Start with comparable inputs
Check the period, unit and formula before calculating. Income-statement figures describe a period; balance-sheet figures usually describe a reporting date. Business models and accounting policies also affect comparisons.
ACCA distinguishes profitability from liquidity. A higher number is not automatically better: first explain what the chosen ratio measures.
Worked margins with fictional figures
Suppose revenue is 200,000, cost of sales 130,000 and operating profit 20,000 currency units. Gross profit is 70,000, gross margin is 35% and operating margin is 10%.
If last year gross margin was 40%, it fell by five percentage points. Possible explanations include pricing, input costs or sales mix. The calculation alone cannot identify which explanation is correct.
Interpret liquidity rather than declaring safety
Assume current assets of 60,000 include inventory of 30,000, while current liabilities are 40,000. Current ratio is 1.5. Using the stated formula, quick ratio is (60,000−30,000)/40,000 = 0.75.
The gap highlights inventory within current assets. Investigate turnover, receivable collectability and liability maturity. A reporting-date ratio does not guarantee that cash will be available when bills fall due.
Write an evidence-led paragraph
Practise four sentences: state the ratio and change, propose a possible mechanism, identify evidence needed and state a limitation. Product-level margin data could help assess a sales-mix explanation.
Bring your own calculations and one uncertainty to a tutorial. This exercise is for academic learning, not an investment recommendation or a substitute for independently completing assessed analysis.
