Credit Cards: Use the Tool, Avoid the Trap

The non-negotiable rule

Pay the full statement balance before the due date, every month. Revolving credit at 30–45% annualised interest destroys any rewards you earn. If you cannot clear the bill, stop discretionary swipes immediately.

Rewards math without the hype

Compare effective value after excluding fees, capped categories, and reward blackout dates. A simple 1–2% flat cashback card can beat a complex points card if you value your time and hate fine print.

Healthy habits

Small operational habits prevent expensive mistakes:

• Enable due-date reminders and autopay for at least the full amount when cash flow is stable.
• Keep utilisation moderate; very high utilisation can pressure your credit score.
• Avoid cash advances — fees and interest typically start immediately.
• Track annual fees vs benefits; downgrade cards you do not use.
