Yield On Cost (YOC) is a metric used to calculate the annual return on an investment based on the original cost of the investment, rather than the current market value.To calculate YOC, the current yield of an investment is divided by the original cost of the investment and then multiplied by 100 to express the result as a percentage. The formula for YOC is:YOC = (Annual dividend / Original Cost of Investment) * 100For example, if an investor bought a stock for $100 and the current annual dividend is $5, the YOC would be 5% ($5 / $100 * 100).YOC is used as a measure of the performance of an investment over time and can be useful in evaluating the potential long-term return of an investment.However, it's important to keep in mind that YOC can be misleading, as it does not take into account changes in the market value of the investment, dividends, or other factors that may affect the return on investment.Additionally, YOC is typically used for income-generating investments, such as dividend-paying stocks or bonds, and may not be applicable to other types of investments, such as growth stocks or real estate.
