Understanding Credit Scores: What Affects Them and How to Improve Yours

Your credit score plays a crucial role in your financial life. Whether you’re applying for a mortgage, a car loan, or even a credit card, lenders use your credit score to determine your creditworthiness. A higher credit score not only increases your chances of getting approved for loans but can also lead to lower interest rates and better terms. If you’re new to credit scores or want to understand how to improve yours, this guide will walk you through what affects your credit score and offer practical steps to boost it.

1. What is a Credit Score?

A credit score is a three-digit number that represents your credit risk based on your credit history. Lenders, landlords, and even some employers use your credit score to assess how responsible you are with borrowing and repaying money. The most common credit scoring model is the FICO score, which ranges from 300 to 850. Higher scores indicate lower risk to lenders, while lower scores suggest higher risk.

Credit score ranges:

  • Excellent: 800 – 850
  • Very Good: 740 – 799
  • Good: 670 – 739
  • Fair: 580 – 669
  • Poor: 300 – 579

Pro tip:

  • Aim for a credit score of at least 670 to qualify for better loan terms and lower interest rates. A score above 740 will put you in an excellent position for most financial products.

2. What Affects Your Credit Score?

Several factors contribute to your credit score, and understanding these can help you make smarter financial decisions. While different scoring models may weigh factors slightly differently, the following are the most commonly considered elements:

a. Payment History (35%)

Your payment history is the most significant factor affecting your credit score. It reflects whether you’ve paid your past and current credit obligations on time. Late payments, collections, or defaults will negatively impact your score.

How to improve it:

  • Pay all your bills on time, including credit cards, loans, and utility bills. Set up automatic payments or reminders to ensure you don’t miss due dates.

b. Credit Utilization (30%)

Credit utilization refers to the percentage of your available credit that you’re currently using. It’s calculated by dividing your total credit card balances by your total credit limits. The lower your credit utilization, the better it is for your score.

How to improve it:

  • Keep your credit card balances below 30% of your credit limit. For example, if you have a credit card with a $10,000 limit, try to keep your balance below $3,000.

c. Length of Credit History (15%)

The longer you’ve had credit, the better. This factor considers the age of your oldest account, your newest account, and the average age of all your accounts. A longer credit history generally improves your score.

How to improve it:

  • Avoid closing old credit accounts, even if you’re not using them frequently. Keeping them open can help improve the average age of your accounts.

d. Credit Mix (10%)

Your credit score benefits from having a mix of different types of credit, such as credit cards, auto loans, mortgages, and installment loans. A diverse credit mix shows that you can responsibly manage different kinds of credit.

How to improve it:

  • If possible, maintain a healthy mix of revolving credit (like credit cards) and installment credit (like car loans or mortgages). However, don’t open new accounts just to diversify—only take on debt if necessary.

e. New Credit (10%)

Opening several new credit accounts in a short period can lower your score. Each time you apply for credit, a hard inquiry is recorded on your credit report, which can temporarily ding your score.

How to improve it:

  • Limit new credit applications to only when necessary. Too many inquiries in a short time can signal financial instability to lenders.

3. How to Check Your Credit Score

It’s important to regularly check your credit score to understand where you stand and monitor for any errors that could hurt your score. You can check your score for free through a variety of services, or by requesting a free annual credit report.

Where to check your credit score:

  • Credit card issuers and banks: Many offer free access to your credit score as a benefit of having an account.
  • Credit bureaus: You can request a free credit report once a year from the three major credit bureaus—Equifax, Experian, and TransUnion—at AnnualCreditReport.com. While this report doesn’t show your score, it will give you detailed information about your credit history.
  • Third-party apps: Services like Credit Karma and Credit Sesame offer free access to your credit score and credit monitoring.

Pro tip:

  • Check your credit report regularly to ensure all the information is accurate. If you spot errors, dispute them with the credit bureau to have them corrected.

4. How to Improve Your Credit Score

If your credit score isn’t where you’d like it to be, don’t worry—there are several steps you can take to improve it over time. Improving your credit score takes patience and consistency, but with a plan in place, you can see progress.

a. Pay Your Bills on Time

As payment history makes up the largest portion of your credit score, consistently paying your bills on time is the most effective way to improve it. Even one late payment can have a significant impact, especially if it goes 30 days past due and is reported to the credit bureaus.

Actionable steps:

  • Set up automatic payments or calendar reminders for your due dates to ensure you never miss a payment.
  • If you’ve missed a payment, pay it as soon as possible—late payments affect your score less the sooner they’re resolved.

b. Lower Your Credit Utilization

As mentioned earlier, credit utilization refers to how much of your available credit you’re using. Lowering this percentage can give your credit score a quick boost.

Actionable steps:

  • Pay down credit card balances as much as possible, particularly on high-interest accounts.
  • If you can, ask your credit card issuer for a credit limit increase. This increases your available credit, reducing your utilization percentage (but avoid using the extra credit if possible).

c. Keep Old Accounts Open

The length of your credit history influences your credit score, so it’s beneficial to keep older accounts open, even if you’re not using them regularly. Closing older accounts can shorten your credit history and reduce your total available credit.

Actionable steps:

  • Keep older accounts open unless they have high annual fees. If you don’t use them often, consider making small purchases and paying them off to keep the account active.

d. Diversify Your Credit Mix

Having a mix of credit accounts, such as credit cards, personal loans, and car loans, can boost your credit score. It shows lenders that you can manage various types of credit responsibly.

Actionable steps:

  • If you have only credit cards, consider diversifying with a small personal loan or credit-builder loan. However, don’t take on unnecessary debt—only apply for new credit if you need it.

e. Limit New Credit Applications

Each time you apply for a new line of credit, a hard inquiry is placed on your credit report. Too many hard inquiries in a short period can lower your credit score, as it signals to lenders that you may be taking on too much debt.

Actionable steps:

  • Only apply for new credit when absolutely necessary.
  • When shopping for large loans, like a mortgage or car loan, try to keep all applications within a 14- to 45-day window (depending on the credit scoring model) to minimize the impact on your score.

f. Dispute Errors on Your Credit Report

Errors on your credit report, such as incorrect account information or fraudulent activity, can lower your credit score unnecessarily. Regularly review your credit report to spot any inaccuracies.

Actionable steps:

  • If you find an error, file a dispute with the credit bureau to have it corrected. You can usually do this online, and the bureau is required to investigate and respond within 30 days.
  • Check your credit report from each of the three major bureaus (Equifax, Experian, and TransUnion) to ensure accuracy across the board.

g. Be Patient and Consistent

Improving your credit score takes time, especially if you’ve had late payments or high credit utilization in the past. The key is to stay consistent in your efforts and practice good credit habits over the long term.

Actionable steps:

  • Focus on small, consistent improvements, like making on-time payments and keeping balances low. Over time, these efforts will build a stronger credit profile.

5. How Long Does It Take to Improve Your Credit Score?

The time it takes to improve your credit score depends on your starting point and the actions you take. Small improvements, like paying down credit card balances or disputing errors, can boost your score in as little as 30 days. More significant improvements, such as rebuilding a history of on-time payments or recovering from a missed payment, can take several months to a year or more.

Pro tip:

  • The sooner you start practicing good credit habits, the quicker you’ll see improvements. Consistency is key!

Understanding what affects your credit score is the first step toward improving it. By focusing on factors like payment history, credit utilization, and the length of your credit history, you can take control of your financial future and work toward a higher score. With patience, discipline, and the tips outlined above, you’ll be well on your way to building a solid credit profile that opens the door to better financial opportunities.
