Introduction
If you’re trying to build strong financial health, knowing what actually affects credit score is one of the most important steps you can take. Your credit score plays a crucial role in determining whether you can qualify for loans, get approved for credit cards, rent an apartment, or even land a job in some industries. Yet many people don’t fully understand what really moves their credit score up or down.
The good news? Once you learn exactly what affects credit score, you can take simple, focused actions to improve it — and with a stronger credit score, you’ll unlock better interest rates, higher credit limits, and greater financial freedom.
In this article, we’ll break down the 7 biggest factors that influence your credit score — so you’ll know what to watch out for, what to prioritize, and how to take control of your credit rating starting today. Let’s dive in!
1. Payment History: The #1 Factor That Affects Credit Score
When it comes to what affects credit score the most — payment history tops the list. In fact, it typically accounts for about 35% of your overall score. Why? Because lenders want to know if you’ve reliably paid your debts in the past.
Why On-Time Payments Matter Most
Every time you make an on-time payment on your credit cards, loans, or other accounts, you’re proving your creditworthiness. The more consistent your payment history, the stronger your score.
How Late or Missed Payments Damage Your Score
- Even one late payment (30 days past due) can lower your score by 60–100 points
- A pattern of late payments or delinquencies will cause deeper and longer-lasting damage
- Missed payments stay on your credit report for up to 7 years
Tips to Maintain a Perfect Payment Record
- Set up automatic payments or reminders
- Always pay at least the minimum due by the due date
- Stay organized and track your payment due dates across all accounts
2. Credit Utilization Ratio: How Much You Owe vs. Your Credit Limit
Next on the list of what affects credit score is your credit utilization ratio — which usually makes up 30% of your score. This is the percentage of your available credit that you’re currently using.
What Credit Utilization Is and How It Affects Your Score
If you’re using a high percentage of your credit limits, lenders may view you as overextended — which can lower your score, even if you’re making payments on time.
The “Magic Number” Experts Recommend
Experts recommend keeping your credit utilization under 30% — ideally below 10% for the best results. For example:
- If you have a $10,000 credit limit, try to keep balances below $3,000 (or even better, under $1,000).
Simple Ways to Manage and Reduce Your Utilization
- Pay off balances early — before your statement closes
- Ask for a credit limit increase (but don’t take on more debt)
- Spread purchases across multiple cards to lower utilization on each
3. Length of Credit History: Why Time Is on Your Side
Another key factor that affects credit score is the length of your credit history, which contributes about 15% of your score. The longer your history of managing credit responsibly, the better.
How the Age of Your Accounts Affects Credit Score
Credit scoring models look at:
- The age of your oldest account
- The average age of all your accounts
- The age of your newest account
A longer, well-managed credit history shows lenders you have experience handling credit.
Why Closing Old Accounts Can Backfire
Many people close old credit cards thinking it will help their finances — but it can actually hurt your score by:
- Reducing your average account age
- Increasing your credit utilization ratio (by lowering your total available credit)
How to Maintain and Build a Positive Credit Age
- Keep old, well-managed credit cards open — even if you use them occasionally
- Avoid opening too many new accounts in a short period
- Be patient — building credit age takes time but pays off in the long run

4. Types of Credit Used (Credit Mix)
Another important factor that affects credit score is your credit mix, which typically makes up about 10% of your score. It refers to the variety of credit accounts you have, such as:
- Credit cards
- Personal loans
- Car loans
- Mortgages
- Student loans
Why Having Different Types of Credit Affects Your Score
Lenders like to see that you can handle a variety of credit responsibly. A healthy credit mix shows that you can manage both revolving credit (like credit cards) and installment loans (like car loans or mortgages).
The Value of a Healthy Credit Mix
- A well-balanced credit mix may slightly improve your credit score, especially if you’re building credit from scratch.
- It also demonstrates financial maturity to future lenders.
How to Responsibly Diversify Your Credit Profile
- Only open new credit accounts as needed — don’t open accounts just to boost your mix
- Maintain a balance of revolving and installment credit over time
- Focus on managing each account responsibly rather than having too many accounts
5. New Credit Inquiries: How Applications Affect Credit Score
When it comes to what affects credit score, credit inquiries are often misunderstood. Inquiries contribute about 10% of your score and can affect it more than many people realize, especially if you apply for several new accounts at once.
The Difference Between Hard and Soft Inquiries
- Hard inquiries happen when you apply for credit (loan, credit card, mortgage). These can slightly lower your score.
- Soft inquiries occur when you check your own credit or when a lender pre-approves you. These do not affect your score.
How Too Many Hard Inquiries Can Lower Your Score
Each hard inquiry may lower your score by a few points. Multiple hard inquiries in a short period can signal to lenders that you’re taking on too much debt.
How to Manage Credit Applications Strategically
- Only apply for credit when necessary
- Group rate-shopping inquiries (mortgages, auto loans) within a short time frame — most scoring models treat these as one inquiry
- Monitor your credit report to track inquiries
6. Total Debt Owed: How Your Overall Debt Level Affects Credit Score
Another major factor that affects credit score is your total debt owed — beyond just your credit utilization. Lenders look at the total amount you owe across all accounts when assessing your ability to manage new debt.
The Impact of Large Outstanding Debts on Your Rating
- High overall debt can indicate financial strain and make you appear riskier to lenders.
- It may also affect your debt-to-income ratio, which many lenders review alongside your credit score.
Why Paying Down Debt Helps Beyond Just Lowering Utilization
Reducing your total debt not only improves your credit utilization ratio, but also demonstrates responsible credit behavior — helping you gradually raise your score.
Smart Strategies for Managing Debt Responsibly
- Pay more than the minimum on revolving credit balances
- Prioritize high-interest debt first (debt avalanche method)
- Avoid taking on new debt while paying off existing balances
7. Negative Public Records: The Long-Lasting Damage of Collections, Bankruptcies, and More
Among the most damaging factors that affects credit score are negative public records. These include items such as:
- Collections accounts
- Bankruptcies
- Foreclosures
- Tax liens
- Civil judgments
How Serious Public Records Can Devastate Your Credit
Public records can cause your credit score to drop dramatically, in some cases by over 100 points. They signal to lenders that you may be a high-risk borrower. Even if you manage to pay off the debt, the record of the event can linger on your credit report for years, continuing to affect your score.
How Long These Items Remain on Your Report
- Collections: Up to 7 years from the original delinquency date
- Bankruptcies: 7 to 10 years, depending on the type of bankruptcy
- Foreclosures: Up to 7 years
- Tax liens and judgments: Varies, but often several years
Steps You Can Take to Recover and Rebuild After Major Setbacks
- Start making on-time payments on all current accounts
- Pay down existing debt
- Work with creditors to resolve collections
- Regularly monitor your credit report for updates
- Rebuild your credit slowly with secured credit cards or credit-builder loans
