Fill Rate measures how much buyer demand you satisfy immediately from available supply. A high fill rate means buyers find and get what they want on the first try; a low one sends them to competitors. It is a practical liquidity metric for product marketplaces, tying inventory depth directly to whether demand converts or walks away.
Fill Rate
The share of demand met without stockouts or backorders.
