Understanding the Calculation:

Our calculator estimates your potential conversion and revenue loss based on common industry benchmarks and your website's performance metrics. Here's the logic:

  • Monthly Website Visitors (V): Your site's total monthly traffic.
  • Initial Conversion Rate (ICR): Your current conversion percentage.
  • Additional Page Load Time (LT): The extra seconds your page takes to load.
  • Estimated Conversion Drop per Second (CDPS): The average percentage point drop in conversion for each additional second of latency (defaulting to 0.07%).
  • Average Order Value (AOV): The average value of a single conversion.

Formula Steps:

  1. New Conversion Rate (NCR): NCR = ICR - (LT × CDPS)
  2. Lost Conversion Rate Percentage: Lost CR % = ICR - NCR
  3. Lost Conversions: Lost Conversions = V × (Lost CR % / 100)
  4. Lost Revenue: Lost Revenue = Lost Conversions × AOV
