Start Free TrialHow the Calculation Works
The calculator multiplies your weekly missed calls by the average weeks in a month, then by how much a typical job is worth and how often a new caller becomes a customer.
Missed calls / week × 4.33 × average job value × close rate= estimated revenue at risk per month

How to Stop Losing Revenue to Missed Calls
Answer every call, even when you can't
An AI receptionist picks up in seconds, answers questions, and books the job while you're on a ladder or with a customer.
AI call answering →Cover nights and weekends
Many urgent calls come in after hours. Forward your line after closing so those callers still reach someone.
After-hours answering →Text back anyone who hangs up
An automatic text to callers who hang up gives them a reason to wait instead of calling the next business.

Monthly lost revenue = missed calls per week × 4.33 weeks × average job value × close rate. For example, 5 missed calls a week at a $350 average job and a 30% close rate is about $2,270 a month, or $27,280 a year.
Check your phone carrier's or VoIP provider's call log for unanswered and voicemail calls over the last two to four weeks, then divide by the number of weeks. Count missed calls from unknown numbers too — those are usually new customers.
Use the share of new callers who normally become paying customers. If you don't track it, 20–40% is a reasonable starting range for service businesses. Emergency trades like plumbing and HVAC tend to be higher; considered purchases like legal or real estate tend to be lower.
