Running Yield

Running yield is a financial metric used to calculate the return generated by an investment, typically a bond or a fixed-income security, based on its current market price and the periodic interest payments it generates. Also known as the flat yield , the running yield offers investors a clear picture of the income potential of their investments, allowing them to make informed decisions in the realm of finance and investing.


The running yield is calculated by dividing the annual interest income generated by an investment by its current market price. It is expressed in percentage terms, providing investors with a standardized measure to compare different securities and assess their relative value. This enables investors, financial analysts, and portfolio managers to assess the income component of an investment and evaluate its potential yield.


To compute the running yield, divide the annual interest income by the bond’s current market price and then multiply the result by 100 to express it as a percentage. The formula can be represented as follows:

Running Yield = (Annual Interest Income / Market Price) x 100


The running yield plays a vital role in understanding the income potential of an investment, particularly for fixed-income securities. It allows investors to evaluate the attractiveness of bonds, debentures, and other similar instruments, solely based on the income they generate.

By analyzing the running yield, investors can assess the relative value of different bonds and make informed decisions on whether to buy, sell, or hold their investments. It helps investors to comprehend the income stream associated with a particular security and estimate the potential returns over time.


While the running yield is a valuable tool for calculating the potential income of an investment, it is important to recognize its limitations. The running yield does not take into account the total return, including any capital gains or losses resulting from changes in the market price of the investment.

Moreover, the running yield assumes that the bond will be held until maturity, disregarding any potential changes in interest rates over time. It is also worth noting that the running yield does not consider the credit risk associated with a bond or security, which can impact the overall return on investment.


Financial professionals and individual investors frequently rely on the running yield as a fundamental measure to assess the performance and attractiveness of fixed-income securities. It provides a quick and simple way to compare investments and determine their income-generating potential.

For example, an investor considering the purchase of a bond can use the running yield to compare the income generated by different bonds with similar features. By calculating and comparing running yields, investors can make more informed investment decisions and select the securities that align with their specific goals and risk tolerance.

In conclusion, running yield is a key metric used within the realm of finance and investing to evaluate the income potential of investments such as bonds and fixed-income securities. By providing a clear measure of the income generated relative to the current market price, the running yield enables investors to make informed decisions and assess the relative attractiveness of different investments.
