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 Total cost at the highest volume Variable costs at highest volume: Highest volume Variable cost per unit Total variable costs at highest volume Total fixed costs Total cost at the lowest volume Variable costs at lowest volume: Lowest volume Variable cost per unit Total variable costs at lowest volume Total fixed costs High-Low method-Calculation of fixed costs
