The Missed-Call Revenue Index

Every unanswered ring is the sound of money leaving.

A modeled U.S. estimate of the revenue home-service shops lose each year to unanswered phones, built on published Invoca and CallRail benchmarks, with the formula and every input shown. Free to reference and quote.

Methodology

The Index multiplies two published benchmarks against a shop's own call volume and job value, which are labeled assumptions the reader can adjust. Missed-call rates come from two call-analytics platforms that measure different customer bases, so we show both rather than average them.

Formula: annual_lost = calls per week × missed-call rate × phone conversion × revenue per booked job × 52
