📊 The Truth About Credit Scores: What Really Affects Your Number (And What Doesn’t)

Your credit score isn’t just a number—it’s a key that unlocks access to loans, housing, insurance, and more. But do you truly understand what shapes it? Let’s dive into the facts, backed by reliable sources, so you can navigate your financial journey with clarity and confidence.

🧠 What Is a Credit Score?

A credit score is a prediction—a numerical estimate of how likely you are to repay borrowed money—based on your financial history as compiled by the credit bureaus cardratings.com+2consumerfinance.gov+2nerdwallet.com+2.

Two major scoring models dominate the U.S. market:

• FICO: Widely used by about 90% of lenders and ranges from 300–850, including industry-specific versions for auto loans, mortgages, and credit cards creditkarma.com+3files.consumerfinance.gov+3investopedia.com+3.

• VantageScore: Created by Equifax, Experian, and TransUnion, now on the same 300–850 scale and gaining popularity—especially VantageScore 3.0 and 4.0 banks.com+9files.consumerfinance.gov+9time.com+9.

Expect varied scores—depending on which bureau, which model, and when you check vantagescore.com+15files.consumerfinance.gov+15files.consumerfinance.gov+15.

🔍 The Top Credit Score Factors

Both models consider similar elements, with small differences in weight:

1. Payment History

   • Leading factor: 35% in FICO investopedia.comconsumerfinance.gov+15banks.com+15creditbrite.com+15; also heavily weighted in VantageScore files.consumerfinance.gov+15vantagescore.com+15experian.com+15.

   • Includes on-time payments, missed payments, collections, bankruptcies, etc.

2. Amounts Owed / Credit Utilization

   • Approx. 30% of FICO; highly important for VantageScore en.wikipedia.org+13banks.com+13vantagescore.com+13.

   • Aim to keep balances low—ideally under 30% of your credit limits.

3. Length of Credit History

   • About 15% in FICO; VantageScore views this as influential but variable creditcards.com+1kiplinger.com+1marketwatch.com+1creditcards.com+1.

4. Credit Mix

   • Revolving and installment accounts such as credit cards, mortgages, auto loans marketwatch.com.

5. New Credit / Inquiries

   • Hard inquiries can slightly lower your score; new accounts also count in both models investopedia.comen.wikipedia.org+5creditbrite.com+5time.com+5.

🧐 Minor Factors & Differences

• Medical debt has been deprioritized—some medical collections under $500 no longer impact scores, and bureaus now remove many from reports altogether consumerfinance.gov.

• Recent activity matters: both models look at new accounts and recent inquiries creditcards.com+2creditbrite.com+2time.com+2.

• Trended data (especially VantageScore 4.0 and FICO 10T) incorporate longer-term usage trends, not just a snapshot files.consumerfinance.gov+15fico.com+15time.com+15.

• Different models use different scoring criteria, meaning a “700” FICO is not the same risk profile as a “700” VantageScore fico.com+1investopedia.com+1.

✅ What Doesn’t Affect Your Credit Score

• Checking your own credit score (soft inquiry).

• Your income, salary, race, marital status, or occupation.

• Electric/gas service—unless it's sent to collection and reported.

💡 Why It All Matters

1. Access to Credit: A FICO score above 700 or VantageScore above 700 is typically seen as “good” creditcards.comfiles.consumerfinance.gov+5kiplinger.com+5files.consumerfinance.gov+5consumerfinance.gov.
