LEARN · FUNDAMENTALS

Gross margin

Gross margin is gross profit divided by revenue — roughly how much is left after direct costs of goods or services before operating expenses.

Open in Terminal ↗All terms →

Why it matters

Margin trends help separate pricing/mix/cost stories from pure top-line growth. Cross-company comparisons need similar business models.

How RomeWay uses it

When XBRL facts expose revenue and cost of revenue (or gross profit), stock pages can show margin history with period end dates. Missing taxonomy tags stay —.

FAQ

Is gross margin the same as operating margin?
No. Operating margin subtracts operating expenses (R&D, SG&A, etc.) after gross profit.
