Blox Fruits Trade Calculator

Two questions, two kinds of number

A trade offer raises two separate questions, and most calculators answer only the second one. The first is whether the game will let the trade happen at all: Blox Fruits enforces a price limit inside the trade window, and an offer that breaks it cannot be completed no matter how much both players want it. The second is whether the deal is any good, which is a question about what the community thinks each fruit is worth.

Those two questions run on different numbers. The first uses the price the Blox Fruit Dealer charges — a figure the developers set, the same for every player, published and checkable. The second uses trade values, which the game does not define at all. Mixing them is what produces the familiar situation where a value list says a trade is fair and the trade window refuses to complete it.

The rule the game actually enforces

The trade window compares the total in-game price of the two sides. If they differ by more than 40%, the trade cannot be completed. Four items is the most either side can hold, and trading itself is rate limited — the wiki's Trading page records five trades per eight hours in one place and five a day in another, so treat it as "a few a day" rather than a number to plan around. The price limit is not community opinion, though: it is documented, and you can watch it happen at the table in the Café or the Mansion.

The percentage difference is measured against the heavier side, which is the only reading that makes it a usable limit. Give a fruit priced at 1,000,000 for one priced at 700,000 and the gap is 300,000 against 1,000,000 — thirty per cent, and the window accepts it. Turn it round and measure against the lighter side and you would get forty-three per cent for the same pair of fruits, which would make the same trade both legal and illegal depending on which way you read it.

When a trade is over the limit, the calculator does not stop at "blocked". It works out how much dealer price the lighter side still needs, so you know whether you are one cheap fruit away or nowhere near.

Worked example: a trade the window refuses

Someone offers you their Gas for your Dragon. Dragon costs 15,000,000 from the dealer; Gas costs 3,200,000. The gap is 11,800,000, which against the heavier side is 78.7% — far outside the 40% the window allows, so the trade simply will not go through.

The fix is arithmetic rather than negotiation. The lighter side has to reach 60% of 15,000,000, which is 9,000,000, and it currently sits at 3,200,000. That is 5,800,000 of dealer price to find. Adding Control, which the dealer sells at 9,000,000, takes their side to 12,200,000 and the gap down to 18.7% — comfortably inside the limit. The calculator prints that shortfall for you, so the conversation at the trading table becomes "add something around six million" instead of "it says no".

Why there is no official value list

The wiki puts it plainly on its Trading page: there are no real trading values for the fruits, though every fruit has a money price set by the developers. Everything the trading scene runs on — physical values, permanent values, demand scores, tier lists — is a community estimate. Estimates are not worthless, but they are opinions, and they disagree.

You can see the disagreement without leaving this page. Kitsune and Control sit eleven per cent apart in the dealer's own pricing, at 8,000,000 and 9,000,000. Ask around in trading servers and you will find nobody who treats those two as near-identical. The dealer price is a shop price, set once by the developers; trade value is what another player will actually give up, which is a different thing entirely and moves with every update, event and drop rate change.

So this page ships no value list. Publishing one would mean either inventing numbers or copying somebody else's work, and both make the result worse: a value you cannot check is not a calculation, it is a rumour with a total attached.

Using your own values

Type the value you trade by into the box on each row. Where you get those numbers is your call — the list your trading server keeps, a site you trust, or your own sense of what things move for. What matters is that both sides of one trade are priced from the same source, because a comparison between two different lists is not a comparison at all.

Values are remembered in your own browser, keyed to the fruit and to whether it is physical or permanent, so you type a fruit's value once rather than every time you check a trade. Nothing leaves the device: this page makes no network request of any kind, there is no account, and the clear button empties the lot. If your community revises a value, overwrite it and the new figure is what the next check uses.

The fair band is yours to set too. Five per cent is a reasonable default for ordinary trades, and larger swaps are often settled at ten. Setting it deliberately is better than arguing about whether a three per cent edge counts as a win.

Worked example: a win on your values

Say your community prices your side at 100 and the fruit you are offered at 118. The difference is 18 against the 100 you are giving up, so the trade is 18% in your favour. With the fair band at five per cent that reads as a win; set the band to twenty and the same trade reads as fair. Nothing about the fruits changed — only the threshold you judge them by, which is exactly why the band is on the page rather than hidden in the code.

Both numbers matter together. A trade can be a clear win on values and still be refused by the window, and that combination is common when a cheap-but-wanted fruit is swapped for an expensive-but-unwanted one. The calculator shows both verdicts at once so you find out before you sit down rather than after.

Permanent fruits and game passes

A permanent fruit is bought with Robux and stays on the account, which is why it trades at a different level from the physical version of the same fruit. For the game's price check it behaves differently as well: it is a Robux product rather than dealer stock, and adding one raises the allowed difference well beyond 40%. The wiki records the ceiling as somewhere between 80% and 100%, depending on how valuable the Robux item is.

The exact arithmetic has never been published. Rather than pick a number and present it as certain, this calculator switches to a different answer when a permanent item is involved: it reports the gap, the documented range, and which end of it your trade falls inside. If you are inside the lower figure the window should accept the trade; if you are between the two, it may not.

Mark permanent items with the Form selector on the row. It changes the check, and it keeps your saved values apart, because the permanent and physical versions of a fruit are not worth the same and should never share one number.

Demand, and what it does not tell you

Demand is the trading scene's shorthand for how quickly something moves. A fruit with high demand finds a taker in minutes; a fruit with low demand can sit in your inventory for a week at the same nominal value. It is real information and worth having in front of you.

It is not, however, part of the verdict here. If you fill in the demand boxes the page reports the average for each side so you can see them next to each other, and stops there. Folding demand into a single score would require a weighting this site made up, and a number with an invented coefficient inside it is worse than two honest numbers side by side. Use the value verdict for what the trade is worth, and the demand line for how long it might take to move.

Common mistakes

Reading the dealer price as a trade value. They are different measurements and the gap between them is not consistent from fruit to fruit. The table above tells you what the shop charges, which decides whether the window opens — not what a trade is worth.

Pricing the two sides from different lists. Values from one source and values from another can differ by half, and a verdict built from both is meaningless.

Forgetting the four-item limit. Plans that involve five or six small fruits cannot be traded in one go, whatever the totals say. The calculator flags it.

Treating a permanent and a physical fruit as the same item. One is bought with Robux and is permanent; the other is a consumable. Mark the form on the row.

Limitations

This page checks prices and arithmetic. It cannot tell you whether the other player is honest, whether a fruit is about to be reworked, or whether the person you are trading with will accept anything at all. The trade window itself is the authority on what goes through: if the game refuses a trade this page called allowed, the game is right and something in the inputs does not match what is on the table.

The relaxed limit for Robux items is a documented range rather than a published formula, so trades involving permanents get a range as an answer. Prices change with updates, and the date they were last checked is printed under the table rather than implied.

Finally, nothing here is advice about spending money. Permanent fruits and game passes cost Robux, which costs real currency, and a calculator that says a trade is a win is making a statement about two numbers you typed — not a recommendation to buy anything.
