What Is Gross Margin?Definition, Formula, Examples
Gross margin is the percentage of revenue remaining after subtracting the direct cost of goods sold (COGS), expressed as a ratio. It measures how efficiently a business converts revenue into gross profit before accounting for operating expenses, overhead, and taxes. Gross margin is a fundamental indicator of pricing power and production efficiency, and it varies significantly across industries.
Understanding gross margin is essential for anyone evaluating the worth of a business, whether you are an owner preparing for an exit, a buyer conducting due diligence, or an advisor structuring a transaction.

How Gross Margin Is Used in Business Valuation
Gross margin serves as the first diagnostic metric buyers examine during due diligence because it reveals the fundamental economics of the business model. A declining gross margin over three years signals competitive pressure, supplier cost increases, or pricing erosion that the next owner will inherit. Conversely, expanding gross margins suggest the business is gaining pricing power or improving procurement efficiency, both of which support higher valuation multiples.
Business owners preparing for a sale can improve gross margin — and by extension their valuation — by renegotiating supplier contracts, adjusting pricing strategies, reducing waste or spoilage, and eliminating low-margin products or services that dilute overall profitability. Even a two to three percentage point improvement in gross margin, maintained for 12 to 18 months before listing, can meaningfully increase the SDE and EBITDA figures that drive the purchase price.
Industry-specific gross margin benchmarks also inform which valuation method is most appropriate. Businesses with high gross margins (above 50%) often support SDE or EBITDA multiples that generate valuations exceeding revenue-based estimates, while low-margin businesses (below 30%) may find that revenue multiples produce more favorable results because their bottom-line profitability is compressed by thin margins.

Frequently Asked Questions About Gross Margin
What is a good gross margin for a small business?
Good gross margins depend heavily on industry. Service businesses like consulting, accounting, and digital marketing typically achieve 50-80% gross margins because their COGS is primarily labor. Product-based businesses like retail stores and restaurants operate with 30-65% gross margins. Manufacturing companies usually fall between 25-45%. The benchmark that matters most is whether your margin exceeds the median for your specific industry, which signals pricing power and operational efficiency.
How does gross margin affect business valuation?
Higher gross margins generally support higher valuation multiples because they indicate the business retains more of each revenue dollar to cover operating expenses and generate profit. A business with 70% gross margins has more room to absorb cost increases, invest in growth, and weather economic downturns than one operating at 25%. Buyers view high gross margins as a sign of competitive advantage, whether through brand strength, proprietary products, or efficient operations.
What is the difference between gross margin and net margin?
Gross margin measures profitability after only direct costs (COGS), while net margin measures profitability after all expenses including operating costs, interest, and taxes. A business might have a 60% gross margin but only a 10% net margin because of high rent, payroll, marketing, and administrative expenses. Both metrics matter in valuation, but gross margin reveals the fundamental economics of the business model, while net margin shows overall operational efficiency.
