The capital asset pricing model (CAPM) is the dominant model for estimating the cost of equity.

Cost of equity is determined through various different models such as the Capital Asset Pricing Model (CAPM), Gordon model and many others. Here is more information on cost of equity https://trignosource.com/Cost%20of%20equity.html
To calculate capital charge, you can use the formula: Capital Charge = Cost of Equity × Equity + Cost of Debt × Debt. Cost of equity is usually estimated using the Capital Asset Pricing Model (CAPM) or Dividend Discount Model (DDM), while cost of debt is based on the interest rate on debt. By multiplying the respective cost by the amount of equity and debt, you can determine the capital charge.
Cost of equity refers to the rate of return that shareholders expect in return for their investment and as compensation for the risk taken by them in investing into that company. So, from the shareholders' point of view, this expected rate of return (cost of equity) would be the opportunity cost of equity, i.e. the rate of return forgone by investing in the company rather than considering alternative investment options. Cost of equity is determined through various different models such as the Capital Asset Pricing Model (CAPM), Gordon model and many others.

The cost of equity using the dividend growth model (DGM) is calculated using the formula: ( r = \frac{D_1}{P_0} + g ), where ( r ) is the cost of equity, ( D_1 ) is the expected dividend next year, ( P_0 ) is the current stock price, and ( g ) is the growth rate of dividends. This model assumes that dividends will grow at a constant rate indefinitely. It is commonly used by investors to assess the expected return on equity investments based on future dividend payments.

An accurate cost accounting system is the basic building block for a good cost estimating system.
An article on cost estimating in the building construction field, admittedly from an out dated source although the principles are still the same, is at http://www.inquirewithin.biz/Vol2/Estimating/estimating_foundations.htm.

Some problem areas in cost of capital analysis include estimating the cost of equity, which can be subjective and sensitive to the choice of models, such as the Capital Asset Pricing Model (CAPM). Additionally, determining the appropriate market risk premium and beta can lead to significant variations in results. The assumptions regarding the debt structure and interest rates can also complicate the analysis, especially in volatile markets. Lastly, the overall capital structure used to weigh the cost of equity and debt may not accurately reflect the firm's actual financing mix.
