How to use the missed call revenue calculator

  1. Check your phone or call-tracking report for the number of inbound calls in a typical week.
  2. Note how many of those calls went unanswered or to voicemail — your missed-call rate.
  3. Estimate what share of callers are new customers asking for a quote or booking (not existing customers, suppliers or spam).
  4. Use your own close rate and average job or order value from your sales records.

The formula

  • Missed new-customer calls per month = weekly calls × 4.33 × missed rate × share of new-customer calls.
  • Lost customers per month = missed new-customer calls × share of missed callers who would not call back × close rate.
  • Lost revenue per month = lost customers × average job value. Lost revenue per year = monthly figure × 12.
  • Recoverable revenue = lost revenue × the share of missed calls you expect an always-on answering system to handle.

FAQs

How do I calculate the cost of missed calls?

Multiply the number of missed calls from potential new customers by the share who won't call back, then by your close rate and your average job value. This calculator does that for weekly, monthly and yearly figures using your own inputs.

What counts as a missed call?

Any inbound call that isn't answered live — calls that ring out, go to voicemail, or are abandoned on hold.

How can I stop missing business calls?

Options include call forwarding to a colleague, a human answering service, missed-call text-back, or an AI receptionist that answers every call 24/7, books jobs and sends you a summary.
