What does the company get?

Jets costs are well within the millions and I was wondering what a company would get out a single plane that they sell? For example Boeing delivers a F-15E at a cost of around $60 M to the USAF, whats Boeings share ( the lions share off course 😀 )?

And what about jets that are made by several companies? Like the Eurofighter?

I have this feeling that no one knows due to secrecy of the companies, but I was just wondering.:D

Thanks
