CS2 Trade Up Contracts: Full Profit Guide & Float Calculation
TL;DR
- ▸A CS2 trade up contract consumes 10 skins of the same quality to output one skin from the next-higher tier
- ▸Average float of the 10 inputs directly sets the output float — controlling it is the key to profit
- ▸CSBoard indexes ~36,000 skins, letting you source contract inputs at /en/items without paying trading fees
- ▸Top contracts yield 20-40% return when the spread between input cost and expected output value is wide enough
Quick Definition
A trade up contract is a built-in CS2 mechanic. You exchange 10 items of identical quality (e.g., 10 Mil-Spec SMGs) for one item of the next rarity (e.g., one Restricted rifle). The output is randomly selected from the possible outcomes within that collection.
