I use it for "what if" analysis. Well, I don't use those free calculators mentioned above, but I certainly do use an analysis tool that has a calculator built in. I don't use it to find theoretically underpriced or overpriced options.
They can be useful. For example in ¡what if¢ scenario Risk analysis. Visualizing PL scenarios with the passage of time. (Of course in this simple case you can make it without a calculator but things can get more complicated.)
