Preferred stocks have a set dividend rate that's based on the "par value" of the stock -- usually $25, but other amounts do exist. In other words, calculating preferred stock dividends is a fairly straightforward process, and you can expect the same dividend amount to continue, quarter after quarter and year after year. Preferred Dividend formula = Par value * Rate of Dividend * Number of Preferred Stocks = $100 * 0.08 * 1000 = $8000. It means that every year, Urusula will get $8000 as dividends. To calculate the dividend amount of a preferred stock, you need two main pieces of information: the par value and preferred dividend rate. As an example, we'll take a look at the JPMorgan Chase preferred stock listed first in the chart -- with a par value of $25 and preferred dividend rate of 6.7%.
