Monthly repayment by finance term

Match the term to the asset's useful life. Over-financing a 3-year asset for 7 years means paying for something that's already worn out.

Monthly repayment by residual %

Higher residual = lower monthly, but you owe a big lump sum at the end. Match it to the asset's expected resale value.

Check the Instant Asset Write-Off. Eligible assets may be 100% deductible in the year of purchase (current threshold varies: check the ATO). That changes the after-tax cost significantly. Always compare chattel mortgage against finance lease: different tax treatment, different cash-flow profile.

How it works

Equipment finance lets businesses acquire vehicles, machinery, technology, and other assets without paying the full cost upfront. In Australia, the main options are chattel mortgage (you own it, claim GST upfront), hire purchase (you own it after final payment), finance lease (lender owns it, you lease it), and operating lease (pure rental). Each has different tax, GST, depreciation, and cash flow implications. This calculator compares them so you can choose the best structure for your business.

Worked examples

Work Ute: Chattel Mortgage

A tradie buys a $65,000 (ex-GST) Toyota HiLux via chattel mortgage at 6.9% over 5 years, 20% residual.

Financed amount: $65,000. Monthly repayment: $1,102. Residual (balloon): $13,000 due at end. Total of repayments: $66,118; total paid including the balloon: $79,118. GST claimed upfront: $6,500. The vehicle is depreciated over its effective life and the interest is deductible, so the after-tax cost is lower; at $65,000 it is above the $20,000 instant asset write-off threshold.

Restaurant Equipment: Finance Lease

A restaurant leases $120,000 of kitchen equipment via finance lease at 8.5% over 7 years, no residual.

Monthly payment: $1,900. Total paid: $159,632. Total interest: $39,632. As a finance lease, the full $1,900/month is 100% tax-deductible. At 25% company tax, the after-tax cost is ~$1,425/month. No GST claimed upfront, but GST is embedded in the payments.

Questions people ask

What's the difference between a chattel mortgage and a hire purchase?
Chattel mortgage: you own the asset from day one, and it's registered in your name. The lender has a charge (mortgage) over it. Hire purchase: the lender owns the asset until all payments (including any residual) are made. Both allow GST claiming and depreciation. Chattel mortgage is more common for vehicles; hire purchase for other equipment.
Can I claim the Instant Asset Write-Off?
From 1 July 2026, the Instant Asset Write-Off is a permanent feature of the tax system (no longer an annually-renewed budget measure): businesses with aggregated turnover under $10 million can immediately deduct the full cost of eligible assets costing under $20,000 each, rather than depreciating them over several years. This applies to the total cost of the asset, regardless of the finance method used. Consult your accountant to confirm eligibility for your specific asset.
Should I lease or buy equipment?
It depends on what matters to the business. A chattel mortgage gives ownership from day one, an upfront GST claim and depreciation deductions. A lease keeps the asset off your hands at the end, with deductible lease payments, which can suit equipment that dates quickly. The calculator compares the cost of each on your figures.

The terms, in plain English

Chattel Mortgage
A finance arrangement where you own the asset from day one, with the lender holding a mortgage over it as security. You claim GST upfront and depreciate the asset.
Residual Value (Balloon)
A final lump-sum payment at the end of the finance term. Setting a residual reduces monthly repayments but means you owe a large amount at the end.
Finance Lease
An arrangement where the lender owns the asset and leases it to you. Payments are 100% tax-deductible. At the end, you can purchase the asset for a nominal amount, re-lease, or return it.
Instant Asset Write-Off
A permanent tax feature (from 1 July 2026) letting businesses with turnover under $10 million immediately deduct the full cost of eligible assets under $20,000 in the year of purchase, rather than depreciating over several years.
