As the debt to assets increases from 0% to 100%, the cost of debt financing can be estimated with the following function: 1%+(1/3)(% debt)^2 Use the same function for the cost of equity (change out the %debt for the %equity in the equation) and a tax rate of 30%, with a dividend payout ratio of 60% and an EPS of $2.50. There are no preferred shares. Make a table of debt to assets with the cost of debt, the after tax cost of debt, and the cost of equity (use each 10% level of debt from 10% to 90%). Graph these 3 functions. Set up an equation for the WACC and use the Solver function in Excel to find the minimum cost of capital. At what level of debt is the minimum cost of capital?
