How much will a stack of skins or cases fetch?

The page multiplies the best one-unit quote by your quantity three ways: instant cash from the highest bid, listing at the lowest ask on markets with enough listings, and Steam wallet funds after Steam’s 13% fee. These are upper bounds from one-unit quotes, not guarantees for the whole quantity.

Listing pays more but waits for buyers, and many buyers undercut by a few cents when a lot of volume is listed. Instant offers avoid that but pay less. The gap between the two is shown as the cost of selling now instead of waiting.

The page compares your quantity with the copies Steam sold in the last 24 hours. The result reads, for example, “your copies are about two days of its sales”. Steam pays in wallet funds, which cannot be withdrawn as cash.

A market with fewer than 10 listings is a thin venue: one ask on two listings is not a price you can count on, so it is left out of the listing figure and named instead. The “would add” column shows your quantity as a share of the listings already there.

No. No marketplace publishes units absorbed per price, so the price for the 10th copy is unknown. Use the one-unit bid as the first unit’s price, expect less for the rest, and split a large stack across markets.
