A card's floor price is the delivered price of the single cheapest fixed-price listing you could actually buy right now, item cost plus required shipping. It counts only live Buy It Now-style listings, never auction results, and it drops any listing whose shipping cost is unknown rather than guessing at one.
In the market, it moves for one of four reasons: that cheapest listing sold, it vanished without selling, its seller repriced it, or a new, cheaper listing showed up.
What floor price actually measures
A floor answers a narrow question: what would it cost, delivered, to buy one copy of this exact card and condition on the open market at this moment. It is not an average, not a prediction, and not a target.
That narrowness is deliberate. A card can have plenty of recent sales at higher prices while its floor sits low, because one seller is currently willing to let a copy go cheap. The floor tracks that seller, not the crowd.
It also is not the same thing as a trailing sold-price average. A rising average of recent sales and a flat, or even falling, floor can happen at the same time, because an average looks backward at what already sold while a floor looks at what is buyable this second. Confusing the two is a common way to misread "the price" of a card.
How the calculation works
The mechanics run in a fixed order every time:
Build the ladder. Every active, fixed-price listing for the exact card, printing, condition, and grade (if graded) is gathered and ranked from cheapest to most expensive.
Price it delivered, not sticker. eBay always shows the shipping cost separately from the item cost, so a buyer can see exactly what delivery will cost before checkout (eBay, accessed September 27, 2026). Adding the two together, item plus required shipping, gives the delivered figure that gets ranked.
Drop what cannot be priced delivered. A listing with unclear or missing shipping is excluded from the calculation entirely. It is never assumed to ship free.
Exclude auctions completely. eBay's own fixed-price Buy It Now listings let a buyer pay a set price and finish immediately, while its auction-style listings start at a seller-chosen price and only sell to whoever is the highest bidder when the auction ends (eBay, accessed September 27, 2026). Those are two different markets, and an auction result never feeds into a fixed-price floor.
Drop asks that have not been reconfirmed. A listing counts only if it has been seen live recently, within a window tied to how often that marketplace is re-checked for the card. An ask nobody has reconfirmed may already be gone, so it does not set the floor.
Hold back implausible prices. An ask priced implausibly far below the card's own reference price, such as what it has recently traded at, is kept off the floor; that is typically a mislabeled or different item. It stays visible as a listing; it just does not get to define the price.
Take the cheapest survivor. The floor is simply the lowest delivered price left after the steps above, even when only one listing survives. If none survives, no floor is shown.
A worked, hypothetical example, not a real listing: four fixed-price copies of a card sit delivered at $20, $22, $25, and $31. The floor is $20.
If that copy sells, the floor becomes $22, whether or not anyone relists. If a new seller instead lists a copy at $18, the floor drops to $18 even though nothing sold at all.
Floor price versus other card-page numbers
Collectors run into several differently defined figures for the same card, and treating them as interchangeable produces bad comparisons.

A single auction, never a fixed-price floor
Each row answers a different question. A floor can sit well under a recent sold median if a seller is simply willing to let a copy go for less than the market has been paying, and an auction result on a scarce grade says nothing about where the next raw copy would sell on a fixed-price listing.
Four reasons a floor price moves
Four market events change a floor, and none of them is "the market feels different."
It sold. The cheapest listing gets bought. Unless a new one appears at the same or a lower delivered price, the floor steps up to the next rung on the ladder.
It vanished without selling. A listing can disappear because the seller relisted it, pulled it to bundle with other cards, or corrected an error. None of that is a sale, and Cardboard Alpha's own methodology never counts a vanished listing as one; a copy that disappears without a confirmed transaction stays an unconfirmed sale candidate until something corroborates it, not evidence of a completed sale at any price.
It got repriced. A seller can lower or raise an ask with no sale attached to the move. The floor still moves, but it reflects a seller's changed opinion, not confirmed demand clearing supply.
A cheaper one showed up. A new seller lists below the current floor. The floor drops immediately, even though the prior cheapest listing is still sitting there unsold.
Only the first case reflects real demand clearing real supply. Yet on a floor chart a sale and a delisting look like the same step up, and a price cut and a new cheaper listing look like the same step down, while meaning very different things underneath. Reading the full ask ladder rather than just the top listing is the only way to tell them apart.
When there is no floor price yet
A card can end up with no qualifying listing at all: nothing is offered at a fixed price, every ask is missing its shipping cost, or no ask has been reconfirmed recently enough to trust. Rather than keep showing a price that may no longer exist, Cardboard Alpha's methodology leaves the floor empty in that case.
Each printing and condition is its own book. A famous card such as Base Set Charizard splits into separate floors for its different printings and conditions, so one version can have a deep ladder while another has one ask or none. That is also where a floor is most jumpy: with a single live listing, that listing selling, vanishing or being repriced moves the whole number, and the floor is honest about it rather than smoothing it.
As soon as a fresh, delivered-priced ask is observed again, the floor returns on the same rules as any other card. Nothing about the calculation changes; only the evidence behind it does.
What a floor price is not
A floor is a snapshot of the cheapest deliverable buy-in-hand at one moment, not a forecast and not a signal to act on. It says nothing about where a card is headed, and it is not evidence that a card is undervalued or overvalued.
It is most useful for like-for-like comparisons: this card's floor against its own history, or one card's floor against another's, both read the same way. Screening for cards where the floor itself is behaving in a specific way, thinning, rising, or holding steady across a window, is a starting point for research, never a standalone buy or sell instruction.
Collectors who want to see this mechanic applied across the covered catalog can screen for floor behavior directly rather than checking one card page at a time.
Frequently asked questions
What does "floor price" mean for a Pokemon card?
Floor price is the delivered price, item cost plus required shipping, of the single cheapest live fixed-price listing for a specific card and condition. It excludes auction results and any listing whose shipping cost cannot be determined.
Is floor price the same as a sold-price average?
No. A sold-price average looks backward at recent confirmed transactions, while a floor looks at what is buyable this second. The two can move in opposite directions at the same time, and neither substitutes for the other.
Why did a card's floor price change overnight?
Four market events move it: the cheapest listing sold, it was pulled or relisted without a sale, its seller repriced it, or a new, cheaper listing appeared. A floor chart alone cannot tell you which one happened; the underlying listings can.
Does floor price include shipping?
Yes. Floor price is always a delivered figure, item price plus required shipping. A listing with unknown or unclear shipping is excluded from the calculation rather than treated as free to ship.
Can an auction result set the floor price?
No. Auctions and fixed-price listings are separate markets with different mechanics: a fixed-price listing sells to the first buyer who accepts the ask, while an auction sells to the highest bidder only when it ends. A winning auction bid never feeds into a fixed-price floor calculation.
What does it mean when a card shows no floor price at all?
It means no listing currently qualifies: there is no live fixed-price ask with known shipping that has been reconfirmed recently enough to count. Rather than show a price that may no longer exist, the floor stays empty until a fresh, delivered-priced ask is observed again.
