Understanding Car Loan Interest in Australia
Car loan interest is calculated based on the loan amount, interest rate, and loan term. The interest rate is one of the most important factors affecting your total loan cost in Australia.
How Car Loan Interest is Calculated in Australia
Most Australian car loans use a reducing balance method, which means interest is calculated on the remaining balance of your loan, not the original amount. As you pay down the principal, you'll pay less interest over time.
