Understanding Gross Margin: The Critical Metric for SaaS Success

July 3, 2025

In the fast-paced world of SaaS, executives are constantly monitoring various financial metrics to gauge business health and inform strategic decisions. Among these metrics, gross margin stands out as particularly vital. While revenue growth often captures headlines, gross margin provides deeper insights into operational efficiency and long-term sustainability. This article explores what gross margin is, why it matters specifically for SaaS businesses, and how to measure and improve it.

What is Gross Margin?

Gross margin represents the percentage of revenue that exceeds the direct costs associated with producing your product or service. In its simplest form:

Gross Margin (%) = (Revenue - Cost of Goods Sold) / Revenue × 100

For SaaS companies, the formula remains the same, but understanding what constitutes "Cost of Goods Sold" (COGS) requires careful consideration. Typically, SaaS COGS includes:

  • Cloud infrastructure and hosting costs
  • Customer support personnel directly serving customers
  • Implementation and onboarding teams
  • Third-party software licenses included in your product
  • Data costs and API calls

Unlike traditional businesses, SaaS companies benefit from not having physical inventory or manufacturing costs. However, they must account for the technical infrastructure required to deliver their software solutions.

Why Gross Margin Matters for SaaS Companies

1. Indicator of Scalability

In the SaaS model, high gross margins (ideally 70-85%) suggest that incremental revenue significantly contributes to profitability. According to data from KeyBanc Capital Markets, top-performing SaaS companies maintain gross margins around 80%, allowing them to invest more aggressively in growth while maintaining healthier overall financial positions.

2. Valuation Impact

Investors and acquirers pay close attention to gross margins when valuing SaaS businesses. According to Bessemer Venture Partners' State of the Cloud report, a 10% difference in gross margin can translate to a 12-15% difference in valuation multiples among comparable companies.

3. Cash Efficiency

With higher gross margins, companies can achieve profitability with less capital. This becomes particularly important during economic downturns or when raising capital becomes challenging. According to OpenView Partners' SaaS Benchmarks report, companies with gross margins above 75% typically require 30-40% less funding to reach profitability compared to those with margins below 65%.

4. Strategic Flexibility

Strong gross margins provide executives with more options for strategic investments. Whether it's accelerating R&D, increasing sales and marketing spend, or weathering competitive pricing pressures, higher margins create strategic flexibility.

How to Measure Gross Margin Effectively

Measuring gross margin in SaaS requires careful accounting practices and a clear understanding of what costs are truly direct costs of service delivery.

Step 1: Calculate Revenue

For subscription businesses, this means recognizing revenue over the service period rather than at the point of sale. Be sure to account for:

  • Monthly recurring revenue (MRR)
  • Annual contracts (appropriately recognized)
  • Usage-based revenue components
  • Implementation or professional services revenue (which should be tracked separately)

Step 2: Calculate COGS

This is where many SaaS companies diverge in their approaches. To maintain consistency and comparability, follow these guidelines:

Include in COGS:

  • Cloud infrastructure costs (AWS, Azure, GCP)
  • Technical support team salaries and benefits
  • Third-party API costs that scale with usage
  • Customer success personnel directly involved in service delivery
  • Data hosting and processing costs

Exclude from COGS:

  • Sales and marketing expenses
  • General R&D costs
  • General and administrative expenses
  • Customer acquisition costs

Step 3: Track Trends Over Time

Gross margin should be monitored on a monthly, quarterly, and annual basis. According to analysis by SaaS Capital, gross margins often decrease slightly as companies scale beyond $10M ARR, primarily due to increasing complexity in service delivery. Tracking these trends allows executives to identify issues before they become significant problems.

Industry Benchmarks for SaaS Gross Margins

Understanding how your company compares to industry standards provides valuable context:

  • Elite SaaS Companies: 80-85%
  • Strong Performers: 70-80%
  • Average Performers: 65-70%
  • Concerning Territory: Below 65%

However, these benchmarks should be considered in context. Companies with significant professional services components or hardware elements may have structurally lower gross margins while maintaining healthy businesses.

Strategies to Improve Gross Margin

If your gross margins need improvement, consider these proven strategies:

1. Optimize Infrastructure Costs

Cloud costs often represent the largest component of COGS. According to Andreessen Horowitz research, companies can typically reduce cloud spending by 30-40% through:

  • Reserved instance commitments
  • Right-sizing infrastructure
  • Implementing auto-scaling
  • Optimizing storage tiers

2. Implement Tiered Pricing

Design pricing tiers that align customer value with resource consumption. Higher-value features that don't significantly increase your costs should command premium pricing, improving overall margins.

3. Automate Customer Support and Onboarding

By investing in self-service options, knowledge bases, and automated onboarding flows, you can maintain or improve customer satisfaction while reducing the personnel costs included in COGS.

4. Evaluate Build vs. Buy Decisions

Sometimes building in-house is more cost-effective in the long run than paying for third-party services that scale with your growth. This analysis should be revisited regularly as your scale changes.

5. Consider Pricing Adjustments

If your product delivers significant value but maintains lower-than-industry margins, you may be underpricing. According to a Price Intelligently study, most SaaS companies undercharge by 20-30% relative to the value they deliver.

Conclusion

Gross margin serves as a fundamental measure of the financial health and operational efficiency of SaaS businesses. While top-line revenue growth often captures attention, sustainable business models and strong valuations depend on maintaining healthy gross margins.

For SaaS executives, the goal shouldn't necessarily be maximizing gross margin at all costs, but rather optimizing it within the context of your specific business model and growth stage. By understanding, measuring, and strategically improving gross margin, SaaS leaders can build more resilient businesses capable of sustained growth and profitability.

By monitoring this critical metric and implementing the strategies outlined above, you'll be better positioned to make informed decisions about pricing, infrastructure investments, and overall business strategy in an increasingly competitive SaaS landscape.
