Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round intermediate calculations.) High-Low method - Calculation of Variable Cost per unit Change in cost Cost at high point minus cost at low point 0 Change in volume Cost at low point minus cost at high point High-Low method - Calculation of Fixed Costs Total cost at the high point Variable costs at the high point: Volume at the high point: Variable cost per unit Total variable costs at the high point Total fixed costs Total cost at the low point Variable costs at the low point: Volume at the low point: Variable cost per unit Total variable costs at the low point Total fixed costs
