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