Posting its results late this afternoon at Recovery.gov, the White House claimed 640,329 jobs have been created or saved because of the $159 billion in stimulus funds allocated as of Sept. 30.

Officials acknowledged the numbers were not exact, saying that states and localities that reported the numbers have made mistakes.

So let’s see. Assuming their number is right — 160 billion divided by 1 million. Does that mean the stimulus costs taxpayers $160,000 per job?

Jared Bernstein, chief economist and senior economic advisor to the vice president, called that “calculator abuse.”

He said the cost per job was actually $92,000 — but acknowledged that estimate is for the whole stimulus package as of the end of 2010.
