What Is a Credit Score?
A credit score is a three-digit number that represents your creditworthiness—essentially, how likely you are to repay borrowed money. Lenders, landlords, insurance companies, and even some employers use credit scores to assess financial risk.
The most commonly used credit score is the FICO® Score, which ranges from 300 to 850. VantageScore is another popular model with a similar range. While the exact algorithms are proprietary, both models consider similar factors when calculating your score.
Credit Score Ranges Explained
According to Experian, the average FICO® Score in the United States is around 716 (as of 2024). Achieving a score above 740 puts you in the "Very Good" category, qualifying you for better interest rates and loan terms.
The Five Factors That Determine Your Credit Score
1. Payment History (35%)
Your payment history is the single most important factor affecting your credit score. It tracks whether you've paid your bills on time, including credit cards, loans, and other accounts.
Impact:
- Even one late payment (30+ days) can significantly hurt your score
- The more recent the late payment, the bigger the impact
- Bankruptcies, foreclosures, and collections have severe effects
- Positive payment history builds over time with consistent on-time payments
What to do: Set up automatic payments for at least the minimum amount due. Use calendar reminders if you prefer manual payments. Even if money is tight, prioritize making at least the minimum payment on time.
2. Credit Utilization (30%)
Credit utilization is the ratio of your current credit card balances to your credit limits. It's calculated both per card and across all your cards combined.
Calculation: If you have a $10,000 total credit limit and owe $3,000, your utilization is 30%.
Optimal ranges:
- Below 30%: Generally acceptable
- Below 10%: Ideal for excellent scores
- Above 50%: Significantly hurts your score
- 0%: Not necessarily best—shows you're using credit
What to do: Pay down balances, request credit limit increases (without increasing spending), or make multiple payments throughout the month to keep reported balances low.
3. Length of Credit History (15%)
This factor considers the age of your oldest account, the age of your newest account, and the average age of all your accounts. Longer credit history is generally better.
What affects it:
- Opening new accounts lowers your average account age
- Closing old accounts can reduce your credit history length
- Being an authorized user on an old account can help
What to do: Keep old credit cards open and active (use them occasionally for small purchases). Think carefully before closing your oldest account. Be strategic about opening new accounts.
4. Credit Mix (10%)
Having different types of credit accounts—such as credit cards, installment loans (auto, student, mortgage), and retail accounts—can positively affect your score.
Types of credit:
- Revolving credit: Credit cards, lines of credit
- Installment loans: Auto loans, mortgages, student loans
- Open accounts: Utility bills, cell phone contracts (sometimes reported)
What to do: Don't open accounts just to improve your mix. Let it develop naturally as you take out loans for homes, cars, or education. Focus on the higher-impact factors first.
5. New Credit Inquiries (10%)
When you apply for new credit, lenders perform a "hard inquiry" on your credit report. Too many hard inquiries in a short period can lower your score.
Types of inquiries:
- Hard inquiries: Credit applications (cards, loans, mortgages)
- Soft inquiries: Checking your own credit, pre-approval offers, employment checks
- Rate shopping: Multiple inquiries for the same loan type within 14-45 days count as one
What to do: Only apply for credit when necessary. When rate shopping for auto or mortgage loans, do it within a short time frame. Check your own credit regularly (soft inquiry) to monitor progress.
How to Build Credit from Scratch
If you're new to credit or have limited credit history, here's how to start building a positive credit profile:
Step 1: Get a Secured Credit Card
Secured cards require a cash deposit (typically $200-$500) that becomes your credit limit. Use it responsibly, pay on time, and many issuers will upgrade you to an unsecured card after 6-12 months.
Step 2: Become an Authorized User
Ask a family member with good credit to add you as an authorized user on their card. You'll benefit from their positive payment history and credit age. Ensure they have low utilization and on-time payments.
Step 3: Consider a Credit Builder Loan
These small loans (typically $300-$1,000) are held in a savings account while you make payments. After paying off the loan, you receive the money. It's a low-risk way to build payment history.
Step 4: Report Rent and Utility Payments
Services like Experian Boost, RentTrack, and Rental Kharma allow you to add rent, utilities, and phone bills to your credit report. This can help if you have thin credit files.
Step 5: Use Credit Responsibly
Once you have credit, use it regularly for small purchases and pay the full balance each month. This demonstrates responsible credit management without paying interest.
How to Improve a Low Credit Score
If your credit score has taken a hit, here are actionable strategies to rebuild it:
Quick Wins (30-90 days)
- Pay down credit card balances: Reducing utilization can improve scores quickly
- Dispute errors: Check reports for inaccuracies and dispute them
- Become an authorized user: Immediate boost from someone else's good credit
- Request higher credit limits: Lowers utilization if you don't increase spending
Medium-Term Strategies (3-12 months)
- Establish perfect payment history: Not a single late payment for at least 6 months
- Pay more than minimums: Reduces balances faster and shows financial responsibility
- Negotiate with creditors: Ask for goodwill deletions of late payments or negotiate pay-for-delete agreements
- Diversify credit types: Add an installment loan if you only have cards (or vice versa)
Long-Term Rebuilding (1-7 years)
- Wait out negative items: Late payments (7 years), bankruptcies (7-10 years) eventually fall off
- Build positive history: The longer you maintain good habits, the more your score improves
- Monitor progress: Check credit reports quarterly to track improvements
- Stay patient: Credit repair takes time, but consistent effort pays off
Common Credit Score Myths Debunked
Myth 1: Checking your credit hurts your score
Truth: Checking your own credit is a soft inquiry and does NOT affect your score. You should check your credit regularly.
Myth 2: Carrying a balance improves your score
Truth: Paying interest doesn't help your credit. Pay the full balance each month to avoid interest while building good payment history.
Myth 3: Closing cards improves your score
Truth: Closing cards reduces available credit (increasing utilization) and can shorten credit history. Keep old cards open unless there's an annual fee.
Myth 4: Income affects your credit score
Truth: Your income is not part of your credit score calculation. However, it may affect loan approval amounts.
Myth 5: You only have one credit score
Truth: You have many credit scores based on different models (FICO, VantageScore) and bureaus (Experian, Equifax, TransUnion). Scores can vary by 20-50 points.
