$80,000 car loan repayments.

At 7% indicative over 7 years with no deposit, an $80,000 car loan comes out at roughly $282 a week, or about $1,222 a month. Five years pushes the weekly to around $362; six years sits near $315. The rate the lender offers, any deposit, trade-in, establishment fees and monthly admin fees all move the final number. The calculator above computes the figure for any combination of inputs.

Five years keeps total interest around $15,000 at 7% indicative but demands $362 a week. Seven years eases the weekly to near $282 but pushes interest past $21,400. Eight years, where offered, drops the weekly further but extends the negative-equity period to roughly 30 months. Many buyers choose 6 or 7 years with a 15 to 20% deposit as the balance.

When the vehicle is used more than 50% for business. On a chattel mortgage, the GST component is typically reclaimable on purchase, the asset is depreciated on the business books, and loan interest is generally deductible, subject to the accountant's confirmation. A consumer car loan does none of that. At $80k the GST alone is around $10,400, so the structural difference can be material over a 5-year term. This is an accountant conversation for specific circumstances.

A chattel mortgage puts the vehicle on the business balance sheet and the business owns it at the end. An operating lease keeps the vehicle off-balance-sheet and typically includes a residual value that the lessor carries; at term end the vehicle is handed back or re-leased. Operating lease often suits fleets or businesses that want predictable monthly cost with no residual risk. Chattel mortgage often suits sole traders who want to own the asset.

At this amount 15 to 20% ($12,000 to $16,000) is standard, and lenders often price a better indicative rate inside that band. A deposit is generally taken as the cheapest protection against 20 to 25% year-one depreciation on a new premium SUV. Zero-deposit loans at $80k are possible but typically leave the balance underwater for most of the first 24 months, which bites if the car is written off or traded in early.

It depends on the month and the model. Manufacturer finance arms (BMW Financial Services, Mercedes-Benz Finance, Audi Finance) run promotional rates on specific stock near quarter-end and EOFY. A bank or specialist lender is usually more flexible on term, deposit and fees. An indicative broker rate alongside the dealer offer, compared on total cost over the full term including residual payments, is the comparison that holds up.
