How the Calculator Works & Assumptions
This calculator models a chattel mortgage using standard amortisation and the inputs shown. For product scope, eligibility and process context, read our business asset finance guide.
- Rate range: loaded from AFA’s published planning assumptions for the selected asset type and condition. Enter a known rate to replace the range.
- Balloon: calculated as a percentage of the amount financed, not the asset price. A larger balloon lowers scheduled repayments but leaves a larger lump sum at the end.
- Term: 1–7 years. Most business asset finance is written over 4–5 years.
- Fees: establishment and account fees vary by lender and are excluded from estimates.
All figures are estimates for general information only and do not constitute tax, legal or credit advice. Confirm tax treatment with your accountant and see official guidance from the ATO on the instant asset write-off, the ATO on claiming GST credits, and Moneysmart (ASIC).
Asset Finance Calculator FAQs
What is the difference between chattel mortgage and finance lease?
With a chattel mortgage the borrower owns the asset and the lender takes security. With a finance lease the financier owns the asset during the term. GST, deductions, residuals and end-of-term options differ. Compare the contract and obtain tax advice.
Which asset finance structure gives the best tax deduction?
There is no structure that always gives the best tax result. Eligibility depends on business use, GST registration, turnover, asset type, price and the rules for the relevant income year. This calculator models repayments, not a personalised tax outcome.
Can I claim GST on asset finance?
An eligible GST-registered business may be able to claim input tax credits for the creditable business-use portion. Cars can be subject to the GST car limit and other exceptions. Confirm the amount and timing with a registered tax agent.
What interest rates should I enter in the calculator?
For a broad estimate in 2026, try 7.0%–8.5% for new equipment chattel mortgage with an established business, 8.0%–10.0% for used equipment, and 9.0%–12.0% for start-up or lower-doc scenarios. Our licensed brokers can provide an exact rate quote after a quick assessment — use the Get a Quote button for a personalised rate.
Does the calculator show the real after-tax cost?
No. The calculator estimates finance repayments using the inputs shown. It does not determine eligibility for GST credits, deductions, depreciation or an instant asset write-off, and it does not replace accounting or tax advice.
