About calculatestampduty
A free, independent calculator for property and vehicle stamp duty in Australia.
calculatestampduty is built and maintained by LMG Pacific. It exists to answer one question quickly and correctly: what will this actually cost in duty, in my state?
Most of this category is either a bank calculator carrying megabytes of framework to render eight input fields, or a lead-generation page with a calculator as the bait. This site is neither. It is free, permanently, with no accounts, no email capture, and nothing sent to a server — the calculation runs entirely in your browser.
See our methodology for exactly how rates are sourced and verified, and our privacy page for what does and does not happen with your data.
