Facebook, which employed 20,658 persons in the past quarter - a 43 percent increase over the same period last year - made $188,498 (roughly Rs. 1.2 crores) per employee, according to a report in ReCode.
Microsoft made $52,400 (roughly Rs. 33 lakhs) and Alphabet $46,610 per employee - four times less profit per employee than social media giant Facebook - in the three months that ended on June 30.
Twitter, which saw a net loss of $116 million last quarter, lost nearly $36,000 per employee.
The reason for Facebook's efficiency is that software products do not require humans for the production and distribution process.
"Of course, even jobs formerly assigned to humans are coming under the purview of robots - so more industries could see consolidation of labour," the report added.
The research that was restricted to select major companies that have reported their employee count in their latest quarterly earnings, did not include Apple as they do not have a quarterly updated headcount.
