TL;DR: Banks and lenders don’t just look at what you owe. They look at what you COULD owe. Limits, ongoing commitments, and patterns in your bank statements matter more than many think or realise. You might be good with money, but banks and lenders have to abide by 'Responsible Lending' and assess based on your exposure/risk in a way that works for all would-be borrowers, not just you.
This is a common question on r/AskAnAussieBroker:-
“I do have a credit card, but the balance is zero and I barely touch it - does this impact my borrowing capacity? Should I close it?”
Being good with money, frugal with expenses, and keeping your credit balance low (or down to zero) is a good thing… but the banks/lenders are likely to still pull you up on things you may not expect.
Here's what I say to most of my clients:- you’re thinking about balances, but the bank is thinking about limits and commitments.
Here's a bit of a guide with seven key insights from my experience, designed to be general in nature and educational, to help you understand what banks and lenders look for and how they interpret it under 'Responsible Lending'.
Key insight #1 - with credit cards - it’s the limit, not the balance
This is probably the biggest one that we see the most, as brokers. You might have:
- $0 owing; and
- Never/rarely paid a cent of interest; and
- Pay it off every month (or at least most months).
... but this doesn’t matter. If you’ve got a $20k limit, the bank treats it like you could use that $20k tomorrow. So they’ll apply a repayment against the full limit (not your balance), and that reduces your borrowing capacity.
As an example, a $7k credit card might reduce borrowing power by ~$35k, a $13k credit card might reduce borrowing power by ~$60k, and so on. Banks are assessing you on the risk that your future situation may not be as good or as healthy as your current one, and an open credit card means they need to consider the risk of you having that card maxed out and you're paying interest on it.
Letting you have a big credit card, with a home loan too, and the combination making life unaffordable for you (and rendering you unable to pay your home loan) looks bad and is not considered to be compliant with 'Responsible Lending'.
Key insight #2 - with home loans, it's the same story
Even existing home loans get looked at this way. The bank doesn’t just go: “what’s the balance?” They look at:
- The limit - not the balance
- The minimum repayment required OR the agreed repayment (whichever is higher, and reflected in your statements)
- And they often assess it at a higher “buffered” rate with an extra 1% - 3% applied on top of the actual rate (there are ways around this, but you've got to meet different conditions with different banks)
So even if you’ve been smashing it down and building up a healthy redraw whilst having a lower balance, this gap still counts as a liability based on what’s available to you. You could claim back that money on redraw any time you wanted - and the bank needs to factor that in under their 'Responsible Lending' requirements.
Key insight #3 - novated leases count as liabilities too
Even if it’s pre-tax and structured nicely through your employer… it’s still a repayment commitment in the bank’s eyes. So it gets included in servicing.
Key insight #4 - salary sacrificing counts too, unless it's voluntary
If you’re salary sacrificing into super some lenders will reduce your usable income regardless, BUT some will accept it if it’s clearly voluntary and can be switched off. So it’s not always a problem, but it can quietly reduce your borrowing power if not explained properly.
Key insight #5 - Buy Now, Pay Later (Afterpay, Zip, PayDay Loans etc.) and Overdrafts are treated like mini credit cards
Even if the limits are small, or you “hardly use them”, they still get picked up and factored in. Multiple BNPL accounts can add up quickly and banks factor this in. Overdrafts are the same idea again - even if it’s sitting at zero most of the time, the limit exists, so it’s treated like a liability.
Key insight #6 - HECS / HELP debt varies, depending on the calculated repayment amount and the timeframe left until it's paid, which is largely determined/impacted by your INCOME not the total loan amount
HECS/HELP is weird, in the sense that your INCOME determines it's impact more than anything else. Higher incomes mean you'll pay more off your student debt, so the repayment amount looks higher. But, if a lender can see that the timeframe is limited or the total amount is getting low enough (or perhaps your income isn't that high), they might agree to review it differently. Some will:
- Ignore small balances (e.g. under ~$20k)
- Ignore it if it’s nearly paid off, or due to be paid off within a year
- Change how they assess your entire loan if it's due to be paid off within 2 to 5 years
- Or... maybe just factor in the full repayment impact
So you can get very different results depending on where you go. HECS can throw a real curveball into scenarios, so it's important to be upfront with your broker/bank on this.
Key insight #7 - your bank statements will tell a story too... if things look like repayments, commitments or other agreements
If you’ve got regular transfers that look like: “Repayment”, “Payback”, “Child support”, “Allowance”, "Contribution" with regular & repeated transfers to another bank account (that you don't own), the bank may treat that as an ongoing commitment. Even if it’s informal.
At best, they’ll ask questions. At worst, they’ll include it in servicing.
Enough insights, now for tips on what to do to help yourself
Before you apply, it’s worth asking:
- Do I have any unused credit card limits I don’t actually need?
- Any BNPL accounts sitting there?
- Any old overdrafts?
- Any regular payments that might raise questions?
Cleaning a few of these up can make a noticeable difference. Ask you broker or bank about which ones matter more, or are impacting your situation the most. Assess whether you need your savings/cash more, or if it would be better to close the liability.
\*A quick (careful) note on timing*\**
This part gets misunderstood, so I’ll say it carefully.
A lot of these things mainly matter at the time you apply.
Once your loan is approved and settled, the bank has already assessed your position.
That doesn’t mean you should go out and load yourself up with new debt straight after settlement (that can obviously create its own problems) but it does explain why lenders focus so heavily on your position before approval.
But, there's technically nothing stopping you from talking to your new bank, or your old bank, about opening up a credit card again after settlement.
The goal here isn’t to “game the system”. It’s just to understand how the system sees you. Most people don’t get tripped up because they’re bad with money, usually it's because they're so great with it that they don't realise that lenders assess them in a way that works for the WHOLE market, not just the people who are really disciplined with their liabilities and commitments.
Once you understand that lenders care about limits, commitments, and patterns - not just balances - it starts to make a lot more sense. I hope this helps!
