FAQ
How does the car loan calculator work?
Just pop in a loan amount, term, and interest rate, and the calculator will show you estimated weekly, monthly, and total repayments. It’s a quick way to see how different scenarios could look. These figures are a guide only — your exact rate and repayments will be confirmed once we’ve reviewed your application.
How do I calculate my car loan repayments?
Repayments are worked out using your loan amount, the length of the loan (term), the interest rate, and example fees. The calculator runs the numbers for you, applying a standard repayment formula so you can get an idea of what you might pay over time.
What interest rate should I use in the calculator?
If you're not sure, use a rate within our current range as a starting point - you'll find it in the Loan Information section below. It's a guide only. Your actual rate is personalised, based on things like your credit history and the loan details, and it's confirmed after we assess your application.
What affects my repayment amount?
Several things can change your repayments: the loan amount, the interest rate, the term, and any fees. A longer term can make each payment smaller but increase the total cost, while a shorter term usually means higher payments but less interest overall.
Why do fees affect the total cost?
Most loans include an establishment fee, an introducer fee, and sometimes other charges. These get added to your loan balance, so they're included in the repayment calculation - which is why they affect the total you'll repay over the term.
Can I change the loan term to see different repayment amounts?
Absolutely. Adjusting the term in the calculator will instantly update your estimates. It's a simple way to see how spreading the loan over more time, or paying it off faster, could fit your budget.
Is the rate shown in the calculator the rate I'll get?
Not necessarily. The calculator uses whatever rate you enter, so it's an estimate, not a quote. Your actual rate is personalised - it depends on things like your credit history, the loan details, and the security on the loan - and it's confirmed once we've assessed your application.
How accurate are the calculator results?
They're designed to give you an estimate based on the numbers you enter. Your actual interest rate, fees and repayments will be determined after your application is assessed.
Does using the calculator affect my credit score?
No. The calculator is just a tool for estimating repayments - using it doesn't involve an application or a credit check, so it has no effect on your credit score. A soft check only happens later, if you decide to start an application.
