Credit & Debt: How Credit Scores, Loans, and Borrowing Decisions Really Work

Credit and Debt Banner Image

Credit affects borrowing costs, financial flexibility, and long-term outcomes, yet many people only encounter the system when something goes wrong. Approval decisions, interest rates, repayment rules, and penalties are often determined by mechanics that are rarely explained clearly.

This guide explains how credit and debt work as a system – covering credit scores, loans, credit cards, mortgages, student debt, and repayment strategies – so readers can understand risks, trade-offs, and consequences before making decisions.

Credit Scores, Reports, and Approval Mechanics

Credit decisions are driven by data recorded on credit reports and interpreted through scoring models and lender-specific rules. While credit scores are often presented as a single number, approval outcomes depend on a broader set of factors including utilisation, repayment history, account age, and recent activity. Understanding how lenders evaluate creditworthiness helps explain why similar applicants may receive very different terms – or be declined entirely.
