What Is a Credit Score?

A credit score is a three-digit number ranging from 300 to 850 that reflects your creditworthiness. The higher the number, the better.

670-739Good
580-669Fair
300-579Poor

What Makes Up a Credit Score?

The most common model is the FICO Score. It considers 5 factors:

  1. Payment History (35%) — the most important factor. Pay on time!
  2. Credit Utilization (30%) — how much credit you use vs. your available limit
  3. Length of Credit History (15%) — longer is better
  4. New Inquiries (10%) — too many credit applications lower your score
  5. Credit Mix (10%) — a mix of cards, loans, and mortgages

Why Does a Good Credit Score Matter?

Your credit score affects nearly everything:

  • Renting — landlords check credit
  • Credit Cards — best cards require high scores
  • Auto Loans — lower interest rates
  • Mortgages — significant savings on interest
  • Insurance — some insurers factor in credit scores
  • Employment — some employers check credit history

How to Start Building Credit History?

For immigrants without US credit history, there are several paths:

  1. Get a secured credit card (with a deposit)
  2. Use a credit builder loan
  3. Become an authorized user on someone else's card
  4. Use Experian Boost to count utility payments

The key is to start as early as possible and always pay on time.
