What this dot point is asking
SCSA wants you to calculate each ratio, state its units, and interpret what a result means for the business rather than just reporting a number.
Profitability ratios
Gross profit margin isolates the markup on goods sold before operating costs. Net profit margin captures the effect of all expenses. Return on assets shows how efficiently the asset base generates profit, while return on equity shows the return to the owners specifically.
Efficiency ratios
A higher inventory turnover means stock sells quickly, freeing cash and reducing holding costs, though too high may signal lost sales from running out. A higher receivables turnover means customers pay faster. Turnover can be converted into days: 365 divided by the turnover gives the average days stock is held or the average collection period.
