yield

Chemical Engineering

The amount of a product that is recovered from a process or chemical reaction. It is usually expressed as a fraction or a percentage based on the raw materials used or as a ratio of the final product to the starting materials without considering any side reactions. The yield coefficient is a measure of the amount of product produced to the raw materials consumed. In a biotechnological process such as fermentation, the yield coefficient is used to express the amount of microbial cells produced per amount of substrate consumed. It is expressed on a weight per weight basis such as kilograms of cells or product produced per kilogram of substrate consumed. The yield coefficient can also apply to the production of a biochemical such as ethanol to the substrate.

Economics

The income from a fixed-interest security as a percentage of its price. The nominal yield is the interest per annum divided by the par value. The running yield is the interest divided by the market price. The yield to maturity is the interest equivalent to the actual interest payments plus capital gains (or minus capital losses) if the security is held to maturity. A yield curve plots the yield on fixed-interest securities against their time to maturity. See also net yield; redemption yield; running yield; sustained yield.
