Valuation

Discounted cash flow

Convert forecast cash flows and terminal value into a present enterprise or equity value using a discount rate that matches the cash-flow definition and risk.

Quick answer

Discounted cash flow, or DCF, is a valuation method that estimates the present value of expected future cash flows. A firm-value DCF discounts free cash flow to the firm at a weighted average cost of capital and then adjusts enterprise value for debt, cash and other non-operating claims or assets. An equity DCF discounts cash flow to equity at the cost of equity. The forecast, terminal-value method, discount rate and valuation bridge must use consistent definitions.

Meaning and transaction use

Damodaran defines DCF value as the present value of expected cash flows, discounted at a rate that reflects their risk. [S1]

Damodaran distinguishes firm valuation, which discounts cash flows to all capital providers at the cost of capital, from equity valuation, which discounts cash flows to equity at the cost of equity. [S1]

IAS 36 uses discounted expected future cash flows to measure value in use and requires an appropriate discount rate, providing an accounting application of present-value principles. [S2]

Worked example

Illustrative enterprise-value DCF only. Assume FCFF of 4.0, 4.5, 5.0, 5.5 and 6.0 million in years one to five, WACC of 10.0%, perpetual growth of 3.0%, debt of 20.0 million, cash of 3.0 million and 10.0 million shares.

PV of explicit FCFF4.0/1.10 + 4.5/1.10^2 + 5.0/1.10^3 + 5.5/1.10^4 + 6.0/1.10^518.6m
Terminal value at year five6.0 x 1.03 / (10.0% - 3.0%)88.3m
PV of terminal value88.3 / 1.10^554.8m
Enterprise value18.6 + 54.873.4m
Illustrative equity value73.4 + 3.0 cash - 20.0 debt56.4m
Illustrative value per share56.4 / 10.05.64

The illustrative enterprise value is 73.4 million and the simplified equity value is 56.4 million, or 5.64 per share. The result depends on the forecast, terminal assumptions, discount rate and full enterprise-to-equity bridge; it is not an offer price or fairness opinion.

Proposed transaction review process

Define the valuation object

Choose enterprise value or equity value, the valuation date, currency, perimeter and cash-flow definition.

Build the operating forecast

Model revenue, margins, tax, investment and working capital from supportable operating drivers.

Set discount and terminal assumptions

Match the rate to the cash flows and document capital structure, risk inputs, terminal growth or exit assumptions.

Bridge, sensitise and reconcile

Convert to equity value, test key inputs and compare the result with market, transaction and balance-sheet evidence.

Evidence checklist

Historical financials

Audited accounts, management accounts, cash-flow conversion and normalisation support.

Operating forecast

Volume, price, margin, tax, working-capital and capital-expenditure assumptions with owners and evidence dates.

Discount rate

Risk-free rate, market risk premium, beta or asset risk, borrowing cost, tax rate and target capital structure.

Valuation bridge

Debt, cash, leases, pensions, minorities, associates, provisions, options and other claims or non-operating assets.

Decision framework

SituationProposed action
Cash-flow definitions do not match the rateRebuild the valuation on a consistent firm or equity basis before relying on the result.
Terminal value dominates the resultExpand the forecast, test convergence and disclose sensitivity to growth and discount rates.
Forecast support is weakUse scenarios, ranges and explicit evidence gaps rather than a single unsupported point estimate.
The equity bridge is incompleteKeep the conclusion provisional until material claims and non-operating assets are reconciled.

Common errors to check

  • Discounting equity cash flows at WACC or firm cash flows at the cost of equity.
  • Using a perpetual growth rate equal to or above the discount rate.
  • Treating accounting profit as cash flow without investment and working-capital adjustments.
  • Presenting a precise output without sensitivity, bridge reconciliation or source dates.

Review the DCF value bridge

Bring the operating forecast, cash-flow definition, discount-rate support, terminal assumptions and enterprise-to-equity bridge to a valuation review. Test the value drivers and unresolved evidence before using the output in a transaction decision.
