Credit cards, when used strategically, are the fastest legal way to build exceptional credit. This chapter reveals exactly how credit scoring works and provides proven strategies to increase your score by 100+ points using credit cards as your primary tool.
How Credit Scoring Actually Works: The Truth Banks Don't Advertise
Credit scores aren't mysterious—they're mathematical formulas with known inputs. Understanding these formulas lets you game the system legally.
The FICO Score Breakdown
Your FICO score (used in 90% of lending decisions) consists of:1. Payment History (35%): Your track record of paying on time 2. Credit Utilization (30%): How much credit you use vs. available 3. Length of Credit History (15%): Age of accounts 4. Credit Mix (10%): Variety of credit types 5. New Credit (10%): Recent inquiries and accounts
The Hidden Scoring Factors
What FICO doesn't advertise: - Individual card utilization matters more than overall - $0 balances can hurt scores (shows inactivity) - Authorized user accounts count (with caveats) - Closed accounts continue aging for 10 years - Some actions have delayed impact (30-60 days)Score Ranges and Their Real Impact
- 300-579 (Poor): Subprime only, 25%+ APRs - 580-669 (Fair): Limited options, high rates - 670-739 (Good): Standard rates, most approvals - 740-799 (Very Good): Best rates, premium cards - 800-850 (Exceptional): VIP treatment, lowest ratesReal cost difference example (30-year mortgage): - 620 score: 7.5% rate = $419,000 total payments - 760 score: 5.5% rate = $325,000 total payments - Difference: $94,000
The Multiple Score Reality
You don't have one credit score—you have dozens: - FICO 8 (most common) - FICO 9 (newer, less adopted) - VantageScore 3.0/4.0 - Industry-specific scores (auto, mortgage, bankcard) - Each bureau's version (Equifax, Experian, TransUnion)Scores can vary 50+ points between versions.
