Why Calcroo?
Most Australian tax calculators are built by banks and lenders to funnel you toward their products, or they lag behind when rates change. Calcroo is different: we update on day one of every financial year (the 2026–27 rates went live from 1 July 2026), we show our working, and your numbers never leave your device — every calculation happens locally in your browser.
We're starting with the calculations Australians look up most — income tax, take-home pay and HECS-HELP — and adding new tools through 2026. Something you'd like us to build? Tell us.
