Credit & Debt Guide: Credit Scores, Loans & Debt Management
8 min read • Updated 2026
Your credit score affects everything from mortgage rates to car finance. This guide explains how credit works, how to check your score, and how to manage debt effectively.
What Is a Credit Score?
Your credit score is a number that lenders use to decide whether to lend you money and at what interest rate. The higher your score, the better your chances of getting approved and getting a lower interest rate.
- Excellent (961-999): Best rates available
- Good (881-960): Most lenders will approve you
- Fair (721-880): May get approved but rates may be higher
- Poor (561-720): Limited options, higher rates
- Very Poor (0-560): Likely to be declined

How to Improve Your Credit Score
Improving your credit score takes time, but these steps work:
- Pay bills on time: Late payments can stay on your report for 6 years
- Keep credit utilisation low: Use less than 30% of your available credit
- Check for errors: Mistakes on your report can drag your score down
- Don't apply for too much credit: Each application leaves a "hard search" that temporarily lowers your score
- Stay registered on the electoral roll: This proves your identity and boosts your score
⚠️ Avoid these credit killers: Missing payments, maxing out credit cards, applying for multiple credit cards in a short period, and having no credit history at all.
Understanding APR (Annual Percentage Rate)
APR is the total cost of borrowing, including interest and fees, expressed as a yearly percentage. It's the number to compare when shopping for loans and credit cards.
- Representative APR: At least 51% of successful applicants must get this rate or better
- Personal APR: The rate you actually get, based on your credit score
- 0% APR offers: Interest-free periods for balance transfers or purchases (but watch for fees)
📌 Always compare APRs, not monthly payments. A lower monthly payment might mean a longer loan term and more interest overall.
Types of Debt: Good vs Bad
Not all debt is equal:
- Good debt: Mortgages, student loans, business loans — investments that can build wealth
- Bad debt: Credit card debt, payday loans, high-interest personal loans — expensive and not building value
- Neutral debt: Car finance, 0% store cards — okay if managed carefully
Debt Repayment Strategies
- Snowball method: Pay off smallest debts first for quick wins and motivation
- Avalanche method: Pay off highest-interest debt first to save the most money
- Consolidation: Combine multiple debts into one loan with a lower interest rate
