Tallyroo started with a simple frustration: Australian property costs are decided by published, public schedules — yet many calculators online are unsourced, or hide how they reach a number. When we tested competitors in September 2026, two of the calculators we opened were still charging NSW transfer duty on the brackets NSW had replaced when it re-indexed them on 1 July 2026.
So Tallyroo does it differently: every rate the law sets is taken from the official source, dated, and linked; where no official figure exists, as with LMI premiums or your own loan rate, the page says so and labels the estimate or asks for your number; and every page explains the brackets and concessions behind your result — the working, not just the answer.
Tallyroo is independent. It isn't owned by a bank, a broker or a real-estate portal, and it doesn't sell leads. The site is free to use and will be supported by advertising — ads are not running yet — which will never influence a calculation.
Who is behind Tallyroo
Tallyroo is run by Rakesh Choudhary. This isn't his first calculator platform: he also runs Indian Pay Calculator, a salary and pension platform relied on by Indian government employees, and Calcinum, a library of 130-plus US tax and finance tools — each built the same way: official schedules in, transparent working out, figures re-verified whenever the rules change.

Tallyroo publishes arithmetic, not advice, and the process behind it is the same on every page, as the methodology page sets out step by step. Each legislated figure is traced to its official source and dated. The duty and tax engines are pinned to official published figures — a revenue office’s own worked examples where it publishes them, its schedule where it does not, and the ATO’s worked examples for tax. The build fails rather than publish when a rate file still names last year two months after the year turns over, or carries no verification date. Pages are reviewed again, claim by claim against their sources, in a separate pass after they are built. And what turns out to be wrong goes in the public corrections log, with what the page said before. The rules behind all of this, from sources to advertising, are written down in the editorial standards. The authority here is the sources and the maths, and both are shown on every page. Whether those numbers suit your circumstances is a question for a conveyancer or a licensed adviser.
Who operates Tallyroo
Tallyroo is operated in Australia by Deepanshu Chaudhary, who holds the domain licence and looks after the Australian side of running the site. You can verify his profile on LinkedIn. He has no editorial role: he does not set, check or approve any figure, page or calculator on the site.
