What is a chattel mortgage?
A chattel mortgage is a business finance product where you borrow to purchase movable property — most commonly vehicles, trucks, trailers or machinery — and the lender takes a mortgage over the asset as security. Unlike a consumer car loan in your personal name, a chattel mortgage calculator must account for GST treatment, deposit structure and often a balloon payment aligned with the asset's residual value. This tool models those elements so you can estimate cash flow before speaking to your accountant or finance broker.

Registered businesses registered for GST may claim input tax credits on the GST component of the purchase price, subject to ATO rules and apportionment if the asset is partly private use. The GST toggle above lets you enter either an inclusive or exclusive price — the calculator splits out the GST component for transparency. Tax outcomes are not automatic; always confirm with your tax adviser.
Chattel mortgage repayment calculator
The chattel mortgage repayment calculator uses standard amortisation on the amount financed after your deposit. Monthly repayments cover interest on the outstanding balance plus principal reduction. When you enable a balloon, instalments are calculated so a specified percentage of the original loan remains owing at the final payment — common for vehicles where you expect to sell, trade or refinance at end of term.
Compare balloon versus fully amortising structures: balloons improve short-term cash flow but increase total interest and leave a lump sum to manage. For heavy vehicles with predictable resale markets, balloons near published residual guides are standard; for specialised equipment with uncertain resale, a lower balloon or none at all may be prudent.
Car chattel mortgage calculator for fleets
A car chattel mortgage calculator is the starting point for sole traders and companies replacing work utes, vans or passenger cars. Finance the drive-away price (including GST if quoted inclusive), subtract any cash deposit or trade equity, and model the term that matches your accounting depreciation policy. Interest is generally tax-deductible to the extent the vehicle is used for business; principal is not deductible but reduces your loan balance over time.
Chattel mortgage differs from hire purchase (where the lender owns the asset until final payment) and from novated lease (an employee benefit structure). Ownership from day one under chattel mortgage means the asset sits on your balance sheet and you claim depreciation — the calculator handles repayment maths only, not balance sheet presentation.
GST and chattel loan structures
When price excludes GST, the finance amount often includes GST because that is the cash outlay to the supplier. When price includes GST, the full sticker price is financed minus deposit. BAS reporting and input credit timing affect your working capital separately from the repayment schedule shown here. Some lenders offer structured payments (e.g. seasonal businesses); this calculator assumes level monthly instalments.
Insurance, registration and fitting costs can be bundled into chattel finance if the lender agrees — add them to the asset price field for a combined repayment estimate. Establishment fees may be financed or paid upfront; if financed, include them in the amount borrowed.
Choosing terms and rates
Asset finance rates depend on age of vehicle, business strength, industry and whether the loan is secured solely by the asset or backed by property. Terms from one to seven years are typical; longer terms mean lower payments but more interest and potential mismatch if the asset is worn out before the loan ends. Use this chattel loan calculator to align repayment with expected useful life and resale value.
Before signing, compare at least two finance proposals on the same price, deposit and balloon settings. Small rate differences matter on commercial-sized loans. Pair this repayment estimate with your accountant's view on GST and depreciation for a complete picture of the true cost of acquiring your next business vehicle.
Tips before you apply
✅ Best practices
- Compare multiple quotes using the same loan amount and term
- Check your credit profile before applying for better rates
- Review the amortization schedule for total interest cost
- Keep an emergency fund — do not max out affordable payment limits
