Understanding How Your Credit Score Is Calculated
Know the five FICO factors, how VantageScore differs, what hurts your score—and what you can do to improve it.
Your credit score is more than just a number—it’s your financial reputation. Lenders, landlords, and even employers may use it to determine your reliability. Knowing how your score is calculated helps you take control and make better financial choices.
The Five Key Factors in FICO® Scoring
FICO, the most widely used model, scores between 300 and 850 and weighs five main categories:

Payment History – 35%
Whether you pay bills on time. Even one late payment can cause a noticeable drop.

Amounts Owed – 30%
How much credit you’re using versus your total available credit (utilization).

Length of Credit History – 15%
Older accounts improve your score by showing long-term reliability.

New Credit – 10%
Too many new accounts in a short time looks risky to lenders.

Credit Mix – 10%
A variety of accounts—credit cards, loans, mortgage—shows financial responsibility.
How VantageScore Differs
While similar to FICO, VantageScore considers six factors, adding available credit as its own category. Payment history, utilization, and credit age remain the heaviest weights.
Negative Factors That Lower Your Score
- Late or Missed Payments – Stay on reports up to 7 years.
- Collections & Charge-offs – Strong negative marks, lasting 7 years.
- Bankruptcy – Chapter 7 remains for 10 years, Chapter 13 for 7.
- Maxed Out Cards – Raises utilization and drops your score.
- Closing Old Accounts – Shortens history and reduces total credit.
- Multiple New Applications – Each inquiry can reduce points.
- Foreclosure & Defaults – Remain on your record for years and limit future approvals.
How to Improve Your Score
Rebuilding takes consistency, but small steps add up. Start here:
- Check your Annual Credit Report – Look for errors or fraud.
- Dispute inaccuracies – Removing false negatives can lift your score.
- Seek professional help – Credit repair services can create tailored plans.
- Pay off collections – Prevents further reporting and improves history.
- Explore hardship programs – Many lenders offer temporary relief.
