Discounted Cash Flow Valuation of a Business: FCFF, WACC and Terminal Value
Every CAIIB candidate preparing Advanced Business and Financial Management eventually meets the same exam favourite: discounted cash flow valuation of a business. Whether a bank's credit team is appraising a large corporate borrower, a merchant banking desk is pricing an IPO, or a treasury analyst is deciding whether to invest in a subsidiary, the DCF method converts a company's future free cash flows into today's rupees. This article walks through the three moving parts examiners love to test together — Free Cash Flow to Firm (FCFF), the Weighted Average Cost of Capital (WACC), and Terminal Value — and closes with a fully solved numerical so you can practise the full chain end to end.
💰 What FCFF Means and Why Bankers Must Know It
Free Cash Flow to the Firm (FCFF) is the cash generated by a business's core operations that is available to all capital providers — lenders and shareholders alike — before any financing decisions are made. The standard build-up starts from EBIT: FCFF = EBIT × (1 − tax rate) + Depreciation & Amortisation − Capital Expenditure − Increase in Net Working Capital. Because interest is added back (via the after-tax EBIT starting point) rather than deducted, FCFF is unaffected by how the firm is financed, which is exactly why it is discounted at WACC rather than the cost of equity alone.
For a bank's credit and investment functions this distinction matters enormously. A term-lending officer appraising a highly leveraged infrastructure borrower wants a capital-structure-neutral view of the underlying business before layering on the actual debt schedule; FCFF gives that view, while FCFE (Free Cash Flow to Equity) already bakes in the borrower's specific debt. Good FCFF forecasting is really an extension of sound corporate planning — unrealistic revenue or margin assumptions in the plan flow straight through to an inflated valuation, which is precisely the trap examiners build into numerical questions.
⚖️ Building the WACC: Cost of Equity and Cost of Debt
WACC blends the return demanded by every capital provider, weighted by the market value each contributes to total capital. Cost of equity is usually estimated using CAPM: Ke = Rf + β(Rm − Rf), where Rf is a risk-free proxy such as the 10-year G-Sec yield, β measures the stock's volatility relative to the market, and (Rm − Rf) is the equity risk premium. Cost of debt is the yield the firm currently pays lenders, adjusted downward for the tax shield: Kd(1 − t). The two are then combined as WACC = We × Ke + Wd × Kd(1 − t), where We and Wd are the market-value weights of equity and debt respectively.
Executing this calculation correctly and consistently is itself a management discipline — it feeds into how a bank's treasury directing function sets internal hurdle rates for project appraisal, and how those hurdle rates are enforced across business units. A WACC that is set too low approves marginal projects; one set too high rejects value-accretive ones, so CAIIB questions frequently test whether candidates can correctly identify which weights and which tax rate to plug in.
💡 Exam Tip: CAIIB numericals almost always expect market value weights for equity and debt in the WACC formula, not the book values printed in the balance sheet — using book weights is the single most common reason candidates pick the wrong option.
📈 Terminal Value: Capturing Cash Flows Beyond the Forecast Horizon
No analyst can forecast cash flows forever, so a DCF model splits the future into an explicit forecast period (commonly 5 to 10 years) and everything after it, captured in a single number called Terminal Value (TV). The most common approach is the Gordon growth (perpetuity) method: TV at the end of the explicit period = FCFF of the final forecast year × (1 + g) ÷ (WACC − g), where g is a modest, sustainable long-run growth rate. An alternative is the exit-multiple method, which applies a comparable-company EV/EBITDA multiple to the final year's EBITDA instead of assuming perpetual growth.
The Gordon growth formula only works mathematically, and only makes economic sense, when g is strictly less than WACC and is set close to the long-run nominal growth rate of the economy — never close to the historical growth of the specific company, which is unsustainable forever. Because terminal value routinely contributes the majority of total enterprise value in a DCF model, examiners like to test whether candidates notice an unrealistic g.
⚠️ Common Mistake: Picking a terminal growth rate above the economy's long-run nominal GDP growth rate breaks the WACC greater-than-g condition and produces an unrealistically high, sometimes even negative, enterprise value.
🧮 Worked Example: From FCFF to Enterprise Value
Assume a company's FCFF for Year 1 is Rs 100 crore, growing at 8% a year for a 5-year explicit forecast, after which cash flows grow at a stable 5% forever. The capital structure is 70% equity and 30% debt; cost of equity is 14%, pre-tax cost of debt is 9%, and the tax rate is 25%.
Step 1 — WACC: After-tax cost of debt = 9% × (1 − 0.25) = 6.75%. WACC = (0.70 × 14%) + (0.30 × 6.75%) = 9.80% + 2.03% = 11.83%.
Step 2 — Explicit FCFF and present values (discount factor = 1 ÷ 1.1183^n): Year 1: Rs 100.00 cr, PV Rs 89.42 cr. Year 2: Rs 108.00 cr, PV Rs 86.36 cr. Year 3: Rs 116.64 cr, PV Rs 83.41 cr. Year 4: Rs 125.97 cr, PV Rs 80.55 cr. Year 5: Rs 136.05 cr, PV Rs 77.79 cr. Sum of PVs of explicit FCFF ≈ Rs 417.53 crore.
Step 3 — Terminal Value at end of Year 5: TV = FCFF5 × (1 + g) ÷ (WACC − g) = 136.05 × 1.05 ÷ (0.1183 − 0.05) = 142.85 ÷ 0.0683 ≈ Rs 2,091 crore. Discounting this back 5 years at the same 11.83%: PV of TV = 2,091 × 0.5717 ≈ Rs 1,196 crore.
Step 4 — Enterprise Value: EV = PV of explicit FCFF + PV of Terminal Value = 417.53 + 1,195.7 ≈ Rs 1,613 crore. To reach equity value for shareholders, a valuer would further subtract net debt (total borrowings less cash and cash equivalents) from this Rs 1,613 crore enterprise value.
📌 Remember: Enterprise Value values the whole firm; subtract net debt and add non-operating cash to reach the equity value applicable to shareholders.
🏦 Where DCF Fits in a Bank's Credit and Investment Decisions
DCF is not an academic exercise for exam halls alone — it is embedded in real banking workflows. Project and infrastructure finance teams use it to test debt-servicing capacity of a borrower over the loan tenure, building on the appraisal techniques covered in our guide to project finance appraisal techniques. Under India's insolvency framework, registered valuers preparing fair-value and liquidation-value estimates for a resolution plan under the Companies (Registered Valuers and Valuation) Rules, notified by the Insolvency and Bankruptcy Board of India, are expected to consider the income approach (DCF) alongside market and asset approaches, and to disclose the basis relied upon.
A robust valuation also depends on how well a bank's own controlling function monitors actual cash flows against the projections fed into the model — large, unexplained variances between forecast and actual FCFF are exactly the red flag credit-monitoring teams are trained to escalate. Candidates who have already worked through our companion guides on free cash flow to firm and risk analysis in capital budgeting will find the WACC and terminal-value mechanics here build directly on that foundation, and pair naturally with the risk-weighting concepts in countercyclical capital buffer from the Risk Management elective.
| Feature | FCFF Approach | FCFE Approach |

| Output of the model | Enterprise Value | Equity Value directly |
| Needs a separate debt-to-equity adjustment? | ✓ Yes (subtract net debt) | ✗ No |
| Sensitive to changing leverage over the forecast? | ✗ Less sensitive | ✓ Highly sensitive |
| Preferred when capital structure is unstable | ✓ Yes | ✗ No |
🧠 Practice MCQs: Discounted Cash Flow Valuation of a Business
Q1. In the FCFF approach to valuation, which adjustment is made to after-tax operating profit (EBIT(1-t)) to arrive at free cash flow to the firm? (a) Subtract interest expense after tax (b) Add back depreciation, then subtract capital expenditure and the increase in net working capital (c) Add back capital expenditure and subtract depreciation (d) Subtract dividends paid to equity shareholders
Answer: (b) — FCFF adds back non-cash depreciation and deducts capex and the increase in working capital from after-tax EBIT; interest is excluded because FCFF is a pre-financing cash flow.
Q2. While computing WACC for a listed company, the weights assigned to equity and debt should ideally be based on: (a) Book values shown in the latest balance sheet (b) Market values of equity and debt (c) The face value of shares issued (d) Historical cost of assets
Answer: (b) — Market values reflect current investor expectations and the true opportunity cost of capital, so WACC weights should use market values rather than book values.
Q3. In the Gordon growth (perpetuity) method of estimating terminal value, which condition must hold for the formula to give a meaningful result? (a) The growth rate must equal WACC (b) The growth rate must exceed WACC (c) The growth rate must be less than WACC (d) WACC must be less than the cost of debt
Answer: (c) — The perpetuity formula FCFF(1+g) divided by (WACC minus g) is valid only when the terminal growth rate g is strictly less than WACC; otherwise the denominator turns zero or negative.
Q4. Enterprise Value obtained from a DCF model is converted into the value of equity available to shareholders by: (a) Adding total debt to enterprise value (b) Subtracting net debt (total debt minus cash and equivalents) from enterprise value (c) Multiplying enterprise value by the tax rate (d) Dividing enterprise value by the number of outstanding shares directly, without any adjustment
Answer: (b) — Equity value equals enterprise value minus net debt, since enterprise value represents claims of both lenders and shareholders while equity value belongs only to shareholders.
Q5. A firm's FCFF in year 5 of the explicit forecast is Rs 100 crore and is expected to grow at 5 percent per year forever thereafter. If the WACC is 12 percent, the terminal value at the end of year 5 is closest to: (a) Rs 1,500 crore (b) Rs 1,400 crore (c) Rs 1,250 crore (d) Rs 2,000 crore
Answer: (a) — Terminal value equals FCFF times (1 plus g) divided by (WACC minus g): 100 times 1.05 divided by 0.07 equals approximately Rs 1,500 crore.

❓ Frequently Asked Questions
What is the difference between FCFF and FCFE?
FCFF (Free Cash Flow to Firm) is the cash available to all capital providers — both lenders and shareholders — before financing effects, while FCFE (Free Cash Flow to Equity) is the cash left for equity shareholders alone after interest and debt repayments. FCFF is discounted at WACC to get enterprise value; FCFE is discounted at the cost of equity to get equity value directly.
Why is WACC used as the discount rate for FCFF?
Because FCFF represents cash flow available to both debt and equity holders, it must be discounted at a rate that reflects the blended required return of both groups of capital providers, which is exactly what the Weighted Average Cost of Capital measures.
Can terminal value form a very large share of total enterprise value?
Yes. In most DCF models terminal value often accounts for 60 to 80 percent of the total enterprise value because it captures all cash flows beyond the explicit forecast period into perpetuity, which is why examiners test the terminal growth assumption closely.
Is DCF the only method used to value a business under Indian valuation norms?
No. Registered valuers typically triangulate DCF (the income approach) with the market approach (comparable companies or transactions) and the asset approach, and disclose in their report which method they principally relied upon.
Mastering the FCFF-to-WACC-to-terminal-value-to-enterprise-value chain is one of the highest-yield investments a CAIIB ABFM candidate can make, since the same three building blocks reappear across project appraisal, M&A and resolution-plan questions.
