Credit card limit calculator for Australia

Enter one applicant or cardholder to see the credit limit in Australia. It is the lowest of what card behaviour allows, what income carries after other debt payments, the lender’s own income cap and the Australian rule, and the calculator names the one that sets it.

Market and caps

The Australian rule is read from ASIC instrument 2018/753 under the National Consumer Credit Protection Act. It sets no cap on the limit, and a card or an increase is unsuitable when the person could not repay the full limit within 3 years. Check the current text before relying on it.

The interest rate changes the result only for the United Kingdom, Australia, France, Belgium and Mexico, and the repayment period only for the United Kingdom.

0 leaves this cap off.

The limit is A$26,000, set by rules in Australia (ASIC). Behaviour gives A$30,000, income carries A$33,333, and the market’s rules allow A$26,908, which reflects an income cap in some markets and a repayment test in others.

High utilisation with enough statements paid in full earns the large increase.

Show formulas
Behaviour limit, New applicant = Starting income multiple × Monthly net income
Behaviour limit, Cardholder = Today’s limit × (1 + Large increase | Small increase) or × (1 − Cut after missed payments)
Affordability limit = (Income share for all debt payments × Monthly net income − Other debt payments) ÷ Card payment share of limit
Own income cap = Own income cap × Monthly net income
Market = Lowest applicable market cap
Credit limit = min(Behaviour limit, Affordability limit, Own income cap, Market), Rounded down Rounding step

The affordability limit assumes the card is fully drawn, and the behaviour rules are an example policy to edit, not a standard. Regulatory caps are summaries for this tool and are not legal advice.

How Australia sets card limits

ASIC sets no cap on a credit card limit in Australia. A card or a limit increase is unsuitable if the person could not repay the full limit within three years. The calculator estimates the limit repayable in equal monthly instalments over 36 months at the card’s rate, using income left after other debt payments.

The decision table shows the candidates, and the lowest sets the limit. Which one binds changes by person, so you can use the result to review an applicant or cardholder and edit the example behaviour policy.
