# How to Structure Affiliate Commission Tiers for New vs. Returning Customers

Most affiliate programmes handle this with a simple rule: pay more for new customers, less for returning ones. It's the industry default for a reason — it's easy to explain to partners and easy to track. But it's also a rough proxy for something more specific, and once you understand what that something is, the new-vs-returning split starts to look like the simplified version of a better question.

The default split, and why it exists

The common benchmark most growth-stage brands land on is a hybrid: something like 15-25% commission on new customers and 5-10% on returning ones. The logic is straightforward — a returning customer likely would have bought again regardless of whether an affiliate was involved, so paying full commission on that sale is really just overpaying for acquisition that never happened. A new customer, by contrast, represents genuine long-term revenue potential the business didn't have before.

It's not a universal rule, though. Some brands run the split the other way — a slightly lower rate on new customers, a slightly higher one on returning customers — specifically to motivate affiliates to bring back previous shoppers when retention is the priority instead of growth.

There's also a fairness argument worth acknowledging. Affiliates generally can't tell whether the person clicking their link is a new or returning customer — they're simply exposing the brand and driving a click that converts, which has real value for brand exposure regardless of the label attached to the sale afterward. A programme that leans too hard on the new-customer-only logic risks treating affiliate purely as an acquisition channel, when a genuinely engaged partner is often just as valuable for retention.

Where LTV comes in

New-vs-returning is really a blunt stand-in for a more precise question: what is this customer actually worth? That's what customer lifetime value answers directly.

LTV is typically calculated as average order value multiplied by purchase frequency multiplied by customer lifespan. Once you know that number, alongside your margins, you can build a commission structure around actual value instead of a binary label. The general guidance is that total commission should represent somewhere around 20-30% of gross profit margin, checked against a target LTV-to-CAC ratio of at least 3:1 — meaning a customer should be worth at least three times what it costs to acquire them through that channel.

This is where LTV-based thinking actually outperforms a flat new-customer rate. Not all "new" customers are equal. A coupon or cashback partner might deliver a high volume of new customers with a low repeat rate, while a creator or content partner might drive fewer new customers who go on to buy multiple times. A flat new-customer commission treats both of those partners identically. An LTV-aware structure doesn't — it lets you segment by partner type and adjust payouts based on the long-term value of the customers each partner actually brings in, not just the volume.

How the two ideas actually fit together

These aren't competing models — new-vs-returning is usually the simpler operational layer, and LTV is the more advanced layer used to refine it. In practice, a lot of programmes run both: a baseline new-vs-returning split for simplicity and easy tracking, with an LTV lens applied on top to justify different rates for different partner types, or to identify which affiliates are worth a higher rate even within the same new-customer tier.

You can even calculate this per affiliate specifically — commission paid per customer, multiplied by how many repeat purchases that customer goes on to make through that affiliate's link. That tells you which partners are genuinely valuable long-term, rather than which ones simply produce the most new sign-ups in a given month.

What this means for structuring your own programme

A few practical starting points:

• Calculate your LTV first, even roughly. Average order value × purchase frequency × customer lifespan gets you close enough to start.

• Set commission as a percentage of margin, not a guess. Somewhere around 20-30% of gross profit margin is the common range, adjusted for your specific economics.

• Segment by partner type before segmenting by new-vs-returning. A coupon site and a creator partner rarely deserve the same commission logic, even if both are technically bringing in "new" customers.

• Track LTV per affiliate, not just per sale. This is the number that tells you which partners are actually worth keeping at a premium rate.

New-vs-returning is a fine place to start, especially for a newer programme without much data yet. But it's worth treating it as the entry point rather than the finished structure — the real question underneath it is always about value, not just whether a customer has bought before.

Where your own programme's commission logic currently stands, and whether it's built around real value or just around new-vs-returning as a proxy, is worth a direct look.
