What is Terminal Value?
Terminal value represents the value of a business beyond the detailed forecast period (typically 5-10 years) in a discounted cash flow model. It assumes the company generates cash flows at a stable growth rate in perpetuity. The standard formula is: final year FCF × (1 + perpetual growth rate) / (discount rate - perpetual growth rate). Terminal value typically constitutes 60-80% of total enterprise value.
Why It Dominates Valuation
Even in a 10-year DCF model, the value of all cash flows from year 11 onward usually exceeds the value of the first 10 years combined. This means small changes in terminal value assumptions dramatically affect the valuation. Changing the perpetual growth rate from 2% to 3% can increase terminal value by over 50%. This sensitivity is both the power and the danger of DCF analysis.
Practical Guidelines
The perpetual growth rate should not exceed nominal GDP growth (2-3%), since no single company can outgrow the entire economy forever. Always run sensitivity analysis with optimistic, base, and pessimistic scenarios. If your investment thesis depends heavily on terminal value assumptions, the margin of safety in your purchase price must be correspondingly larger.
