Credit Score in the USA — How to Build Credit History from Scratch

Introduction

Credit score (300-850) determines life in the USA — renting, car loans, credit cards, mortgages, insurance. Without a credit score, you are invisible to the financial system. Reaching 700+ in 6-12 months is achievable.

What is a Credit Score

• 300-579: Poor — everything is more expensive
• 580-669: Fair — cards with high APR
• 670-739: Good — most products
• 740-799: Very Good — best rates
• 800-850: Exceptional
• Goal: 700+ in 12 months

Three Credit Bureaus

• Experian, TransUnion, Equifax — collect data independently
• Score may vary between bureaus
• Landlords usually check one

FICO vs VantageScore

• FICO — used by 90% of lenders
• VantageScore — shown by Credit Karma
• FICO matters for important decisions (mortgage)

What Builds a Credit Score

• 35% Payment history — do you pay on time
• 30% Credit utilization — % of limit (goal: below 30%, ideally below 10%)
• 15% Length of history — average account age
• 10% Credit mix — diversity
• 10% New inquiries

Building Plan from Scratch

Step 1: SSN/ITIN + Bank Account

• Obtain an SSN (if eligible to work) or ITIN
• Open an account (PSFCU/Chase)
• A bank account alone does not build credit, but it is the foundation

Step 2: Secured Credit Card

• Card with a deposit (200-500 USD); limit = deposit
• Best options:
  • Discover it Secured — 0 USD fees, 2% cashback, conversion to unsecured after 7 months.
  • Capital One Platinum Secured — deposit 49-200 USD
  • PSFCU Secured Visa — for members
• Use for small purchases (Netflix, phone)
• Pay in full every month
• After 6-7 months — score 650-700+

Step 3: Petal / Capital One

• Petal 2 Card — uses Cash Score, no history required; limit 500-10k
• Capital One QuicksilverOne — "Fair" credit
• These cards report from day one

Step 4: Self Lender

• Credit builder loan — 25-150 USD/month for 12-24 months.
• Money held in a deposit; you get it back
• Builds an "installment loan" (diversity)

Step 5: Experian Boost

• Free: phone, electricity, internet, Netflix bills count towards history (through Experian)
• experian.com/boost
• Average +13 points instantly

Step 6: Authorized User

• Spouse/parent with an older card adds you as an AU
• The history of that card appears on your report

What Harms Your Score

• Late payment (30+ days) — -50 to -100 points; visible for 7 years
• High utilization (>30%) — temporary drop
• Closing the oldest card — shortens history
• Hard inquiries too frequently
• Collections — -100 to -150 points; 7 years
• Bankruptcy — -200 to -300 points; 7-10 years

What Does NOT Affect Your Score

• Income, savings in the account
• Employment status
• Age, race, nationality
• Rent (unless the landlord reports)

Checking Your Report

• annualcreditreport.com — free weekly from 3 bureaus
• Credit Karma — TransUnion + Equifax + alerts
• Credit Sesame
• Your bank/card — often shows FICO

Realistic Timeline

• Month 1: Secured + Self → score 580 (new history)
• Month 3: first reported → score 620
• Month 6: 6 months of history → score 680-700
• Month 12: "real" card (Chase, Amex) → score 720-740
• Month 24: auto loan, mortgage → score 750+

Common Mistakes

• Waiting to "build credit" — without an active card, nothing happens
• Paying the minimum — interest 20-30% APR
• Not using the card — it gets closed by the issuer
• High utilization in one month — keep below 10% on reporting day
• Closing the first secured — losing the oldest line
• Applying for many cards at once — hard inquiries
