# What Is Operating Margin?

> Operating margin is operating income divided by revenue — showing what percentage of sales remains after cost of goods sold and operating expenses, before interest and taxes.

**Operating margin** measures profitability from core operations as a percentage of revenue — a key lens on business quality at scale.

### How it works

Formula: Operating income ÷ Revenue. Operating income sits after COGS and OpEx (R&D, S&M, G&A) but before interest, taxes, and one-time items. Example: $50M revenue, $35M OpEx, $5M COGS → $10M operating income → 20% operating margin.

Early-stage startups often run **negative** operating margins intentionally while investing in growth. Investors expect margin improvement in later stages — best B2B SaaS targets long-term operating margins of 20–30%+ at scale, though paths vary by go-to-market motion.

**Gross margin** and operating margin tell different stories: high gross margin with negative operating margin suggests heavy S&M or R&D — common in land-grab phases.

### Why it matters

- **Founders:** Use margin bridges in board decks — price, COGS efficiency, headcount per revenue dollar — to show progress toward sustainable economics.
- **Investors:** Public comps and late-stage private rounds price partly on margin profile. Low gross margin caps ultimate operating margin regardless of OpEx discipline.

### Common mistake

Quoting EBITDA margin interchangeably with operating margin. EBITDA adds back depreciation and amortization — material for asset-heavy businesses, less so for pure SaaS.

## FAQ

### What is Operating Margin in simple terms?

### Why does Operating Margin matter?

For founders, improving operating margin shows leverage as revenue scales. For investors, margin trajectory distinguishes durable software economics from services-heavy or subsidy-driven growth that may never reach profitable scale.
