repayments
Your estimate repayments are calculated based on the loan type, loan amount, loan term and your credit score entered. The calculations do not include upfront or continuing credit fees and charges. Lending is to approved applicants only. All lending is subject to a detailed credit assessment, the results from this calculator do not constitute a loan application or variation to an existing facility, loan offer or loan approval.
Your contracted personal loan repayments will be set to a monthly frequency, meaning you will need to meet the agreed repayment amount by the due date stated on your loan contract each month. To meet this minimum monthly amount, you can however make repayments weekly or fortnightly.
This calculator provides general information only and should not be relied on to make a decision about a financial product. You should consider obtaining advice from an appropriately licensed financial services professional before making any financial decisions.
A secured loan is 'secured' against the asset you are borrowing for, such as a car. If you are unable to repay the loan, the lender can sell the asset to cover the costs of the loan.
An unsecured personal loan is a loan that does not require an asset as security. Your income and ability to repay the loan is still assessed, however you don't need an asset to secure the loan.
Your credit score is a number used by lenders to assess how likely you are to repay a loan. Your score is based on the information in your credit report, including:
- How you've managed previous loan and credit card repayments.
- How many loan applications you've made in the past.
- The age of your credit file.

A personalised interest rate is determined in large part by your credit score. This is based on a range of factors including your history of repaying loans, credit cards, and other bills. In short, the better your credit score, the lower the interest rate you’re likely to be offered.
Speaking of which, it's worth noting that while submitting a full application will likely result in a small, temporary dip to your credit score, simply getting your estimated personalised rate will not impact it.
A secured loan is 'secured' against the asset you are borrowing for such as a car, or home. If you are unable to repay the loan, the lender can sell the asset to cover the costs of the loan. Most secured personal loans have a lower interest rate when compared to an unsecured personal loan because there is an asset attached.
An unsecured personal loan is a loan that does not require an asset as security. Your income and ability to repay the loan is still assessed, however you don't need an asset to secure the loan.
If you’re buying a green vehicle under seven years old, a Great Southern Bank Green Car Loan may be right for you.
If a vehicle does not meet the green car eligibility criteria, you may be interested in a Secured Fixed Car Loan or an Unsecured Fixed Personal Loan if you’re buying a car older than seven years.
Some lenders offer car loans with balloon payments. A loan with a balloon payment is typically lower as you’re repaying a portion of the loan plus interest. But at the end of the loan term, you’ll have to pay a lump sum (the balloon payment), which is the remaining balance on your loan. You’ll have to set some money aside to make the balloon payment, so it’s important you calculate the full cost to avoid paying more in the long term.
Our car loans don’t come with balloon payments, so you know what you’re getting from the start. It pays to compare car loans to find the one that’s right for you.
The term ‘car finance’ refers to the different ways you can borrow money to buy a car.
If you don’t have the money to pay for a car upfront, then financing it with a car loan is a clever way to borrow the amount you need, and pay it off in small, flexible repayments.
It’s important to note that car loans attract interest on top of your regular repayments. The interest rate will vary between lenders, so it pays to compare.
When you apply for a car loan, we will assess your income and expenses to ensure you can pay it off. Then when it’s time for settlement, we will pay the seller directly and you’ll officially own your car.
Buying a car is exciting, but it also comes with a few ongoing costs to keep your car on the road. In addition to your:
- Petrol
- Regular servicing (approx. every 6 months)
- Car Insurance
- Set aside some savings for emergency repairs - better to be safe than sorry.
Maintaining your car not only keeps your car safe and reliable, but it can also save you money on bigger repairs further down the track. And avoid the inconvenience of having to get around while your car is at the mechanic.
