Credit
Credit scores, credit cards, and borrowing explained.
Credit is a record of how you have borrowed and repaid money. Lenders summarize that record as a credit score — most commonly a FICO or VantageScore number between 300 and 850 — built from your payment history, how much of your available credit you use, the age of your accounts, your mix of credit types, and recent applications.
This section explains how those pieces fit together: how a score is calculated, what a credit report contains, how credit-card interest and grace periods work, and how borrowing costs are expressed as an APR. The goal is to make the system legible so the numbers on your statements stop being a mystery.
For borrowing decisions, the Credit Card Payoff and Debt-to-Income calculators turn these concepts into concrete figures for your own balances.
