Worked Example
Checkout Conversion Funnel (85 Conversions / 2,500 Visitors)
An ecommerce checkout page records 2,500 unique visitors during a campaign, resulting in 85 completed customer orders.
- Conversions
- 85 orders
- Total Visitors
- 2,500 visitors
- Conversion Rate
- 3.40%
- Drop-Off Rate
- 96.60%
- Lost Visitors
- 2,415 visitors
- Conversion Rate = (85 ÷ 2,500) × 100 = 3.40%
- Drop-Off Rate = 100% - 3.40% = 96.60%
- Lost Visitors = 2,500 - 85 = 2,415 visitors
Takeaway: The checkout page achieved a 3.40% conversion rate with 85 converted customers and 2,415 dropped visitors.
