Sources applied

  • Formulas: gross profit = sales − direct cost; margin = gross profit / sales × 100; markup = gross profit / direct cost × 100.
  • Figures: supplied by you. No statutory rate or threshold is applied. Definitions follow business.gov.au: pricing.

How it works

Gross profit = sales − direct cost. Margin = gross profit / sales × 100. Markup = gross profit / direct cost × 100. Use a consistent GST basis and matching period. A zero denominator leaves that percentage undefined.
