Gross Margin

What Is Gross Margin?

Gross margin is the percentage of revenue that remains after subtracting the Cost of Goods Sold (COGS) — the direct costs of producing and delivering your product or service. It represents the profit available to cover all other business expenses and ultimately generate net profit.

Gross Margin % = (Revenue − COGS) ÷ Revenue × 100

For example: Revenue = $500,000, COGS = $150,000. Gross Margin = ($500,000 − $150,000) / $500,000 = 70%.

Gross margin is not net profit — it does not account for sales, marketing, R&D, or administrative costs. It measures the efficiency of your core production and delivery process.

What Counts as COGS

COGS includes only costs directly attributable to producing and delivering each unit of value. For a software company this typically includes:

• Cloud infrastructure and hosting
• Third-party API and data costs embedded in the product
• Payment processing fees
• Customer onboarding costs (if directly tied to each new customer)
• Customer support costs directly tied to serving individual customers

COGS does not include: sales team salaries, marketing spend, R&D, general and administrative costs, or executive salaries. These are Operating Expenses (OpEx), not COGS.

Gross Margin by Industry

Gross margin benchmarks vary significantly across business models:

• Pure SaaS: 70–85% gross margins are typical; world-class companies target 75–80%+
• Marketplace platforms: 50–70% depending on take rate and operational costs
• E-commerce: 20–40% depending on category and fulfilment model
• Hardware + software: 30–50% at scale; lower at early stage due to unit volume
• Professional services: 25–50% depending on labour costs and utilisation
• Fintech (lending): Gross margin calculations differ, often using Net Interest Margin instead

Investors use these benchmarks to assess whether your business model is fundamentally competitive. A SaaS business with 40% gross margins will face hard questions about why costs are so high relative to software peers.

Why Gross Margin Matters for Startups

Gross margin determines the ceiling of your business. No matter how efficiently you manage overhead, you cannot achieve operating profitability if gross margin is insufficient to cover operating expenses.

For a startup with 70% gross margin, every additional $1 of revenue contributes $0.70 toward covering sales, marketing, and R&D. For a startup with 30% gross margin, the same $1 contributes only $0.30. The gross margin gap compounds dramatically at scale.

For LTV calculation, gross margin is the correct multiplier — not revenue. A customer generating $100/month at 70% gross margin has a gross profit contribution of $70/month; the same customer at 30% gross margin contributes only $30/month. LTV differs by 2.3x.

Improving Gross Margin Over Time

Most startups see gross margin improve as they scale due to:

Infrastructure efficiency: Cloud costs often decrease as volume grows and as teams negotiate better pricing or optimise infrastructure.

Reduced per-unit support costs: As the product matures and documentation improves, support costs per customer decrease.

Pricing power: Brands with strong product-market fit can raise prices over time without proportionally increasing COGS.

Mix shift: As the business grows, the mix may shift toward higher-margin products, customers, or channels.

For investors, improving gross margin over time is a healthy signal. Declining gross margin — particularly in a growing business — often signals either competitive pricing pressure or rising infrastructure/support costs that haven't been addressed.

Gross Margin vs Contribution Margin

Contribution margin is a related concept that includes variable sales and marketing costs in the calculation. It provides a closer approximation of true customer-level profitability. Some founders use contribution margin per customer as a more comprehensive view of unit economics than gross margin alone.
