Car Finance Decision Calculator — Compare Instalments, Balloon & GFV
Car Finance Calculator — Compare Instalments, Balloon, GFV & Extra Payments
Buying or financing a car can be confusing when the monthly instalment looks affordable, but there are balloon payments, GFV amounts, fees, interest and other running costs sitting in the background.
This Excel calculator helps you look at the full picture before making a decision.
You can use it to compare normal instalment finance vs GFV / lease-style finance, see how different balloon amounts affect your monthly payment, test extra payments, estimate how much interest you could save, check what may still be owing at the end of the term, and understand the real monthly cost of the car once you include things like insurance, fuel, tracker, maintenance and other running costs.
It also includes tools to help you assess trade-in shortfalls, positive or negative equity, lump-sum payments, reducing your instalment, reducing the amount left at the end, and comparing finance quotes.
The calculator is designed to help you answer questions such as:
- What will my monthly car payment really be?
- Should I choose normal finance or a GFV-style deal?
- What happens if I use a 20%, 30% or 40% balloon?
- How much will I have paid after 48 months?
- How much could still be owing if I trade the car in before the finance term ends?
- What happens if I pay extra every month or make a lump-sum payment?
- How much of my take-home pay is actually going towards the car once I include fuel, insurance and other costs?
What you receive: an easy-to-use Excel spreadsheet with editable input cells and automatic calculations.
This calculator is for educational and scenario-planning purposes. Actual lender quotations, settlement amounts, fees, interest calculations and contract terms may differ, so always confirm final figures with your bank, dealership or finance provider.
