The dividend yield or dividend–price ratio of a share is the dividend per share, divided by the price per share. It is also a company's total annual dividend payments divided by its market capitalization, assuming the number of shares is constant. It is often expressed as a percentage. Dividend yield is used to calculate the earning on investment (shares) considering only the returns in the form of total dividends declared by the company during the year. Its reciprocal is the price/dividend ratio.
