Lead Leakage Calculator — comparison details

Read the example.

100 inquiries with 25% missed gives 25 missed inquiries. Recovering 40% yields 10, of which 60% qualify and 25% close: 1.5 expected sales and $300 contribution. After $200 additional effort cost, modeled net recovery contribution is $100.

The method

Missed inquiries = incoming × missed rate. Recovered = missed × recovery rate. Expected sales = recovered × qualification rate × close rate. Expected incremental contribution = expected sales × contribution/sale. Net modeled recovery contribution = expected contribution − added recovery effort cost.

Assumptions and limits

  • Fractional expected sales are averages across repeated situations, not a promise of fractional or actual sales.
  • Recovery, qualification and closing are separate conditional rates. Use one period and consistent inquiry definitions; avoid double-counting.
  • A missed inquiry is not automatically a lost customer. Recovery may overlap with customers who would have returned anyway.
  • Use aggregate figures only. This tool does not read call logs, contact customers or establish causal lift. Fixed overhead and unentered costs are excluded.
