While a standard financial forecast usually looks three to five years into the future, a business is generally expected to last much longer . Terminal Value (TV) is the tool analysts use to estimate the value of all those "extra" years beyond the forecast period . Because it represents the value of the business into perpetuity, it often makes up the majority of the total valuation . If you get the Terminal Value wrong, your entire valuation will likely be incorrect.

The Perpetual Growth Method (Gordon Growth Model)

The Perpetual Growth Method assumes that the company will continue to generate cash flows and grow at a steady, constant rate forever . This is a favorite of academics because it treats the company like a "perpetuity"—a financial instrument that pays out forever.

The Formula:
$Terminal Value = \frac{FCF \times (1 + g)}{(d - g)}$

FCF = Free Cash Flow of the last forecast period.
g = Terminal growth rate (the "forever" growth rate).
d = Discount rate (usually the WACC).

The "Golden Rule" of the Growth Rate (g)

When choosing a terminal growth rate, you must be conservative. A company cannot grow faster than the overall economy forever; if it did, it would eventually become larger than the entire world's GDP . Therefore, the terminal growth rate is usually set in line with the long-term inflation rate or the historical GDP growth rate, typically between 2% and 4% .

The Exit Multiple Method

The Exit Multiple Method is the preferred approach for many investment professionals and investment banks . It assumes that at the end of the forecast period, the business will be sold to another company or investor . To find the value, you take a financial metric from the final year of your forecast (usually EBITDA) and multiply it by a "multiple" that is common for similar companies in that industry .

The Formula:
$Terminal Value = Final Year Metric \times Exit Multiple$

For example, if a company’s EBITDA in Year 5 is $10 million, and similar companies in that industry usually sell for 8 times EBITDA, the Terminal Value would be $80 million .

Comparing the Two Methods

Both methods have pros and cons, and many analysts calculate both to see if they arrive at a similar number .

Feature	Perpetual Growth Method	Exit Multiple Method
Core Assumption	The business grows at a set rate forever .	The business is sold based on market comps .
Preferred By	Academics and long-term theorists .	Investment bankers and PE firms .
Key Input	Terminal Growth Rate (g) .	Industry Multiple (e.g., EV/EBITDA) .
Risk	Highly sensitive to small changes in 'g' .	Multiples can fluctuate with market cycles .

Step-by-Step Guide: Calculating Terminal Value

Imagine you are valuing a software company with the following data at the end of Year 5:

Year 5 Free Cash Flow: $500,000
Year 5 EBITDA: $800,000
WACC: 10%
Terminal Growth Rate: 3%
Industry Exit Multiple: 12x

Method 1: Perpetual Growth

Take Year 5 FCF ($500,000) and grow it by 3%: $500,000 \times 1.03 = $515,000.
Subtract growth from WACC: $10% - 3% = 7%$ (or 0.07).
Divide: $515,000 / 0.07 = $7,357,143.
Terminal Value = ~$7.36 Million.

Method 2: Exit Multiple

Take Year 5 EBITDA ($800,000).
Multiply by the industry multiple (12).
$800,000 \times 12 = $9,600,000.
Terminal Value = $9.6 Million.

In this case, the Exit Multiple method gives a more optimistic valuation. An analyst might choose to average these two or pick the one that best fits the company's likely future (e.g., is it more likely to stay independent forever or be acquired?).

The Importance of Discounting the Terminal Value

A common mistake for beginners is forgetting that the Terminal Value is the value at the end of the forecast period. If your forecast is 5 years long, that $9.6 million Terminal Value is what the company is worth in Year 5. To find out what it is worth today, you must discount it back to the present using the WACC .

Present Value of TV = $\frac{Terminal Value}{(1 + WACC)^n}$
Using our example: $9,600,000 / (1.10)^5 = $5,960,875.
Even though the company is worth $9.6 million in the future, that "future value" is only worth about $5.96 million to us today.

Frequently Asked Questions about Terminal Value

1. Why does Terminal Value make up so much of the DCF?
Because it represents an infinite number of years, whereas the forecast period only represents a few years .

2. What happens if the Terminal Growth Rate is higher than the WACC?
The formula breaks (you get a negative number). This is why 'g' must always be lower than the discount rate .

3. Can Terminal Value be negative?
Theoretically, if the cost of capital is higher than the growth rate in a way that implies the company is losing value forever, but in practice, a company's value can only fall to zero .

4. Which multiple should I use for the Exit Multiple method?
EV/EBITDA is the most common, but EV/Sales or EV/EBIT are also used depending on the industry .

5. How do I know if my Terminal Value is reasonable?
Check the "implied growth rate." If you used an exit multiple, calculate what growth rate would be required to reach that same value using the perpetuity formula. If the implied growth is 10%, your multiple is likely too high .
