Gross Margin

Why Gross Margin Matters

Gross margin determines how much money you have to run and grow the business. A company with 80% gross margin keeps $0.80 of every dollar for operations. A company with 50% gross margin only keeps $0.50.

High gross margins are a defining characteristic of great software businesses. They enable aggressive investment in growth while still generating profit. Low margins force difficult trade-offs.

How to Calculate Gross Margin Step by Step

Step 1: Calculate your total revenue for the period. Pull revenue from your billing system or accounting software. Use a monthly or quarterly period. Include only recognized revenue — not bookings or deferred revenue.

• Total revenue (last quarter): $375,000

Step 2: Identify your Cost of Goods Sold (COGS). For SaaS, COGS includes the direct costs of delivering your product. This is where most founders struggle — you need to categorize expenses correctly.

Include in SaaS COGS:

• Cloud infrastructure (AWS, GCP, Azure): $18,000
• Third-party API costs (Twilio, SendGrid, data providers): $9,500
• Customer support team salaries: $27,000
• DevOps/infrastructure team salaries (portion): $15,000
• Payment processing fees (Stripe's 2.9%): $10,875
• Third-party software embedded in your product: $4,500
• Total COGS: $84,875

Do NOT include in COGS:

• R&D / engineering salaries (that's operating expense)
• Sales and marketing (operating expense)
• General and administrative (operating expense)
• Office rent, legal, accounting (operating expense)

Step 3: Calculate Gross Profit and Gross Margin.

• Gross Profit = $375,000 - $84,875 = $290,125
• Gross Margin = $290,125 ÷ $375,000 = 77.4%

Step 4: Benchmark your result.

• 80%+ gross margin: Excellent — typical of well-run SaaS
• 70-80%: Good — check if you can optimize infrastructure costs
• 60-70%: Below average — likely have a heavy services component or infrastructure bloat
• Below 60%: Concerning for SaaS — may indicate a services business disguised as software

Step 5: Track the trend and find the levers. Gross margin should improve as you scale because infrastructure costs typically grow slower than revenue. If margin is declining, investigate:

• Are hosting costs scaling linearly with users? (Consider architecture optimization)
• Is customer support scaling with headcount instead of automation?
• Are third-party API costs eating into margin? (Consider building in-house)

Common mistakes founders make:

• Excluding customer support from COGS (investors will add it back)
• Including R&D salaries in COGS (overstates cost, understates margin)
• Not including payment processing fees (Stripe's 2.9% adds up fast)
• Reporting gross margin without separating one-time revenue (services revenue has different margins)
• Not tracking gross margin by product line or customer segment

Skip the spreadsheet. Futureproof categorizes your expenses automatically and calculates gross margin in real-time — properly separating COGS from operating expenses so your numbers match what investors expect.

Gross Margin Benchmarks

SaaS companies typically achieve 70-85% gross margins. Below 70% suggests infrastructure inefficiency or heavy services component. Above 85% is excellent. Ecommerce margins are much lower, typically 30-50%.
