A Term for Total National Corporate Income?

Apparently, there are different measurements of the national money supply. But in market terms, during a recession, money disappears not due to deflation (so much) as because it gets rerouted to savings, which shrinks the supply looping around between business->consumer/customer/investor->business. I’d like to know if there’s a measurement that tracks the quantity of cash in this loop. That is to say, all spending on investments and purchases in the US dollar marketplace.

Actually, it seems like what I want is probably the GDP but without government spending. Is there a source for the variables that go into computing the GDP? How finely (i.e. by week, month, year, etc.) can the GDP be calculated?
