Australian On-Road Costs
Pricing API
Calculate accurate drive-away pricing, taxes, registration, duties and dealer charges across every Australian state and territory with one API.
Built for automotive retail teams that need pricing customers can trust and engineers can integrate fast.
Polestar Australia uses the Vyro On-Road Costs API for accurate, state-by-state drive-away pricing.
Why on-road pricing is harder than it looks
Eight jurisdictions. Annual rate changes. Different charge structures for consumers, fleets, and concession holders. Most teams underestimate the maintenance burden until the first financial-year rollover fails silently.
Inconsistent drive-away totals
Customer-facing websites, showroom tools, and finance systems show different numbers for the same vehicle. Each team owns a different version of the truth.
State rules change, systems don't
Stamp duty rates, CTP structures, registration fees, and concession thresholds update at financial-year boundaries. Manual maintenance creates rollover risk.
Spreadsheets and rate cards
Teams rely on emailed rate cards and hardcoded logic that drifts from current government charges. Quoting error rate climbs silently.
Customer distrust from opaque totals
A single drive-away number is not enough. Customers and dealers create support tickets when they can't reconcile how the final figure was calculated.
What goes into an Australian drive-away price
The list price is the price of the vehicle itself. The drive-away price is the all-inclusive total a customer pays to legally drive it away — the list price plus statutory charges and dealer delivery. On-road costs are everything added on top of the list price to make the vehicle road-legal.
Stamp duty (vehicle registration duty)
A state government tax calculated on the dutiable value of the vehicle. Tiered by price band and charged at different rates in every state and territory — sometimes varying by vehicle type, fuel, or emissions.
Registration
The fee to register the vehicle for road use, set by the state or territory road authority. Often includes administrative and number-plate components and is adjusted at financial-year boundaries.
CTP / compulsory third party
Mandatory third-party personal-injury insurance required to register a vehicle. Its structure differs sharply by jurisdiction — from regulated flat rates to insurer-priced, demographic-rated premiums.
Number plates
The cost of standard issue plates (and any premium or custom plate options). A small but real line item that varies by state and plate type.
Government levies
Additional statutory charges that apply in some jurisdictions, such as road-safety or motor-accident levies. These are easy to miss in hand-built calculators.
Dealer delivery
The dealer's charge to prepare and deliver the vehicle. Not a government charge, but part of the drive-away total — so it belongs in the breakdown alongside statutory items.
Eight jurisdictions, eight sets of rules
Every Australian state and territory sets its own stamp-duty rates and thresholds, its own CTP structure, and its own EV and low-emission concessions or exemptions — and they change at financial-year boundaries. Per-state government calculators are accurate for a single manual lookup, but they don't scale to a national dealer network, configurator, or online-ordering flow. One API does.
Duty tiered by dutiable value; flat-rate CTP modelling by dealer and location.
Duty rates differ by vehicle type and price; distinct registration and levy structure.
Duty calculated by engine type and dutiable value; its own CTP scheme.
Tiered duty thresholds with state-specific registration and levy components.
Duty scaled by dutiable value across bands; separate licensing fees.
Duty tiered by value; registration and CTP set by Tasmanian rules.
Duty can vary by vehicle emissions rating; territory-specific charges.
Duty on dutiable value plus territory registration and levy components.
EV and low-emission concessions vary widely by jurisdiction — some states apply duty or registration concessions and exemptions, with their own eligibility rules and effective dates. The API exposes available concession types per jurisdiction so your frontend renders the right options instead of hardcoding a handful of cases.
Key Features Of Our On-Road Costs API
Nationwide On-Road Calculation
One API handles pricing rules across NSW, QLD, WA, SA, ACT, VIC, TAS and NT — date-aware and state-specific. No separate calculators, no manual overrides.
Transparent Statutory Breakdowns
Return line-item pricing with stamp duty, registration, CTP, government levies, and dealer charges separated. Auditable totals, not black-box numbers.
Real Automotive Pricing Inputs
Support dutiable value, on-road items, accessories, discounts, rebates, and dealer delivery — so API responses reflect actual quoting flows, not just MSRP.
Consumer and Commercial Quoting
Handle retail and fleet/commercial journeys in the same API. Different assumptions, same stable integration.
Concessions and Eligibility
Expose available concession types by jurisdiction so your frontend can render the right options before quote creation — not hardcode a handful of edge cases.
Single and Batch Quote Endpoints
Use POST /v1/quote for single calculations or POST /v1/quote/batch for configurators, comparison tools, and listing pages that need multiple quotes fast.
Date-Aware Rule Handling
Financial-year boundaries and future registration dates are handled explicitly. Choose strict failure or controlled prior-year fallback — no silent errors.
Simple Integration Model
Authenticate with API key or bearer token. Use a standard quote payload. Integrate into websites, configurators, showroom tools, or partner systems in days.
One pricing layer across every retail touchpoint
Whether you're building a national configurator, a dealer quoting tool, or a finance journey, the same API handles pricing consistently — so your totals never disagree across systems.

}Other Australian sources exist — this is the integration-first one
There are several good ways to research Australian on-road costs. Where the Vyro On-Road Costs API is different is that it's built to be embedded — a developer-friendly, batch-capable, configurator-ready pricing layer rather than a manual lookup tool.
State & territory government calculators
Authoritative for a single jurisdiction and a one-off manual lookup. There are eight of them, they aren't designed to be called programmatically, and they don't combine into one consistent total across a national configurator or dealer network.
RedBook “Cost to Own” and valuation data
A well-known Australian source for vehicle valuations and running-cost estimates. Strong for research and editorial context; the Vyro API is focused specifically on the statutory and dealer breakdown of an actual drive-away quote, ready to embed in a purchase flow.
DAPC driveaway calculator (by Gradient)
A recognised drive-away calculation tool in the Australian market. Vyro's difference is integration-first design: REST endpoints, batch quoting, concession logic, and a single layer that connects configurator, pricing, DMS, and ordering.
Building it yourself
Eight rate tables, multiple CTP structures, concession rules, and financial-year rollovers to maintain in perpetuity. Workable once, costly forever — one API removes the ongoing maintenance burden and the silent rollover failures.
Because pricing is part of the broader Vyro coordination layer, on-road costs connect directly into the rest of the journey — configurator to pricing to DMS to ordering — through one integration, rather than stitching a calculator into a flow it was never designed for.
