A missed call is not an administrative nuisance. It is a revenue event with a calculable value, and the calculation is simple enough to do on the back of a docket.
The formula
Expected value of one missed call = average job value × close rate on answered enquiries
The logic: a missed call is a lost opportunity, but not every opportunity would have converted. Discounting the job value by your normal close rate gives the expected loss rather than an inflated headline figure.
Worked example
Take a business with an average job value of $800 and a 40% close rate on enquiries it actually speaks to:
- One missed call: $800 × 0.40 = $320 in expected revenue
- Ten missed calls in a week: $3,200
- Across 48 working weeks: $153,600
These are illustrative inputs, not a benchmark. Substitute your own figures, the point is the shape of the annual number, which is usually what changes an operator's mind.
What the formula deliberately leaves out
It excludes repeat work from that customer, referrals they would have generated, and any reputational effect from callers who could not get through. It also assumes a missed call is genuinely lost rather than recovered later. Those omissions all push in the same direction, which is why this should be read as a conservative estimate.
Be honest about the input you are least sure of
Most operators underestimate how many calls they miss, because an unanswered call leaves no trace in the diary. If your phone system reports missed calls, use the real number rather than an impression.
Run it on your figures with the lead leak calculator, or read the fuller treatment in what a missed call actually costs.
