Terminal Growth Rate & Terminal Value Calculator

Method 1: Calculate Growth Rate (Fundamental Approach)

Estimate the long-term growth rate based on company fundamentals: Growth = Reinvestment Rate × ROIC

Method 2: Calculate Terminal Value (Gordon Growth)

Calculate the total value of all future cash flows beyond the projection period.

Understanding Terminal Growth Rate in DCF Analysis

The Terminal Growth Rate is the constant rate at which a company's free cash flow (FCF) is expected to grow indefinitely after the initial forecast period. In a Discounted Cash Flow (DCF) model, since we cannot project cash flows forever, we use this rate to determine the "Terminal Value" of the business at the end of the projection horizon.

How to Calculate Terminal Growth Rate: Two Approaches

1. The Fundamental Approach

This method derives growth from how much the company reinvests and the return it earns on that capital. The formula is:

Terminal Growth Rate = Reinvestment Rate × Return on Invested Capital (ROIC)

Example: If a company reinvests 20% of its earnings and has an ROIC of 15%, the implied growth rate is 3% (0.20 * 0.15).

2. The Perpetual Growth Approach (Gordon Growth)

Most analysts use a rate that aligns with the long-term growth of the economy (typically the risk-free rate or GDP growth). This is usually between 2% and 3% for mature companies. Once you have this rate, you calculate the Terminal Value (TV) using the Gordon Growth Model:

TV = [FCFn × (1 + g)] / (WACC – g)
  • FCFn: Free Cash Flow in the final year of the projection.
  • g: Terminal Growth Rate.
  • WACC: Weighted Average Cost of Capital (Discount Rate).

Critical Rules for Setting the Growth Rate

When selecting your terminal growth rate, keep these guidelines in mind:

  • The GDP Limit: The terminal growth rate cannot exceed the long-term growth rate of the economy (GDP). If a company grows faster than the economy forever, it would eventually become larger than the economy itself.
  • Inflation: Usually, the rate is at least equal to the expected long-term inflation rate.
  • WACC Relationship: The growth rate (g) MUST be less than the WACC. If g > WACC, the formula results in a negative or infinite value, which is mathematically impossible for valuation.

Practical Example

Imagine a tech company with a final year FCF of $5,000,000. Your WACC is 8%, and you assume a long-term terminal growth rate of 2%.

  1. Numerator: $5,000,000 × (1 + 0.02) = $5,100,000
  2. Denominator: 0.08 – 0.02 = 0.06
  3. Terminal Value: $5,100,000 / 0.06 = $85,000,000

This $85 million represents the value of all cash flows from Year 6 into infinity, which you then discount back to the present value to complete your DCF model.
