Introduction
A percentage commission sounds simple: earn a fixed share of every sale you refer. In practice, the advertised percentage is only one part of the calculation. Your actual earnings depend on the value of the qualifying order, the product category, programme rules, exclusions, returns, taxes, discounts, and sometimes even maximum payout limits. As a result, a programme offering 12% commission can generate less income than one offering 4% if the higher-rate products are inexpensive or subject to restrictions.
For anyone building affiliate websites, understanding how percentage commissions are calculated is more valuable than chasing the biggest headline rate. The real question is how much qualifying revenue is left after the merchant applies its rules.
How Percentage Commissions Are Calculated
Most affiliate programmes calculate commission as a percentage of the qualifying purchase value rather than the product’s advertised price. Although the exact definition varies between merchants, qualifying revenue is commonly the eligible value of the completed order after adjustments required by the programme’s terms. Amazon Associates, for example, pays fixed percentage rates by product category on qualifying revenue rather than applying one universal percentage across every item.

- Qualifying revenue: £200
- Commission: £8
However, the calculation can change if:
- A discount or voucher reduces the eligible purchase value.
- Some items in the basket belong to different commission categories.
- Certain products are excluded from commission.
- The customer later returns or cancels the purchase.
- The programme applies a maximum commission per item.
The visible percentage is therefore only one variable in a larger formula.
Why Order Value Often Matters More Than the Percentage
A common mistake is comparing commission rates without considering product price.
Consider three examples:
ProductCommission RateOrder ValueCommissionKitchen appliance4%£600£24Clothing item10%£40£4Software licence20%£50£10
Although the second product offers the highest percentage, it produces the lowest payout because the purchase value is much smaller.
This is why affiliates frequently calculate earnings per referred sale rather than comparing percentages alone. Expensive products with modest commission rates can outperform low-priced products paying much higher percentages.
Average order value also matters. A website recommending premium office chairs, professional cameras or specialist tools may earn more from relatively few conversions than a site promoting inexpensive accessories with higher stated percentages.
Why Category Rates Change Earnings
Many large affiliate programmes pay different percentages depending on the type of product sold rather than using one universal rate.
Amazon Associates is a well-known example. Its commission schedule assigns fixed rates to specific categories, with some categories paying substantially more than others, while certain products qualify only for fixed bounties or special commission structures.

This creates several practical consequences.
A page reviewing premium kitchen equipment may earn differently from a page reviewing consumer electronics even if both generate identical sales values. Likewise, two products sold at exactly the same price can produce different commissions simply because they belong to different commission categories.
Merchants structure these rates around their own economics. Products with larger profit margins generally allow higher affiliate commissions, while low-margin or highly competitive categories often pay less. Affiliate networks also recommend advertisers align commission rates with product profitability instead of applying identical rates across every category.

When a Bigger Percentage Pays Less
The headline commission rate becomes misleading whenever one or more of the following applies.
Low-priced products. A 15% commission on a £15 item earns only £2.25.
Different product categories. Two £300 purchases can generate different commissions because each category has its own rate.
Mixed shopping baskets. Customers often buy multiple items together, with each item earning according to its own eligible rate rather than a single percentage across the whole order.
Programme limits. Some merchants cap commission on specific products regardless of selling price. Amazon, for example, applies a maximum standard commission of $200 on qualifying fine art purchases despite their potentially much higher selling prices.

These differences explain why experienced affiliates usually model expected earnings using real sales data instead of advertised percentages.
Common Exclusions, Caps and Reversals to Check
Before comparing affiliate programmes, examine the detailed commission rules rather than the promotional headline.
Pay particular attention to:
- Excluded product categories that generate no commission.
- Category-specific commission tables instead of one advertised maximum rate.
- Maximum commission caps per product or transaction.
- Returned, refunded or cancelled orders, which normally reverse previously credited commission.
- Special events or bounty payments that replace percentage commissions for certain actions.
- Products sold by third parties or special marketplaces, which may follow different eligibility rules.
A programme advertising “up to 10%” may pay that rate only on selected categories, with many purchases qualifying for lower percentages or entirely different payment structures. Amazon’s published commission schedule illustrates this distinction by listing category-specific rates and separate commission limitations rather than one universal percentage.

Focus on Expected Revenue, Not the Headline Rate
The most profitable affiliate opportunities usually come from balancing four variables together:
- Commission percentage.
- Typical order value.
- Conversion rate.
- Programme rules affecting qualifying revenue.
A lower commission percentage attached to consistently expensive products can generate more income than a high percentage on inexpensive items. Likewise, programmes with transparent category rules and fewer exclusions may outperform those advertising impressive maximum percentages that apply only in limited situations.
For affiliate website owners, the useful comparison is therefore not “Which programme has the biggest percentage?” but “How much commission does a typical completed order actually produce after every programme rule has been applied?”
