Cost over the period	Petrol	Electric

Plug-in electric cars pay no stamp duty up to $50,000 and 3% of the amount above it, against 3% of the whole price for petrol cars. The concession runs to 30 June 2027.
The electric car gets free registration (it still pays the CTP charge) for the first year. After the concession ends, this comparison assumes it pays the same as a 4 cylinder car of 1,501 to 3,000 cc. That later fee is an assumption, not a published figure.
Insurance, tyres, depreciation and home charger installation are left out unless you add them under servicing or resale.
