Formula to Calculate The Number of Missed Calls KPI

To compute the “Number of Missed Calls” KPI, you need to know two primary data points: the total number of incoming calls and the number of answered calls.



Let’s assume for ABC Tech Support, in the month of January:

Total Incoming Calls = 5,000
Number of Answered Calls = 4,200

Using the formula:
Number of Missed Calls=5,000−4,200
Number of Missed Calls= 800

So, ABC Tech Support missed 800 calls in January. This gives them a clear number to work with, and they can dive deeper to understand why these calls were missed and how to reduce this number in the future.
