About This Calculator
Lead response time is the duration between when a prospect submits a form and when sales makes first contact. Research from Harvard Business Review (Oldroyd, McElheran, Elkington, 2011) shows companies responding within 5 minutes are 21x more likely to qualify leads, while the average B2B company takes 42 hours (InsideSales.com, 2017). This calculator quantifies how much revenue your company loses due to slow response times by applying a research-backed decay curve: effectiveness drops from 100% at under 5 minutes to just 3% after 24 hours. Enter your lead volume, deal size, and current response time to see the annual revenue at risk and the dollar value of responding faster.
