A calculator built for your business, free

For brokers, accountants, financial advisers and anyone else whose clients keep asking the same question.

We will build a calculator for your business at no charge. You describe the tool — a FIFO tax estimator, practice-owner super, salary packaging for doctors, commission-based borrowing power, or something else — and we add it to auscalcs.com.au, then give you a free embeddable version in your brand colour with a small “Powered by AUS/CALCS” link.

The public page stays ours, so the rates stay current the same day the rest of the site does. The embed is yours to put on your own site. There is no account, no fee and no contract. The only mark on the embed is that small backlink, sitting where your readers can see it.

Already happy with a calculator we publish? You can embed any of them today, in cream or white, with the same credit line. This page is for the one we have not built yet.

How it works

Step 1

Tell us what you need

The decision your client is trying to make, the inputs they have, and the numbers they want back. A sentence is enough to start. Detail helps us build the right thing.

Step 2

We build it and check it

We write the calculator and check the maths against the official source — the ATO, a state revenue office, APRA, the RBA or Services Australia, whichever actually publishes the rule.

Step 3

You get the embed

It goes live on AusCalcs. You receive a snippet in your brand colour, with a small “Powered by AUS/CALCS” link. When a rate changes, your copy changes with ours.

The sort of thing we mean

These are examples, not calculators that already exist. If one of them is yours, say so in the form. If yours is different, describe that instead.

FIFO tax estimator

For an accountant whose clients fly in and fly out. Zone tax offset, travel and the bits of a remote roster a standard income-tax form never asks about.

Practice-owner super

Contributions, caps and Division 293 for someone who owns a medical or professional practice, rather than a straight salary.

Salary packaging for doctors

A public-hospital package: what can be packaged, what fringe benefits tax does to the rest, and what lands in the pay. The general salary packaging calculator is the starting point, not the finished tool.

Commission-based borrowing power

For a broker whose clients are paid on commission, not a salary. The borrowing-power calculator assumes a steady income. This one would not.

Tell us what to build

We read every request. Sending one does not add you to a mailing list, and it does not oblige us to build it — see the questions below for how we choose.

So we can reply about this request. Nothing else.

Optional. The site the embed would live on.

Questions worth asking first

What does a custom calculator cost?
Nothing. We build it free, publish it on auscalcs.com.au free, and give you the embed free. There is no setup fee and no monthly fee.
Who owns the calculator?
The calculator lives on AUS/CALCS. We host it, we keep the rates current, and the page is ours. The embed is yours to use on your site, in your brand colour, for as long as you want it there.
Is the calculator financial advice?
No. It is general information only, the same standard as every other calculator on AusCalcs. It is not personal financial advice, and it is not a recommendation.
Will you build every request, and when?
We choose which requests to build, and we choose the timing. A clear brief that other Australians would use as well is the most likely to be built. We email you either way.
How is the maths checked?
Against the official source for that rule: the ATO, a state revenue office, APRA, the RBA or Services Australia, whichever publishes it. The page is dated when it is reviewed, the same as the rest of the site.
General information only. A calculator we build under this offer is an estimate from published rules, not financial, tax or credit advice. AusCalcs operates in accordance with ASIC Corporations (Generic Calculators) Instrument 2026/41. If you are an individual with an idea rather than a business wanting an embed, the public route is suggest a calculator.
