Factor Breakdown
What a credit score is built from
Weightings below follow the widely published FICO model. Other models and other countries differ in detail, and the ordering is broadly consistent.
| Factor | Weight | What it measures | How fast it moves |
|---|---|---|---|
| Payment history | ~35% | Whether you have paid on time | Slowly — a late payment can stay for 6–7 years |
| Amounts owed / utilisation | ~30% | Balances relative to limits | Fast — updates with each statement |
| Length of credit history | ~15% | Average and oldest account age | Only with time; closing an old account hurts |
| Credit mix | ~10% | Variety of account types | Slowly, and not worth engineering |
| New credit | ~10% | Recent applications and hard searches | Recovers over 6–12 months |
Utilisation is the fastest lever available: it is nearly a third of the score and recalculates every month. Paying a card down before the statement date — not the due date — is the single most effective short-term action.
Widely believed things that are not true
- "Checking your score lowers it" —Checking your own score is a soft search and has no effect. Only a hard search from a credit application counts, and one has a small, temporary impact.
- "Carrying a balance builds credit" —It does not. Paying in full each month reports the same on-time payment and costs no interest. This myth is expensive at typical card rates.
- "Closing unused cards helps" —It usually hurts twice — it reduces total available credit, raising utilisation, and it eventually shortens average account age.
- "There is one credit score" —There are many, from different bureaux and models, and lenders often use their own. The score you see is indicative, not the one you will be assessed on.
- "Income affects your score" —It does not appear in the score at all. Lenders consider it separately when deciding affordability.
- "Debit card use builds credit" —It is not credit and is not reported. Neither, in most markets, is rent unless you use a specific reporting service.
About
The Credit Score Estimator calculates an estimated score range (300–850) based on the five factors used in FICO scoring: Payment History (35%), Credit Utilisation (30%), Length of Credit History (15%), Credit Mix (10%), and New Credit (10%). This is an educational tool — actual scores depend on your full credit report and the specific model used by a lender.

- What is the most important factor in a FICO credit score?
- Payment history is the single most important factor, accounting for 35% of your FICO score. Even one missed payment can significantly lower your score, and the impact is greater the more recent the missed payment. Consistently paying all bills on time — even the minimum payment — is the most effective thing you can do to build or maintain a good score.
- What credit utilisation ratio should I aim for?
- Financial experts generally recommend keeping your overall credit utilisation below 30% — ideally below 10% for the best scores. Utilisation is calculated as your total credit card balances divided by your total credit limits. For example, if you have a $10,000 limit and a $2,500 balance, your utilisation is 25%. Paying down balances or requesting a credit limit increase both reduce utilisation.
- Does checking my own credit score hurt my credit?
- No. Checking your own credit score is a soft inquiry and has no impact on your score. Only hard inquiries — initiated by lenders when you apply for credit — can temporarily lower your score by a few points. Multiple hard inquiries for the same type of loan (mortgage, auto) within a short window (14–45 days) are typically counted as a single inquiry by credit scoring models.
