How is CS2 case ROI calculated?
Every CS2 case has a fixed drop-odds profile published by Valve: 79.92% Mil-Spec, 15.98% Restricted, 3.2% Classified, 0.64% Covert, and 0.26% Rare Special (knives and gloves). Multiply each tier's chance by the average price of the items it contains, apply the wear-distribution math from the item's float range, blend in the flat 10% StatTrak chance on non-glove drops, and you get the expected value per open. Divide that by the container plus key cost and you get ROI. Full tier breakdown on the drop rates page.
Why does this list change every month?
Prices move. Case prices on Steam float with supply (discontinued cases get scarcer, active drops stay cheap), while the skins inside appreciate or depreciate based on meta shifts, tournament rotations, and collection popularity. A case that opens at break-even one month can sit 15% negative the next. This ranking snapshots the best and worst right now; the live rankings update every 15 minutes if you want to check before you buy.
