  • You’d borrow $185,400 and pay $3,320.17 a month for 60 months, then a $36,000 balloon.
  • Interest adds $49,810, so the truck costs $235,210 in total.
  • Without the balloon the payment would be $3,803.76 a month, but you’d pay $6,984 less interest. Plan how you’ll pay or refinance the balloon before it falls due.
  • At 12,000 km a month, the finance alone costs $0.277 per km before fuel, insurance, tyres and maintenance.
  • On a chattel mortgage a GST-registered business can usually claim the GST in the price on its next BAS.

Your result, explained

You would finance $185,400 and pay $3,320.17 a month, with $36,000 still owing at the end. Interest adds $49,810, so the truck really costs $235,210 in total.

Lenders will want your ABN, HR/HC/MC licence, BAS or tax returns and bank statements, plus the dealer quote or bill of sale with the VIN and proof of insurance. A bigger deposit, two years’ driving experience and steady freight contracts are what move your rate the most.

How the payment is worked out

The amount financed is the truck price plus any tax and fees you roll in, minus your deposit and trade-in. With no balloon, each monthly payment is P × r ÷ (1 − (1 + r)−n), where P is the amount financed, r the monthly rate and n the number of months.

A balloon (also called a residual or final payment) is a lump sum left owing at the end. Because you don’t repay that part until the last month, it lowers every monthly payment, but you pay interest on it for the whole term, so total interest goes up.

How to get truck finance in Australia, step by step

  1. Hold the right licence class. LR for trucks over 4.5 t up to 8 t GVM, MR for two-axle rigid trucks over 8 t, HR for rigid trucks with three or more axles, HC for prime movers with a semi-trailer and MC for B-doubles and road trains. Licence classes are the same in every state.
  2. Get an ABN and register for GST (needed to claim GST credits and for most commercial lending). Low-doc lenders often want an ABN that is at least 1–2 years old.
  3. Choose the finance type: chattel mortgage (you own the truck from day one), commercial hire purchase, finance lease or a consumer loan if it’s not for business.
  4. Decide on a balloon. Many lenders allow 20–40% depending on the term and the truck’s age. It lowers repayments but leaves a lump sum to pay or refinance.
  5. Get quotes and apply through a broker or lender with the documents below. Before buying used, search the PPSR for money owing.
  6. Register and insure the truck with the lender noted as an interested party, then settle.

Rates, balloons and GST

Truck finance rates are usually fixed. Established ABN holders with good credit and a newer truck get the sharpest rates; low-doc, older trucks and bad credit cost more. Many deals need no deposit. On a chattel mortgage a GST-registered business can usually claim the full GST in the price on its next BAS, and claim interest and depreciation as deductions. Stamp duty on heavy vehicles is set by each state, commonly around 3%.

Frequently asked questions

Can I get truck finance with a new ABN?

Yes. Some lenders accept a new ABN if you have industry experience, a contract and good credit, but you may need a deposit or a lower balloon.

What is a balloon on truck finance?

A lump sum owed at the end of the term, set as a percentage of the price. It lowers the repayments; when it falls due you pay it, refinance it or trade the truck in.

Chattel mortgage or hire purchase?

With a chattel mortgage you own the truck straight away and the lender holds security over it. With hire purchase the lender owns it until the last payment. Most GST-registered businesses choose a chattel mortgage for the upfront GST claim.
