Short answer: yes, credit card debt can affect a car loan application. But what surprises most people is that lenders usually care about your credit card limit as much as your balance. A card with a $0 balance can still reduce how much you can borrow.
This guide explains how that works in Australia, what lenders look for on your credit file, and what you can do before you apply.
1. Lenders count your limit, not just what you owe
When a lender works out whether you can afford a car loan (called a serviceability assessment), it lists all your existing commitments. For credit cards, most lenders don't use your actual balance or minimum repayment. They assume you could draw the card to its full limit at any time and apply a notional monthly repayment, typically somewhere around 3% to 3.8% of the limit, depending on the lender.
Example: say you have two cards with a combined limit of $15,000. Even if both are paid off, a lender might count roughly $450 to $570 a month as a commitment. That's about the same as the repayment on a modest car loan, and it can be the difference between approval and a decline, or between the car you want and a cheaper one.
2. Your balance and repayment history still matter
Limits drive the affordability maths, but your balances and behaviour show up elsewhere:
- Repayment history. Under comprehensive credit reporting, your credit file can show whether you've paid on time each month over the past two years. Late payments on a card are a bigger red flag than a high balance.
- Bank statements. Lenders usually review recent statements. Cards that are constantly maxed, cash advances, or only ever paying the minimum can suggest you're stretched.
- Recent applications. Applying for several cards or loans in a short period leaves enquiries on your file, and lenders may ask why.
3. What you can do before applying
- Reduce or close limits you don't need. This is often the single most effective step. If you close a card, keep the closure confirmation, because your credit file can take time to update and a lender may ask for proof.
- Pay down balances where you can. It won't change the limit-based calculation, but it improves how your statements and credit file look.
- Don't apply for new credit in the lead-up, including buy now pay later accounts, which lenders increasingly ask about.
- Get a free copy of your credit report from the credit reporting bodies (Equifax, Experian and illion) and check it for mistakes.
- Consider the size of the loan. A bigger deposit, a cheaper car or a longer term can bring the numbers back within a lender's limits.
4. What if I'm already behind on my cards?
If you've missed payments recently, mainstream lenders may decline, but some specialist lenders look at the reasons and how you've managed since. Expect higher interest rates and closer scrutiny. Sometimes the better move is to spend a few months getting repayments back on track before applying. If you're struggling, the free, confidential National Debt Helpline (1800 007 007) can help.
5. How a broker helps
Lenders treat credit cards differently: they use different percentages and view closed-but-not-yet-updated cards differently. A broker can look at your full picture before anything goes to a lender, tell you whether reducing a limit first is worth it, and point you to lenders whose policies fit, which helps you avoid collecting declined applications on your file.
