Let's use a car as an example. Say Peter's biz buys a car and he uses it. Is that an expense? Does the biz make less profit because of that car payment? Or is he just spending profit on it since it's mainly/entirely personal use? Not trying to get into a tax discussion but my point is profit can be massaged and is entirely subjective. Revenue is not. The money came in, or it didn't. Even in the US for single-job W2 employees, tax rates vary even by locality for folks at the same pay rate in the same company. So with identical pay, benefits, retirement savings, state and federal taxes, my personal take home pay is different than the guy next to me because we live in different townships. Same with business. Revenue is the easy number, profit is pretty subjective.

And by definition profit is a fraction of revenue. It can't exactly be more than 100% can it?
