In short
The Amazon Brand Referral Bonus is a credit Amazon applies against your referral fees on sales from traffic you send from outside Amazon, such as Meta ads, Google, email or influencers. Amazon says it averages 10% of qualifying sales, and it also counts other products from your brand that the shopper buys within 14 days of the click. Only traffic through an Amazon Attribution tag qualifies, and the brand has to be in Brand Registry with a Professional selling plan in Amazon's US store. Multiply Attribution sales by your category's bonus rate: $8,000 at 10% is $800. Take the bonus off your ad spend to get an effective ROAS, and compare that with your break-even. Plan for it as lower fees, not cash. The bonus pays on attributed sales, not on proven incremental sales.
What is the Amazon Brand Referral Bonus?
The Brand Referral Bonus is money Amazon gives back when you send shoppers to Amazon from outside it: Meta ads, Google, email, influencers. Amazon says the bonus averages 10% of qualifying sales. It also counts other products from your brand that the shopper buys within 14 days of the click.
It isn't paid as cash. Amazon applies it as a credit against your referral fees, so it lowers what Amazon charges you on sales. To qualify, the traffic has to come through an Amazon Attribution tag, which is how Amazon knows the shopper came from your ad.
Who can use it: sellers with a Professional selling plan whose brand is enrolled in Amazon Brand Registry, selling in Amazon's US store, with a Brand Representative role for the brand.
How to calculate the Brand Referral Bonus
bonus = Amazon Attribution sales × bonus rate effective ad cost = ad spend − bonus ROAS = Amazon Attribution sales ÷ ad spend effective ROAS = Amazon Attribution sales ÷ effective ad cost ROAS uplift = ad spend ÷ effective ad cost − 1
- Amazon Attribution sales: Amazon sales credited to your tagged ads over the period. These are the sales the bonus is paid on.
- Bonus rate: the bonus as a share of those sales. It depends on your category. Amazon's examples include about 11% for clothing, and 10% for furniture on the part of the price up to $200 and 7% above that.
- Ad spend: what you spent on the tagged ads over the same period.
Worked example
A made-up supplement brand spends $4,000 on Meta ads in a month, all linking to its Amazon listing with Attribution tags. Amazon Attribution credits $8,000 of sales. These are the example values in the calculator.
- Bonus: $8,000 × 10% = $800.
- Effective ad cost: $4,000 − $800 = $3,200.
- ROAS before the bonus: $8,000 ÷ $4,000 = 2.00.
- Effective ROAS: $8,000 ÷ $3,200 = 2.50.
- ROAS uplift: $4,000 ÷ $3,200 − 1 = 25%.
A 10% bonus lifted ROAS by 25%, not 10%. That's because the bonus is a share of sales, and sales here are twice the spend.
What's a good effective ROAS?
The same answer as for any ROAS: anything above your break-even ROAS. Work yours out with the break-even ROAS calculator. What the bonus changes is how much it helps. The higher your ROAS, the bigger the boost, because the bonus grows with sales while spend stays put. At a 10% bonus rate:
| ROAS before bonus | Effective ROAS | Uplift |
|---|---|---|
| 1.00 | 1.11 | 11% |
| 2.00 | 2.50 | 25% |
| 3.00 | 4.29 | 43% |
| 4.00 | 6.67 | 67% |
| 5.00 | 10.00 | 100% |
The ranges shift with your category's bonus rate, and with your margin, which sets the break-even line. A bonus that turns a 2.0 ROAS into 2.5 matters most if you break even at 2.3: it moves the ads from losing money to making it. At a break-even of 1.5 they were already profitable; at 4 they still lose money, just less.
Common mistakes
- Untagged links. Only traffic through an Amazon Attribution tag earns the bonus. A Meta ad pointing at a plain Amazon URL earns nothing.
- Treating the bonus as cash. It's a credit on referral fees. Plan for it as lower fees, not money in the bank.
- Assuming a bonus means the ads work. The bonus pays on attributed sales, whether or not the ads caused them. It's real money either way, but it doesn't tell you whether the sales are extra.
- Using the wrong rate. 10% is Amazon's average, not your rate. Check your category.
- Mismatched periods. Attribution counts purchases up to 14 days after the click. Leave time after the period ends before you pull the sales.
How this connects to true incrementality
The bonus is paid on Amazon Attribution sales, and those aren't the same as incremental sales. Some tagged buyers would have bought anyway. Many shoppers who saw your Meta ad and searched Amazon later never clicked a tag, so they're not in Attribution and earn no bonus, but they're still sales your ads caused.
So use the bonus to lower your ad cost, then judge the ads on what they really added. iROAS divides those caused sales by spend; marketing incrementality is the same idea in dollars. The attribution gap calculator shows how far Amazon Attribution is from measured incremental sales, and the halo effect calculator shows the sales it misses. For how to measure them, see incrementality measurement, or size a test with the holdout test calculator.
Frequently asked questions
How much is the Amazon Brand Referral Bonus?
Amazon says it averages 10% of qualifying sales. Your rate depends on the product category. Amazon's examples include about 11% for clothing, and for furniture about 10% on the part of the price up to $200 and 7% above that. Check Seller Central for your category.
Who is eligible for the Brand Referral Bonus?
Sellers with a Professional selling plan whose brand is enrolled in Amazon Brand Registry, selling in Amazon's US store, with a Brand Representative role for the brand. Untagged traffic doesn't qualify.
Do Meta (Facebook and Instagram) ads qualify?
Yes, if each ad links to your Amazon listing or Brand Store through an Amazon Attribution tag. A plain amazon.com URL earns no bonus. Amazon lists social media among the traffic sources that qualify.
How is the Brand Referral Bonus paid?
As a credit against your referral fees, not as cash in your bank account. Plan for lower fees on those sales, not money you can withdraw.
Does the bonus count other products the shopper buys?
Yes. It also covers purchases of other products from your brand made within 14 days of the click on your tagged link.
Does the Brand Referral Bonus mean my ads are incremental?
No. The bonus pays on Amazon Attribution sales. Those can include buyers who would have ordered anyway, and they miss shoppers who saw a Meta ad and searched Amazon later. Measure incremental sales with a holdout test, not with the bonus alone.
