How to Calculate The Cost of a Newly Issued Preferred Stock

Convert the flotation cost percent to a decimal by dividing the number by 100. For example, a 5 percent flotation cost divided by 100 would be:
5/100=0.05
Subtract the decimal of the flotation cost from 1. For the example:
1 -- 0.05 = 0.95
Multiply the market price for the preferred stock by one minus the flotation cost. For the example, a market price of $100 would yield:
100x (0.95) = 95.
Divide the dividend paid by the preferred stock by this number. For the example, a dividend for the stock of $5 would result in:
5/95 = 0.053
Multiply this result by 100 to find the cost of the newly issued preferred stock as a percent. For the example:
0.053 x 100 = 5.3 percent.
