Find your operating margin — operating profit as a percent of revenue — the cleanest read on how efficiently the core business runs.
Operating margin = (revenue − COGS − operating expenses) ÷ revenue. It excludes interest and taxes, so it isolates core operations. Compare within an industry — margins vary widely between, say, software and retail. General information only.
Operating margin strips out financing and taxes to show how much profit the core business makes from each dollar of sales, after both the direct cost of goods and the overhead of running the place. It's a cleaner efficiency signal than net margin because it's not distorted by debt or one-off tax items.
Operating margin = operating income ÷ revenue
Net margin subtracts interest and taxes too. Operating margin stops before them, so it reflects operations alone — useful for comparing businesses with different debt levels.
Very industry-dependent — software can run 20–40%, grocery a few percent. Track your own trend and benchmark against close competitors, not across sectors.
