In economics, a table showing quantities sellers are willing to offer at different prices is called a supply schedule.
A supply schedule pairs possible prices with corresponding quantities supplied, while holding other relevant conditions constant. It provides the numerical information used to draw a supply curve. In a simple example, a seller might offer 10 units at a low price and 30 units at a higher price.
A market supply schedule combines the quantities supplied by all sellers at each price. Economists can then graph those totals to represent market supply. The schedule may describe an individual firm, a group of firms, or an entire market.
A demand schedule performs the parallel job for buyers. Confusing the two is common: supply concerns sellers’ planned quantities, while demand concerns buyers’ planned purchases.
