Core concepts
Concept 1
Profitability ratios relate profit measures to revenue or capital employed to help users evaluate margin and return.
Exam cue: Write the required formula and use figures from the same period and basis.
Concept 2
Interpretation requires consistent formulas, comparable periods and investigation of business causes behind a change.
Exam cue: Describe the direction and size of change, then connect it to plausible revenue, cost or asset drivers.
Concept 3
Ratios summarise accounting information but do not by themselves explain cash flow, risk, accounting-policy differences or non-financial performance.
Exam cue: Use an appropriate comparator and state limitations before reaching a conclusion.
