Credit score factors: the core elements behind modern scoring models.
“Credit score” is an umbrella term for numerical models used by lenders to assess risk. While exact formulas vary between countries and bureaus, most models rely on similar structural components: **payment history, credit usage, length of credit history, new inquiries and the types of accounts you hold.**
This guide breaks those components down in clear, neutral language. It interfaces naturally with the Credit Score & Rebuild hub, the Student hub, and rebuild-related minisites like CreditBuilder.Creditcard and Secured.Creditcard.
The main components of credit scoring models
While different bureaus weigh factors differently, the following five pillars appear across most systems:
- Payment history – whether bills were paid on time.
- Credit utilization – used credit relative to available credit.
- Age of accounts – how long credit accounts have been open.
- Credit mix – variety of credit types (cards, instalment loans, etc.).
- New credit & inquiries – how often new applications occur.
These components influence eligibility for many cards in the Student hub, the Score & Rebuild hub, and across minisites such as CompareCC.Creditcard.
Payment history: consistency over time
Payment history is typically one of the most influential components in a credit scoring model. It reflects whether prior obligations were fulfilled on time, including credit cards, loans, utilities and other reportable bills.
- On-time payments are usually seen as indicators of reliability.
- Late payments may be recorded if past a certain grace period.
- Severity matters – missed payments on instalment loans may be treated differently from revolving credit.
- Duration matters – negative markers may reduce in impact over time depending on bureau rules.
Payment history interacts with the APR and borrowing behaviour topics explained in the APR basics guide.
Credit utilization: revolving balance vs. available credit
Utilization looks at the proportion of credit used compared with credit available. Models often view lower utilization as less risky than high utilization, regardless of your income or total savings.
- Most systems calculate utilization on **individual cards** and in **aggregate**.
- Changes in utilization can occur quickly as balances update.
- Carrying high revolving balances may signal higher risk in scoring models.
- Large swings can sometimes be interpreted differently from stable trends.
This factor is also relevant when comparing reward structures in the points vs cashback guide, as spending patterns relate to utilization in many scoring systems.
Age of credit: how long accounts have been open
Scoring models often consider the average and total age of open accounts. Longer credit histories may be interpreted as giving models more data to evaluate.
- Average age – typical metric combining all active accounts.
- Oldest account – models may use the age of the oldest credit line as a stability indicator.
- New accounts – opening several new accounts within a short period may affect averages.
- Closed accounts – treatment varies: some bureaus include closed accounts for a number of years.
This is why student and first cards in the Student hub are often positioned as establishing early credit history in many countries.
Credit mix: revolving vs. instalment accounts
Some scoring models consider the types of credit products held, often looking for a combination of revolving accounts (credit cards) and instalment accounts (such as car loans or student loans).
- Having only one type of credit product may provide less information for models.
- Installment accounts behave differently because balances decline in predictable schedules.
- Revolving accounts allow more variation, which models treat differently.
- Not all countries or bureaus use credit mix in the same way.
These concepts appear frequently in rebuild-oriented hubs such as Score & Rebuild and minisites like CreditBuilder.Creditcard.
New credit & inquiries: applications and timing
Scoring models often look at how frequently new credit is requested. Multiple applications in a short period may be interpreted differently from occasional inquiries, depending on the context and type of credit sought.
- Hard inquiries – typically logged when applying for credit.
- Soft inquiries – usually not used in scoring.
- Clustering – many inquiries within a small time window may carry more weight.
- Context – inquiries for the same loan type may be treated differently in some systems.
New credit behaviour also ties into topics explained in the secured & builder cards guide.
