Definition
A performance metric calculated as total commissions earned divided by total clicks. EPC helps affiliates compare the profitability of different offers.
Formula
Total Commissions ÷ Total Clicks = EPCExamples
If you earned $1,000 in commissions from 100 clicks, your EPC is $10.
A program with $50 EPC is more profitable per click than a program with $5 EPC.

Why EPC matters for affiliates
EPC answers the real question: which offer makes me the most money per click? A program can advertise a fat commission, but if it barely converts, your earnings per click stay low. EPC blends payout and conversion into one number you can rank by.
That makes it the go-to metric when deciding where to send limited traffic. The offer with the higher EPC is usually the smarter place to point your audience.
How EPC is calculated
The formula is simple division:
- Total commissions ÷ total clicks = EPC
- Example: $1,000 in commissions from 100 clicks = a $10 EPC.
EPC is often shown per 100 clicks on some networks, so a "$10 EPC" might mean $10 for every 100 clicks elsewhere. Always confirm the basis before comparing two programs.
EPC vs conversion rate and commission
EPC is more complete than either number alone. Conversion rate tells you how often clicks turn into sales. Commission tells you what each sale pays. EPC multiplies them into real per-click value.
One more caution: a network EPC reflects all affiliates' average results, while your EPC reflects your specific traffic. Quality traffic can beat the network average, and poor traffic can fall well below it.
Frequently asked questions
What is a good EPC?
There is no universal benchmark because it depends on the niche and price point. High-ticket B2B SaaS can produce EPCs of several dollars or more, while low-cost consumer offers may sit under a dollar. Rather than chasing an absolute number, compare EPC between offers you could realistically promote to the same audience.
Is a higher commission rate always better than a higher EPC?
No, EPC is usually the more reliable signal. A 50% commission on an offer that rarely converts can earn less per click than a 20% commission on an offer that converts well. Because EPC combines payout and conversion rate, it shows actual earning power per click, which a raw commission rate hides.
Why is the network EPC different from my own EPC?
Network EPC is the average across all affiliates promoting an offer, blending strong and weak traffic. Your EPC reflects only your audience and how well it converts. Targeted, high-intent traffic can far exceed the network average, while broad or mismatched traffic often falls below it, so treat network EPC as a rough guide.
How many clicks do I need before EPC is reliable?
EPC from a handful of clicks is noisy and can swing wildly on a single sale. As a rough rule, you want at least a few hundred clicks before the figure stabilizes. The more clicks behind an EPC, the more confidently you can use it to compare offers and forecast earnings.
