I just did the same experiment as you. I have the Macan S and all its options in a spreadsheet. I just put in the options for the Turbo. So, for the options I plan to get (most of them) I get a price difference of $10,500. I concur, the true cost of a loaded turbo vs. a loaded S (in the US) is about $10k for the extra 60 horsepower.
