One way to determine multiple hurdle rates is to use the weighted average cost of capital (WACC) as a baseline, and then adjust it according to the risk and return profiles of different projects. For example, you can use a higher hurdle rate for projects that have higher risk, lower cash flow stability, longer payback periods, or lower strategic value. Conversely, you can use a lower hurdle rate for projects that have lower risk, higher cash flow stability, shorter payback periods, or higher strategic value. Another way to determine multiple hurdle rates is to use the capital asset pricing model (CAPM), which estimates the required return for a project based on its systematic risk, or beta. For example, you can use a higher hurdle rate for projects that have higher beta, meaning they are more sensitive to market fluctuations, and a lower hurdle rate for projects that have lower beta, meaning they are less sensitive to market fluctuations.
