Trade-Up Calculator (Lite)

Pick up to 10 skins of the same rarity to estimate a CS2 trade-up contract outcome. A full trade-up radar (collection-aware +EV contracts) is not shipped — item collections live in metadata only, not as a queryable rarity graph in the DB.

1. Search for input skins

Add up to 10 skins — real contracts require the same rarity tier.

3. Estimated outcome

Add skins above to see an estimate.

Quick start: search for one inexpensive Mil-Spec skin, add ten inputs from the same rarity tier, then compare the estimated Restricted output before buying anything.

Lite estimate — not float-accurate. The real output float depends on the destination collection's float range, not a simple average of input floats. Find low-float inputs on CSFloat
