How much would it cost to design and build an Iron Man suit?

Iron Man's suit isn't as science fictional as you might think. Most of its components exist right now in research and development labs. What would it cost Tony Stark today to put them together and become superhuman? Helmet-mounted display Tony controls his Iron Man suit via a sophisticated helmet-mounted display that is voice-activated. It could easily be compared to helmet-mounted displays currently under development for fighter jets like the F-35. Fighter pilots use these displays to guide their aircraft the way Tony guides his suit. Last year, the companies developing F-35 HMDs announced they would be creating these helmets with a development budget of $54.1 million.
