Affiliate EPC Calculator
Earnings Per Click (EPC) is the core profitability metric for affiliate marketing. It tells you how much commission you earn, on average, for each visitor you send to an advertiser. EPC allows you to compare the value of different affiliate offers on a common basis, regardless of commission rate, conversion rate, or average order value. You can also compare EPC against your cost per click from paid traffic to determine whether a campaign is profitable. Enter your total affiliate commissions earned and total clicks sent to calculate EPC.
Affiliate EPC formula
EPC = Total Earnings / Total Clicks Profit Per Click = EPC - Traffic CPC
A positive profit per click indicates a profitable campaign. EPC per 100 clicks (used by some networks) = EPC * 100.
Using EPC to compare affiliate offers
- Compare EPC across offers in the same niche to find which converts best for your audience.
- EPC can decline over time as an audience saturates. Refresh creatives or test new offers when EPC drops more than 20% from its peak.
- Segment EPC by traffic source: search traffic and email often produce very different EPC from the same offer.
- The relationship EPC greater than CPC is required for profitable paid affiliate arbitrage. Even a small margin (EPC $1.50, CPC $0.80) compounds to significant profit at scale.
Affiliate EPC: frequently asked questions
What is affiliate EPC (earnings per click)?
EPC is the average commission earned for each click sent to an advertiser through an affiliate link. It is calculated as total earnings divided by total clicks. An EPC of $1.50 means you earn $1.50 on average for every visitor you send.
How is EPC different from CPC?
CPC (Cost Per Click) is what you pay per click when buying traffic. EPC is what you earn per click through affiliate links. If your EPC exceeds your CPC on paid traffic, the arbitrage is profitable. EPC $1.50 minus CPC $0.80 yields $0.70 profit per click.
What is a good EPC for affiliate marketing?
EPC varies enormously by niche and traffic quality. High-value niches like finance, insurance, and legal typically see EPC of $5 to $50. Consumer products run $0.50 to $3. The key metric is comparing EPC to your cost per click from your traffic source.
Should I use 100-click EPC or overall EPC?
Many affiliate networks report EPC per 100 clicks (multiplied by 100). This makes low-volume offers more comparable. Make sure you are comparing EPC on the same basis across offers. This calculator uses raw EPC (total earnings / total clicks).
How can I improve EPC?
Send more targeted traffic (better keyword match or audience fit), improve landing page relevance (better pre-selling), test different affiliate offers for the same audience, and use comparison content to increase purchase intent before the click.
