About Aussie Property & Crypto Calc

Founded by Mike Backman · Last updated: 19 July 2026

I built Aussie Property & Crypto Calc after years of being frustrated with the quality of Australian financial calculators online. Too many were out of date, hidden behind paywalls, or designed to funnel you toward a particular lender's products. I wanted a free, independent resource that everyday Australians could actually trust.

My name is Mike Backman, and I research and maintain every calculator and guide on this site. I have spent years navigating the Australian property market as both a home owner and investor, dealing firsthand with stamp duty calculations, CGT events, LMI premiums, mortgage refinancing, and the general maze of Australian tax law that comes with property and crypto investing.

Why I Built This Site

Australian financial calculations are surprisingly complex. Stamp duty rates differ between every state and territory. CGT depends on how long you've held an asset, your marginal tax rate, and whether any exemptions apply. LMI premiums vary by lender, deposit size, and loan type. Superannuation projections require understanding contribution caps, preservation ages, and the super guarantee rate.

I was tired of using calculators that gave different answers for the same inputs, hadn't been updated when rates changed, or buried the actual calculation behind a lead-capture form. So I built my own — and decided to make them free for everyone.

Our Methodology

Data Sources

All calculators are built using official government data:

Australian Taxation Office (ATO) — tax rates, CGT rules, superannuation caps, crypto tax guidance
ASIC MoneySmart — consumer finance guidance and benchmark calculations
Reserve Bank of Australia (RBA) — cash rate, interest rate data
State Revenue Offices — Revenue NSW, Revenue Victoria, Queensland Revenue Office, Revenue SA, Revenue WA, ACT Revenue Office, TAS Revenue, NT Revenue
APRA — superannuation statistics and benchmarks

Update Process

I monitor these sources regularly and update calculators as soon as rates or legislation change. Each page displays a "last updated" date so you can see how current the information is. When a budget announcement or legislative change affects calculations, I update the relevant pages and note what changed.

Calculator Testing

Every calculator is tested against worked examples published by the ATO, state revenue offices, and ASIC MoneySmart. If a government source provides a sample calculation, I verify my calculator produces the same result before publishing.

Editorial Policy

Independence. We are not affiliated with any bank, lender, real estate agency, or financial institution. Our calculators are not designed to funnel you toward any particular product or provider.
Accuracy first. All figures are based on current legislation and government-published rates. When in doubt, I link to the official source so you can verify.
Transparency. All calculations are estimates for general guidance only. I'm always clear about what assumptions are built in and what isn't covered.
Updates. Pages display a "last updated" date. I review all calculators at least quarterly and after any major legislative change.
Corrections. Found an error? Let me know — I read every message and fix issues promptly.
