US Credit Score System Explained

Why your U.S. credit score matters, how it is calculated, and how to build it quickly as a new Indian immigrant.

Overview

The U.S. credit score — typically the FICO score, ranging from 300 to 850 — is a mathematical representation of your reliability in repaying debt. Without a good score, you will struggle to rent an apartment, get an auto loan, secure a mortgage, or even get a cell phone plan without a large security deposit.

For Indians Moving From India

Your Indian CIBIL score does not transfer to the United States. You will start with no credit history and be essentially invisible to the three U.S. credit bureaus — Experian, Equifax, and TransUnion. Building credit from zero is a deliberate process that takes at least six to twelve months.

For Indians Already in the US

Actively monitor your credit report to confirm on-time payments are being tracked correctly and to protect against identity theft. You are entitled to one free credit report per year from each bureau at AnnualCreditReport.com.

Key Information

Your FICO score is calculated based on five factors: Payment History (35%), Credit Utilization (30%), Length of Credit History (15%), Credit Mix (10%), and New Credit Inquiries (10%). A score above 750 is considered excellent.

Requirements

An SSN or ITIN for the bureaus to accurately track your credit history.

Common Mistakes

Missing a payment or making a late payment is the single most damaging mistake — it stays on your credit report for seven years. Maxing out your credit limit severely hurts your credit utilization ratio.

Practical Tips

Always keep credit utilization below 30% of your total limit. Set up autopay for the full statement balance every month to ensure you never miss a payment.
