CPS Commission Rates: Check the Revenue Base Before Comparing Offers

A headline commission rate is only half of a CPS offer. The other half is the revenue to which that rate applies. For affiliates comparing ecommerce offers across a global affiliate network, a lower percentage can produce a higher approved commission when the eligible basket is larger. Start with the calculation, then evaluate the traffic opportunity.

Ask what counts as eligible revenue

An offer may calculate commission on merchandise value after discounts, exclude delivery charges, or restrict eligibility to selected products. These are contract-specific conditions, not universal network rules. Request a worked example showing the customer payment, deductions, eligible revenue, rate, and resulting commission. A percentage without this bridge is difficult to compare responsibly.

Separate order-level deductions from item-level exclusions. If a customer buys an eligible product and an excluded accessory in the same basket, the full checkout total may never be commissionable. A publisher should understand that distinction before using average order value to forecast earnings.

Compare two hypothetical orders

Consider an illustrative order with $120 of merchandise, a $20 discount, and $10 delivery. If an offer pays 12% on merchandise after discount and excludes delivery, the eligible base is $100 and the provisional commission is $12. The customer payment of $110 is not the denominator for this calculation.

Now consider a different offer paying 10% on an eligible merchandise value of $140. Its provisional commission is $14. The second offer produces more commission per order in this example, but that alone does not establish better performance: conversion probability, reversals, customer intent, and traffic cost still matter. These numbers are illustrations, not BlueFriday offer terms or performance results.

Keep provisional and approved earnings separate

A commission calculated at checkout may change after order validation. Record provisional commission and final approved commission in different columns, linked by a pseudonymous order reference. When an order is partially returned, ask whether the adjustment follows individual line items or another agreed rule. Do not assume that a partial return always cancels the entire commission.

For a fair comparison, use orders that have completed the same validation window. Mixing mature approved orders from one merchant with recent pending orders from another creates an apparent winner before the evidence is comparable.

Build a compact offer comparison sheet

• Document the eligible products and revenue definition.
• State how discounts and delivery charges affect the base.
• Include the rate, any fixed bonus, and its conditions separately.
• Record partial-return treatment and validation timing.
• Compare approved commission per eligible click using a consistent click definition and mature cohorts.

For paid campaigns, compare those observed earnings with traffic cost at the same campaign scope. Missing validation data should remain visibly unresolved rather than being treated as approved revenue.

Make the calculation usable across teams

Advertisers can reduce ambiguity by supplying one ordinary basket, one discounted basket, and one partially returned basket as examples. Media buyers can then translate the approved earnings into campaign decisions without reconstructing the commercial rules from a headline rate. The useful comparison is a traceable path from eligible order value to approved commission.
