EPC, or earnings per click, is the number affiliate managers need to know cold, because it’s the first number experienced affiliates ask about when evaluating your program. Here’s what it means, how to calculate it, what a competitive number looks like, and four specific things you can do to raise it.
EPC stands for earnings per click. It measures how much an affiliate earns on average for every 100 clicks they send to your offer. The formula is total commissions paid divided by total clicks, multiplied by 100.
So if your affiliates collectively sent 1,000 clicks and earned $600 in commissions, your program EPC is $60 per 100 clicks, or $0.60 per click. That’s the number a savvy affiliate will ask for before deciding whether your program is worth promoting.
Most program managers track traffic, conversion rates, and total revenue. EPC combines those into a single number that tells affiliates exactly how productive their clicks will be. A program with a $6 EPC and a program with a $0.60 EPC can have the same commission rate and look identical on paper, until you do the math.
The Book on Affiliate Management covers EPC alongside every other metric that determines whether your program attracts top affiliates or gets passed over. If you want the full system for building a program that compounds over time, The Book on Affiliate Management is the place to start.
How to calculate your affiliate program EPC
The math is simple: take total commissions paid out over a period, divide by total clicks for the same period, then multiply by 100 to express it per 100 clicks.
EPC = (Total Commissions / Total Clicks) × 100
Here’s a concrete example. You run a program paying 30% commission on a $1,000 product. In a month, affiliates sent 500 clicks, 10 of those converted (2% conversion rate), and you paid out $3,000 in commissions (10 sales × $1,000 × 30%). Your EPC is ($3,000 / 500) × 100 = $600. That’s a strong number.
Now contrast that with a different scenario: same commission rate, same product price, but your conversion rate drops to 0.5%. The same 500 clicks produce 2.5 sales and $750 in commissions. EPC drops to $150. The commission rate hasn’t changed. The product price hasn’t changed. Conversion rate is the only variable that moved, and your EPC dropped 75%.
That’s why EPC matters more than commission rate as a standalone figure. Two programs can offer identical commissions and produce completely different income for an affiliate depending on how well the sales page converts.
You can calculate EPC at the program level (all affiliates combined) or at the individual affiliate level. Program-level EPC is what you quote to prospective affiliates. Individual EPC helps you identify which affiliates are sending quality traffic and which ones aren’t.
Understanding conversion rate is the other half of the EPC equation. If you’re not sure what a healthy conversion rate looks like for a program like yours, this breakdown of good affiliate program conversion rates gives you the benchmarks and how to read your own numbers.
What does a good EPC look like by niche?
EPC varies significantly by product type, price point, and industry. There’s no universal “good” number, but these ranges give you a working baseline.
For digital products, think online courses, memberships, and ebooks, a healthy EPC typically runs $1 to $8 per 100 clicks. High-converting courses with strong sales pages from warm affiliate traffic can push $15 to $25 or higher. If you’re below $1 on digital products with a reasonable price point, your conversion process has a problem worth diagnosing.
Software and SaaS programs generally see lower EPCs because the sales cycle is longer and trial-to-paid conversion adds a second step. A $0.50 to $3 range is typical, though lifetime-deal products can spike well above that during a launch.
Physical product programs pay lower commissions, usually 5-15%, which compresses EPC even when conversion rates are decent. $0.20 to $1.50 is a normal range. Amazon Associates, for reference, has an average EPC under $0.50 for most affiliates across most categories, which is why serious affiliates diversify away from it once they understand the math.
High-ticket programs, anything $2,000 and up, can produce EPCs of $50 to $200 or more even at modest conversion rates because the commission per sale is large enough to compensate. This is why affiliate managers in premium spaces have an easier time recruiting top affiliates even when conversion rates are low.
The benchmark that matters most isn’t your niche average. It’s what competing programs in your exact niche are offering. When an affiliate is deciding between your program and one from a direct competitor, they’re comparing EPCs. If yours is 30% lower, you need a strong reason for them to choose you anyway, and “our product is better” rarely moves the needle without the numbers to support it.
For context on where your commission structure fits into this, a properly structured affiliate program builds EPC potential into the design before you recruit a single partner.
Why EPC is the metric that determines who promotes you
A professional affiliate with a real audience runs their business on EPC data. They know roughly what a click from their list is worth to them based on the programs they currently promote. When they evaluate a new program, they’re comparing your EPC against that benchmark.
If your EPC is below theirs, they pass. You might have a great product and a generous commission rate, but if the numbers don’t pencil out, it’s a no.
This is why smaller and newer programs consistently struggle to recruit top affiliates. Their programs haven’t been optimized, their conversion rates are lower, and their EPC suffers as a result. An affiliate who’s earning a $12 EPC from their top program won’t take a risk on yours if you can only demonstrate a $3 EPC from early data.
The flip side is that a strong EPC opens recruiting conversations that wouldn’t happen otherwise. When you’re going after super affiliates, your EPC is often the first real credential that gets their attention. Showing up with “we convert at 4% and our EPC is $22” is a completely different conversation than “we have a great product and pay 40% commission.”
EPC also affects what affiliates do after they’ve agreed to promote you. A high EPC keeps them engaged. They’ll send more emails, write more content, and push harder because the data tells them it’s worth it. A low EPC, even from an affiliate who likes you personally, leads to deprioritization. They’ll still send you traffic now and then, but you’ll never be in their top tier.
The practical consequence: if your EPC is below your niche average, you’re recruiting from a smaller pool of potential partners and getting less promotion from the ones you do have. Recruiting affiliates who actually promote requires giving them a financial reason to choose you over the alternatives.

Four levers you can pull to increase your EPC
EPC is the product of a few inputs: commission rate, conversion rate, and average order value. Improve any one of them and EPC improves. Here’s where to focus, in order of typical impact.
Conversion rate: This is usually where the biggest gains are. Most program managers set up a sales page once and leave it alone, but conversion rate is highly sensitive to copy, page layout, guarantee structure, and friction in the checkout process. A page converting at 1% that gets to 2% doubles your EPC overnight without touching the commission rate. Specific changes worth testing: stronger headlines and CTAs, extending the guarantee (a 60-day guarantee often converts better than a 30-day, counterintuitively, because buyers feel less pressured), adding live chat or an FAQ to reduce objections, and retargeting ads to recapture visitors who didn’t convert on the first visit. Also check for “leaks” in your funnel: untracked phone numbers and external links that pull visitors off your sales page before they buy, cutting affiliates out of their commission.
Average order value: Because EPC draws from commissions, increasing what the average customer spends has a direct multiplier effect. If your affiliates are sending clicks that convert at 2% and the average cart is $200, you’re getting an EPC that’s exactly twice what you’d get on a $100 cart, commission rate held constant. Upsells, order bumps, and product bundles all raise AOV. Paying commissions on upsells has a compounding effect: it raises both the AOV affiliates benefit from and your program’s attractiveness to high-performers who have upsell-heavy programs to compare you against.
Commission rate: Raising your commission rate directly raises EPC with no other changes required. A program paying 30% commission on $1,000 with a 2% conversion rate has an EPC of $600 per 100 clicks. Raise the commission to 40% and EPC goes to $800, a 33% increase. The constraint is margin: you can’t pay your way into a loss. But many programs underpay relative to what’s competitive in their niche, especially when they’re new and haven’t yet thought about what it takes to attract serious affiliates. Tiered commission structures let you raise effective rates for your best affiliates without raising the baseline rate for everyone.
Affiliate quality: Program-level EPC is an average, and averages hide a lot. In most programs, a handful of affiliates are sending highly qualified traffic that converts at 5-8%, while a longer tail of affiliates sends casual traffic that converts at under 1%. If you calculate EPC across all affiliates, you get a blended number that undersells what’s actually possible for a well-matched affiliate. Segmenting EPC by affiliate type, email vs. content vs. paid traffic, for example, lets you show prospective affiliates a more accurate picture of what they can expect. It also tells you which affiliate types to focus your recruiting on. Customers who become affiliates often produce above-average EPC because they’re promoting to audiences they know well and have genuine conviction about the product.
One more thing worth monitoring: program EPC changes over time, and not always for the obvious reasons. A new upsell, a price increase, or even a sales page redesign can move EPC significantly. Check it quarterly at minimum, and check it after any major change to your funnel. Growing your program without adding new affiliates often comes down to these kinds of optimizations to EPC-driving factors rather than headcount increases.
Writing affiliate emails that communicate your program’s EPC and value takes practice. Affiliate Email Pro is a tool trained on 2,000+ high-performing affiliate emails that handles every communication scenario, from recruiting outreach to launch updates, in a fraction of the time it normally takes.
How to communicate your EPC to prospective affiliates
Once you have an EPC worth talking about, use it in your recruiting outreach. Most program managers lead with commission rate, which is the least compelling way to pitch a serious affiliate. EPC answers the question they’re actually asking: how much will I make if I send you traffic?
A recruiting email that says “we pay 35% commission” makes an affiliate do math. An email that says “our affiliates average a $14 EPC, and our top email affiliates are over $25” tells them exactly what they need to know without any calculation required.
When your program is new and you don’t have real EPC data yet, you can project it. If you know your sales page conversion rate from your own traffic, and you know what you’re paying in commissions, you can build a projected EPC that’s honest about being a projection. Affiliates respect transparency about what the data is based on, and a projected $8 EPC with explained assumptions is more compelling than “we think you’ll do well.”
If your EPC is low or you’re still building it, don’t lead with the number. Work on the conversion rate and AOV first. A low EPC in your recruiting pitch does more damage than leaving the number out entirely, because it anchors the conversation in the wrong place. Get the number to something defensible, then start using it.

FAQ: EPC in affiliate marketing
Is EPC the same as earnings per click or earnings per 100 clicks?
Both usages exist in the industry and both are correct depending on context. Some platforms display EPC as earnings per single click (e.g., $0.06), while others display it per 100 clicks (e.g., $6.00). The underlying number is the same; it’s just a matter of scale. When you’re comparing EPCs across programs or communicating to affiliates, clarify which convention you’re using to avoid confusion. The per-100-clicks convention is more common in affiliate management contexts because it produces cleaner numbers and is easier to compare against historical data.
Can EPC be gamed or artificially inflated?
Yes, and experienced affiliates watch for this. If a program reports EPC based on a tiny sample of clicks, or based only on their highest-performing affiliates, the number can look much better than what a typical affiliate will actually experience. When you present your EPC, be clear about the sample size and whether it reflects all affiliates or just a subset. Affiliates who’ve been around long enough to get burned by misleading EPC claims will ask. Transparency about the data builds more trust than a polished number.
Should I calculate EPC per affiliate or per program?
Both, for different reasons. Program-level EPC is what you use in recruiting conversations, because it gives prospective affiliates a baseline expectation. Individual affiliate EPC helps you identify who’s sending quality traffic and who isn’t. An affiliate with unusually low EPC relative to the program average is either sending poor-fit traffic or not warming their audience before sending. That’s a coaching conversation worth having. An affiliate with unusually high EPC is someone to build a closer relationship with and potentially offer a tiered commission to keep them motivated.
How often should I recalculate my program’s EPC?
Monthly is a reasonable default for most programs. Track it over rolling 30-day and 90-day windows so you can see both short-term fluctuations and longer trends. Any time you make a significant change to your sales funnel, pricing, commission structure, or traffic mix, recalculate shortly after to see the impact. A sudden drop in EPC without an obvious cause is worth investigating immediately, as it sometimes signals a technical problem with your tracking or a conversion issue introduced by a site change.
What’s the relationship between EPC and affiliate recruitment success?
A direct one. Affiliates who have options, meaning the experienced ones with real audiences you actually want, compare EPCs across programs before committing promotional time. A program with a demonstrably higher EPC than competitors in the same niche has a recruiting advantage that’s hard to overcome through relationship-building alone. Conversely, if your EPC is significantly below the niche benchmark, you’re likely only attracting newer affiliates who don’t yet know what a competitive number looks like. Raising EPC is one of the most reliable ways to upgrade the quality of your affiliate base over time.
