Year Yield refers to the total return on an investment over a specified period, typically expressed as an annual percentage rate. It is calculated by taking into account any interest, dividends or capital gains earned on the investment during that timeframe and compounding it to express the overall return in terms of an annual rate. Year yield can be used interchangeably with other similar measures such as total return, annualized return, and current yield, depending on the context in which it is being calculated. It provides a useful measure for comparing different investments or evaluating the performance of a single investment over time.
