What is Gross Profit Margin?
Gross profit margin shows how efficiently a company produces and sells its products. It measures the percentage of revenue that exceeds the direct cost of goods sold, before operating expenses are considered.
What's a Good Gross Margin?
SaaS companies typically achieve 70-80% gross margins. Ecommerce ranges from 25-50%. Manufacturing often runs 25-35%. Higher margins indicate pricing power and operational efficiency.
How to Calculate Gross Profit Margin Step by Step
Step 1: Determine total revenue for the period.
- Revenue: $420,000 (monthly)
Step 2: Identify all COGS. Include only direct costs of producing/delivering your product. For SaaS: hosting, APIs, support, payment processing. For ecommerce: product cost, shipping, packaging, fulfillment.
SaaS example:
- Cloud infrastructure: $21,000
- Third-party APIs: $8,400
- Customer support: $25,000
- Payment processing (2.9%): $12,180
- Total COGS: $66,580
Step 3: Calculate gross profit and margin.
- Gross Profit = $420,000 - $66,580 = $353,420
- Gross Profit Margin = $353,420 ÷ $420,000 = 84.1%
Step 4: Compare to benchmarks for your business model.
- SaaS: 70-85% is healthy, 85%+ is excellent
- Ecommerce: 30-50% is typical, 50%+ is strong
- Marketplace: 60-70% on take rate
- Services-heavy SaaS: 50-65% (the services component drags it down)
Step 5: Identify what's dragging margin. Look at each COGS component as a percentage of revenue to find optimization opportunities. Customer support at 6% of revenue might signal you need better self-serve documentation.
Common mistakes founders make:
- Not including customer support in COGS (investors will add it back)
- Including R&D in COGS (it's an operating expense, not COGS)
- Mixing product lines without tracking margin per product (your core product might be 90% margin while a services add-on is 30%)
Improving Gross Margin
Increase prices, reduce direct costs, negotiate better supplier terms, improve production efficiency, or shift product mix toward higher-margin offerings. Use our pro forma income statement generator to project how margin improvements impact your bottom line.
Gross Profit = Revenue - Cost of Goods Sold (COGS)
Gross Profit Margin = (Gross Profit / Revenue) × 100
Ecommerce store performance:
- Revenue: $500,000
- Product Cost: $200,000
- Shipping Cost: $50,000
- Payment Processing: $15,000
COGS = $200K + $50K + $15K = $265,000
Gross Profit = $500K - $265K = $235,000
Gross Margin = $235K / $500K = 47%
