CS2 knife trade up calculator

Since Valve's 22 October 2025 update you can put five Covert skins into the Trade Up Contract. Five regular Covert skins return one regular knife or one pair of gloves; five StatTrak Covert skins return one StatTrak knife. In both cases the result comes from a collection of one of the skins you put in, so the cases your inputs belong to decide which knives and gloves are possible.

Yes. Valve's patch notes say five StatTrak Covert items can be exchanged for one StatTrak knife. StatTrak gloves do not exist, so a StatTrak contract never returns gloves, and a StatTrak Covert from a gloves-only case has no knife pool in this calculator.

Covert weapon skins from a case whose special-item pool holds knives or gloves. In the data behind this page that is 81 Covert skins across 43 cases. Covert skins that only exist in souvenir collections, such as the AWP | Dragon Lore, have no knife pool in the item data and are not listed. Valve has not published what happens if you use one, so check in-game before buying inputs.

Valve has not published them. The patch notes only say the result comes from a collection of one of the inputs. The model used here, the same one the ten-skin contract uses, is that each input is one vote for its case (five from one case lock the result to that case) and each item in the case is equally likely. Treat the chances as a model, not a guarantee.

Valve has not published a float rule for the five-Covert contract either. The model used here is the ten-skin rule: each input's float is placed inside its own skin's range, the five results are averaged, and the average is mapped onto the knife's own range. Because Doppler, Fade and similar finishes are capped at 0.08, they land in Factory New or Minimal Wear almost whatever you put in.

By cost of five inputs on 10 November 2026, the cheapest single-case contract is five AWP | Chrome Cannon (Well-Worn) from the Kilowatt Case at about $115.00. The model gives an average result of $64.72 for it, with 13 possible results. The table on this page lists the cheapest contract for every case.

Not on average. On 10 November 2026, 1 of the 43 cases have a five-of-the-cheapest contract whose modelled average result is above its cost, before Steam fees and with results priced at the lowest listing. The rest lose money on average: the case's pool includes many cheap finishes, so the average result is pulled down. A contract that returns a knife worth less than you paid is the common outcome.

Yes, with regular Covert skins. Gloves are in the pool of 8 cases; 8 of them (Glove Case, Operation Hydra Case, Clutch Case, Operation Broken Fang Case, Snakebite Case, Recoil Case, Revolution Case, Sealed Dead Hand Terminal) hold only gloves, so five Covert skins from one of those always return gloves.
