How Credit Scores Work — And How Cards Influence Them
Credit scores are calculated from a mix of payment history, utilization, age of accounts, new credit and overall credit mix. This page breaks down how each factor works and why responsible card use can help build (or rebuild) a score.
Visit the Credit Score hubWhat a Credit Score Actually Measures
A credit score isn't a measure of wealth or income. It’s a statistical prediction of how likely you are to repay borrowed money. Scores are built from the patterns in your past behaviour with credit products — mainly credit cards, loans, and other accounts.
The system varies between countries, but the building blocks are nearly always similar:
- On-time payments
- How much of your limit you use
- How long you’ve held accounts
- Recent hard inquiries
- Your mix of credit types
The Five Major Score Factors
1. Payment history — the strongest factor. Late or missed payments can have a long-lasting impact.
2. Utilization — how much of your credit limit you use. Many models prefer consistent low utilisation (e.g., under 30%).
3. Account age — older accounts help because they show stability.
4. New credit — too many recent applications create short-term score drops.
5. Credit mix — having different product types (card + installment loan) can help long-term.
How Credit Cards Influence Your Score
- Cards help establish long credit history.
- Low utilisation signals responsible behaviour.
- On-time card payments build the strongest positive signals.
- Multiple cards increase total limits → lowers utilization ratio.
- But too many applications in short time can temporarily reduce scores.
A card is often the easiest and fastest way to build or rebuild credit — if used responsibly.
