Business Calculators
Focused tools for Australian GST amounts and gross profit or margin, with the formula and exclusions kept visible.
Use the GST tool to separate GST-inclusive and GST-exclusive values. Use the gross-profit tool with revenue and cost of goods sold from the same period and GST basis; it does not calculate operating or net profit.
How to use these calculators well
- Keep GST, revenue, profit and cash flow as separate measures.
- Use revenue and direct costs from the same period and on the same GST basis.
- Reconcile calculator outputs with invoices and accounting records before lodgement.
