CS2 Trade Up Contract Guide — How to Profit (2026)
Trade Up Contracts are one of the few ways to 'craft' higher-tier skins in CS2. By submitting 10 skins of the same rarity, you receive 1 random skin of the next rarity tier. But the process is far from random — understanding the math behind collection pools, float calculations, and market prices can turn Trade Ups into a consistent profit strategy.
This guide covers everything from the basic mechanics to advanced profitable recipes, with live market data to help you calculate real-time margins.
How Trade Up Contracts Work
Submit exactly 10 skins of the same rarity tier. You receive 1 skin of the next higher tier. The output skin is randomly selected from the collections represented by your 10 input skins. If all 10 inputs are from Collection A, the output will be from Collection A. If 7 are from A and 3 from B, there's a 70% chance of an A output and 30% chance of B.
The Float Calculation Formula
The output float is NOT random. It's calculated as: OutputFloat = (AverageInputFloat × (MaxFloat - MinFloat)) + MinFloat, where MaxFloat and MinFloat are the output skin's float range. This means you can precisely control the output condition by selecting inputs with specific floats. Low-float inputs produce low-float outputs.
Finding Profitable Trade Ups
The key to profitable Trade Ups is finding combinations where the cheapest possible output is worth more than 10× the input cost. Look for collections where: (1) Low-rarity skins are cheap and liquid, (2) The next tier has at least one expensive skin, (3) The collection pool can be manipulated to increase odds of the expensive outcome. Always account for the Steam Market tax (13%) when calculating margins.
StatTrak Trade Ups
StatTrak skins can only be traded up with other StatTrak skins, and the output will also be StatTrak. Since StatTrak versions are rarer and more expensive, StatTrak Trade Ups can be more profitable but require more capital. The same float and collection rules apply.

常见问题与解答
Q:你能从汰换合同中获利吗？
是的，持续获利是可能的。经验丰富的交易者会寻找预期产出价值超过10倍投入成本加手续费的配方。不过，单次汰换仍有概率性——长期多次操作才能稳定盈利。
Q:CS2中最好的汰换合同是什么？
盈利配方随市场价格变化。最佳方法是寻找收藏品中有一件昂贵受限皮肤和数件廉价受限皮肤的军规→受限汰换，然后调整你的10个输入收藏品，最大化产出昂贵皮肤的概率。
Q:你能汰换刀或手套吗？
不能。刀和手套不能用于汰换合同，也无法作为汰换产出。只有编号收藏品中的标准武器皮肤才符合条件。
Q:10个输入皮肤会怎样？
它们会被永久销毁。汰换合同无法撤销。确认前务必仔细检查你的输入。
Q:输入皮肤的顺序重要吗？
不重要。你在汰换界面中放置皮肤的顺序对产出没有影响。只有收藏品分布、稀有度和所有10个输入的平均磨损值才起作用。
