Steam Inventory Checker

Choose a game and paste a steamcommunity.com/id/… or /profiles/… link. The estimate, items and leaderboard refer to the selected game. The inventory must be public; sign-in is not required for the check.

The value is the sum of the lowest available prices across connected marketplaces. Untradable items and items without a price are excluded. This is an estimate before selling fees, not guaranteed sale proceeds.

The check is free and needs no API keys: paste a full profile link, a custom vanity name or a SteamID64.

Once a day we store the inventory value at the lowest available asking prices — those snapshots build the chart. It is a estimate based on asking prices, not what you take home after marketplace fees. While the history accumulates we show the 24-hour, 7-day and 30-day change; next to the value change we show the return, which has deposits removed, so a new knife in the inventory does not inflate it.

The basis is the item price when it first appeared in the inventory snapshot. Steam does not expose trade history, so this is an observation start rather than the purchase price. Adding more of the same item creates a weighted average; when an item leaves, the difference between its basis and last price is recorded as realized profit.
