How much should you pay your affiliates?

Every founder who sets up an affiliate program asks the same question within the first hour of setup. “How much should I pay my affiliates?” And every Google search returns the same unhelpful answer. “Industry standard is 10-20%.” Or some blog post that lists averages by category and calls it a day.

Here’s the thing. “Industry standard” is not a strategy. It’s what happens when nobody wants to do the actual math, so they copy what everyone else is doing and hope it works out. If you pay industry standard without understanding why, you’ll either overpay (and bleed margin on every sale) or underpay (and watch your best affiliates walk to a competitor who did the math).

The good news is the math isn’t hard. You need to know three things about your business, run a quick calculation, and pick a number you can actually defend. Let’s walk through it.

The three numbers you need

Before you can answer “what should I pay,” you need to answer three questions about your own business first.

The first is your gross margin per sale. Not your revenue. Not your list price. Your margin. What’s left over after you’ve paid for the cost of the product, the payment processor’s cut, and any direct costs of fulfilling the order. If you sell a $100 product and it costs you $30 to make and ship, your gross margin is $70. Everything you pay an affiliate comes out of that $70, not out of the $100.

The second is the lifetime value of an affiliate-driven customer. This one surprises people, because the lifetime value of an affiliate-driven customer is almost never the same as the lifetime value of a direct customer. Customers who come through affiliate links tend to have different retention patterns. Sometimes they’re lower because they were pulled in by a coupon and churn quickly. Sometimes they’re higher because the affiliate pre-sold them on the product and they arrive ready to buy again. You won’t know until you’ve been running the program for a few months, but even a rough estimate gets you closer to a real number than ignoring the question.

The third is what your direct competitors are paying. If you want a walkthrough of the math for a pool-based creator payout instead of a straight commission, distributor compensation modeling shows you how to size a pool and assign metric weights with worked examples. Not “industry average” across thousands of programs. The handful of programs that your target affiliates would realistically compare you to. If your affiliates are choosing between promoting you and promoting a competitor, and your competitor is paying 25% and you’re paying 10%, you’re going to lose that competition no matter how great your product is.

With those three numbers in hand, you can actually start picking a rate.

Calculating the maximum sustainable rate

The ceiling on what you can pay is set by your gross margin. Pay more than your gross margin on a sale and you’re losing money on that sale, which only makes sense if the lifetime value makes up for it later.

Here’s the basic calculation. Take your gross margin per sale and that’s your hard ceiling for a single transaction. If your gross margin is 40% of revenue, you literally cannot pay 50% commission on first-sale affiliate deals without losing money. You’d need repeat purchases to break even.

The soft ceiling is lower. You want to pay enough to be competitive, but not so much that you can’t afford to scale operations, pay yourself, or invest in marketing beyond affiliates. A program that consumes 100% of your gross margin on every sale isn’t a growth engine. It’s a charity. Leave yourself some room.

For most businesses, the realistic max is somewhere between 40% and 70% of your gross margin. That range gives you room to grow, room to adjust, and room to survive a bad quarter without pulling the plug on the program.

Why most programs pay below the maximum

If you could sustainably pay 70% of your margin and still grow, why don’t more programs? A few reasons.

The first is that affiliates are only one channel. If you’re running paid ads, doing content marketing, running a partnership program, and paying affiliates, each channel competes for margin. Burning your entire margin on affiliates leaves nothing for the other channels, which might be cheaper per customer on average.

The second is that affiliate quality varies. Some affiliates will drive genuinely new customers who wouldn’t have found you otherwise. Some will intercept customers who were already going to buy. You’re paying the same rate to both groups even though they’re delivering wildly different value. If you set your rate based on “what a great affiliate delivers,” you’ll overpay the intercept affiliates by a huge margin.

The third is reserve. You want to be able to give top performers a bump without having to re-negotiate your entire program. If you start at the ceiling, you have nowhere to go when a strategic partner wants a custom deal.

A practical starting framework

If you want a number to start with, here’s one that works for most new programs.

Start at 50% of your gross margin per sale. Round down to a clean percentage that’s easy to explain (15%, 20%, 25%, not 23.7%). Run the program for 90 days with that rate. After 90 days, look at the data. Are you getting enough affiliate interest? If not, the rate is too low. Are the affiliates who joined actually producing sales, or are they sitting dormant? If they’re dormant, the problem isn’t the rate, it’s recruitment and quality. Don’t raise the rate to fix a recruitment problem. Fix recruitment.

After 90 days with real data, you can adjust with confidence. Raise the rate if you need to attract better affiliates. Hold steady if the program is working. Layer on a tier for top performers if you want to reward the affiliates who are actually producing.

When to pay flat fees instead of percentages

Percentage commissions are the default, but they’re not always the right choice. There are two situations where a flat fee makes more sense.

The first is lead generation. If you’re paying affiliates to drive leads rather than sales, the sale hasn’t happened yet, so there’s no percentage to calculate from. You pay a fixed amount per qualified lead, period. The pay per lead affiliate program recipe is configured for this pattern out of the box.

The second is customer referrals. When your existing customers refer friends, you want the reward to be something they can explain in a text message. “Tell a friend, earn $10” is vastly more shareable than “Tell a friend, earn 15% of their first order.” The refer a friend program recipe defaults to a flat $10 reward because that’s the pattern that actually works for customer referral programs.

For professional affiliates promoting your product to their audience, percentages still win because they scale with order size. But for lead gen and customer referrals, flat wins on simplicity. The tradeoffs between the two are covered in choosing an incentive structure.

Tiered programs solve the “pay top performers more” problem

Here’s the question every program operator hits eventually. “I want to pay my top three affiliates more than my regular affiliates, but I don’t want to pay everyone the top rate because I can’t afford it.”

The answer isn’t to set a custom rate on those top three affiliates. That’s how affiliate programs slowly decay into an unmaintainable mess of special cases. The answer is tiers.

You create a “Standard” program at your base rate, and a “Top Performer” program at a higher rate, and you move affiliates between them based on performance. Everyone starts in Standard. When someone hits a threshold (say, $5,000 in tracked sales), they get moved to Top Performer and earn the higher rate on future conversions. The tiered affiliate program recipe has this structure ready to go, and the reasoning behind keeping rates on programs instead of on individual collaborators is covered in why rates live on programs, not collaborators.

The advantage is that your program structure stays clean. Anyone looking at the Top Performer program sees “25% commission” and knows exactly what’s going on. There’s no digging through individual collaborator profiles to find buried overrides. When you want to raise the top tier to 27%, you edit one field and every top performer gets the bump.

Pick a number and run with it

The mistake most founders make is treating commission rate as a decision they need to get perfect on day one. It isn’t. It’s a variable you adjust based on data.

Pick a rate based on the math. Start at 50% of your gross margin, run the basic affiliate program recipe to get yourself set up, and give it 90 days of real operation. Then look at the data and adjust.

The founders who succeed with affiliate programs are the ones who treat the commission rate as a lever they can pull, not a sacred number they set once and never revisit. Start with a defensible rate, watch what happens, and adjust. That’s the whole game.
