Short Definition
Operating Margin (%) is the percentage of revenue left after Cost of Sales (COGS) and all operating expenses (R&D, Sales & Marketing, G&A). Depreciation & Amortization (D&A) are included within those expenses under GAAP. It reflects profit from core operations, before interest and taxes.

Why it matters for Investors
Operating discipline: Reveals how well the company turns gross profit into operating profit.
Leverage signal: Improving margin as revenue grows = operating leverage.
Valuation anchor: Often used in Rule of 40 and quality screens alongside growth.

Formula
Practical considerations -
Keep it GAAP vs. Adjusted: If you exclude one-offs or stock comp, label it Adjusted Operating Income/Margin (non-GAAP) and reconcile.
D&A is inside operating: Depreciation & amortization in COGS/OpEx reduce Operating Income. (EBITDA adds them back.)
Exclude non-operating items: Interest income/expense, FX, and investment gains/losses belong below operating income.
Segment view: Track by product/segment/region to see where leverage comes from.
Watch mix & hiring: Price/mix, gross margin, and headcount growth drive operating margin.

Operating Income | $2,500,000 | 50.0 − 22.5 − 8.0 − 12.0 − 5.0 |
Operating Margin (%) | 5% | (2.5 ÷ 50.0) × 100 |
Notes:
Be consistent on what sits in Research and Development Expense/ Sales and Marketing Expense / General and Administrative Expense.
If you exclude unusual items or stock comp, mark Adjusted and show a bridge to GAAP.

FAQs
Operating Income vs EBIT?
EBIT often equals Operating Income, but some companies include non-operating items (like one-off gains). Always check policy.Operating Income vs EBITDA?
EBITDA = Operating Income + D&A (and sometimes other add-backs). It’s non-GAAP.Does stock-based comp affect Operating Margin?
Yes. SBC is recorded in COGS/OpEx under GAAP, so it reduces Operating Income. If you show “ex-SBC,” label it Adjusted (non-GAAP) and reconcile.Where do restructuring/impairments go?
Usually within operating results. If excluded, present Adjusted Operating Income and show a bridge to GAAP.What drives Operating Margin changes?
Price/mix, gross margin, hiring/OpEx growth, and productivity.Can Operating Margin be negative?
Yes—then it’s an operating loss (e.g., heavy R&D/S&M or weak gross margin).
