EPC (Earnings Per Click)

Quick Definition

A critical metric measuring the average revenue generated by a publisher or affiliate for every 100 clicks sent to an offer.

Formula / Calculation / Syntax

EPC = (Total Commission Earned / Total Clicks Sent) * 100

Earnings Per Click (EPC) allows media buyers, affiliate managers, and publishers to instantly evaluate offer profitability regardless of payout differences. An offer with a $10 payout and 10% conversion rate yields higher EPC than a $100 payout offer with a 0.5% conversion rate.
