Why SmartCalc

Most calculator sites are built for a global audience and treated as an afterthought under a wall of ads. SmartCalc is built specifically around Australian rules: current GST, tax, super, employment, and property settings, and kept fast and simple on purpose. Every calculator updates live as you type; nothing here waits on a "Calculate" button.

17 tools, one set of Australian rules

Tax and pay: GST, income tax and Medicare levy, Super Guarantee, HECS-HELP repayment, and pay & overtime. Super: a balance projection calculator, Division 293, and the First Home Super Saver Scheme. Employment: novated lease and car FBT, the Medicare levy surcharge, redundancy pay under the NES, ETP tax treatment on a termination payout, and leave/notice/LSL entitlements. Property: stamp duty and land tax across all 8 states and territories, capital gains tax, and rental yield with negative gearing. Each tool links through to the reference pages and FAQ you'd actually want next: the numbers behind each calculator, not just the calculator itself.
