Car Loan Repayment calculator
This calculator helps you estimate how much your car loan repayments could be.
Repayment calculator: Any calculations made by you using this calculator is intended as a guide only. It is for illustrative purposes only and is based on the accuracy of the information provided. The calculation is not an offer of credit. The amount you can borrow may vary once you complete a loan application and all the details relevant to our lending criteria are captured and verified. The calculations should not be relied on for the purpose of making a decision whether to apply for a personal loan. Weekly and fortnightly repayment calculations - if your monthly repayments are $1000, fortnightly repayments are calculated by dividing $1000 by 2 and rounding up if required ($1000/2 = $500). Weekly repayments are calculated by dividing $1000 by 4 and rounding up if required ($1000/4 = $250).
