Affiliate Commission Structures: How to Set Rates That Attract Good Partners

Your commission is the first thing a good publisher looks at and the last thing you want to change once partners are live. Set it too low and the content sites and creators you actually want never apply. Set it too high, or flat across every partner type, and you end up paying full price for sales that coupon and cashback sites simply intercepted at checkout.

This guide is for brands setting or fixing an affiliate commission structure. It covers flat, tiered and hybrid models, cookie windows, new-customer bonuses, paying content and coupon partners differently, a worked margin example you can copy, published rates you can benchmark against, and the mistakes we see most often.

Flat, tiered and hybrid commission structures

Almost every affiliate program uses one of three shapes, or a mix of them.

For most brands, the right starting point is a single base rate plus a higher rate for new customers. Add tiers once you know what your best partners actually deliver in a month, so you can set the first threshold just above where your good partners already are. If you work with creators on fees as well as commission, our guide to structuring creator commissions covers flat fees, CPA and fee-plus-commission deals in detail.

Making tiers work

• Use two or three tiers, not six. Each tier should be a meaningful step up, not a rounding error.
• Measure on a period partners can follow: calendar month or quarter, based on approved (not pending) sales.
• Decide what happens when a partner drops below a tier and say it in your terms. A one-period grace before stepping down avoids arguments.
• Tier on what you value. Tiering on new-customer orders rather than total revenue stops coupon traffic from climbing the ladder on existing customers.

Cookie windows: how long a click earns credit

The cookie window (or referral window) is how long after a click a sale still earns the partner commission. It is the second number partners compare after the rate. For reference, Amazon Associates pays on items added to the cart within 24 hours of the click (Amazon Associates help). Brand programs set their own windows, and publishers compare them, so check what your direct competitors publish.

How to choose yours:

• Match your buying cycle. Check your network’s click-to-sale time report (or your own analytics) to see how many days typically pass between a first visit and an order. Products people research for weeks need a window that covers that.
• Remember tracking limits. A long window means little if the cookie doesn’t survive. Safari’s Intelligent Tracking Prevention capped cookies set through JavaScript at seven days when ITP 2.1 launched (WebKit). Use your network’s first-party or server-side tracking so the window you publish is the window partners actually get.
• Publish it and keep it stable. Shortening a window quietly is one of the fastest ways to lose content partners.

New-customer bonuses

If repeat customers are a large share of your revenue, paying the same rate on every order means paying partners again for customers you already had. Many platforms let you split payouts by customer type. Awin, for example, lists “new or existing customers” among the rules you can use to build commission groups on its advertiser plans (Awin pricing).

Common ways to reward new customers:

• A higher percentage on first orders and a lower one on returning customers.
• A flat bonus per new customer on top of the base rate, which is easy for partners to understand.
• For subscriptions, a fixed amount per new subscriber rather than a percentage of a small first payment.

Before you launch a split, confirm how your platform decides who is “new” (usually your customer database or a flag in the conversion tag) and test it. A new-customer rate that never fires is worse than no split at all.

Paying coupon and content partners differently

Partner types play different roles. Content, review and creator partners tend to introduce a product while people are researching. Coupon, cashback and loyalty partners tend to be the last click before checkout. In impact.com’s 2025 benchmark of 2,368 North American retail brands, loyalty and rewards partners drove half of all transactions, while network and content partners drove most of the research-phase clicks (impact.com benchmark). If you pay both the same rate, the partners closest to checkout collect most of your commission.

Ways to pay for the role a partner plays:

• Commission groups by partner type. Put coupon and cashback partners on a lower base rate and content partners on a higher one. Most networks let you assign partners to groups.
• Code-based rules. Pay less (or nothing) when an unapproved or leaked code is used, and say so in your terms. Awin lists coupon code as one of its commission-group rules, alongside publisher and product (Awin pricing).
• Placement fees or bonuses for content. A flat fee for a guaranteed placement in a “best of” article can be fairer than hoping it converts on last click.
• Multi-touch or assist rules where your platform supports them, so the partner who introduced the buyer gets a share.

The goal isn’t to punish coupon partners. Used deliberately, they help conversion. It is to make sure the partners who bring you new customers can earn more with you than with a competitor.

The margin math: a worked example

This is an illustrative example with round numbers, not data from any brand. Swap in your own figures.

Now decide what you are willing to spend to win a new customer. If customers in this example typically come back, you might accept breaking even on the first order. If they rarely return, you need profit on the first order. A sensible structure for this example:

• New customers: 15% ($12.00), leaving about $21 of contribution after the network fee.
• Returning customers: 6% ($4.80), because you would likely have won much of that revenue anyway.
• Top tier for content partners: 20% on new customers ($16.00) once they pass a monthly threshold. Still well inside the $33.20 room.

Check the result against your all-in cost of sale (commissions, network fees, bonuses and placement fees ÷ affiliate revenue) every month. Our guide to affiliate program KPIs shows how to track it alongside new-customer share and reversal rate. The fee line uses Awin’s published Access plan ($49 a month plus a 3.5% tracking fee per transaction, Awin pricing); other networks price differently, so use your own contract.

Published commission rates you can benchmark against

Most “average commission by industry” figures online come without a source, so we don’t repeat them. Two published references are worth knowing.

Amazon Associates’ category rates. Many content publishers can link to Amazon instead of you, so Amazon’s published rates are a floor they compare against. Selected US rates from Amazon’s Standard Commission Income table (Amazon Associates, checked 21 October 2026):

A partner choosing between linking to your product on Amazon and linking to your own site will usually earn more with your program. Make that difference obvious on your affiliate page.

Your direct competitors’ programs. This is the benchmark that matters most. Look up competitors on your network’s advertiser directory and their own “affiliates” or “partners” pages, and note the base rate, any new-customer rate and the cookie window. impact.com’s benchmark also found that brands raised commission rates by 7% in November 2025 to compete for placement during the busiest research period (impact.com benchmark), so expect competitor offers to move around peak season.

Common commission mistakes

• Copying a competitor’s rate without checking your margins. Their margin, AOV and repeat rate aren’t yours.
• One rate for every partner type. It quietly shifts budget to whoever is closest to checkout.
• Launching high, then cutting. Partners remember. Start at a rate you can hold and use time-limited bonuses for launches.
• Tiers nobody can reach. If no partner hits tier two within a quarter, the threshold is decoration.
• No rules on codes and brand bidding. Leaked codes and partners bidding on your brand name can earn commission on sales you would have made anyway. Write the rules into your terms. Our step-by-step guide to starting an affiliate program lists what the terms should cover.
• Never reviewing the structure. Review it at least twice a year and before peak season. If revenue has stalled, commission is only one of the causes; see why your affiliate program is not growing.
