ROI Calculation Formula
Basic ROI Formula

- Customer Lifetime Value (CLV): Average revenue per customer × average customer lifespan
- Conversion Rate: Number of conversions / total visitors × 100
- Cost Per Click (CPC): Total ad spend / number of clicks
- Return on Ad Spend (ROAS): Revenue from ads / cost of ads
