Run The Numbers

Estimate only. Eligibility conditions apply. Confirm with RevenueWA. This calculator uses RevenueWA and Landgate figures checked on 20 October 2026 and assumes a contract signed on or after 7 May 2026.

• General and concessional rates have applied since 1 July 2008. The concessional rate applies to a home that includes a house, that you will live in, valued up to $200,000. It does not apply to vacant land.
• First home owner rate for contracts on or after 7 May 2026: homes no duty up to $600,000, concessional rate to $800,000; vacant land no duty up to $450,000, concessional rate to $550,000. RevenueWA has applied these rates. Other sources say the change was still going through Parliament, so check before you rely on it.
• First Home Owner Grant: shown as “up to $10,000” for new homes, off-the-plan purchases and building a home, where the total value is $800,000 or less (transactions from 7 May 2026). Not available for established homes. You must also meet the residence and other conditions.
• Assumes property south of the 26th parallel; buyers further north may be eligible for higher first home buyer concessions.
• Off-the-plan concession for contracts signed between 12 March 2026 and 30 June 2028. The calculator conservatively applies the taper between $800,000 and $900,000 per $100 or part, and does not model home-and-land package deals.
• Foreign transfer duty is 7% of the foreign buyers’ share of the value (from 1 January 2019).
• Landgate fees from 1 July 2026, for a single title. The transfer fee is based on the purchase price; Landgate uses the higher of the price and the dutiable value. Settlement agent, bank and inspection costs are not included.
