What a Credit Score Is — and Is Not
A credit score is a three-digit number (300–850) generated by a mathematical model to predict the statistical likelihood that you will be more than 90 days late on a payment within the next 24 months.
Critically, the Money Smarts books emphasize: a credit score is not a measure of your character, intelligence, income, bank account balance, or net worth. It is a single, narrow prediction — nothing more.
Credit Score Ranges
Qualifies for the best rates available on every product.
Qualifies for most credit products at strong, competitive rates.
Most lenders will approve you with competitive rates.
You can get credit, but expect higher rates and stricter terms.
Most traditional lenders will decline your application.
The Five Factors of Your FICO Score
FICO is used in over 90% of lending decisions. Your score is calculated from five weighted factors — understanding each one is how you take control of your credit.
The single largest factor. On-time payments build it; late payments, defaults, and collections damage it most severely.
Tip: Set autopay for at least the minimum on every account.
How much of your available credit you are using. Standard advice says stay below 30% — but the books stress below 10% is the true target for an excellent score. Maxing out cards severely damages this.
Tip: Pay balances down before your statement closing date, not just the due date.
Older, established accounts strengthen your score. Closing old credit cards hurts you twice — it reduces your average account age and increases your overall utilization ratio.
Tip: Never close your oldest credit card, even if you rarely use it.
A diverse mix of credit types strengthens your file — revolving credit (credit cards) plus installment loans (auto loans, personal loans, or mortgages).
Tip: Don't open new accounts just for mix — let it develop naturally over time.
Applying for too much credit at once creates multiple hard inquiries, each of which can slightly lower your score for up to 12 months.
Tip: Space out new credit applications by at least 6 months when possible.
Hard vs. Soft Inquiries
Occurs when a lender pulls your credit to make a lending decision. Stays on your report for two years and can slightly lower your score for up to 12 months.
Examples: Credit card application, auto loan, mortgage, personal loan.
Occurs when you check your own credit, an employer runs a background check, or a lender pre-approves you. Does not affect your score at all.
Examples: Checking your own score, employer background check, pre-approval offers.
There Is No Single Credit Score
The Money Smarts books emphasize that lenders use different scoring models for different purposes. You have dozens of scores — they vary by model, version, and what the lender is evaluating.
Used in over 90% of lending decisions. FICO Score 8 is the most widely used version for credit cards and auto loans. Older versions — FICO 2, 4, and 5 — remain the standard for mortgage underwriting.
Note: Requires at least 6 months of credit history to generate a score.
FICO's main competitor. VantageScore 4.0 can generate a score with as little as one month of credit history, making it useful for people just starting out.
Note: Can score with as little as 1 month of history.
Newer models incorporate non-traditional data — rent payments, utility bills, and bank account cash flow — to help score individuals with thin or limited traditional credit files.
Note: Designed for credit-invisible and thin-file consumers.
