Sources and methodology

Where the numbers come from.

Every default in this calculator traces to tracked audit data or published research. Nothing is invented to make the number bigger.

SummitMark Denver Audit

57% drop rate based on real inquiry submissions to 35 Denver PI firms. Every response tracked from submission to silence. Published at thesummitmark.com.

Harvard Business Review

Firms that contact leads within 5 minutes are 9x more likely to convert them. Most businesses take hours or days to follow up after initial response.

Industry benchmarks

Drop rates by industry estimated from published research by ServiceTitan, NAR, and dental/medical practice management studies. Adjustable to match your business.

Calculation

Annual leads x drop rate x close rate x deal value = estimated recoverable revenue. This is not a guarantee. It is a directional estimate based on the best available data.
