Financial Calculators
Eighteen calculators, written for Australian rules — 2026–27 tax rates, the 12% super guarantee, the $32,500 concessional cap and Centrelink’s income and assets tests. Every one runs in your browser.
What is inside
Rates and thresholds checked against the ATO and Services Australia for FY2026–27.

Know what you have
The unglamorous foundation. Before any investment decision, you need to know what your household generates each month and what your balance sheet actually looks like.
Know what debt costs
Australian mortgages and loans are long-dated, and compounding works in both directions. These tools show the repayment, the total interest, and the structure that gets you out early.
Know what you are owed
Super is 12% of your pay and, for most people, the largest asset they will ever hold outside the family home. Check it, project it, and use the caps properly.
Know when you can stop
The shift from accumulating to drawing down is where most plans quietly fail. Model the income, not just the balance.
Know what it really returns
Fees, tax and inflation decide the outcome far more than fund selection. These three make the drag visible.
Know what you keep
2026–27 rates, including the 15% bracket that started on 1 July 2026. Most calculators online still run the 2024–25 tables.
About these calculators
Are these calculators free?
Yes, entirely. There is no account, no email capture and no limit on use. They run in your browser, so nothing you type is sent to us or stored anywhere.
Which financial year do they use?
2026–27, from 1 July 2026 to 30 June 2027. That includes the 15% rate on income between $18,200 and $45,000, the 12% super guarantee, the $32,500 concessional contributions cap, the $130,000 non-concessional cap and Age Pension rates from 20 September 2026.
How accurate are the results?
They are arithmetically exact against the assumptions you enter, and the tax and super rules are current. What they cannot do is predict investment returns, and none of them account for your full circumstances. Treat the output as a well-informed estimate rather than a quote.
Can I use them on my phone?
Yes. Every calculator is built mobile-first: full-width inputs at 52 pixels high, no horizontal scrolling, and the result panel moves to the top of the screen on a phone so you can see the number change as you type.
What is not covered?
Stamp duty by state, salary packaging, insurance needs and aged care means testing are the most requested additions. They are not built yet. If one of those would help, tell us and it moves up the list.
Should I act on the result?
Only as a starting point. A calculator cannot see your tax position, your trust structures, your risk tolerance or your goals. If a number here changes what you are about to do, it is worth thirty minutes with an adviser before you do it.
Want these numbers run properly?
A calculator answers a question you already know how to ask. Most of the value in advice is finding the question you have not thought of — the structure, the sequencing, the timing.
General advice only · No obligation · No product push
These calculators provide general information only. They do not take into account your objectives, financial situation or needs, and they are not personal financial product advice, tax advice or a credit quote. Assumptions are stated on each page; returns are not guaranteed and past performance is not a reliable indicator of future performance. Tax and social security rules change. Before acting on anything here, consider your own circumstances or speak to a qualified adviser, and confirm tax matters with a registered tax agent. Dominium Capital is a corporate authorised representative providing general advice only.
