What is a “DCF sensitivity test” used for?

A DCF sensitivity test is utilized to understand how sensitive the valuation derived from a discounted cash flow (DCF) analysis is to changes in key assumptions. In a typical DCF model, various inputs such as revenue growth rates, discount rates, and terminal value assumptions play crucial roles in determining the value of an investment. By systematically varying these assumptions within a sensible range, the sensitivity test reveals how much the calculated present value of future cash flows fluctuates based on those changes.

This analysis is essential for investors and analysts because it helps to identify which assumptions have the most significant impact on the valuation. For instance, if slight changes in the discount rate lead to substantial variations in the DCF value, it indicates a high sensitivity to that particular assumption. Understanding this sensitivity allows for better risk assessment and strategic decision-making when it comes to investment opportunities. This is particularly relevant in industries or companies with volatile cash flows or uncertain future performance.
