility payments. Whether these are used in the scores lenders look at varies, so treat them as a possible bonus rather than a plan on their own.
Step 5: Apply for New Credit Sparingly
Each time you apply for credit, the lender typically requests your report, creating a hard inquiry. A few inquiries have a small and temporary effect. Many in a short time can suggest financial stress to lenders. New accounts also lower the average age of your accounts. Apply when you have a real need and a good chance of approval. Rate shopping for a single loan type within a short period is generally treated as one inquiry by many scoring models, but the window varies by model, so keep your shopping tightly grouped.
How Long Does It Take?
Some changes can show up within one or two billing cycles, such as a lower utilization ratio or the correction of an error. Others take much longer. Negative marks generally stay on your reports for a fixed number of years, with most late payments and collections remaining for up to seven years and certain bankruptcies for up to ten. Their impact tends to fade as time passes and new positive information accumulates. Building an excellent record from scratch usually takes years, not weeks. Be skeptical of anyone who promises to raise your score quickly for a fee.
Protecting Your Credit From Fraud
Identity theft can damage your credit without any action on your part. The FTC notes that a credit freeze is free to place or lift, does not affect your credit score and, while in place, prevents new credit accounts from being opened in your name. To place a freeze, you contact each of the three bureaus. An initial fraud alert is also free, lasts one year and tells businesses to check with you before opening new credit. If you are a victim of identity theft, report it at IdentityTheft.gov to get a recovery plan. Regular monitoring of your reports helps you catch problems early.
Myths That Hold People Back
“Carrying a balance helps my score.”
It does not. You build credit by using your card and paying on time. Carrying a balance only adds interest costs, and higher utilization can hurt.
“Checking my own credit lowers my score.”
Checking your own reports or scores is a soft inquiry and does not affect your score.
“Income is part of my credit score.”
Income is not included in credit reports or in standard credit scores, although lenders may consider it separately when deciding how much to lend.
“Credit repair companies can remove accurate negative items.”
Accurate information generally remains on your report until it ages off. You can dispute errors yourself for free.
A 12-Month Improvement Plan
- Month 1: Pull all three reports, dispute errors and turn on autopay everywhere.
- Months 2 to 3: Build a small buffer so that unexpected expenses do not cause late payments. Start paying cards down before statement dates.
- Months 4 to 6: Keep utilization under about 30%, or lower if you can. If you have no cards, open one secured or starter account and use it for a small recurring bill.
- Months 7 to 12: Keep every payment on time, avoid new applications unless needed and re-check your reports at the end of the year.
Frequently Asked Questions
What is a good credit score?
Lenders define ranges differently, but higher scores generally lead to better terms. Rather than focusing on a label, aim for consistent on-time payments and low utilization, and ask lenders what score range they use for specific products.
How fast can I raise my score?
It depends on your starting point. Fixing errors and lowering utilization can produce changes within a month or two, but recovering from serious delinquencies takes longer. There is no honest guarantee of a specific gain in a specific time.
Do I need a credit card to build credit?
Not necessarily. Installment loans, credit-builder loans and reported rent may also contribute. A credit card is simply one of the most flexible ways to demonstrate on-time payments.
Does closing an old credit card hurt my score?
It can, mainly by reducing your total available credit and eventually shortening your average account age. If a card has no annual fee, keeping it open with occasional small purchases is often reasonable.
Are free score services accurate?
Many are useful for tracking trends, but the score they show may come from a different model than the one a lender uses. Use them for direction rather than precision.
Conclusion
A strong credit score is the by-product of a few habits: paying on time, keeping balances low, borrowing only when you need to and giving your accounts time to age. Check your reports regularly, fix errors, protect your identity and ignore promises of overnight fixes. With patience the numbers follow, and better credit can translate into lower borrowing costs.
