A flow variable is a variable that measures a quantity over a period of time, whereas a stock variable is a quantity measured at a particular point in time. The amount of spending by consumers, the number of times a dollar bill is spent, and the number of shares of stock traded are all flow variables because they are measured over a period of time. The $100 Susan keeps in her purse is a stock variable because it is a quantity measured at a particular point in time.
