What Is the Cost of Preferred Stock and Why Does It Matter?

Preferred stock is a hybrid security: it pays a fixed dividend like a bond, but the dividend is paid from after-tax earnings and skipping it does not trigger bankruptcy. The cost of preferred stock is the rate of return investors require to hold the shares, expressed as a percentage. Issuers need the figure because preferred dividends enter the weighted average cost of capital (WACC) as the price of a distinct layer of financing, sitting between debt and common equity.

Because preferred dividends are contractual in amount (though not enforceable like interest), the market prices preferred shares mainly off their dividend stream. The required return therefore behaves like a perpetuity yield: dividend divided by price. The SEC's investor bulletin on preferred securities notes that preferred shares trade on dividend rate, credit quality, and call terms, which is exactly the anatomy of the cost formula covered in the next section.

Three parties care about the number:

• CFOs and treasurers, who compare the after-tax cost of preferred funding against bonds and retained earnings before issuing.
• Corporate investors, whose effective yield is reshaped by the dividends received deduction.
• Valuation analysts, who need the component cost of preferred to weight WACC correctly in discounted cash flow models.

The Formula: Dividend Yield With and Without Flotation Costs

Preferred stock pays a stated dividend indefinitely, so the valuation model is a perpetuity and the required return falls straight out of it:

r_p = D_p / P_0

where D_p is the fixed annual dividend per share and P_0 is the current market price per share. When a new issue is sold, underwriters, legal counsel, and rating agencies take a slice of the offering price, so the issuer nets less than the headline price. With flotation costs F expressed as a fraction, net proceeds are P_0 x (1 - F) and the formula becomes:

r_p = D_p / [P_0 x (1 - F)]

Worked example: straight preferred, then with flotation
A company has preferred shares outstanding on $100 par value carrying a 6% dividend rate, so D_p = 100 x 0.06 = $6.00 per year. The shares trade at $92.50.
Step 1. Without flotation: r_p = 6.00 / 92.50 = 0.064865 = 6.49%.
Step 2. Suppose the firm issues new shares and pays 3% flotation costs. Net proceeds per share = 92.50 x (1 - 0.03) = 92.50 x 0.97 = $89.73.
Step 3. With flotation: r_p = 6.00 / 89.725 = 0.066871 = 6.69%.
Flotation costs add roughly 20 basis points to the cost of the issue, and the gap widens as the dividend yield falls because the fixed costs spread over a thinner yield.

Two consistency checks keep the formula honest. First, D_p is the dollar dividend, not the dividend rate on par; a 6% rate on $50 par is $3.00, not $6.00. Second, use the market price, never par or book value, because investors earn their return on the price they pay.

Worked Examples Across Four Preferred Share Scenarios

The same mechanics produce different costs as dividend, price, and issuance frictions change. The table below runs four scenarios through the formula; each row is a complete calculation an issuer or analyst can reproduce.

Reading the table row by row: the deep discount share pays $8.00 and prices at $110.00, so without flotation its cost is 8.00 / 110.00 = 7.27%. If that company sells new shares and pays 2.5% in flotation, net proceeds fall to 110.00 x 0.975 = $107.25, and the cost rises to 8.00 / 107.25 = 7.46%. Notice that the higher-priced share lost fewer basis points to flotation (19 rather than 20) yet still carries a cost above 7%, because its dividend is richer relative to every dollar raised.

The practical lesson for capital planning: compare issues on net proceeds, not on headline pricing. Two 6% preferred issues at the same par can carry different costs if one sells at $92.50 with 3% flotation and another at $88.00 with 1.5% flotation, since the second nets 88.00 x 0.985 = $86.68 and costs 6.00 / 86.68 = 6.92%, materially more than the first issue's 6.69%.

Cumulative Versus Non-Cumulative Preferred Stock

Cumulative and non-cumulative structures change who bears the risk of a skipped dividend, and therefore what investors demand to hold the paper.

For cost-of-capital purposes, the arithmetic in the perpetuity formula does not change: r_p is still the promised annual dividend divided by price. What changes is the price itself. Cumulative shares from a strong issuer command prices closer to par, pushing yields down; non-cumulative shares from the same issuer trade cheaper to clear the market, pushing the measured cost up. During stress periods the gap can widen sharply, and suspended cumulative dividends accumulate on the balance sheet until cleared.

Analysts should also watch dividend stopper clauses, which prohibit paying common dividends or repurchasing shares while preferred dividends are in arrears. These clauses make cumulative preferred behave more like debt in practice, which is why rating agencies often assign preferred instruments a notch or two of equity credit rather than full equity treatment.

Flotation Costs, Net Proceeds, and Underwriting in Practice

Flotation costs on a preferred offering typically run from 1% to 4% of gross proceeds, composed of underwriting spreads, legal and accounting fees, rating agency charges, and listing expenses. Because the formula divides the fixed dividend by net proceeds, every point of flotation raises the cost of the issue, and the effect is largest for low-yield shares.

Work through the sensitivity. On the $6.00 dividend share priced at $92.50, moving flotation from 1% to 4% walks net proceeds down from $91.575 to $88.80, and the cost up from 6.00 / 91.575 = 6.55% to 6.00 / 88.80 = 6.76%. A 3-point swing in underwriting frictions costs the issuer about 21 basis points per year for the life of the shares, which is permanent money: preferred has no maturity at which the friction is amortized away the way a bond's issuance costs are.

Issuers sometimes recover part of the friction by embedding a call feature and refinancing when rates fall, but the option is not free: investors demand a higher stated yield for callable paper, as covered in the section on redemption features below. Netting flotation against every alternative (a bond issue, a common offering, retained earnings) is the correct comparison, since all channels carry some issuance cost.

The Dividends Received Deduction for Corporate Holders (IRC Section 243)

When the holder of preferred stock is a corporation, the after-tax picture changes through the dividends received deduction (DRD). Under IRC Section 243(a), a domestic corporation receiving dividends from another domestic corporation may exclude a percentage of those dividends from taxable income: 50% where the recipient owns less than 20% of the distributing corporation, and 65% for ownership of 20% or more (below the 80% consolidation threshold). IRS Publication 542 explains the mechanics, including holding-period requirements that deny the deduction on shares held 45 days or less around the ex-dividend date.

The deduction exists to soften the multiple layers of tax on the same earnings. Without it, $1 of profit distributed as a preferred dividend would be taxed once at the issuer and again at the corporate holder, then a third time when the holder's shareholders are paid. The DRD removes half of that second layer for small holdings.

Worked example: after-tax cost to a corporate holder
Step 1. Pre-tax yield on the $6.00 dividend at $92.50 is 6.49%.
Step 2. A corporate holder in the 21% federal bracket excludes 50% of the dividend, so only half is taxable: effective tax on the dividend = 0.50 x 0.21 = 10.5%.
Step 3. After-tax yield = 6.4865% x (1 - 0.105) = 6.4865% x 0.895 = 5.81%.
The same arithmetic on the flotation-adjusted 6.69% issue cost gives 6.69% x 0.895 = 5.99% after tax. For comparison, interest on corporate debt is fully taxable to the recipient (no DRD), so at identical pre-tax yields the preferred route leaves a corporate holder roughly 95 basis points ahead at a 21% rate.

Caveats matter: the DRD does not apply to individual holders, most preferred issued by REITs and RICs pays dividends that fail the deduction, and the holding-period rule punishes dividend capture trades. Corporate treasurers running short-term cash in preferred should confirm eligibility before counting the benefit.

Call Features, Redemption, and Yield to Call

Many preferred issues carry a call option letting the issuer redeem shares at a stated call price, commonly par plus a premium, after a protection period. The call caps the holder's upside: if rates fall, the issuer refinances and returns the call price instead of letting the shares appreciate. Investors charge for that asymmetry, so callable preferred offers a higher current yield than comparable straight shares.

A first-pass measure of return to a call is the approximate yield to call:

YTC = [D_p + (Call Price - P_0) / n] / [(Call Price + P_0) / 2]

Worked example
Step 1. The $6.00 dividend share trades at $92.50 and is callable in 4 years at $105.00.
Step 2. Annual price pull toward the call: (105.00 - 92.50) / 4 = 12.50 / 4 = $3.125.
Step 3. Total annual return component: 6.00 + 3.125 = $9.125.
Step 4. Average investment: (105.00 + 92.50) / 2 = $98.75.
Step 5. YTC = 9.125 / 98.75 = 0.09241 = 9.24%.

The 9.24% yield to call exceeds the 6.49% current yield because the call price sits 13.5% above the market price; the market expects redemption to be unlikely (the shares' 6% coupon is cheap funding for the issuer), so the price trades below par. If instead rates had fallen and the market priced the shares above the call price, yield to call would drop below the current yield and redemption would become the realistic worst case for the holder.

For cost-of-capital work, the issuer should treat the callable yield as the marginal cost of new callable preferred. Skipping the adjustment understates WACC whenever the new issue includes a call feature priced by the market.

Where Preferred Stock Sits in the WACC Hierarchy

In the capital structure, preferred stock ranks behind every creditor and ahead of common shareholders, and its cost lands between the two as well. Three forces set the ordering:

• Tax deductibility. Interest is deductible to the issuer; preferred dividends are paid from after-tax income. At a 21% corporate rate, debt enjoys a 21% subsidy preferred never receives.
• Claim seniority. Preferred holders stand behind bondholders in liquidation, so they bear more risk and demand more return than lenders.
• Obligation flexibility. Skipping a preferred dividend is survivable while defaulting on interest is not, which is why preferred can price inside of high-yield debt for stressed issuers.

Plugging the worked numbers into a WACC: a firm funded with $600 of debt at 5.5% pre-tax (4.35% after tax at 21%), $100 of preferred at 6.69%, and $300 of common equity at 10.5% carries a weighted cost of 0.6 x 4.35% + 0.1 x 6.69% + 0.3 x 10.5% = 2.61% + 0.669% + 3.15% = 6.43%. Preferred's small weight still moved the total, and using the flotation-adjusted 6.69% instead of the unadjusted 6.49% added about 2 basis points of honesty to the discount rate applied to every project the firm evaluates.

The regulatory side reinforces the hierarchy. Under SEC disclosure rules, preferred terms (dividend rate, call schedule, liquidation preference) appear in registration statements and periodic filings, so analysts can extract every input for the cost formula from public documents rather than estimation.
