Methodology

This scorecard models lead conversion decay based on research from InsideSales.com (now XANT), Drift, and the Harvard Business Review. The landmark MIT/InsideSales.com study of 1.25 million sales leads found that responding within 5 minutes makes you 21x more likely to qualify a lead than waiting 30 minutes. Drift’s Lead Response Report confirmed that only 7% of companies respond within 5 minutes, while the average B2B response time exceeds 42 hours. The decay brackets used here are conservative estimates derived from these studies, showing the relative conversion probability at each response time threshold compared to an instant (≤1 minute) response. The “optimal conversion” metric reverse-engineers what your booking rate would be if response time were not a limiting factor. Actual results vary by industry, lead source quality, and sales process. All calculations run client-side; no data is collected or transmitted.
