How is EPC Calculated? - Invoca

The formula Invoca uses to calculate Earnings per 100 Calls (EPC), with a worked example.

What EPC measures

Average Earnings per 100 Calls (EPC) is calculated the same way many networks calculate Earnings per 100 Clicks, but using call volume instead of click volume.

The formula

EPC = (Total Earnings / Total Calls) x 100 In the Overview Report, Total Earnings is shown in the “Total Earned” column, and Total Calls is shown in the “Calls” column. Total Calls does not include test calls made during the reporting period. Invoca reports Average EPC over both the past 7 days and the past 30 days.

Example

Suppose you earned $600 from a total of 300 calls over 7 days. Your 7-day average EPC is:

EPC = ($600 / 300) * 100 = $200.00

This means that, on average, every 100 calls generated $200 in earnings during that period.
