Amazon Affiliate ACoS Calculator
Paste an Amazon product URL, set your creator commission, and see your estimated net affiliate ACoS after Brand Referral Bonus.
What is Amazon affiliate ACoS?
Affiliate ACoS is the percentage of Amazon sales spent on creator, influencer, or affiliate commissions. If a creator drives a $100 Amazon sale and your commission is 20%, the gross affiliate ACoS is 20%.
Amazon brands can have a lower net cost because qualified external traffic may earn Brand Referral Bonus. A 20% creator commission can behave more like a 10% net cost when the product earns an estimated 10% BRB credit.
How is net affiliate ACoS calculated?
The formula is: affiliate commission percentage minus effective Brand Referral Bonus percentage. The calculator also shows the same math in dollars by subtracting the estimated Brand Referral Bonus from the affiliate commission amount.
Affiliate ACoS vs Amazon PPC ACoS
Amazon PPC ACoS measures ad spend divided by attributed sales. Affiliate ACoS measures creator commission cost divided by sales. Affiliate campaigns can be attractive because brands pay for sales, build creator relationships, and may offset eligible sales with Brand Referral Bonus.

Amazon Affiliate ACoS FAQ
What is an Amazon affiliate ACoS calculator?
An Amazon affiliate ACoS calculator estimates the effective cost of paying creators or affiliates for Amazon sales after subtracting eligible Brand Referral Bonus.
How do you calculate net affiliate ACoS?
Net affiliate ACoS is affiliate commission percentage minus the product's effective Brand Referral Bonus percentage. A 20% commission with a 10% BRB creates an estimated 10% net affiliate ACoS.
Why does Brand Referral Bonus lower affiliate ACoS?
Brand Referral Bonus credits eligible sellers for qualified external Amazon traffic, offsetting part of the commission paid to creators or affiliates.
Is affiliate ACoS the same as Amazon PPC ACoS?
No. PPC ACoS measures ad spend divided by sales. Affiliate ACoS measures creator commission cost divided by sales and can be reduced by Brand Referral Bonus.
What affiliate commission should I use?
The calculator defaults to 20% because it is a useful creator commission benchmark, but brands should adjust the rate based on margin, category, and creator quality.
Do I need Amazon Attribution for Brand Referral Bonus?
Sellers generally need Amazon Attribution links so Amazon can identify eligible external traffic and attribute the resulting sale.
Is the ACoS estimate exact?
It is an estimate based on detected product price, category, selected commission, and Amazon's published Brand Referral Bonus rate table.
