Worked example

Suppose you finance $35,000 (the drive-away price less your deposit) at 8 percent APR over 5 years. The calculator turns the 8 percent into a monthly rate of about 0.6667 percent and spreads the loan across 60 repayments. The amortising formula gives a monthly repayment of roughly $709.67. Across all 60 payments you repay about $42,580, so the total interest is close to $7,580 on top of the amount financed. A larger deposit lowers the financed figure and cuts both the monthly repayment and the interest, which is why putting more down at the start is the simplest way to reduce the cost of a car loan.

How it is calculated

The car loan uses the same fixed amortising formula as a standard term loan. It takes the amount financed, divides the APR by 12 to get a monthly interest rate, and treats the term as a count of monthly payments. The monthly repayment is the level amount that clears the balance over the full term while charging interest on the outstanding balance each month. Total paid is the monthly repayment times the number of payments, and total interest is that total minus the amount financed. The calculator works on the amount financed, so reduce the price by your deposit and any trade-in before entering it. Secured car loans usually carry lower rates than unsecured personal loans because the vehicle acts as security, and a novated lease can change the picture again for eligible buyers by using pre-tax salary.

Frequently asked questions

Novated lease vs auto loan?
A novated lease bundles the vehicle cost and running expenses through salary sacrifice, reducing your taxable income. Electric vehicles eligible for the FBT exemption introduced in 2022 make novated leases especially attractive. A standard auto loan gives you outright ownership from day one and carries no FBT considerations. Compare the after-tax cost of each option using your marginal tax rate before deciding.
Is car loan interest tax deductible in Australia?
Interest on a car loan is only deductible to the extent the vehicle is used for income-producing purposes, such as a sole trader using the car for work. Private use of the vehicle is not deductible. If you use the car partly for work, you can apportion the interest using your logbook percentage or the ATO cents-per-kilometre method. Employees generally cannot claim car loan interest as a deduction.
What APR should I expect on an Australian car loan in 2025-2026?
Secured new-car loan rates from banks and credit unions typically range from around 6 percent to 12 percent per annum depending on the lender, your credit score, and the loan term. Dealer finance can be higher, sometimes above 14 percent, so compare comparison rates rather than headline rates. The comparison rate includes fees and is a more accurate measure of the true annual cost. Pre-approval from your bank before visiting a dealer gives you a benchmark to negotiate against.
Does a larger deposit meaningfully reduce the total interest paid?
Yes. Every dollar of deposit reduces the amount financed, which reduces the base on which interest compounds each month. On a $35,000 loan at 8 percent over five years, increasing the deposit by $5,000 saves roughly $1,085 in total interest. A larger deposit can also qualify you for a lower interest rate because the lender takes on less risk. Paying down the loan early or making fortnightly rather than monthly repayments produces a similar compounding benefit.
