Terminal value estimates the value of a business's cash flows beyond an explicit multi-year forecast, and in most discounted cash flow (DCF) models it accounts for the majority of total valuation. This calculator applies the Gordon growth (perpetuity) method to compute terminal value and its present value, and shows how sensitive that number is to your growth and discount rate assumptions.

How the Terminal Value Calculator works

The calculator applies the Gordon growth formula: TV = FCF x (1 + g) / (r - g), where FCF is the final year's free cash flow in your explicit forecast, g is the rate you expect cash flows to grow forever after that, and r is your discount rate (typically WACC). This is the standard textbook formula for valuing a growing perpetuity, first formalized by Gordon and Shapiro (1956) in the context of dividend valuation and widely adopted for free cash flow valuation in corporate finance.

Once terminal value is computed, the calculator discounts it back to today's dollars using PV of TV = TV / (1 + r)^n, where n is the number of years between today and the end of the explicit forecast period. This present value figure is what gets added to the present value of your explicit-period cash flows to arrive at total enterprise value.

Inputs and what they mean

Final Year Cash Flow is the last free cash flow figure from your explicit multi-year forecast — not a historical or current-year number. Growth Rate (g) is the rate you assume that cash flow grows every year forever after; because no company can outgrow the economy indefinitely, most analysts cap this near long-run GDP growth (roughly 2-3% for mature economies), per guidance in Koller, Goedhart & Wessels (2020). Discount Rate (r) is usually your WACC, reflecting the blended required return of your capital providers. Discount Periods (n) is simply how many years stand between today and the final forecast year — it only affects the present value calculation, not the raw terminal value itself.

The input with the outsized effect on the result is the spread between r and g. Because the formula divides by (r - g), a narrow spread magnifies the result dramatically — this is the single most common source of terminal value miscalculation in practice.

Limits and edge cases

The Gordon growth method requires the discount rate to exceed the growth rate (r > g); when it does not, the formula is mathematically undefined, and this calculator will flag the result rather than display a misleading number. The method also assumes a single constant growth rate forever, which does not capture cyclicality, competitive disruption, or a company's eventual maturation into a lower-growth phase — some analysts prefer the exit multiple method (applying a valuation multiple like EV/EBITDA to the final year's metric) as an alternative or cross-check, especially for industries with an active universe of comparable transactions. Because terminal value routinely represents 60-80% of total DCF valuation, any terminal value estimate should be treated as a sensitivity range rather than a single precise number, and cross-checked against at least one alternative method before being relied upon for an investment decision.
