Your Amazon Buy Box percentage is the share of page views where your offer occupied the Buy Box, meaning the Add to Cart button belonged to you. Amazon now calls it the Featured Offer. It matters more than almost any other single number, because the overwhelming majority of Amazon orders go through that button rather than through the other-sellers list.
That’s changed. Amazon now publishes what decides it: total price including shipping, the delivery promise, free shipping, free returns, and seller performance. It also says what doesn’t count: reviews, Prime eligibility and whether you use FBA or ship yourself. Price gets all the attention. It isn’t the whole answer, and that’s exactly why cutting price so often fails to win the box back for sellers who assumed it would.
Where to find your percentage
In Seller Central, open Business Reports and look for the Featured Offer (Buy Box) percentage at the ASIN level. Amazon defines it as the number of page views in which your offer was featured, divided by the total page views for your products. Set the date range wide enough to see a trend rather than a day.
I’d check this weekly on any product with competing offers. It moves before your sales do, so a falling percentage is an early warning, and in our experience sellers notice the revenue drop first and then spend a week working out what happened.
If your ranking has already moved, Buy Box is the second thing to check after stock. Our guide on diagnosing a ranking drop runs the full sequence in the order worth checking.
Reading the report properly
The Buy Box percentage column is easy to misread, and two mistakes are common enough to warrant naming.
The first is reading it at account level. The account figure averages across everything you sell, so a catalog of uncontested private label products masks a serious problem on the handful of ASINs where you compete. I’d only ever read this at ASIN level, sorted by revenue, because that is where the money actually is.
The second is reading a single day. Buy Box share rotates. When two offers are closely matched Amazon shares the box between them, so a day at 40% and a day at 60% can be the same underlying situation. Look at two weeks and read the trend, not the point.
There is a third thing the report will not tell you, and it is the one that matters most. It shows that you lost the box. It does not show who won it or why. For that you have to open the listing yourself and read the competing offers: their price, their shipping cost, their return terms and the delivery date each one shows.
I’d do that manually on your top three competed products rather than trying to automate it. Five minutes each, once a week. In our experience the cause is usually obvious the moment you look at the actual page, and completely invisible from the report alone.
One more habit worth building. When you find the reason, write it down with the date. Buy Box losses repeat, and a short history tells you whether this is the same competitor returning or a new problem, which changes the response entirely.
What “Buy Box wins” actually means
Sellers talk about “Buy Box wins”. Amazon doesn’t. There’s no report metric by that name, but three things come close:
| Where | What it shows |
|---|---|
| Business Reports | Your Featured Offer (Buy Box) percentage: featured page views divided by total page views |
| Selling Partner API offer data | Whether an offer is currently in the Buy Box; Amazon says there can be up to two winners per ASIN at once, one Prime-eligible and one not |
| Featured Offer Expected Price (API) | The price at or below which Amazon expects your offer could become the Featured Offer, with no guarantee because competing offers change |
Rotation is normal. When offers are closely matched, Amazon says the Featured Offer can rotate between them, which is why your percentage sits between 0 and 100 rather than being all or nothing.
A September 2026 change. Amazon says that as of September 2026 it no longer maintains a seller eligibility requirement: offers from all sellers are now evaluated for the Featured Offer. That’s a real shift. Being considered isn’t winning, though. Not even close. An offer that isn’t competitive won’t be picked, and Amazon may feature no offer at all if none meets its customer-experience standards.
The factors Amazon says decide the Featured Offer
| Factor | What Amazon says | What to do about it |
|---|---|---|
| Total price | Item price plus shipping; coupons and promotions help | Compare your landed price against each competing offer, not your item price alone |
| Delivery promise | Faster, more specific delivery is preferred | Check the delivery date buyers see on your offer versus theirs |
| Free shipping | A $40 offer with free shipping is preferred to $35 plus $5 shipping | Build shipping into the price where you can |
| Free returns | Counts in your favor | Offer free returns if your margin allows |
| Seller performance | Order volume (with steps so smaller sellers aren’t disadvantaged), chargeback rate, and customer complaint types | Keep complaints and chargebacks low |
| In stock and shippable | Out-of-stock offers can’t be featured | No stock, no Buy Box. There is no partial credit |
What Amazon says it ignores: customer reviews and ratings, whether the offer is Prime-eligible, and whether it’s FBA or seller-fulfilled. That surprises people. If everything else is equal, FBA and FBM offers are “equally likely” to be featured. Amazon also says it ranks offers the same way for every product and never uses manual overrides.
Total price is the one people get wrong, and I’ve seen it cost real margin. Amazon compares price plus shipping, so a seller at $24 with free delivery beats you at $22 plus $4 shipping. If you are losing the Buy Box while apparently being cheapest, check this first.
Delivery is where FBA still matters, indirectly. Speed wins. FBA isn’t a factor in itself, but FBA offers usually show fast, free delivery, and those are factors. If you ship yourself, match the delivery promise and the free shipping, and Amazon says your offer is as likely to win as an FBA one. Our guide to FBM shipping requirements covers what that takes. If you ship from your own warehouse, that means a handling time you can genuinely keep every single day, a carrier service fast enough to show a delivery date that matches the FBA offers on the same page, and shipping costs built into your item price rather than added at checkout, because the buyer only ever compares the total and the date. Then hold it.
Why cutting price often fails
This is the mistake I’d most want to prevent. It costs margin and fixes nothing.
If you lost the Buy Box to an offer with faster or free delivery, price may not be the binding constraint. You can undercut it and still lose, because the delivery promise is doing the work. You have then given away margin and gained nothing.
Same for seller performance. If complaints or chargebacks are dragging your offer down, lowering the price just makes the eventual recovery more expensive.
So before touching price, answer one question: what changed? If a competitor arrived, price may be relevant. If your delivery promise slipped, your performance dropped, or you were briefly out of stock, price is irrelevant and you should fix the actual cause.
I’ve found that single question saves more margin than any repricing strategy.
Repricers, and how to use one without harm
A repricer adjusts your price automatically against competing offers, and in our experience it is the tool most often configured badly. On a catalog with many competed ASINs it is close to essential, because manual repricing does not scale.
Two rules I’d treat as non-negotiable.
Set a floor and mean it. The floor should be your genuine break-even including every fee, not a number that feels low. Repricers race to the floor, and an inaccurate floor produces sales that lose money reliably.
Do not chase unauthorized sellers to the bottom. If someone selling counterfeit or gray-market stock is undercutting everyone, matching them is a losing fight. Report it and hold your price.
Beyond that, prefer a rule that targets the Buy Box rather than the lowest price. Winning at a penny below the next offer is the goal; being cheapest on the page is not, and those are different settings.
When nobody has the Buy Box
Sometimes the Add to Cart button is missing entirely and the page shows only “See All Buying Options.” This is worth recognizing because the causes are specific.
It happens more than you’d think. Amazon says it may show no Featured Offer when none of the offers meets its customer-experience requirements, even if yours is the only offer. In our experience the most common reason is price: offers well above what the product usually sells for. Sometimes it means the product is restricted, or the listing has a problem.
The fix, when it is pricing, is to bring your price to something Amazon considers reasonable. If you use the Selling Partner API, the Featured Offer Expected Price tells you the level Amazon has in mind. Annoying, but fixable. This is frustrating when your costs genuinely justify a higher price, and I’d rather say plainly that there is not always a way around it.
What to actually do this week
Work in this order. I’d go cheapest first every time.
- Check stock, including any gap in the last 90 days.
- Check Account Health and confirm every metric is inside target.
- Compare landed price, yours plus shipping against each competing offer plus theirs.
- Compare the delivery date shown on your offer against theirs. Not your handling time, the date the buyer sees.
- Check shipping and return terms. Free shipping and free returns both count in Amazon’s selection.
- Only then consider price.
Steps one to five take twenty minutes and identify the cause most of the time. Step six is where most sellers begin, which is why so many of them end up cheaper and still losing.
The longer game
I’d treat Buy Box share on a competed ASIN as a permanent contest rather than a problem you solve once.
Two things compound in your favor. Order volume is part of seller performance, so steady selling helps over time, and Amazon says it takes steps so smaller sellers aren’t disadvantaged. And low complaint and chargeback rates keep your offer competitive during the moments that matter.
The third thing, and the strongest, is not competing at all. A product only you sell has no Buy Box contest, which is one of several reasons private label is worth the additional risk. Our guide to finding low competition products covers how to choose one that stays uncontested for a while.
FAQ
What is Amazon Buy Box percentage?
The share of your product’s page views where your offer was the Featured Offer, meaning the Add to Cart button was yours. Amazon calculates it as featured page views divided by total page views, in Business Reports at ASIN level.
What does Buy Box wins mean?
There’s no Amazon metric called “Buy Box wins”. Sellers use it for how often their offer is featured, which Amazon reports as the Featured Offer percentage. Through the API, Amazon also flags whether an offer is currently the Buy Box winner; there can be one Prime and one non-Prime winner per ASIN.
What determines who wins the Amazon Buy Box?
Amazon lists total price including shipping, the delivery promise, free shipping, free returns and seller performance, and the offer must be in stock. It says reviews, Prime eligibility and FBA versus FBM are not considered.
Why am I losing the Buy Box even though I have the lowest price?
Usually because Amazon compares price plus shipping rather than price alone, or because a competing offer has a faster delivery promise, free shipping or free returns, or because complaints or chargebacks are hurting your seller performance.
Does FBA help win the Buy Box?
Not directly. Amazon says FBA and seller-fulfilled offers are equally likely to win if everything else is equal. FBA helps indirectly, because FBA offers usually show fast, free delivery, and the delivery promise and free shipping are factors.
Should I use a repricer?
On a catalog with many competed listings, yes, since manual repricing does not scale. Set the floor at genuine break-even including all fees, and configure it to target the Buy Box rather than the lowest price on the page, which are different settings.
Why does no one have the Buy Box on my listing?
Amazon says it may feature no offer when none meets its customer-experience requirements, even with a single offer. High pricing is the usual cause in our experience; restricted products and listing problems are others.
Last updated: October 18, 2026. Amazon now publishes the factors it uses to choose the Featured Offer, though not their exact weights, so the advice here follows Amazon’s page plus observed behavior. An earlier version of this page treated FBA and selling history as ranking factors; Amazon’s current page says fulfillment method is not considered, and the page has been corrected.
