On-road costs on top of the car price:
This is an estimate based on published duty rates for light passenger vehicles. It isn't financial advice. Your state's revenue office or registration authority decides the duty you pay, so check the official source.
What are on-road costs?
On-road costs are the government charges and dealer fees you pay on top of a car's price to get it registered and driving. When a dealer quotes a "drive-away" price, these are already included. When the price is "plus on-roads", you'll pay them on top.
The main pieces are:
- Stamp duty (called motor vehicle duty, vehicle licence duty or registration duty depending on the state). It's charged once when the car is registered or transferred, and it's usually the biggest on-road cost. This calculator works it out from each state's published rates.
- Registration, plus compulsory third party (CTP) insurance, which is bundled into rego everywhere except NSW, where you buy a green slip separately. Rego depends on the car's weight, engine or emissions and where you live, so get the figure from your state's registration calculator or your quote.
- Dealer delivery, which covers the dealer's pre-delivery preparation. It's a dealer charge, not a government one, so it's often negotiable.
- Number plates and extras, like personalised plates, tinting or paint protection.
Every state counts duty differently. NSW, Queensland, Tasmania, the ACT and the NT charge per $100 of value, Victoria charges per $200, WA uses a percentage that slides between 2.75% and 6.5%, and South Australia uses stepped rates. Several states charge a higher rate on dearer cars, and Victoria, Queensland, the ACT and the NT have lower rates for electric or low emission cars.
Duty rates used in this calculator
Light passenger vehicles. "Or part" means any part of a $100 (or $200) counts as a full block. Last checked 28 October 2026.
| State | Rate |
|---|---|
| NSW | $3 per $100 or part up to $45,000. Above $45,000: $1,350 plus $5 per $100 or part over $45,000. Service NSW |

Worked examples
NSW: a $45,990 petrol hatch
The price is over $45,000, so duty is $1,350 plus $5 for each $100 or part over $45,000. The excess is $990, which is 10 blocks of $100. $1,350 + (10 x $5) = $1,400.
Victoria: an $85,000 new petrol SUV
$85,000 is above the 2026-27 threshold of $80,809 and not over $100,000, so the $10.40 rate applies to the whole value. $85,000 / $200 = 425 blocks. 425 x $10.40 = $4,420. If the same car were a low emission vehicle, it'd be 425 x $8.40 = $3,570.
WA: a $32,000 car
The value sits between $25,000 and $50,000, so R = 2.75 + (32,000 - 25,000) / 6,666.66 = 3.80 (rounded to 2 decimal places). Duty is 3.80% x $32,000 = $1,216.
Queensland: a $38,500 hybrid
Hybrids pay $2 per $100 or part. 385 blocks x $2 = $770. A 4 cylinder petrol car at the same price would pay 385 x $3 = $1,155.
Frequently asked questions
Is stamp duty included in a drive-away price?
Yes. A drive-away price includes stamp duty, registration, CTP and dealer delivery. A price marked "plus on-road costs" doesn't, so you'll pay those on top.
Which state's duty do I pay?
You pay duty in the state or territory where the car is registered, which is usually where you live, not where you buy it.
Do I pay stamp duty on a used car?
Yes. Duty applies when a used car's registration is transferred to you, based on the price paid or market value, whichever is higher. Some states use different rates for used cars, such as the ACT.
Do electric cars pay less stamp duty?
In some places. Queensland charges $2 per $100 for hybrids and electric cars, Victoria keeps low emission cars at the lowest rate at any price, the ACT has the lowest rate for zero emission cars, and the NT has a concession of up to $1,500 for battery electric and plug-in hybrid cars until 30 June 2027. NSW, WA, SA and Tasmania use their standard rates.
Is dealer delivery negotiable?
Dealer delivery is a dealer charge, not a government fee, so you can ask for it to be reduced or removed. Duty, rego and CTP are set by government and insurers.
Does luxury car tax count towards stamp duty?
Generally yes. The value used for duty is usually the price including GST and any luxury car tax. The 2026-27 luxury car tax threshold is $80,809, or $91,661 for fuel-efficient vehicles, according to the ATO.
Why doesn't the calculator work out rego?
Rego and CTP depend on the car's weight, engine or emissions, your postcode and your insurer, so a single figure per state would be misleading. Use your quote or your state's registration fee calculator and enter the amount.
