How many hours is your business phone uncovered?
A normal work schedule covers only part of a 168-hour week. Enter the days and hours your team answers live, then add your actual after-hours call volume to estimate the gap and the monthly answering minutes needed to cover it.
Estimate your weekly coverage gap
Start with a schedule preset, then replace the call assumptions with numbers from your phone records.
At the entered volume, that is about 43.3 after-hours calls per month. Formula: open days × staffed hours, subtracted from 168 weekly hours; calls/week × 4.33 × average call length. This estimates schedule coverage and voice usage, not staffing cost or guaranteed demand.
Common questions
Use the result with the right context
How does the after-hours coverage estimator work?
It multiplies open days by staffed hours per day, then subtracts that result from the 168 hours in a seven-day week. The call-minute estimate multiplies after-hours calls per week by average call length and 4.33 weeks per month.
What counts as after-hours phone coverage?
After-hours coverage is any period when customers can reach a live employee, answering service, or AI receptionist outside the schedule your regular team staffs. It can include evenings, overnight hours, weekends, and holidays.
Should I include calls that go to voicemail?
Count calls that arrive outside your staffed schedule, including calls that currently reach voicemail. Use your phone records rather than guessing when possible, and separate spam or repeat attempts if they would not require a real conversation.
How accurate is the estimated monthly call usage?
It is a planning estimate based on the weekly call volume and average duration you enter. Seasonal demand, emergencies, duplicate calls, spam filtering, transfers, and unusually long conversations can change actual usage.
