ROI Calculation

CRO Program ROI =
(Revenue Increase - Program Cost) / Program Cost × 100

Example:
Baseline: 100,000 visitors × 2% CR × $100 AOV = $200,000
Optimized: 100,000 visitors × 2.5% CR × $100 AOV = $250,000
Revenue Increase: $50,000
Program Cost: $10,000
ROI: ($50,000 - $10,000) / $10,000 × 100 = 400%
