Looking to calc the DOL, I'm supposed to calculate the difference between the sales and operating income for each year separately:
Year 1: sales of $25000 Year 2: sales $40000
variable costs of $13000 variable cost of $15000
Operating income $16000 Operating income $16000
So far I'm at a DOL of 1.71 for year 1, and 1.56 for year 2. Am I missing something by using contribution margin/operating income to determine the DOL?
