Calculate affiliate EPC from your campaign revenue and clicks, then compare offers and see whether your earnings per click can cover your traffic cost.
Affiliate EPC Calculator
EPC = revenue ÷ clicks. If traffic cost is entered, CPC = cost ÷ clicks and profit per click = EPC − CPC.
How to Calculate EPC
EPC = Affiliate Revenue ÷ Number of Clicks
For example, $700 in affiliate commissions from 1,000 clicks gives an EPC of $0.70. EPC can be calculated for an offer, campaign, traffic source, landing page or time period as long as the revenue and clicks use the same scope.
What Is a Good EPC?
There is no universal good EPC. A $0.50 EPC may work with cheap traffic and fail with an expensive source. Compare your EPC with CPC, conversion rate, GEO, traffic quality and other campaign costs.
EPC vs. CPC
EPC tells you what a click earns; CPC tells you what that click costs. If EPC is $1.20 and CPC is $0.70, the campaign has $0.50 per click before other costs. If CPC is $1.40, the same offer loses $0.20 per click.
Compare Affiliate Offers by EPC
A higher payout does not automatically make an offer better. An offer paying $100 but converting poorly can have a lower EPC than an offer paying $35 with a much stronger conversion rate. Use Compare A vs B above to evaluate revenue per click on the same traffic.
EPC and Break-Even CPC
In a simplified model where traffic cost is the only variable cost, break-even CPC is approximately equal to EPC. Your practical CPC ceiling should be lower once you include tracker fees, creatives, refunds, chargebacks and other operating costs.
