Calculation Formula for Optimal Duration

Optimal Duration = (Average Decision Time × Conversion Rate) ÷ Urgency Factor

Key Variables

  • Average Decision Time: Median time between product view and purchase
  • Conversion Rate: Current site conversion percentage
  • Urgency Factor: Product complexity (1-5 scale)

Calculation Example

Sample Calculation:
Decision Time: 45 mins
Conversion Rate: 3%
Urgency Factor: 2

Optimal Duration = (45 × 0.03) ÷ 2 = 0.675 hours ≈ 40 minutes
