Net profit margin

Answer: “How much profit are we generating for each dollar in sales?”

Operating profit margin

External comparisons can be informative within a sufficiently similar peer group. They require care because industry economics, business models, accounting policies and the definition of operating profit can differ.

Extracted signals

Strengths, limits, and pitfalls.

Net profit margin

  • Decompose the margin change and compare it with cash conversion, return on capital and reinvestment. A ratio becomes useful when its drivers are actionable.

Watch for

  • Do not treat an old cross industry league table as a benchmark. Accounting choices, one offs, business models and economic cycles can make apparently similar margins incomparable.

Operating profit margin

  • Create a margin bridge that separates price, volume, mix and cost effects. The percentage tells you what changed; the bridge helps explain why.

Watch for

  • Do not compare operating margins until you have reconciled the operating profit definitions. Two companies can label different subtotals “operating profit.”
