CPA firm Quick and Associates' recent newsletter contains an article on calculating break-even sales and also cash burn rate. My first thought was that we all learned that stuff when we were in short pants, but maybe not.
One of the comments from analyst Mark Kalinowski's latest Owner/Operator survey (from a very experienced Owner/Operator) was:
"I find that most operators don’t understand the concept of Capex and think our cash flows are all ours."
A review of this very brief article might be worthwhile.
