Velocity of Money Calculator
Calculate the velocity of money — how many times a dollar is spent in the economy over a given period — using nominal GDP and the money supply.
What velocity of money measures
The velocity of money measures how many times, on average, each dollar in the money supply is spent on goods and services within a given period, such as a year. A higher velocity suggests money is changing hands quickly, while a lower velocity suggests it is being held or saved rather than spent.
The formula
Velocity is calculated using the quantity theory of money equation, M x V = P x Q, rearranged to V = (P x Q) / M, where P x Q is nominal GDP (price level times real output) and M is the money supply, such as M1 or M2. This calculator divides the nominal GDP figure you enter by the money supply figure to get velocity.
This is a standard macroeconomics formula provided for general education and analysis. Real-world velocity estimates depend on which money supply measure is used and can shift with changes in banking habits, interest rates, and financial technology.
