The worth people are talking about here is, for the most part, the market rate. If you don't own the business, your labor is fungible and the revenue you bring is not separable from the rest of the company, your worth based on revenue criteria like the one you mention is irrelevant and impossible to calculate, because part of the input is the system you're placed into and its cost is the profit deliverable to the owners. In general, the market does a better job of attributing how much of the profit is due to the capital, the system, the management, etc and how much is your contribution than any sort of ad-hoc, I produced X type of analysis. If that's not the case and your production is separable from the rest of the system, that does set a floor for your market rate because you can just do that on your own and keep the money instead.
