terminal value calculation

What is terminal value in a DCF?

In a discounted cash flow (DCF) model, terminal value is the value of all cash flows that occur after your explicit forecast period. If you only model five or ten years of annual cash flow, you still need a way to represent the remaining life of the business. That “rest of life” component is terminal value.

In most DCF models, terminal value is a major part of enterprise value. It is common for terminal value to represent 50% to 80% of total value, which is why terminal value calculation deserves careful assumptions and sensitivity checks.

Two common terminal value calculation methods

1) Gordon Growth (Perpetuity Growth)

This method assumes the company’s free cash flow grows forever at a stable rate. It is best used when a business is expected to mature into a steady long-term growth profile.

• FCF_N: cash flow in the terminal year
• g: perpetual growth rate
• r: discount rate (often WACC)

2) Exit Multiple

This method estimates terminal value as a market-based multiple of a terminal-year metric such as EBITDA or EBIT. It is useful when comparable company or transaction multiples are reliable and up to date.

Discounting terminal value to present value

No matter which method you use, the terminal value is first calculated at the end of year N. You must then discount it back to today:

A common mistake is to forget this discounting step. Doing so can materially overstate value.

Worked example (Gordon Growth)

Suppose your assumptions are:

• Terminal-year free cash flow: $12,000,000
• Discount rate (WACC): 10%
• Perpetual growth rate: 3%
• Terminal year: year 5

Step 1: Compute terminal value at year 5:

Step 2: Discount back to present:

This present value is the terminal component of your enterprise value. You would add it to the present value of explicit forecast-period cash flows.

How to choose strong assumptions

Perpetual growth rate (g)

• Usually linked to long-run nominal GDP or inflation + real growth.
• In developed markets, many analysts use roughly 2% to 3.5%.
• Growth should almost always be lower than the discount rate.

Discount rate (r)

• Use a consistent WACC framework with your capital structure assumptions.
• Make sure tax rate, beta, risk-free rate, and equity risk premium are current.
• Stress test the model with +/− 1% changes in WACC.

Exit multiple

• Ground your multiple in comparable companies and recent transactions.
• Use a metric that matches your peers (EBITDA vs. EBIT, etc.).
• Avoid mixing cycle-high multiples with cycle-low earnings.

Terminal value sensitivity (illustrative)

Small input changes can cause big valuation swings. The table below highlights why sensitivity analysis is essential:

WACC	Growth (g)	Implied TV / FCF Multiple
9.0%	2.0%	14.6x
10.0%	3.0%	14.7x
11.0%	2.5%	11.7x

Common mistakes to avoid

• Using a perpetual growth rate higher than long-term economic growth.
• Applying an exit multiple that is inconsistent with the company’s future margin profile.
• Forgetting to discount terminal value back to present value.
• Mixing nominal and real rates in the same model.
• Relying on one scenario instead of a sensitivity range.

Practical takeaway

A good terminal value calculation is less about finding one “perfect” number and more about building a reasonable range. Start with defensible base assumptions, run upside/downside scenarios, and compare your implied valuation multiples to market reality.

Use the calculator above to quickly test assumptions, then translate the result into enterprise value, equity value, and per-share value in your complete DCF model.
