What is net margin?

Net profit expressed as a percentage of revenue.

In plain English

Net margin is the share of every pound of revenue that survives all the way to the bottom. Ten per cent net margin means ten pence of each pound is profit.

It is the clearest single measure of how efficiently the whole business converts sales into earnings, which makes it the number to watch over years rather than months.

What to know

Net profit over revenue
Everything is included, so it captures both delivery efficiency and overhead discipline.
Growth can reduce it
Adding headcount, tools and premises ahead of revenue compresses net margin. Sometimes deliberate, often accidental.
Compare the trend, not the absolute
Sector norms vary enormously. Whether your own margin is improving or eroding is the useful signal.
Marketing sits inside it
Marketing is an overhead in this calculation, so spend has to earn its place by producing profitable revenue.

Why it matters

Net margin is the discipline number. It is where an accumulation of small unexamined costs shows up, and where the difference between a busy business and a profitable one becomes visible. It also drives valuation if you ever sell.

Common mistakes

×Adding overhead in anticipation of growth that has not arrived.
×Watching revenue monthly and margin annually.
×Cutting marketing first when margin tightens, then losing the pipeline.
×Comparing net margin against an unrelated industry.

FAQs

Why is my net margin falling while revenue grows?

Usually overheads growing faster than revenue, or growth concentrated in lower-margin work. Check margin by line of work.

Is a low net margin always bad?

Not necessarily. Deliberate reinvestment compresses margin. Unexamined cost growth is the problem.
