Gross Margin
Gross margin is revenue minus Cost of Goods Sold (COGS) divided by revenue, expressed as a percentage. For SaaS companies, COGS includes hosting, infrastructure, customer support, and professional services costs directly tied to delivering the product. A 75% gross margin means $0.75 of every revenue dollar is available for sales, marketing, R&D, and profit.
Why Gross Margin Matters for SaaS Companies
Gross margin is the multiplier underneath every other SaaS metric. LTV calculations use gross margin, not revenue. Payback period uses gross margin. The Rule of 40 depends on it. A 10-point improvement in gross margin ripples through every metric in your financial model. Investors expect SaaS gross margins above 70% — below that raises questions about whether you are truly a software business.
Formula
Gross Margin = (Revenue - COGS) / Revenue x 100%
Benchmark
Best-in-class SaaS: 80%+. Good: 70-80%. Below 70%: investigate COGS structure.
Tools for Measurement
An Operator's Take
Most founders calculate gross margin correctly for their board deck but do not manage it actively. At one engagement, gross margins were 65% — below the SaaS benchmark. The problem was not infrastructure costs — it was that customer onboarding required 15 hours of manual work per account. We built automated onboarding workflows that cut that to 3 hours. Gross margin went from 65% to 78%. That single change improved LTV by 20% and shortened payback period by 3 months without changing pricing or acquisition.

Common Mistakes
What I see go wrong most often in the field.
Not including customer support costs in COGS. Support headcount directly tied to delivering the product is a cost of goods sold.
Excluding hosting and infrastructure costs because they seem small. At scale, cloud costs can significantly impact margins.
Including R&D and sales costs in COGS. These are operating expenses, not cost of goods sold.

Frequently Asked Questions
What is a good gross margin for SaaS?
SaaS companies should target 70%+ gross margins. Best-in-class companies achieve 80-85%. Below 70% raises investor concern about whether the business model is truly software (vs. services-heavy). Infrastructure-heavy products (video, data processing) may have lower margins, which is understood but should be offset by higher ARPA.
What is included in SaaS COGS?
SaaS COGS typically includes: cloud hosting and infrastructure, customer support team costs, onboarding and implementation costs, third-party software directly used to deliver the product, and payment processing fees. R&D, sales, marketing, and G&A are operating expenses, not COGS.
