Example of Velocity of Money
Consider an economy consisting of two individuals, A and B, who each have $100 of money in cash. Individual A buys a car from individual B for $100. Now B has $200 in cash money. Then B purchases a home from A for $100 and B enlists A's help in adding new construction to their home and for their efforts, B pays A another $100. Individual A now has $200 in cash. Individual B then sells a car to A for $100 and both A and B end up with $100 in cash. Thus, both parties in the economy have made transactions worth $400, even though they only possessed $100 each.
In this economy, the velocity of money would be two (2) resulting from the $400 in transactions divided by the $200 in money supply. This multiplication in the value of goods and services exchanged is made possible through the velocity of money in an economy.
