Credit Scores Explained

Your credit score is a three-digit number that represents your creditworthiness. Learn how scores are calculated, the differences between scoring models, and what you can do to improve yours.

What is a Credit Score?

A credit score is a numerical representation of your credit risk based on the information in your credit report. Lenders use it to quickly assess how likely you are to repay a loan.

While there are many scoring models, the two most dominant are FICO® (Fair Isaac Corporation) and VantageScore®.

FICO vs. VantageScore

Although both models use a 300-850 range and consider similar factors, they weigh them differently.

300-579PoorRejected for most unsecured credit

Scoring Factors (FICO)

Understanding what makes up your score is the key to improving it.

Payment History

35% Impact

Lenders want to know if you pay back what you borrow.

  • Late payments (30+ days) hurt significantly
  • Collections & bankruptcies are severe
  • Recency matters—older lates hurt less

Amounts Owed

30% Impact

Credit utilization: how much of your limit you're using.

  • Aim for <30% utilization
  • <10% is ideal for top scores
  • High balances on single cards still hurt

Length of History

15% Impact

Average age of accounts and age of oldest account.

  • Don't close old cards
  • New accounts lower average age
  • History builds slowly over time

Credit Mix

10% Impact

New Credit

10% Impact

Mix of account types and recent inquiries.

  • Revolving (cards) + Installment (loans) is good
  • Hard inquiries stay for 2 years
  • Opening many accounts at once is risky

Improving Your Score

Strategies to boost your score efficiently:

1

Fix Errors

Dispute inaccurate late payments or collections. Removing a single error can raise your score 50-100 points.

2

Pay Down High Balances

Pay cards down to below 30% of their limit. Do this before the statement closing date.

3

Request Higher Limits

Ask issuers for a credit limit increase (without a hard inquiry) to instantly lower utilization.

4

Become an Authorized User

Ask a family member with good credit to add you to their card. Their history gets added to your report.

Why Do I Have Different Scores?

It's completely normal to have different scores. Here's why:

  • Different bureaus — Each bureau may have different information
  • Different scoring models — FICO vs VantageScore, different versions
  • Different dates — Scores change as your report is updated
  • Industry-specific scores — Auto and mortgage lenders use specialized scores

What matters is the overall trend—are your scores generally improving over time?
