What is credit?

Updated 12 Mar 2026Content was accurate at the time of publication

Credit is the ability to borrow money or access goods and services now with a promise to repay later. In plain terms: you receive value today and agree to pay for it over time, typically with interest and fees. Understanding credit — how it works, the types available, and how lenders assess you — helps you make better borrowing decisions, avoid costly mistakes, and protect your credit score and financial reputation.

How credit works

Credit is a legal and financial contract between a lender and a borrower. The lender provides funds or a payment facility and the borrower repays according to agreed terms.

Key components:

Principal: the amount borrowed.
Repayments: scheduled payments that usually include principal plus interest.
Interest: the cost of borrowing, shown as a rate (often expressed as APR or effective annual rate).
Fees: establishment fees, late fees, annual fees, and early repayment penalties.

Lenders set a credit limit or loan amount based on your financial profile. Revolving credit (e.g., credit cards) lets you borrow repeatedly up to a limit as you repay. Instalment credit (e.g., personal loans, mortgages) provides a lump sum repaid in fixed instalments over a set term.

Lenders assess serviceability — whether your income minus living expenses and other debts comfortably covers repayments. If you fail to meet repayments, lenders can charge fees, increase interest, list defaults on your credit report and, in extreme cases, take enforcement action.

Common types of credit

Knowing the main credit categories helps you choose the right product for your needs.

Secured vs unsecured

Secured credit is backed by collateral (for example, a home or car). Default can lead to repossession. Example: mortgage.
Unsecured credit has no collateral and relies on income and credit history. Example: most personal loans and credit cards.

Revolving vs instalment

Revolving credit lets you borrow, repay and borrow again up to a limit (credit cards, some lines of credit). Interest accrues on outstanding balances.
Instalment credit provides a lump sum repaid in fixed instalments over a set term (personal loans, car loans).

Common product examples

Mortgages: long-term, secured loans for property.
Personal loans: instalment loans for one-off expenses (home improvement, medical bills).
Credit cards: revolving unsecured credit for purchases and cash advances.
Overdrafts: short-term revolving facility attached to a transaction account.
Buy-now-pay-later (BNPL): short-term instalment credit for retail purchases; may be interest-free if paid on time but late fees can apply.
Trade credit: suppliers allowing businesses to delay payment.

How lenders assess creditworthiness

Lenders use multiple factors to decide whether to lend and on what terms:

Income: payslips, tax returns or other proof of regular income.
Living expenses: ongoing household costs used to calculate discretionary capacity.
Existing debt: other loans, cards, BNPL agreements and repayment obligations.
Credit history: past repayments, defaults, bankruptcies and the pattern of borrowing.
Collateral: for secured lending, the asset's value and condition.
Purpose of the loan: some lenders treat business or investment loans differently.
Serviceability test: lenders typically run affordability models, often stress-testing repayments under higher interest rates or reduced income.

Enquiries are recorded as soft or hard:

Soft enquiries (e.g., pre-approval checks) do not affect your credit record.
Hard enquiries (e.g., formal loan application) appear on credit reports and can slightly affect your score for a period.

Credit, credit reports and credit scores — the connection

Your credit behaviour is recorded by credit reporting bodies and summarised as a credit score. A typical credit report includes:

Personal identification details.
Open credit accounts and their status.
Repayment history and any missed payments.
Defaults, court judgments, bankruptcies and debt agreements.
Hard enquiries from lenders.
Public record information relevant to creditworthiness.

Consistent on-time repayments improve your score; missed payments, defaults and frequent hard enquiries reduce it. Lenders use both reports and scores to set interest rates and lending limits; a stronger score can mean lower rates and easier approvals.

Consumer protections and obligations

Lending in Australia is regulated to protect borrowers and ensure fair dealing:

Credit providers operating under the National Consumer Credit Protection (NCCP) framework must meet responsible lending obligations, including reasonable inquiries about your financial situation and ensuring loans are not unsuitable.
Credit providers generally need an Australian Credit Licence (or must act as a representative of a licence holder).
ASIC publishes consumer guidance on credit and loans.
If you have a dispute, use the lender's internal complaints process and escalate unresolved matters to the Australian Financial Complaints Authority (AFCA).

You also have obligations: provide accurate information when applying, read contracts and disclosure statements carefully, and meet repayment responsibilities. Contracts must disclose key terms such as interest rates, fees, minimum repayments and early repayment conditions.

Risks, costs and consequences of credit misuse

Credit can be a powerful financial tool, but misuse carries real costs:

Arrears and late fees: missed payments can trigger fees and higher interest.
Compounding interest: unpaid balances grow as interest accrues on interest.
Defaults and judgments: persistent non-payment can lead to a default listing and legal action.
Repossession and enforcement: secured loans can result in repossession of collateral.
Debt collection: third-party collectors can add stress and extra fees.
Long-term credit damage: defaults and bankruptcies can remain on your record for years, making future borrowing harder and more expensive.

For example, carrying a $1,000 credit card balance at 20% p.a. and paying only the minimum can extend the repayment period and substantially increase the total cost. Small unpaid balances can spiral when fees and compounding interest are added.

How to borrow responsibly

A practical checklist to borrow with control:

Check your current credit report and score before applying.
Create a simple budget: list income, necessary living expenses, and current debts to assess capacity.
Compare products — interest rates, fees, repayment frequency and features. Read product disclosure statements.
Read the contract: know the APR, fees, minimum repayments and early repayment conditions.
Choose the right type of credit: instalment loans for planned large purchases; limit revolving credit for everyday spending.
Borrow only what you can comfortably repay, including a buffer for rate rises or reduced income.
Keep emergency savings to avoid relying on high-cost credit for unexpected expenses.
If you fall behind, contact your lender early to discuss hardship options.

Alternatives to taking on credit

If you're weighing options, consider ways to reduce reliance on credit:

Build an emergency fund through regular small savings.
Delay non-essential purchases until you've saved the required amount.
Seek family support or small interest-free loans for short-term needs.
Explore community or not-for-profit lenders who offer low-cost, small loans.
Use budgeting tools or financial counselling services to manage cash flow and debt.

Key takeaways

Credit lets you access funds or goods now with a promise to repay later. Knowing how credit works, the types available, how lenders assess you, and how credit activity affects your credit report helps you make informed choices. Use the responsible-borrowing checklist, check your report before applying, read contracts carefully, and seek help early if you struggle.

FAQ

Does checking my credit hurt my score?

Soft checks (pre-approval, personal checks) do not impact your score. Hard checks from lenders when you apply can appear on your report and may slightly affect your score for a period.

Can I get credit with bad credit?

You may still get credit, but options and rates may be more limited or expensive. Consider secured loans, credit-building products and steps to improve your score first.

What happens if I miss a repayment?

The lender will usually charge late fees, report missed payments to credit reporting bodies, and may pursue collection or enforcement action if arrears continue.

How long does a default stay on my credit file?

Defaults typically remain on a credit file for several years. The exact period depends on the type of default and regulatory rules.

Are BNPL services the same as credit cards?

BNPL is generally short-term instalment credit for specific purchases and may be interest-free if paid on time. Credit cards are revolving credit with ongoing interest on outstanding balances. Both can affect your credit report.

Should I use a credit card or a personal loan for a big purchase?

For planned larger purchases, an instalment loan often gives predictable repayments and a fixed term. Credit cards are convenient for short-term needs if you can pay the balance promptly to avoid interest.

How do I dispute an incorrect entry on my credit report?

Contact the credit reporting body and the lender to raise a dispute. If unresolved, escalate to AFCA and consult the OAIC for privacy-related issues.

What is an Australian Credit Licence and why does it matter?

Lenders must hold an Australian Credit Licence to provide consumer credit; this ensures they meet regulatory standards and responsible lending obligations.
