The Appointment Setting Waterfall
In outbound marketing, results strictly trace the waterfall of contact, engagement, and conversion drop-offs.
Booked = Outbound Volume * Connect Rate * Meeting Set Rate
Closed Won = Booked * Show Rate * Close Rate * Deal Size
How it’s used
You input your cold total outreach (SMS, cold emails, voicemails) and estimate the percentage drop-off rate at each critical stage: Connects, Books, Shows, and Closes.
Why it matters
It visually proves the compounding power of optimizing your follow-up sequence. By playing with the calculator, you can mathematically prove that improving your appointment show-up rate by just 5% (perhaps through an automated SMS reminder sequence) drastically increases bottom-line revenue—without spending an extra dime acquiring net-new leads at the top of the funnel.
