How much are missed calls costing your business?
Move the sliders to match your business. Everything is calculated on this page — nothing is stored or sent.
Calls missed while busy, after hours or on weekends.
Your best estimate — a conservative guess is fine.
Estimated revenue at risk
An AI receptionist answers every call 24/7, answers common questions and books appointments — so fewer of these customers go to a competitor.
Estimate only, based on the numbers you entered. Monthly figures use 4.33 weeks per month.
How the calculation works
Missed calls per month = weekly calls × share missed × 4.33 weeks. Potential lost customers = missed calls × the share who would have become customers. Revenue at risk = lost customers × your average customer value. All figures are estimates based on the numbers you enter.
