How Much Can I Borrow for a Car Loan in Australia?
Learn how much you can borrow on a car loan in Australia — what lenders check, how much is too much, and how to use our free calculator.
Knowing how much you can borrow before you walk into a dealership is the difference between a car you can afford and one that owns you. Here's exactly what Australian lenders look at, how to calculate your borrowing power, and how to use our free car loan calculator.
What Lenders Actually Check
When you apply for a car loan, the lender runs a hard credit check and assesses several factors to determine both whether to approve you and how much to lend:
The big five:
- Income — your gross and net income from all sources. Lenders want to see stability (same employer for 6+ months minimum).
- Debt-to-income ratio (DTI) — total monthly debt repayments divided by gross monthly income. Most lenders cap this at 30%.
- Living expenses — estimated using the Household Expenditure Measure (HEM) or your actual declared expenses, whichever is higher.
- Credit score — your Equifax score. Higher = better rates. Lower = higher rates or rejection.
- Loan-to-value ratio (LVR) — the loan amount as a percentage of the car's value. Under 80% is ideal.
How to Calculate Your Borrowing Power
Here's a simple way to estimate your maximum car loan amount before you apply:
- Calculate your gross monthly income (before tax)
- Add up all existing monthly debt repayments (credit cards, personal loans, HECS, etc.)
- Multiply your gross monthly income by 0.30 (30% DTI cap)
- Subtract your existing monthly debt repayments from that figure
- The result is your maximum monthly car loan repayment capacity
If you earn $5,000/month gross and have $500 in existing debt repayments: $5,000 × 0.30 = $1,500. $1,500 − $500 = $1,000/month available for a car loan. At 8% over 5 years, $1,000/month lets you borrow approximately $49,000.
How Much Is Too Much?
Just because a lender will approve you for $50,000 doesn't mean you should borrow $50,000. Here's how to think about it:
| Loan Amount | Monthly Repayment (8%, 5yr) | Total Interest Paid | Comfortable? |
|---|---|---|---|
| $15,000 | $304 | $3,240 | Very comfortable |
| $25,000 | $507 | $5,420 | Comfortable for most |
| $35,000 | $710 | $7,600 | Tight on a single income |
| $50,000 | $1,014 | $10,840 | Stretching — reconsider |
| $70,000 | $1,420 | $15,200 | Danger zone for most buyers |
Never borrow to your absolute maximum. Life happens — job changes, rate rises, unexpected repairs. Leave yourself a 20% buffer between what you're approved for and what you actually borrow.
Using Our Free Car Loan Calculator
Our car loan calculator does the maths for you. Here's how to use it effectively:
- Enter the car price you're considering (or your pre-approval amount)
- Add your deposit or trade-in value
- Input the interest rate you've been quoted (or use 8% as a conservative estimate)
- Set the loan term — 3 to 5 years is ideal; anything over 7 years means you're borrowing too much
- Add any balloon payment if the lender has suggested one (read our balloon payment guide first)
The calculator will show you your monthly repayment, total interest paid, and total cost of the loan. Use these numbers to compare offers from different lenders.

Tips to Increase Your Borrowing Power
- Pay down existing debts before applying — lower DTI means more capacity
- Save a bigger deposit — lower LVR means better rates and more borrowing power
- Check and fix your credit report — dispute any errors at Equifax
- Avoid applying for multiple loans in a short period — each application is a hard enquiry
- Consider a co-borrower if your income is low — joint applications combine incomes
Don't Forget the Comparison Rate
The interest rate the lender advertises is not what you'll actually pay. Fees — establishment, monthly, early exit — all add to the real cost. Always compare loans using the comparison rate, which bundles the interest rate and fees into a single percentage.
Learn more in our Comparison Rates Explained guide.
Borrow less than you're approved for, keep the term under 5 years, and always compare at least three lenders before signing. The cheapest car loan is the one you don't need.
Quick Answers
How do lenders decide how much I can borrow?
Lenders look at your income, existing debts, living expenses, credit score, and the loan-to-value ratio (LVR) of the car. Most cap your total monthly debt repayments at 30% of your gross monthly income (the debt-to-income ratio).
What credit score do I need for a car loan?
Most mainstream lenders want a score above 600 (Equifax). Above 700 gets you better rates. Below 500 and you'll be looking at specialist lenders with higher rates. Check your score for free at getcreditscore.com.au.
Can I borrow 100% of the car's price?
Some lenders will finance 100% if you have a strong credit score and stable income, but most prefer you to have a 10–20% deposit. A larger deposit reduces your LVR and usually gets you a better interest rate.
Does using a calculator guarantee I'll be approved?
No. A calculator gives you an estimate of repayments and borrowing capacity, but actual approval depends on the lender's full assessment of your financial situation, credit history and the vehicle.
