How do I calculate the actual Return on Investment (ROI) for my discount campaigns? Does the tool help with this?

I'm struggling to understand the true financial impact of my e-commerce discount campaigns. While I can see sales numbers, I'm unsure how to accurately calculate the Return on Investment (ROI) and determine whether my discounts are genuinely profitable or just eroding my margins. I need a systematic approach to measure the financial effectiveness of my promotions, accounting for the discount costs, incremental sales, and potential long-term customer value. What metrics should I track, and how can I ensure my discount strategies are actually driving meaningful business growth?

Detailed ROI Calculation Steps

1. Gather Baseline Metrics

  • Average order value before discount
  • Conversion rate pre-campaign
  • Standard profit margins

2. Campaign Performance Calculation

ROI Formula: [(Campaign Revenue - Campaign Cost) / Campaign Cost] × 100%

Example Calculation:
Campaign Revenue: $15,000
Discount Cost: $3,000
Additional Marketing Spend: $1,000
ROI = [($15,000 - $4,000) / $4,000] × 100% = 275%

3. Advanced ROI Considerations

  • Customer Lifetime Value (CLV) impact
  • New customer acquisition cost
  • Repeat purchase probability
