Worked example 1
Revenue $500,000; gross profit $150,000; net profit $40,000; PBIT $55,000; capital employed $400,000; current assets $90,000 (inventory $30,000); current liabilities $60,000. Calculate GP margin, ROCE, current ratio, and acid test.
Show solution outline
GP margin = ($150,000 ÷ $500,000) × 100 = 30%
ROCE = ($55,000 ÷ $400,000) × 100 = 13.75%
Current ratio = $90,000 ÷ $60,000 = 1.5 : 1
Acid test = ($90,000 − $30,000) ÷ $60,000 = 1.0 : 1
Interpretation: Healthy GP margin; ROCE acceptable if cost of capital is lower; liquidity is adequate but the acid test is at the minimum benchmark, suggesting a reliance on selling inventory to meet short-term debts.
