If you sell on the Escape from Tarkov flea market, the price you list is not the money you get. The game charges a listing fee up front, and it can be a lot more than people expect. When I built TarkovAtlas, getting that fee right was the foundation for everything else, because “net after fee” is the number that decides whether a sale or a craft is actually worth your time.
The formula, in words
The fee depends on two values. One is the item’s base value, multiplied by the quantity you are selling. The other is the price you ask. The game compares them on a logarithmic scale. Ask far above the base value and the fee climbs steeply. Ask below it and the fee shrinks, but it never disappears. Two rates supplied by the game’s own data, one for the base value and one for the asking price, set how heavy each part is.
VO = basePrice * count VR = askPrice
Po = log10(VO / VR) Pr = log10(VR / VO)
if VR < VO then Po = Po ^ 1.08
if VR >= VO then Pr = Pr ^ 1.08
fee = VO * Ti * 4 ^ Po + VR * Tr * 4 ^ PrHere Ti and Tr are the two rates from the game data. As a sanity check, the formula reproduces about a 14.5 percent fee on LEDX and about 8.8 percent on a graphics card.
What TarkovAtlas does with it
For every item, TarkovAtlas takes the current flea price, applies this fee, and shows what you net. It also compares that with what traders pay, so each item page opens with a plain answer, like “list on the flea for this much, nets this much after the fee, which is this much more than the trader pays.” The site does not apply the Intelligence Center discount, and it says so on the page.
Three details that change the answer
- Craft tools are not counted as a cost. The hideout gives tools back when a craft finishes, so counting them would make every tool-using recipe look worse than it is.
- Thin markets lie. A flea price is an average of whatever listings were scanned. With one or two listings a single seller can move it by hundreds of percent. The biggest-movers view only counts items with at least 20 live offers, and a separate Thin market view collects the shaky ones.
- Many crafts lose money. When I built it, roughly 142 of 186 crafts were unprofitable at live prices. That is the game, not a bug in the calculator.
How fresh are the prices?
Battlestate does not publish an official flea market API, so every community price site relies on crowdsourced data. I measured the age of the data across every flea-traded item and found a median of about 17 minutes, with the slowest 5 percent still under an hour. If the live refresh ever fails, the site labels its prices as baked instead of passing old numbers off as current.
The figures above are from when I built the site, and the game changes. TarkovAtlas is an unofficial fan project and is not affiliated with Battlestate Games. You can see how it looks in the TarkovAtlas walkthrough.
