Use a financial website, like Morningstar or Yahoo Finance (see Resources below), to get information on the dividend amount and the required rate of return for the preferred shares. If you manage your preferred shares in an online investment account, you can also get these details from your account.
Convert the required rate of return from a percentage into a number with a decimal point. For example, if the required rate of return is 8.5 percent, it would convert to 0.085.
Calculate the market value of your preferred shares by dividing the dividend amount by the required rate of return. The formula is "market value = dividend/ required rate of return." The amount that you get will be the value per share of your preferred shares.
