Summary

Managing car loan debt can be challenging, especially with the ongoing costs of running a car such as petrol, insurance, WOF and parking. If you fall behind on loan repayments, the costs can jump up with penalties and late charges.
Too many New Zealanders have expensive car loan, and it's not going away - this March 2022 story from Stuff.co.nz explains how fall behind on car loan repayments.
To help you understand the long-term costs associated with a car loan, we've created this Car Loan Amortisation Calculator.

How to Use the Calculator
Insert the following details:

Your Car Loan Debt: The current balance owing on your car loan.
The Term: The number of years you plan to pay off the car loan.
The Interest Rate: The annual interest rate you are charged.
The Start Date: The date you begin making payments.

Example Calculation for Car Loan

John is considering taking out a car loan of $10,000, which he plans to repay over three years at an interest rate of 15.00% per annum, starting from today. Using these figures in our car loan calculator, the following results are obtained:

Monthly Payment: $347 (this is an estimate and actual payments may vary based on loan terms)
Total Payments Over 60 Months: $12,480
Total Interest Paid: $2,480

This example helps illustrate the financial commitment involved in taking out a car loan, helping you plan your finances accordingly.

Important Considerations

Fixed repayments: The calculations assume that you make the same car loan repayment for the entire repayment period.
Stable interest rate: The interest rate is assumed to remain constant without any increase or decrease.
Consistent payments: It is assumed you do not miss any repayments, overpay, or underpay during the term.
