          I think this is technically more correct:

          365.25 / 7 = 52.178571429
          52.178571429 * 420,000,000 = 21,915,000,000
          (2,100,000,000 / 21,915,000,000) * 100 = 9.582477755
          

          Which means it’s 9.58% rounded down to 2 decimals.

          (This is using the common definition of a year and not a “tropical year”)

            Yes, but losing 10% of an asset typically refers to total asset value, not revenue.

              We’re not even including losses on the cocaine itself, this is all just about the revenue. He didn’t lose 10% of his business every year.

                I read it that he lost a significant part if his cash assets. Revenue is a different concept. In your calculation you made the comparison with revenue.

                  I compared the size of the two numbers I was given. I didn’t call them equivalent, I didn’t say they described the same thing. I only even used the word revenue after you did, because I was using zero context to compare the numbers (I just like numbers and it popped out to me that it was 10%)- it wasn’t until you said revenue that it occurred to me that he probably would have reinvested much of that money and it wasn’t just profit.

                  That said, now that I am thinking about it, he didn’t exactly have access to non cash investment or value storage options. I wonder if there was much of a difference between the total money coming in and the total cash coming in.

                    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.
