Profit Margins Explained
Three Types of Profit Margins
- Gross Profit Margin: (Revenue - COGS) / Revenue × 100
- Operating Margin: Operating Income / Revenue × 100
- Net Profit Margin: Net Income / Revenue × 100
Real Example: E-commerce Business
Monthly Financials:
- Revenue: $100,000
- Cost of Goods Sold: $60,000
- Operating Expenses: $25,000
- Taxes & Interest: $3,000
Calculations:
- Gross Margin: ($100,000 - $60,000) / $100,000 × 100 = 40%
- Operating Margin: ($100,000 - $60,000 - $25,000) / $100,000 × 100 = 15%
- Net Margin: ($100,000 - $60,000 - $25,000 - $3,000) / $100,000 × 100 = 12%

Net Promoter Score (NPS) Calculation
Survey Results (100 responses):
- Promoters (9-10 rating): 45 people = 45%
- Passives (7-8 rating): 35 people = 35%
- Detractors (0-6 rating): 20 people = 20%
NPS = % Promoters - % Detractors = 45% - 20% = 25
Industry benchmarks: Tech/SaaS: 30-40, Retail: 20-30, B2B: 25-35

Interpreting Business Percentages
Context is Everything
⚡ Key Interpretation Principles
- Industry Context: A 5% net margin is excellent in retail but poor in software
- Trend Analysis: Direction matters more than absolute values
- Seasonality: Compare to same period last year, not last month
- Size Matters: 100% growth from $1K to $2K ≠ $1M to $2M
- Leading vs Lagging: Some metrics predict future, others report past
Red Flags in Percentage Metrics
- Declining Gross Margins: Rising costs or pricing pressure
- Increasing CAC: Marketing efficiency dropping
- Rising Churn Rate: Customer satisfaction issues
- Falling Conversion Rates: Product-market fit problems
- Decreasing Retention: Competitive threats or quality issues
Best Practices for Business Analytics
Creating Effective Dashboards
Dashboard Design Principles
- Hierarchy: Most important metrics at top/largest
- Comparison: Show actual vs target, current vs previous
- Color Coding: Green = good, red = attention needed
- Time Frames: Include daily, monthly, yearly views
- Drill-Down: Allow exploration of underlying data
Common Analytics Mistakes to Avoid
- Vanity Metrics: Focus on actionable metrics, not just impressive numbers
- Cherry-Picking: Don't select only favorable time periods
- Ignoring Cohorts: Different customer groups behave differently
- Over-Aggregation: Averages can hide important variations
- Short-Term Focus: Balance immediate results with long-term trends
