Terminal value questions, answered

Terminal value (TV) is the present value of all expected free cash flows beyond the explicit forecast horizon in a DCF model. It captures the going-concern value of the business after year n of the forecast. In a typical 5-to-10-year DCF for a mature business, TV commonly represents 60 to 80 percent of total enterprise value.

A DCF forecasts cash flows for a finite explicit period (usually 5 to 10 years), but a going-concern business produces cash flows indefinitely. Terminal value compresses everything after the forecast into a single line item. Because the post-forecast period is much longer than the explicit forecast, TV mathematically dominates the enterprise-value total.

Enterprise value is the present value of ALL future free cash flows: the explicit forecast period plus the terminal value. TV is just the post-forecast piece. Enterprise value = sum of discounted explicit-period FCFs + present value of TV.

TV at the end of year n = FCF_n * (1 + g) / (WACC - g), where g is the perpetuity growth rate and WACC is the weighted average cost of capital. To bring TV back to today, divide by (1 + WACC) raised to the power n.

TV at the end of year n = EBITDA_n * (EV / EBITDA)_exit, where the exit multiple is chosen from comparable companies or precedent transactions. The result is discounted to today using (1 + WACC) raised to the power n.

Given TV = FCF * (1+g) / (WACC - g), solve for g: g = (TV * WACC - FCF) / (TV + FCF). If the implied g exceeds 3 to 4 percent, the exit multiple is pricing in permanent above-GDP growth and you should sanity-check the comp set.

The formula is the closed-form sum of a geometric series with common ratio (1+g) / (1+WACC). The series only converges when (1+g) / (1+WACC) < 1, which is equivalent to g < WACC. If g equals or exceeds WACC, the series diverges and terminal value is mathematically infinite.

Long-run nominal GDP growth for the relevant economy is the standard ceiling. For the United States that has historically been 2 to 3 percent. Using g above 3 to 4 percent implies the company outgrows the economy forever, which is mathematically incoherent.

Nominal, to match the nominal free cash flows in the numerator and the nominal WACC in the denominator. If you switch to real terms you must do so consistently across all three inputs.

In order of preference: precedent transaction multiples for comparable M&A deals (best for LBO and strategic-acquisition DCFs), then current trading multiples at public peers, then Damodaran industry medians. Always back-solve the implied perpetuity g as a sanity check.

WACC, the same rate used to discount the explicit-forecast cash flows. The terminal value represents free cash flow to the firm in perpetuity, which is valued at the firm-level cost of capital. For equity-only terminal value (dividend discount model) use cost of equity instead.

M&A practitioners typically lead with the exit multiple method because it anchors to observable transaction or trading multiples. Gordon Growth is computed as a cross-check. Equity research analysts often invert the order, leading with Gordon Growth and using the multiple as the check.

Editorial rule of thumb: within plus or minus 15 percent the methods are consistent. Outside 20 percent you should revisit the inputs. Wider divergences suggest the perpetuity g and the exit multiple are pricing different growth or risk regimes.

Report a range. Best practice is to show TV at the low and high ends of plausible g (or exit multiple) and the corresponding enterprise-value range. A single point estimate hides the model's sensitivity from the reader.

Because the audience is a CEO or board, not an academic. Exit multiples are intuitive (you can name a precedent transaction), Gordon Growth is opaque (you have to defend g). Both belong in the working model; pitch decks usually carry the multiple-driven number with Gordon Growth in the appendix.
