What Is Gross Margin?
Gross margin is revenue minus cost of goods sold, expressed as a percentage. SaaS gross margins of 70-85% are the benchmark — they fund sales, marketing, and R&D growth.
Definition
Gross margin = (Revenue - Cost of Goods Sold) / Revenue × 100. For SaaS companies, COGS includes cloud hosting, infrastructure, third-party software licenses, and customer support costs. Everything else (sales, marketing, R&D, G&A) is operating expense, below the gross profit line.
SaaS gross margins are high compared to physical product businesses because the marginal cost of serving one more customer is very low — you don't ship a physical product or increase manufacturing costs. Well-run SaaS companies achieve 70-85% gross margins; elite companies exceed 80%.
Gross margin matters for SaaS valuation because it determines how much of revenue is available to fund growth and profitability. A 70% gross margin SaaS company keeps $70 of every $100 in revenue after delivering the service. A manufacturing company might keep $30 of $100.
Real-World Example
A SaaS company has $1M monthly revenue and $200K in COGS (AWS, support, third-party APIs). Gross profit = $800K. Gross margin = 80%. This $800K funds $500K in sales/marketing, $200K in R&D, and $100K in G&A, leaving zero operating profit but aggressive growth investment.
Why It Matters
Gross margin determines the economic engine of the business — how much fuel is available for growth spending. Low gross margins in SaaS often signal underlying architectural problems (high infrastructure costs, heavy services dependency) that limit long-term profitability.

Frequently Asked Questions
What is a good gross margin for SaaS?
70-80% is good; 80-85% is excellent; below 60% is a concern. Companies below 60% often have high service delivery costs, suggesting the product requires significant customization or human support to deliver value — a risk to scalability.
Why does SaaS have such high gross margins?
The software itself is replicated at near-zero cost — writing one more user doesn't require manufacturing, raw materials, or physical logistics. Infrastructure costs (AWS) are real but scale efficiently. The business model's elegance is that every incremental customer added at high gross margin dramatically improves unit economics.
How does gross margin differ from net margin?
Gross margin is revenue minus COGS — the cost of delivering the product. Net margin is after all operating expenses including sales, marketing, R&D, and G&A. A company can have 80% gross margin but -50% net margin (spending heavily on sales and R&D for growth). Most high-growth SaaS companies are gross-margin healthy but net-margin negative.
