Every case returns less than it costs — that gap is Valve's margin. Buying the skin you want on the open market is cheaper than unboxing it, every time. See our case opening ROI guide for the full breakdown.

Your odds over multiple opens

A 0.26% knife chance is hard to picture. This is the same number stated the way it is actually experienced — the chance of at least one, over a run of opens.

100 opens costs $550.00 and returns about $898.78 on average — an expected loss of $348.78.

A coin-flip shot at a knife takes 267 opens — about $1.5Kat this case's price. Even then it is a coin flip, not a guarantee: the odds never carry over between opens. More in our CS2 case odds guide.

CS2 Case Drop Rates

Classified (Pink)3.20%
Covert (Red)0.64%
