Understanding Your Credit Score: What It Is, How It’s Calculated, and Why It Matters

April 30, 2025 admin Credit Building, Credit Scores

Your credit score can determine whether you’re approved for an apartment, a car loan, a mortgage — even certain jobs. Yet many people don’t know how their score is calculated, what affects it, or how to improve it.

In this article, we’ll break down what a credit score actually is, what goes into it, and how to take control of your credit profile — whether you’re just getting started or working to repair your history.

What Is a Credit Score?

A credit score is a three-digit number, typically between 300 and 850, that reflects how likely you are to repay borrowed money. The higher your score, the more trustworthy you appear to lenders. Scores are based on your credit history and are calculated by models like FICO or VantageScore.

300–579PoorApproval will be difficult, higher risk.

What Affects Your Credit Score?

Credit scores are calculated based on five main factors. Knowing how each one works can help you build or maintain a strong score.

1. Payment History (35%)
This is the most important factor. Lenders want to know if you pay your bills on time. Late payments, charge-offs, or accounts in collections can seriously damage your score.

2. Credit Utilization (30%)
This is how much of your available credit you’re using. For example, if you have a $1,000 limit and carry a $500 balance, you’re using 50%. Try to keep this ratio under 30%, and ideally under 10%.

3. Length of Credit History (15%)
The longer you’ve had credit accounts open, the better. Lenders look at the average age of your accounts, so avoid closing your oldest cards unless necessary.

4. Credit Mix (10%)
Having different types of credit — like a credit card, a student loan, and a car loan — shows lenders you can manage various financial responsibilities.

5. New Credit / Inquiries (10%)
Every time you apply for credit, it creates a hard inquiry on your report. Too many inquiries in a short time can lower your score.

How to Improve Your Credit Score

Whether you’re just starting or trying to recover from past mistakes, here are some key steps:

  • Pay all your bills on time, every time.
  • Keep your credit card balances low.
  • Don’t apply for too many new accounts at once.
  • Avoid closing old accounts with good history.
  • Use a secured credit card if you’re building from scratch.
  • Review your credit reports regularly and dispute any errors.
