The number on your screen above is a repayment estimate. It is a useful starting point, but it does not tell you the one thing that actually defines a chattel mortgage: who owns the truck or the machine while you are paying it off. A repayment figure looks the same whether you are buying the asset or hiring it. The structure underneath it is what changes what you own, what you owe at the end, and what you can do with the asset along the way.
So before you take the estimate at face value, it is worth understanding what that figure is describing. A chattel mortgage repayment is built from the amount financed, the term, the rate a lender offers you, and whether you have parked a lump sum at the end. Move any one of those and the monthly figure moves. The calculator lets you feel that. This page explains the structure sitting behind it, so the estimate means something when you read it, and so you know which levers are yours to pull.
What a chattel mortgage actually is
Under a chattel mortgage, your business owns the asset from the day it is delivered. The truck, the excavator, the trailer, the tank and bowser setup goes onto your books as yours from the start. The lender advances the money to buy it and takes a registered security interest over the asset until the loan is repaid. That security interest is recorded so anyone checking can see the asset is financed, and it gives the lender the right to recover the asset if the loan is not paid.
That is the difference from a lease. Under a lease, the financier owns the asset and you pay to use it. You do not hold title during the term. With a chattel mortgage the ownership is yours the whole way through, and the lender's claim is a security interest rather than ownership.
"Chattel" just means a movable item of property, which is what most trucks and equipment are. "Mortgage" here means the security taken over that item. Put together, it is a loan to buy a piece of business equipment, secured against the equipment itself.
Why ownership makes this the common structure
Because the business owns the asset from day one, a chattel mortgage lines up neatly with how most operators think about their gear. You bought it, it is yours, it earns for you, and you are paying down a loan against it. That ownership is also why the structure carries the tax and accounting treatment it does, though the specifics of that depend entirely on your business, not on the asset, which is covered further down.
The security being tied to the asset is also why lenders can price these deals the way they do. There is a tangible, recoverable thing behind the loan. A well-kept truck with clear resale demand is straightforward security. A specialised or older item is still security, but a lender weighs how easily it could be sold and what it would fetch if things went wrong. That assessment feeds into what a lender offers, which is exactly why the rate in the calculator is a placeholder until a lender has looked at your actual deal.
If you want the fuller picture of how lenders assess an application and reach different funders, what an asset finance broker actually does walks through the process. It is also worth understanding how the security itself is documented and what a lender needs from you to progress a file, which the equipment finance documents checklist sets out in practical terms.
How a balloon or residual sits inside the figure
This is where the repayment estimate can mislead if you do not know what you are looking at. A balloon, sometimes called a residual, is a lump sum you agree to leave owing at the end of the term rather than paying it down across the months.
When you set a balloon in the calculator, the monthly figure drops. That looks attractive, and for cash flow it can be. But the money has not gone anywhere. You are paying down less of the loan each month, so a larger amount is still owing when the term ends. A repayment figure with a big balloon behind it and the same figure with no balloon are two very different commitments, even though they read similarly on screen.
So when you move that balloon slider, watch both numbers. The monthly comes down, and the amount left at the end goes up. There is no free saving in it. You are choosing between more paid now and less owing later, or less paid now and a lump to deal with at the end. The right balance depends on how the asset earns, how long you expect to keep it, and what your cash flow looks like across the term.
A chattel mortgage balloon calculator is genuinely useful for exactly this reason. It lets you test the trade-off before you commit to a structure. What it cannot do is tell you the rate a lender will actually offer against your business and your asset, which is the other half of the real figure. A chattel mortgage repayment calculator is a modelling tool, not a quote, and treating it as a quote is where operators get caught out.
The end of term fork
When the term finishes and there is a balloon owing, you have three broad options.
You can pay the lump out. The asset is then fully yours with no finance against it, and the security interest is released. This suits operators who planned for the balloon and set money aside, or who had a strong run and want to clear the debt.
You can refinance the balloon. The remaining amount becomes a new, smaller facility over a further term. This keeps the asset working and spreads the final lump, though it means continuing to carry finance and paying to do so. Whether a lender will refinance depends on the asset's age and condition at that point and on how your business is travelling.
Or you can sell the asset. If you are upgrading or exiting, the sale proceeds go toward clearing what is owed, including the balloon. If the asset sells for more than the payout, the surplus is yours. If it sells for less, you cover the shortfall. This is where the balloon decision made years earlier shows up: a large balloon leaves more owing against a sale price that has come down with age and hours.
Thinking about which of these three you are most likely to take, before you sign, is what makes the balloon decision a considered one rather than a default.
What the security interest means if you sell early
Because the lender holds a registered security interest, you cannot pass clear title to a buyer while the loan is outstanding. In practice, selling an asset mid-term means arranging a payout with the lender so the security is released as part of the sale. A buyer, or their financier, will check the register and will want the interest cleared before money changes hands.
This is manageable and happens constantly. It just means an early sale is a coordinated transaction, not a private handshake. The payout figure a lender gives you is built from the amount still owing plus any costs of ending the facility early, and it moves depending on when you do it and whether a balloon sits behind the loan. Paying out asset finance early covers how those payout figures are put together and what to check before you commit to a sale date.
If the finance sits behind a company and directors have given guarantees, an early exit or refinance can touch those too, so it is worth knowing what director guarantees actually expose before you restructure a deal.
Where the GST and tax questions go
A chattel mortgage carries GST and tax consequences, and operators reasonably want to know how the purchase and the repayments are treated. Those answers depend on your business: how you are registered, how you account for GST, how the asset is used, and what your overall position looks like. They do not depend on the asset itself, which is why no calculator and no page can give you a figure you should rely on.
Send those questions to a registered tax agent, or check the current rules with the Australian Taxation Office. A tax agent applies the treatment to your actual circumstances, which is the only way the answer is worth anything. Do not take a tax figure off a repayment tool.
Turning the estimate into a real deal
The calculator gives you a feel for the shape of a repayment and lets you test what a balloon does to it. What it cannot supply is the rate, the fees, or the terms a lender will actually put against your business and your asset. Those come from a lender looking at your file: your ABN history, the asset, how it will earn, and how the deal is structured.
That is what the quote form is for. You can request three free quotes at /quote/ and get real figures on your own deal, structured the way you want to test it, including with and without a balloon. If you are weighing the calculator against a specific asset class, the truck finance guide, the equipment finance guide and farm machinery finance each cover what lenders look for in those markets.
