Dividend Discount Valuation with Declining Dividends

Valuing a Share When Dividends Decline

A company’s dividend need not grow for a dividend discount model to be useful. A firm might be distributing cash while its earnings base contracts, or it might be following a planned policy of reducing its dividend by a stable percentage each year. If the decline is assumed to continue at a constant rate indefinitely, the constant-growth dividend model can still value the share. The important checks are that the dividend forecast remains meaningful and that the required return is high enough for the discounted stream to converge.

Use $D_0$ for the dividend just paid, $D_t$ for the dividend paid at the end of year $t$, $g$ for the annual dividend growth rate, and $r$ for the annual required return on equity. The rates must use the same time unit: in this tutorial, both are effective annual rates. A declining dividend has $g<0$.

Definition: Under a constant-growth dividend assumption, $D_t=D_0(1+g)^t$ for $t=0,1,2,\ldots$. Equivalently, the next dividend is $D_1=D_0(1+g)$, and each later dividend satisfies $D_{t+1}=D_t(1+g)$. When $g<0$, dividends decline by the same percentage each year.

The valuation date matters. A share valued immediately after $D_0$ has been paid is worth the present value of dividends $D_1,D_2,\ldots$, not the present value of a new payment $D_0$. With the usual assumptions of annual payments in arrears, a constant required return $r$, and a dividend path that continues indefinitely, the share price is

P_0=\sum_{t=1}^{\infty}\frac{D_t}{(1+r)^t} =\frac{D_1}{r-g}.

For this formula to describe a positive, indefinitely declining dividend stream, take $D_0>0$, $-1<g<0$, and $r>g$, with $r>-1$ so that the annual discount factor is well-defined. In ordinary equity valuation, $r$ is positive. The condition $g>-1$ keeps every forecast dividend positive; $g=-1$ is a boundary case in which only $D_1$ is positive and all later dividends are zero. A value $g<-1$ would make the forecast dividend negative after the first year, which is not a meaningful path for a continuing positive dividend. The convergence condition $r>g$ is essential, not merely a convenient rule.

Why the Formula Still Works with Negative Growth

The constant-growth formula is the sum of a geometric series. This derivation also shows why negative growth does not invalidate the valuation. Each dividend is multiplied by $1+g$ to reach the next year, while discounting divides by $1+r$. Therefore, the ratio from one discounted dividend to the next is $(1+g)/(1+r)$.

Write the discounted cash flows.
Since $D_t=D_1(1+g)^{t-1}$ for $t\geq1$, the present value of the dividend in year $t$ is $D_1(1+g)^{t-1}/(1+r)^t$.

Factor out the first discounted dividend.
The series begins with $D_1/(1+r)$; each subsequent term is multiplied by $q=(1+g)/(1+r)$. Thus $P_0=[D_1/(1+r)](1+q+q^2+\cdots)$.

Sum the series and simplify.
For $|q|<1$, the infinite geometric series equals $1/(1-q)$. With $r>-1$, $g>-1$, and $r>g$, $0<q<1$, so $P_0=[D_1/(1+r)]/[1-(1+g)/(1+r)]=D_1/(r-g)$.

In the declining-dividend case, $r-g$ is larger than $r$, because $g$ is negative. That larger denominator is appropriate: the next dividend is expected to fall in later years rather than remain level. It would be a mistake to treat a negative growth rate as a negative dividend or to replace $D_1$ with $D_0$. The growth rate changes the forecast path; it does not change the sign of a positive dividend when $-1<g<0$.

Worked Example: Value a Share with a 4% Annual Dividend Decline

A hypothetical company has just paid a dividend of $5.00 per share. Its dividend is expected to decline by 4% per year indefinitely, and investors require a 9% annual return. Find the value immediately after the dividend has been paid. Also check the first forecast dividends and the implied return components.

Method. First calculate the next dividend from $D_0$, then apply the constant-growth model. This avoids the common mistake of treating the dividend just paid as the next dividend.

The growth rate is $g=-0.04$, so the multiplier from one year to the next is $1+g=0.96$. Therefore,

D_1=5.00(0.96)=\$4.80,\qquad D_2=4.80(0.96)=\$4.608,\qquad D_3=4.608(0.96)=\$4.42368.

The required return is $r=0.09$, and $r-g=0.09-(-0.04)=0.13$. The share value is

P_0=\frac{4.80}{0.13}=\$36.9230769\ldots

Rounded to the nearest cent, $P_0=\$36.92$. The dividend yield using the unrounded price is $D_1/P_0=4.80/(4.80/0.13)=0.13$, or 13%. Adding the growth rate gives $13\%+(-4\%)=9\%$, the required return. The computed dividends are positive and decline by the same 4% at each step, while $r>g$, so the model’s path and convergence checks are satisfied.

Common mistake avoided: Using $D_0$ in the numerator would give $5.00/0.13=\$38.46$ after rounding. That overstates value because the $5.00 dividend has already been paid; the first cash flow available to the new shareholder is $D_1=\$4.80$.

Checking the Required-Return Relationship

The valuation equation can also be rearranged to reveal how the share’s expected return is composed. Starting from $P_0=D_1/(r-g)$, multiply both sides by $r-g$, divide by $P_0$, and isolate $r$:

P_0(r-g)=D_1 \quad\Longrightarrow\quad r-g=\frac{D_1}{P_0} \quad\Longrightarrow\quad r=\frac{D_1}{P_0}+g.

Here $D_1/P_0$ is the forward dividend yield. When dividends decline, $g<0$, so the expected dividend yield must exceed the required return for the equation to balance. The yield compensates for the expected reduction in the dividend. This is an algebraic implication of the model, not a claim that the share’s realized return in any particular year is guaranteed to equal $r$.

Worked Example: Infer the Required Return from a Declining Dividend

A hypothetical share is priced at $30.00 immediately after a dividend payment. The next annual dividend is forecast to be $2.70, and dividends are expected to decline by 2.5% per year thereafter. Find the required return implied by the price, then verify the valuation.

Method. Use the rearranged return relationship, keeping the negative growth rate signed. The common error is to subtract the magnitude of the decline twice.

The forward dividend yield is

\frac{D_1}{P_0}=\frac{2.70}{30.00}=0.09=9\%.

The growth rate is $g=-0.025=-2.5\%$. Thus the implied required return is

r=0.09+(-0.025)=0.065=6.5\%.

To verify, the second dividend is $D_2=2.70(0.975)=\$2.6325$, and the model value using the inferred return is

\frac{D_1}{r-g} =\frac{2.70}{0.065-(-0.025)} =\frac{2.70}{0.09} =\$30.00.

The implied return is 6.5%, not 11.5%: the signed growth contribution is negative, so it is added as $-2.5\%$ to the 9% yield. The check reproduces the observed price, and $r>g$, as required.

How the Rate of Decline Affects Value

Holding the required return and current dividend fixed, a faster decline generally lowers value for two reasons: it reduces the next dividend and increases the gap $r-g$. The numerator and denominator both matter. Comparing only the denominators can miss part of the change, especially when the current dividend rather than the next dividend is supplied.

Annual dividend growth rate	Next dividend from $D_0=\$6.00$	Denominator when $r=10\%$	Share value
$-2\%$	$\$6.00(0.98)=\$5.88$	$0.10-(-0.02)=0.12$	$\$5.88/0.12=\$49.00$
$-6\%$	$\$6.00(0.94)=\$5.64$	$0.10-(-0.06)=0.16$	$\$5.64/0.16=\$35.25$

Worked Example: Compare Two Declining-Dividend Forecasts

A hypothetical share has just paid a $6.00 dividend. The required annual return is 10%. Management is considering two indefinitely maintained dividend policies: a 2% annual decline or a 6% annual decline. Calculate both share values and determine the percentage by which the faster-decline value is below the slower-decline value.

Method. For each policy, calculate $D_1=D_0(1+g)$ and then use $P_0=D_1/(r-g)$. The method avoids applying the same numerator to both scenarios when the current dividend is the common input.

For the 2% decline, $g=-0.02$, so

D_1=6.00(0.98)=\$5.88,\qquad r-g=0.10-(-0.02)=0.12,\qquad P_0=\frac{5.88}{0.12}=\$49.00.

For the 6% decline, $g=-0.06$, so

D_1=6.00(0.94)=\$5.64,\qquad r-g=0.10-(-0.06)=0.16,\qquad P_0=\frac{5.64}{0.16}=\$35.25.

The absolute reduction in value is $\$49.00-\$35.25=\$13.75$. Relative to the slower-decline value, the percentage reduction is

\frac{13.75}{49.00}\times100\%=28.0612\ldots\%.

Rounded to two decimal places, the faster-decline value is 28.06% lower. Both paths remain positive because their growth rates exceed $-100\%$, and both satisfy $r>g$. The comparison checks both the lower next dividend and the larger denominator under the faster decline.

Conditions and Common Exam Traps

A constant negative growth rate describes a specific forecast: the same percentage reduction repeats every year forever. It does not mean that the dividend falls by a fixed dollar amount. For example, a 5% decline from $10 is $0.50 in the first year, but a subsequent 5% decline is 5% of the smaller dividend, not another $0.50. The compounding definition $D_t=D_0(1+g)^t$ captures that distinction.

Use the next dividend in the numerator. If the stated amount is the dividend just paid, first multiply by $1+g$. If the problem already gives next year’s dividend, use it directly.
Keep the decline signed. A 3% decline means $g=-0.03$. The denominator is $r-g=r+0.03$, not $r-0.03$.
Match periods. An annual dividend growth rate must be paired with an annual required return. Do not combine a monthly decline with an annual return without converting the rates and cash-flow timing consistently.
Check the path and convergence separately. For a positive dividend that remains positive, use $g>-1$; for the present-value series to converge under the usual discounting assumptions, require $r>g$.
Interpret yield and growth together. The model implies $r=D_1/P_0+g$. With $g<0$, the forward yield exceeds $r$; adding a positive decline magnitude to the yield would reverse the sign incorrectly.

Key takeaway: For a positive dividend declining at a constant rate, value the share as $P_0=D_1/(r-g)$, using $D_1=D_0(1+g)$ when the dividend just paid is given. Confirm that the forecast dividends remain meaningful and that $r>g$; then check that the forward yield plus the signed growth rate equals the required return.
