The numbers I'm looking at are the following: http://ir.tesla.com/secfiling.cfm?filingID=1564590-16-18886&...
As of March 2016:
$ 182,482,000 in Research and Development last Quarter.
$ 282,267,000 net loss in the quarter.
So even if we got rid of Tesla's ENTIRE R&D department, they lost $100 Million last QUARTER. The primary cost of Tesla is "Selling, general and administrative", which was around $300 Million.
The only other cost that's larger than their administrative costs were the $779,316,000 spent on parts.
#1 Cost: The parts (~$780 Million)
#2 Cost: Selling, General, and Administrative. $300 Million
#3 Cost: $182 Million spent on R&D.
These numbers are per quarter.
