How Summer 2019 Cosmetics Collection odds work

With ten Summer 2019 Cosmetics Collection inputs, every next-rarity item shown in the applicable output table has an equal chance. The number of input item names does not change those single-collection odds.

In a mixed contract, each individual input contributes 10% to its collection. Five inputs from this collection therefore assign 50% of the contract to this collection, split evenly among its possible outputs.

Strange and non-Strange items cannot be combined in one contract. Their prices and profitability can differ substantially, so this page calculates them separately.

Market depth, price movement and seller availability are not modeled. Always open the marketplace links and confirm that ten clean, eligible inputs can actually be purchased before trading.
