Trade-Up Simulator
This is a free CS2 trade-up simulator and contract calculator. Choose your input skins, see all possible outputs, hit chances, and profit or loss based on live market prices. Designed for Counter-Strike 2 players who want to plan trade-ups before risking their skins in-game.
Step 1 - Search skins
Only valid trade-up skins are shown (no knives/gloves/etc). Click a card to add it to your contract.
Step 2 – Validate contract inputs
Pick skins from the left. The first skin locks the contract grade (e.g. Mil-Spec, Restricted, Covert).
Step 3 – Review output pool
Auto-generated from your inputs (next grade in the same collections). You can tweak it manually later.
Profit / ROI
This is auto-filled from market prices of your input skins (if available). Edit it if you paid a different amount.
All CS2 Collections & Knives
Live database loaded from the ByMykel CS2 API. Search skins or collections. Knives are marked with a ★ badge.
