Profit & cash
Net margin
The bottom line, as a percentage of sales.
Net margin is what is left after absolutely everything: costs, interest, tax, one-offs. It is the number most people quote and the one most vulnerable to manipulation, because every judgement call in the accounts eventually lands here.
The formula
Net margin = Net income ÷ RevenueFigure
The divergence that precedes most disasters
Reported profit climbing while the cash it supposedly generated goes nowhere. Either customers are not paying, or the sales were never really made.
Why it matters
It is the honest summary of profitability, provided you have checked that the profit turned into cash.
The mistake everyone makes
Reading it in isolation. Always check it against operating cash flow.
