What is a good operating margin for a SaaS company?

For mature companies: 15-25% is excellent, 10-15% is good, 5-10% needs improvement. Growth-stage companies often have negative margins as they invest in growth - evaluate alongside growth rate (Rule of 40).

How is operating margin different from gross margin?

Gross margin only subtracts COGS. Operating margin subtracts ALL operating expenses including R&D, sales & marketing, and G&A. Operating margin is a broader measure of business profitability.

What is the difference between operating margin and EBITDA margin?

Operating margin uses operating income (GAAP). EBITDA margin adds back depreciation and amortization. EBITDA margin is typically 2-5 percentage points higher than operating margin for SaaS companies.

How does operating margin vary by company stage?

Early-stage: -20% to -50% (investing in product and GTM). Growth stage: -10% to +10%. Mature: +10% to +25%. The Rule of 40 provides context - high growth justifies negative margins.

How do I improve operating margin?

Increase revenue (pricing, expansion), reduce R&D costs (product efficiency), optimize S&M spend (channel efficiency), or reduce G&A (automation, outsourcing). Each lever has different impact and timing.

What costs are excluded from operating margin?

Interest expense, interest income, tax expense, and one-time items (restructuring, acquisition costs, legal settlements). These are non-operating items below the operating income line.

How does operating margin affect valuation?

Higher operating margins command higher revenue multiples. Public SaaS companies with 20%+ margins trade at 8-12x revenue, while those with negative margins trade at 3-6x revenue.

How often should I track operating margin?

Monthly for internal management. Quarterly for board reporting and investor updates. Track the trailing 12-month trend to identify whether profitability is improving or degrading.
