Setup checklist

Enroll in Brand Registry and the Brand Referral Bonus program in Seller Central.
Create one Amazon Attribution tag per campaign or ad set, named so you can read it later.
Send traffic to your strongest listing or Brand Store page: reviews, images and price ready for cold visitors.
Judge campaigns on Attribution purchases and blended TACoS, not Meta-reported conversions.
Check stock cover before scaling: external traffic that hits a stockout wastes spend and rank.

Planning estimate only. Your bonus is set by Amazon’s program terms.

In short

The Amazon Brand Referral Bonus is a credit Amazon pays Brand Registry sellers on qualifying sales they drive from outside Amazon, measured with Amazon Attribution. Amazon cites an average of 10% of product sales. Counting it changes the real cost of Meta, Google or TikTok ads that send shoppers to Amazon — often enough to turn a campaign that looks unprofitable in Ads Manager into one that pays.

How does this calculator work?

Everything runs in your browser. The formulas:

Clicks = ad spend ÷ CPC. Orders = clicks × click-to-purchase rate.
Attributed sales = orders × average order value.
Bonus = attributed sales × bonus rate. Net ad cost = spend − bonus.
ROAS = sales ÷ spend; effective ROAS = sales ÷ net ad cost.
Profit = sales × profit-before-ads % + bonus − spend.
Break-even CPC = order value × conversion rate × (margin % + bonus %).

Why does Meta under-report Amazon results?

When an ad sends a shopper to Amazon, the sale happens on Amazon’s site, outside Meta’s pixel. Ads Manager records the click and nothing after it, so its ROAS column reads zero for campaigns that may be selling well. Amazon Attribution reports the detail page views, add-to-carts and purchases from each tagged link, which is the number to manage to. We cover the full approach on our Meta ads for Amazon page.

When is external traffic to Amazon worth it?

When the listing converts cold visitors, margins can pay for a click and the bonus is in play. If the break-even conversion rate in the calculator is far above what your listing achieves, fix the listing first — our free listing audit is the fastest place to start.

Frequently asked questions

The Brand Referral Bonus is an Amazon program for sellers enrolled in Brand Registry. When you drive shoppers to Amazon from non-Amazon marketing, such as Meta, Google or email, and measure it with Amazon Attribution, Amazon pays a credit on qualifying attributed sales. Amazon describes the bonus as an average of 10% of product sales; the exact rate varies by category.

You need an active Brand Registry enrollment, you must enroll in the Brand Referral Bonus program in Seller Central, and the traffic must come through Amazon Attribution tags. Sales must happen within Amazon's attribution window and meet the program terms.

On sales. The bonus is a percentage of qualifying attributed product sales, not of your ad spend. That's why conversion rate and order value matter so much in this calculator.

The purchase happens on Amazon, outside Meta's pixel. Meta sees the click, not the order. Amazon Attribution closes that gap by reporting detail page views, add-to-carts and purchases per tagged campaign.

Cold social traffic usually converts well below Amazon search traffic. Start with your own Attribution data if you have it; otherwise test a low and a high case. The calculator's break-even conversion rate shows how high it needs to be.

No. External sales add to sales velocity, which can help organic rank on Amazon, and that extra organic revenue isn't in this model. Treat the result as a conservative view of direct returns.

It is a planning estimate. Your actual bonus rate, attribution window and eligible products come from Amazon's program terms and your Seller Central reports.
