A credit card with nothing owing can still be relevant to a loan application because the limit remains available to use. Start by recording both figures for every card: the current balance and the approved limit. They answer different questions.
For residential mortgages, APRA's APG 223 guidance gives an example of assessing revolving debt at 3% per month of the total committed limit. This is an example in mortgage-lending guidance, not a universal rule for every home, car or personal loan. Ask the actual lender how it treats your facilities.
See the difference between limit and balance
Using APRA's example solely to illustrate the arithmetic:
- A $20,000 committed limit produces an assumed $600 monthly commitment at 3%.
- A $5,000 committed limit produces $150 on the same assumption.
- The difference is $450 a month, even if both cards currently have a zero balance.
That $450 is a change in this illustrative assessment input. It is not a promise of $450 lower actual expenses, a specified extra loan amount or approval. The rest of the lender's income, expense and policy assessment still matters.
Build a card-limit inventory
Our worksheet has one row for each card: issuer, account identifier you can recognise, limit, balance, regular fees, direct debits and whether the account is joint or individual. Keep the latest statement or app-generated account record behind it.
This also prevents a common comparison error: using a balance from one date and a limit from another. If you have recently requested a change, record the request date and the date the issuer confirms it took effect. A request is not confirmation.
Decide what access you still need
Review recurring payments and any planned expenses before asking for a lower limit or closing an account. A card can be unused for purchases yet still pay an annual insurance premium or subscription. Moving those arrangements and allowing transactions to settle is part of closing an account cleanly.
Where a consumer has a contractual credit-limit reduction entitlement, sections 133BFA to 133BFC of the National Credit Act provide online request and implementation requirements. The practical document you need for a later application is confirmation of the resulting limit, not just the submitted form.
Show the next lender what changed
Keep the issuer's confirmation and an updated statement or account record. Give the lender or broker the accurate current information and ask whether it needs any further verification. Do not assume an external credit report has already refreshed or that every lender will calculate the effect in the same way.
Our household expense guide covers the wider budget. This exercise isolates the available-limit question so you can discuss it clearly without repeatedly applying for loans to discover a lender's policy.
If you are comparing car loans or a personal loan, ask about the proposed lender's own commitment treatment. The mortgage example above helps explain the concept; it should not be copied into a car-loan approval prediction.
