Marketing ROI Statistics

ROI Calculation Fundamentals
Basic ROI Formula
Standard ROI Calculation
ROI = (Revenue - Cost) ÷ Cost × 100
Example:
- Campaign Cost: $1,000
- Revenue Generated: $4,000
- ROI = ($4,000 - $1,000) ÷ $1,000 × 100 = 300%
- Return: $3 for every $1 spent
ROI Variations
| ROI Type | Formula | Best For | Use Case |
|---|---|---|---|
| Simple ROI | (Revenue - Cost) ÷ Cost | Quick calculations | Campaign comparisons |
| ROAS | Revenue ÷ Ad Spend | Advertising campaigns | Paid media optimization |
| Customer ROI | CLV ÷ Acquisition Cost | Long-term planning | Strategic decisions |
| Incremental ROI | Incremental Revenue ÷ Cost | Testing impact | A/B test results |
