I guess I'm not explaining this too well. At the bottom center of the screen are 7 icons. The leftmost says "trains", next says "corporation", and 3rd from the left says "licenses." Click on "licenses" and another window opens. Right under the title are 3 choices, "auction", "soon", and "own." Click on "own" and your license will pop up. Top line lists what the license is for and how much extra it pays. Next line down says "costs." and the 3rd line down says "profit." This is the profit number I had a question about. I'm assuming that's just the profit from the license itself, but thought I ask a question and verify that.
I just got out my calculator and figured it out myself. That profit is just the money you've made from the license alone. It does not include the money you made for selling the good itself.
