How much can I borrow for a car loan?
"How much can I borrow car loan" is one of the most common searches before Australians visit a dealership or apply online. Lenders do not simply multiply your salary by a magic number — they measure whether you can afford repayments after tax, living costs and other debts. This car loan eligibility calculator uses a simplified debt service ratio (DSR) approach: a percentage of your gross monthly income is allocated to car loan repayments, minus existing monthly commitments you declare.

The default 30% DSR reflects a conservative planning figure many brokers use for consumer car finance, though individual lenders may allow more or less depending on credit score, employment stability and whether the loan is secured. Adjust the DSR slider if you want a stricter personal budget (25%) or to model a more generous lender policy (35%). The output is a maximum loan principal at your assumed rate and term — not the drive-away price, because you may also contribute a deposit or trade-in.
What counts as existing debt?
Include minimum monthly payments on credit cards, personal loans, buy-now-pay-later facilities, existing car loans and any other committed repayments. Lenders often assess credit cards at 2–3% of the limit per month even if you pay in full, so your actual approved amount may be lower than this calculator shows if you carry unused limits. HECS-HELP is treated differently by each lender; some ignore it, others shade repayments into serviceability.
If you are replacing a car, enter only debts that will remain after the new loan starts. Trading in a vehicle with finance still owing reduces your net borrowing capacity because the payout must be cleared. A broker can help structure refinance and purchase as one transaction; this tool assumes a clean-slate new loan for simplicity.
Car loan affordability beyond the maximum
Eligibility and affordability are not the same. You might qualify for $60,000 but feel comfortable with $40,000 once insurance, fuel, registration and maintenance are included. After using this calculator, subtract those running costs from your household surplus. A cheaper car with a shorter term often beats stretching to the maximum loan with a longer horizon — total interest drops sharply when you borrow less or repay faster.
Secured car loans generally offer lower rates than unsecured personal loans because the vehicle is collateral. Enter the secured rate you have been quoted; if you only have an unsecured indicative rate, expect the maximum affordable loan to shrink because the same monthly payment supports a smaller principal at higher interest.
How lenders assess car loan applications
Real car loan eligibility checks add layers this tool omits: credit file scoring, employment type (casual vs permanent), residential status, vehicle age limits and whether the asset is for business use. Lenders also apply a buffer above your contract rate — if you are quoted 8.5%, they might assess repayments as if the rate were 10% or higher. That assessment rate caps borrowing more aggressively than a straight repayment formula.
Novated leases, chattel mortgages and commercial hire purchase follow different tax and serviceability rules. This calculator suits standard consumer secured and unsecured car loans. Business buyers should speak to an accountant about GST, depreciation and fringe benefits before relying on consumer DSR maths.
Using your results at the dealership
Walk in with a pre-approved range and you negotiate from strength. If the calculator shows $45,000 maximum at five years and 8.5%, you know a $55,000 car needs a larger deposit or longer term — each change has a cost. Compare dealer finance against your bank and specialist lenders; the lowest rate with acceptable fees wins, not the convenience of on-the-spot approval alone.
Revisit this car loan eligibility calculator whenever your income, debts or interest rates change. A pay rise or paying off a credit card can materially increase capacity. Conversely, rising rates shrink what the same income supports — update the rate field to stay current. The goal is a repayment you can sustain for the full term, not just the first year.
Tips before you apply
✅ Best practices
- Compare multiple quotes using the same loan amount and term
- Check your credit profile before applying for better rates
- Review the amortization schedule for total interest cost
- Keep an emergency fund — do not max out affordable payment limits
