Missed-Call ROI Calculator

Free tool that estimates the annual revenue your service business is losing to missed phone calls. Adjust five inputs — calls missed per week, average ticket, conversion rate if answered, after-hours premium, and lifetime value multiplier — to see the dollar impact in real time.

How the calculation works

Annual revenue lost = calls missed per week × 52 × conversion-if-answered rate × average ticket × (1 + after-hours premium) × lifetime value multiplier. Defaults reflect 2026 industry averages from our survey of 1,000 service-business customers.

Why this matters

62% of callers hang up after 2 rings. Only 9% leave voicemail; 71% call your competitor instead. The cost of a missed call is rarely just the lost ticket — it's the lifetime value of the customer plus the 18% premium people will pay for a business that actually answers.
