TF2 inventory value calculator

Every item is matched to its exact variant — the effect on an unusual, the killstreak tier on a weapon, the wear on a war paint — and valued at that variant’s sell price against the current key rate. Metal is counted at what metal is: nine scrap to a refined.

Items we cannot price are counted separately and shown with the reason, rather than being folded into the total at zero. A calculator that quietly rounds the hard parts down is a calculator that tells you your backpack is worth less than it is.

Steam’s public inventory is a display API — it returns the tooltip you would read in-game, not the item’s attributes. Some things simply are not in it: which war paint is on a painted weapon, which spells an item carries, which sheen a killstreak weapon has. Nothing can recover those without a trade offer or an API key.

Sheen and killstreaker have no prices anywhere upstream either — no SKU in the entire pricelist encodes one — so no site can price them honestly.
