About BizMetrixs — Free Financial Tools Built for Australian Businesses
We built BizMetrixs because we were frustrated. Frustrated with financial calculators designed for the US or UK market that got Australian tax rates wrong. Frustrated with tools that locked basic features behind expensive subscriptions. Frustrated with spreadsheets that broke every time the ATO updated a threshold.
So we built our own — from scratch, for Australia. Our team of financial professionals and developers based in Sydney has spent years building tools that reflect how Australian businesses actually operate: with GST, with state-specific stamp duty, with the Medicare Levy Surcharge, with HECS-HELP debt, and with a superannuation system unlike anywhere else in the world.
Our commitment is simple: every calculator on BizMetrixs will always be free, always reflect current ATO rates, and always give you an instant result without requiring an account. We believe financial clarity shouldn't cost money.
“We believe every Australian business owner deserves access to accurate financial tools — not just those who can afford an accountant.”
— BizMetrixs Team, Sydney NSW
What Makes BizMetrixs Different
There are plenty of financial calculators online. Here's why Australian businesses choose ours.
Always ATO-Updated
When the ATO releases new rates, thresholds, or rules, we update every affected calculator. Usually within 48 hours of publication. You never calculate on last year's figures.
Genuinely Free
No freemium tricks. No tool gets locked behind a paywall. Ever. Every one of our 90+ calculators is free to use, forever. We fund the site through non-intrusive advertising.
Built for Australia
Not adapted from US or UK tools. Built from scratch for Australian tax law, state-specific property regulations, and the way Australian businesses actually work.
Private by Design
We never store your inputs or share your data with third parties. Every calculation happens in your browser. Your financial numbers stay on your screen.
