Return on Equity


Paul needs to construct his profitability ratios. He has identified the following information from his statement of financial position and income statement:

  • Sales: $22,500
  • Gross Profit: $11,250
  • Net Profit: $2,140
  • Equity: $14,978

Applying the formulas above, calculate Paul’s ‘Gross Profit Margin’, ‘Net Profit Margin’, and ‘Return on Equity’.

Earlier on we identified that Paul wanted a return on his investment of 25%. Discuss whether you think Paul’s return on equity is acceptable, and if not what you would suggest to improve the ‘Return on Equity’ ratio.
