How this list is built
The cheapest legal contract, worked through
ShowHide
Ten copies of Tec-9 | Cut Out in Well-Worn at €2.48 each make the cheapest Mil-Spec Grade contract here: €24.80 in, one Restricted skin out. The cheapest Well-Worn copy sits at the worst float of its band, 0.449999, which is 45 percent of the way up that skin's own range, and that position, not the raw float, is what maps into each outcome's range. At that float the outcomes land in Field-Tested to Well-Worn.
Priced at those wears, none of the 5 outcomes we can quote nets more than the €24.80 ticket after the venue's fee. They run from €11.60 to €18.45.
That's the calculator's arithmetic on the cheapest listing, not a pick; price your own ten in the trade-up calculator.
Mixing in other collections

The ten inputs don't have to come from one collection: each input hands its own collection a tenth of the odds. Five Mil-Spec Grade inputs from here and five from The Arms Deal 3 Collection split the contract 50/50, so each of this collection's 5 outcomes drops to 10.00%, and The Arms Deal 3 Collection's 4 outcomes share the other half.
