How this calculator works
Calculate monthly car loan repayments and total interest using the standard amortisation formula. Enter the vehicle price and deposit or trade-in to derive the loan amount, then adjust the rate and term to compare finance options.
Calculate car-loan repayments and total interest
Enter the car price and deposit or trade-in separately; the calculator subtracts the deposit to find the amount financed. It then applies the annual interest rate and loan term using reducing-balance repayment maths.
A longer term usually reduces each repayment but increases total interest. Compare more than one term and rate so the lowest monthly amount does not hide a substantially higher overall cost.
Check the comparison rate, fees and balloon payment
The advertised interest rate may not include establishment, monthly, early-repayment or dealer fees. Australian lenders publish a comparison rate for a standard example, but your own loan amount and term can produce a different effective cost.
This calculator does not include a balloon or residual payment. If an offer has one, add that final lump sum when comparing total cost and make sure the end-of-term amount remains affordable.

Frequently asked questions
Should I include a balloon payment?
This calculator assumes no balloon. A balloon lowers repayments but leaves a large lump sum owing at the end.
Are fees included?
No. Add establishment, account, early-exit and other lender fees separately when comparing the total cost of finance.
Is a dealer rate competitive?
Compare the comparison rate, not the headline rate, across dealers, banks and credit unions.
