Direct answer
The dividend discount model (DDM) values common equity as the present value of dividends expected to be received by common shareholders:
P0 = sum of expected future dividends discounted to today
For a dividend that grows forever at a constant rate, the Gordon Growth Model is:
P0 = D1 / (r - g)
Here, D1 is the expected common dividend per share over the next period, r is the cost of common equity, and g is the sustainable perpetual growth rate. The formula requires r > g.
DDM is most informative when a company pays meaningful common dividends under a reasonably predictable policy. A multistage model is usually more credible when near-term growth or payout differs from the mature-state assumption.
How the model works
DDM discounts equity distributions, so it uses a cost of equity rather than WACC. It is a per-share model when the inputs are dividends per share; forecasts must therefore reflect expected issuance, option dilution, conversions, and repurchases that change the future share count.
The constant-growth formula uses the next dividend, not the dividend just paid:
D1 = D0 x (1 + g)
A multistage DDM forecasts individual dividends during an explicit period and then estimates a stable terminal value:
P0 = D1/(1+r)^1 + D2/(1+r)^2 + ... + [Dn+1/(r-g)]/(1+r)^n
Growth must be supported by earnings, cash generation, capital requirements, leverage, regulation, and reinvestment economics. One diagnostic, under stable return-on-equity and payout assumptions, is:
sustainable growth = retention ratio x return on equity
This is a cross-check, not a law. Accounting ROE can be distorted, new equity can fund growth, buybacks alter per-share figures, and future returns on retained capital may differ from historical ROE.
Regular common dividends should be separated from special dividends, preferred dividends, stock dividends, and return-of-capital distributions. A special cash dividend can be valued separately if expected; it should not be grown forever by default.
DDM can understate the economic payout of companies that return most cash through repurchases. A total-payout or free-cash-flow model may be more informative, but buybacks cannot simply be added to dividends without reconciling share-count effects and financing.
Worked two-stage example
Assume a company just paid a regular common dividend of US$1.50 per share. Dividends are expected to grow 10.00% annually for three years, then 4.00% perpetually. The illustrative cost of equity is 9.00%.
The explicit dividends are:
D1 = US$1.50 x 1.10 = US$1.65
D2 = US$1.65 x 1.10 = US$1.8150
D3 = US$1.8150 x 1.10 = US$1.9965
The first stable-period dividend is:
D4 = US$1.9965 x 1.04 = US$2.07636
The Gordon terminal value at the end of year 3 is:
P3 = US$2.07636 / (9.00% - 4.00%) = US$41.5272
The present value of the first three dividends is:
US$1.65/1.09 + US$1.8150/1.09^2 + US$1.9965/1.09^3 = US$4.5831
The present value of the terminal value is:
US$41.5272 / 1.09^3 = US$32.0666
The illustrative value is therefore:
US$4.5831 + US$32.0666 = US$36.6497 per share
Terminal value contributes 87.49% of the result. If only the stable growth rate falls from 4.00% to 3.00%, value falls to US$31.0483. If only the cost of equity rises from 9.00% to 10.00%, value falls to US$30.5000.
These sensitivities do not identify the correct value. They show how much of the conclusion depends on assumptions that must be defended.
Review checklist and model risks
- Confirm that the forecast is for common dividends per share, after any preferred claim, rather than total company distributions.
- Distinguish the last paid dividend
D0from the next expected dividendD1. - Reconcile historical regular, special, stock, and return-of-capital distributions instead of treating them as one recurring series.
- Tie dividends to the statement of changes in equity, cash-flow statement, footnotes, and subsequent declarations.
- Review board discretion, legal capital rules, debt covenants, regulatory capital, liquidity, and other distribution constraints.
- Compare dividends with earnings, free cash flow, cash balances, borrowing, asset sales, and new share issuance.
- Normalize payout ratios for unusual earnings, losses, impairments, gains, and cyclical peaks or troughs.
- Assess whether dividend smoothing causes payout growth to lag changes in sustainable earnings.
- Model expected share issuance, employee awards, conversions, and repurchases when forecasting dividends per share.
- Separate dividend growth driven by operating progress from growth created by a shrinking share denominator.
- Use a cost of common equity consistent with currency, inflation, geography, and risk embedded in the dividend scenarios.
- Make high-growth and transition periods explicit rather than applying a temporary growth rate forever.
- Require the stable growth rate to remain below the cost of equity and sustainable in the relevant economy.
- Cross-check stable growth against reinvestment needs, retention, incremental returns, market maturity, and competitive conditions.
- Do not assume historical ROE will persist when leverage, margins, asset intensity, or accounting equity changes.
- Value an expected special dividend separately instead of capitalizing it as a perpetuity.
- Compare dividend-based value with total-payout and FCFE approaches when repurchases are economically significant.
- Quantify how much value comes from the explicit dividends and terminal component.
- Run two-dimensional cost-of-equity and growth sensitivities, plus dividend-cut and payout-transition scenarios.
- Compare estimated value with market price only after checking dates, currency, share class, taxes, and transaction costs.
Common misconceptions
- “DDM value is the same as dividend yield.” Yield divides a current or indicated dividend by market price; DDM discounts a forecast stream to estimate value.
- “A stock that pays no dividend has zero economic value.” A practical DDM needs expected eventual distributions, but other equity models can value reinvestment, future payouts, or sale proceeds when dividends are absent today.
- “Higher payout always creates higher value.” Paying more can reduce valuable reinvestment, weaken liquidity, increase financing needs, or make future dividends less sustainable.
- “Historical dividend growth can continue forever.” Mature growth must converge to an economically defensible rate below the required return.
- “Buybacks and dividends are interchangeable inputs.” Both return capital, but repurchases change shares outstanding and per-share claims, so a total-payout model requires a careful share-count bridge.
