Yes I know, you divided number one with number two and did the math right. I’m just saying that in the general world of business metrics comparing those numbers is not really a common practice.

Edit. For comparison, you might have a car that loses 5k of its value in a year and you work and get paid 50k a year. Surely that 5k depreciation is 10% of your yearly income, but typically you count that per cent from the value of the car instead.
