However, comparing cost of capital and expected returns is not always straightforward, as there are many factors that can affect both variables, such as risk, uncertainty, inflation, taxes, and market conditions. Therefore, you need to adjust your cost of capital and expected returns to account for these factors and ensure that you are making realistic and consistent comparisons. One way to adjust your cost of capital is to use the capital asset pricing model (CAPM), which estimates the cost of equity based on the risk-free rate, the market risk premium, and the beta coefficient of your business. The risk-free rate is the return that you can earn on a riskless investment, such as a government bond. The market risk premium is the difference between the return that you can earn on the market portfolio, which represents the average return of all risky investments, and the risk-free rate. The beta coefficient measures the sensitivity of your business to the market movements, and indicates how much riskier or safer your business is compared to the market average. The higher the beta, the higher the cost of equity, and vice versa. To adjust your expected returns, you can use techniques such as scenario analysis, sensitivity analysis, or Monte Carlo simulation, which allow you to estimate the range and probability of different outcomes based on various assumptions and variables.
