Car Finance Calculator Australia

What Is a Car Finance Calculator?

A car finance calculator is an online tool that helps you estimate your monthly car loan repayments before applying for a loan. It’s an essential resource for car buyers in Australia, where car financing terms and interest rates can vary significantly across different banks and dealerships.

By entering details like vehicle price, deposit, loan term, and interest rate, you can get an instant estimate of your loan repayments, enabling you to plan your budget with confidence.

How the Car Finance Calculator Works

The car finance calculator uses a standard amortization formula to estimate your loan repayment schedule. This method is widely used by lenders to calculate loan repayments based on the principal, interest, and term.

Amortization Formula Used by the Calculator:

M = P × r (1 + r)^n / ((1 + r)^n – 1)

Where:

• M = Monthly repayment

• P = Principal loan amount (total cost minus deposit)

• r = Monthly interest rate (annual rate ÷ 12)

• n = Total number of monthly payments (loan term × 12)

This formula ensures you get an accurate estimate of your monthly repayment and the total repayments, including both principal and interest. It helps you understand the true cost of your loan over time.

Step-by-Step: How to Use the Calculator

1. Enter the Car Price — Include the total on-road cost or dealership quote for the vehicle.

2. Add Your Deposit or Trade-In Value (if applicable).

3. Choose Your Loan Term — In years, typically ranging from 1 to 7 years in Australia.

You can adjust the values to compare different loan terms or interest rates to find the best deal for your situation.
