That value would put the price per square foot (5" by 5", or 25"sq) at somewhere around $800 annually, around 10x the general office prices for SF or NY. I'm guessing the $20,000 figure is the up-front cost of the entire office, plus furniture, technology, and any building out they did, divided by the number of employees. Which is misleading, since that cost is usually amortized over 5-8 years.

Or your company is really getting screwed.
