About Calcroo

Calcroo builds free, accurate calculators for tax and pay questions Australians actually ask — updated for each financial year from day one, starting with FY 2026–27.

How we work

• Client-side by design: every calculation runs in your browser. Your income and financial details are never sent to our servers — we don't have servers that store them.
• Sources you can check: our rates and thresholds are based on figures published by the Australian Taxation Office (ato.gov.au) and are reviewed against official sources before each financial year.
• Plain answers: we show the full breakdown — tax, Medicare levy, HECS-HELP — not a single mystery number.

What we are not

Calcroo is an information tool, not a financial adviser, tax agent or credit provider. Our results are estimates for general information only. For advice on your personal situation, speak to a registered tax agent or licensed adviser.
