If a budgetary weighted average contribution margin (WACM) percentage has been developed with an expected level of revenue and a planned fixed cost and the budgetary WACM percentage is in fact achieved in the next (future) time period, could the organization still face losses if the total revenue drops below the budgeted level or total fixed costs increase beyond the budgeted levels? Can you explain how losses still might occur even though the planned WACM percentage is being realized in the future time period?
