Credit Score 101: What Are the 5 Factors that Affect Your Credit Score?

Money and credit card

Credit ratings like FICO scores were created to help lenders identify creditworthy borrowers. They wanted to make sure that people can repay their loans on time. 

In response, credit bureaus formulated credit scoring models to assign scores lenders can use to assess borrowers easily. There have been new iterations of the scoring model, like VantageScore 3.0, but the factors and scoring ranges remain similar.


Payment History

The heaviest factor of your credit score is your payment history, occupying 35% of the rating. A record of diligent payments guarantees lenders that you can repay them on time, too. If they do, the bureaus raise their credit ratings. 

Otherwise, they are deducted from peoples’ credit scores. 

Making punctual payments is one of the best ways to improve your credit rating. Financial advisors often recommend it as it enhances the factor with the most impact on credit score. 

Complete debt payments diligently for a few months to eventually raise your credit. They assure lenders that you can pay on time, so they’re more likely to offer better loans.


Credit Utilization

Credit bureaus measure your credit use and your available credit. This ratio, credit utilization, accounts for 30% of your credit score. If you have too many unpaid balances, this credit score factor drops along with your rating. 

As a general rule of thumb, keep your credit utilization below 30% to avoid deductions.

You can minimize utilization every month by paying twice. This lowers your unpaid amount and credit limit, minimizing your credit utilization. In addition, you can request to expand your credit limit to lower the utilization ratio. 

Make sure to spend wisely, as you can be tempted to fill the increased limit.


Credit History Length

The length of your credit history comprises 15% of your credit score. It considers the average age of your accounts and the age of your recent and past accounts. 

Also, it includes the duration of time your accounts have been active and the length of time since you’ve used each account. Lenders prefer borrowers with extensive records as those yield better results from scoring models.

Opening too many new accounts can hurt credit scores. Only open new lines of credit when necessary to maintain your credit standing. Also, avoid closing accounts even if you aren’t using them. 

A closed account will not be considered in your credit report after ten years, so your credit rating could eventually decrease.


Credit Mix

Your rating can gradually increase if you have various kinds of credit, such as student loans and car loans. It shows that you can handle multiple loans, assuring lenders you can handle theirs. 

If you only have one kind of debt, this factor may not boost your score considerably. In this 101 guide, remember that this accounts for only 10% of your credit score, so you should concentrate on the larger factors.


New Credit

Your new credit accounts comprise the last 10% of your credit score. Opening new lines of credit prompts your bank to perform a hard credit inquiry. This often causes credit scores to decrease since it could indicate poor personal finance management. 

To measure this factor, the Fair Isaac Corporation checks the number of hard inquiries you’ve made within 12 months.

How Is Your Credit Score Calculated?

Impact on credit score

Credit score 101 involves knowing how to calculate the credit score. This is calculated based on several key components from your credit report. Here’s a breakdown:


Payment History (35%)

This is the most significant factor in determining your credit score. It checks if you’ve paid past credit accounts on time, including credit cards, loans, and mortgages. Missed or late payments can negatively affect your score, indicating a higher risk to lenders. Furthermore, serious delinquencies like bankruptcies, foreclosures, and collections can have even more severe impacts and take longer to recover from. Maintaining a consistent record of on-time payments is crucial for building and keeping a strong credit score.


Amounts Owed (30%)

This factor evaluates how much you owe and compares it to your credit limits, known as your credit utilization rate. High utilization can signal risk and lower your score because it may indicate that you are over-reliant on credit and have trouble paying off your debts. Ideally, experts recommend the utilization rate to be below 30% of your total available credit . Lenders view this positively. Additionally, paying down installment loans positively affects your score, demonstrating your ability to manage and repay debt over time.


Length of Credit History (15%)

Longer credit histories are generally considered less risky. They offer more data on managing credit over an extended period. This factor considers the age of your oldest account, the average age of all your accounts, and when each account was last used. A well-established credit history suggests stability and predictability, which are favorable to lenders. Therefore, keeping older accounts open, even if they are not used frequently, can be beneficial for maintaining a good credit score.


New Credit (10%)

Opening several new credit accounts quickly can be considered risky behavior, especially if you don’t have a long credit history. This activity can lower your average account age, negatively impacting your credit score. Lenders may interpret this as financial instability or taking on more debt than you can handle. To maintain a healthy credit score, you should apply for new credit sparingly and only as needed, ensuring you can manage additional credit without compromising your financial stability.


Credit Mix (10%)

This factor evaluates your various credit accounts, such as credit cards, mortgages, and installment loans. A diverse mix of different types of credit can positively affect your score, demonstrating your ability to manage various forms of credit responsibly. Lenders like to see that you can handle both revolving credit, like credit cards, and installment loans, like car loans or mortgages, because it suggests financial maturity and reliability. Therefore, maintaining a balanced mix can contribute to a higher credit score, providing you manage each type of credit well.


By understanding these 101 factors, you can improve your credit score by paying bills on time, keeping balances low, and only opening new accounts when necessary.

What Will Bring Down Your Credit Score?

Lower credit score

Now that we’ve discussed how to raise your credit rating, we’ll explain how you might be bringing it down. If you’ve been doing the opposite of our earlier recommendations, your credit score could have declined recently. 

Adding debt, repaying late, and performing hard inquiries are typical causes of bad credit. Worse, your credit can crash if someone opens accounts under your name.


Late Payments

We’ve mentioned that payment history has the most impact on credit score, and late payments cause deductions from your credit rating. Remember, it’s 35% of the rating, so prioritize this when improving credit. 

You must build a consistent record of punctual payments to raise your score.


Credit Score 101: High Credit Card Utilization

Credit bureaus contrast the amount you owe to your available credit to check how likely you can repay them on time. You should keep utilization below 30% to avoid credit deductions. 

If you’ve been borrowing too much, your credit score could be lowered. This will cause your credit use to soar and your credit rating to drop eventually.


Hard Inquiries

Also, you may have asked too many hard questions because of excessive credit use. Banks need to perform these inquiries to open your new account after all. 

As mentioned, you should use credit only when necessary to maintain your score. Despite being a mere 10% of your rating, it can still help you earn good credit.


Identity Theft

If someone steals your identity, they can freely open lines of credit under your name. Impostors could shackle you with huge debts and destroy your credit rating. 

To avoid identity theft, you should keep your financial details secure. Review your credit reports regularly, and contact the Federal Trade Commission if you suspect identity theft.

How to Improve Your Credit Score

Credit score

Improving your credit score is a strategic process in this 101 guide that can open up better financial opportunities. Here’s how you can enhance your credit standing:


Credit Score 101: Pay Your Bills on Time

Since payment history is a significant component of your credit score, consistently paying your bills on time is the most effective way to improve your score. Setting up automatic payments or calendar reminders can help ensure you never miss a due date. Furthermore, maintaining a track record of on-time payments can gradually heal past credit wounds, showing lenders that you’re a responsible borrower. This consistent behavior not only boosts your credit score but also enhances your credibility with financial institutions, potentially leading to better loan offers and credit limits in the future.


Reduce Your Debt

Pay down your credit card balances and other loans. Aim to keep your credit utilization ratio under 30% of your available credit, as higher ratios can negatively impact your score. Reducing your overall debt improves your credit utilization and lessens your financial burden, making it easier to manage unexpected expenses. Regularly applying extra payments to your highest-interest debts can accelerate this process, saving you money on interest over time. This deliberate approach to debt reduction can significantly enhance your credit profile and increase your financial flexibility.


Keep Old Accounts Open

The length of your credit history affects your score, so keep older credit accounts open even if you don’t use them frequently. This helps increase the average age of your accounts, which can positively influence your credit score. Older accounts add stability to your credit report, demonstrating a long-term, responsible credit management history to lenders. Occasionally, using these older accounts for small purchases you can pay off immediately is also beneficial. This keeps the accounts active and prevents them from being closed by the issuer due to inactivity. This strategy maintains your credit history depth without adding financial strain.


Limit New Credit Inquiries

Every time you apply for new credit, it can result in a hard inquiry, which may temporarily lower your credit score. Please be careful about applying for new credit and only do so when necessary. Frequent hard inquiries signal to lenders that you might be taking on more debt than you can handle, making you appear risky. Instead, you should plan your credit applications strategically, such as when looking for a mortgage or car loan, and avoid unnecessary credit checks. Spacing out applications can help maintain your score and ensure it recovers from any dips caused by those inquiries.


Diversify Your Credit Mix

A mix of different types of credit (e.g., credit cards, mortgages, auto loans) can positively influence your score. This shows lenders that you are capable of managing various types of credit. Demonstrating your ability to handle both revolving credit responsibly (like credit cards) and installment loans (like auto loans and mortgages) can make you a more attractive borrower. This diversity in your credit portfolio improves your credit score and prepares you for more substantial financial undertakings. Additionally, varied credit history can help smooth out potential negative impacts from one type of credit, maintaining a more stable overall credit rating.


Check Your Credit Reports Regularly

Errors in your credit reports can drag your score down. Regularly review your credit reports from the three major credit bureaus (Equifax, Experian, and TransUnion) to ensure accuracy. Dispute any inaccuracies you find. This proactive approach helps protect your credit score from incorrect payment statuses, fraudulent accounts, or outdated information. You are entitled to a free credit report from each bureau once a year through, making it easier to keep tabs on your credit status. Addressing these issues promptly can restore your credit score and safeguard against identity theft and credit fraud.

By following these steps, you can improve your credit score, which can help you secure better future terms for loans and credit.

Frequently Asked Questions

How to check your credit score?

Checking your credit score is straightforward and can be done in several ways. Most credit card companies offer free credit score monitoring to their customers, which you can usually access through your online banking portal. Additionally, you can obtain your credit score from major credit bureaus—Equifax, Experian, and TransUnion—often for free once per year at Annual Credit Report. Some financial websites and apps also offer free credit score services without requiring a subscription. It’s a good practice to check your score regularly to monitor your financial health and spot any potential inaccuracies or fraudulent activities early.

You don’t start with a credit score automatically. Instead, a credit score is generated after you’ve had at least one credit account open for six months or more, as this is the minimum amount of time needed for credit bureaus to assess your activity and produce a score. This first score is based on your initial credit usage, payment history, and other financial behaviors reported to the credit bureaus. Therefore, effectively managing your first credit accounts is crucial for establishing a good initial credit score.

There are several reasons why your credit score might drop. Common causes include missing or late payments, which negatively impact your payment history; high credit utilization rates if you’ve used a large portion of your available credit; closing old credit accounts, which can shorten your credit history; applying for new credit, which results in hard inquiries; or changes to your credit mix. Additionally, inaccuracies or fraudulent activities on your credit report can also lead to a decrease. It’s important to regularly review your credit report to identify and address any of these issues promptly.

To boost your credit score, consistently pay your bills on time since payment history heavily influences your score. Keep credit card balances low relative to their limits, ideally under 30% utilization, to show responsible credit management. Maintain older credit accounts open to extend the length of your credit history, demonstrating stability. Avoid unnecessary new credit applications to minimize hard inquiries, which can temporarily lower your score. Regularly check your credit reports for errors or fraudulent activity, correcting any issues promptly to ensure your score accurately reflects your credit behavior. Following these strategies can help you improve your credit score over time, enabling better financial opportunities.

To boost your credit score using a credit card, always pay your bill on time and aim to keep your balances low—ideally under 30% of your credit limit. Regular, responsible usage shows that you can manage credit effectively, so consider using your card for small purchases and paying off the full amount each month. Additionally, try to pay more than the minimum due whenever possible to decrease your balance quickly and improve your credit utilization ratio. Regularly monitoring your account for accuracy and unauthorized charges also helps maintain a healthy credit profile. By adhering to these practices, you can use your credit card to strengthen your credit history and increase your score.
