About this tool
Gross margin measures the percentage of revenue remaining after deducting the direct Cost of Goods Sold (COGS) required to deliver your software service to customers. For pure software companies, high gross margins—typically between 75% and 85%—are the foundational superpower of the SaaS business model, leaving substantial profit to fund product development and marketing. However, with the rise of third-party AI APIs (OpenAI, Anthropic), complex cloud infrastructure (AWS, Cloudflare), customer support staffing, and merchant payment fees, SaaS COGS can quickly inflate if left unmonitored. Accurately segregating COGS from operating expenses (OpEx) is crucial for accurate financial reporting and investor diligence. Use this calculator to determine your true gross margin.
How It Works
- 1Input your total monthly subscription revenue.
- 2Input direct hosting and cloud infrastructure costs (AWS, Cloudflare, database hosting).
- 3Input direct customer support payroll and tooling allocated to servicing active accounts.
- 4Input merchant payment processing fees (Stripe, Dodo Payments).
- 5Inspect your calculated gross profit in dollars, gross margin percentage, and total COGS breakdown.
Formula & Math
Transparent LogicGross Margin (%) = ((Total Revenue - Total COGS) / Total Revenue) × 100
Worked Practical Example
A SaaS generates $50,000/mo. COGS: $4,000 hosting, $3,000 customer support, $1,500 payment fees ($8,500 total).
Calculation / Steps
Gross Profit = $50,000 - $8,500 = $41,500. Margin = ($41,500 / $50,000) × 100 = 83.00%.
Expected Result
83.00% gross margin ($41,500 gross profit; $8,500 COGS).
Frequently Asked Questions
What should be categorized as COGS in SaaS?+
Direct cloud hosting, third-party API query costs, customer support agent salaries, merchant processing fees, and software used directly to deliver the product.
Are software engineers included in COGS?+
No. Core software engineers building new features belong in Research & Development (R&D) under Operating Expenses (OpEx). Only site reliability engineers (SRE) maintaining live uptime are occasionally allocated to COGS.
What is an acceptable gross margin for venture-backed SaaS?+
Target 80%+ for pure software. SaaS products with heavy third-party AI LLM API costs often operate between 65% and 75%.
