Why is estimating the growth rate (g) important in DCF?

Estimating the growth rate (g) is crucial in discounted cash flow (DCF) analysis because it directly impacts the projection of future cash flows and the calculation of terminal value. In DCF, future cash flows are forecasted based on expected growth rates. A higher growth rate suggests that the company will generate larger cash flows in the future, leading to a higher overall valuation.

Additionally, when calculating the terminal value—which represents the value of a business beyond the explicit forecast period—the growth rate is a key component. The most common method for estimating terminal value is the Gordon Growth Model, which uses the growth rate along with the discount rate to determine a perpetuity of cash flows. Therefore, if the growth rate is underestimated or overestimated, it can substantially affect the perceived value of a business and influence investment decisions.

While the other choices touch on important concepts in finance, they do not capture the primary reason to focus on growth rates in DCF. The discount rate, cost of equity, and investment limits are influenced by various factors but are not as directly correlated to the estimation of future cash flows and terminal value as the growth rate is. Consequently, the correct answer highlights the vital role of growth estimates in accurately assessing a company’s financial performance and
