Rego calculator

One car, every state

Every state builds a rego bill differently: by weight, by cylinders, by engine size, by emissions or at a flat rate, with the injury insurance set by government in some places and by competing insurers in others. The calculator puts your car through your state’s own fees, line by line.

A four-cylinder car with a 1,400 kg tare and a 1.5 to 2 litre engine, privately registered in the capital, renewed for 12 months. Where insurers compete for the compulsory cover, the figure uses the lowest published premium.

On that car the cheapest of the fully priced states is Tasmania, $643, and the dearest is Victoria, $959. Two figures are not complete totals. The ACT’s leaves out its Motor Accident levy, whose amount for 2026–27 could not be confirmed, and does not take off the 2% discount its fee determination gives a 12-month registration fee paid in full, because how Access Canberra applies it is unconfirmed. NSW’s $375 is everything but the green slip, which has no published price.

New South Wales: what the bill is made of

A NSW renewal has four parts: the registration fee, the motor vehicle tax, a green slip bought separately from a private insurer, and, for a car more than five years old, a safety check. Everything but the green slip is published, so the calculator adds those parts up and takes your green slip quote for the rest.

The regulation counts the tax in units, and on 1 July 2026 an amending regulation replaced its whole table with new counts. Each one is last year’s raised by Sydney’s inflation, which is why the band that paid $380 now pays $391. Transport for NSW publishes the new table as its 2026–27 tax. The regulation’s separate rule that raises the value of a unit each year was left as it was, so read literally it would raise the tax a second time, to about $403; no official source applies that, and the amending regulation describes a single rise. Until 4 October 2026 this page said Transport for NSW’s table was out of date; it was not, and the corrections page says how we found out.

The insurance is most of the bill

Every state makes injury insurance part of registration, and in most it is the biggest line. Victoria, WA, Tasmania and the Northern Territory each run a single government scheme: WA, Tasmania and the NT charge one price for a private car, and Victoria prices it by where the car is garaged. Queensland, South Australia and the ACT let licensed insurers compete. Queensland and South Australia keep premiums within limits their regulator sets; Queensland and the ACT publish every insurer’s price, and South Australia publishes the lowest. The calculator starts from the lowest and takes your quote instead. NSW goes furthest: green slips are priced on the driver, so two neighbours with the same car can pay quite different amounts.

Shorter terms cost more over a year

Victoria, Tasmania and the Northern Territory publish how every part of a three- or six-month renewal is worked out, and in all three two half-years cost more than one year: a service fee, an administrative fee or an administration fee is charged on each payment. The Northern Territory prints every amount. Tasmania charges each part by the day, so its figure depends on how many days your period runs, and the calculator says which count it uses. The other states offer short terms too, but at least one part of a short-term bill in each, mostly the insurance, could not be confirmed from a published source, so the calculator shows them for 12 months only rather than guess.
