VELOCITY
VELOCITY is a measure of how many time the average dollar changes hands.
Here is an example of what would be personal velocity.
Suppose that your income = $24,000 paid in 12 monthly checks of $2000 each.
Suppose that you spend the $2000 over the course of the month.
Suppose that you always keep a $500 minimum balance.
Therefore, on pay day, your checking account balance would be $500 + $2000=$2500.
On the last day of the pay period, your checking account balance would be $500.
Your average cash balance would be $1500.
To put this in the symbols of the quantity theory, your PY = $24,000
your M
= $1500
So V= PY/M = 24000/1500 = 16
Now suppose the frequency with which you get paid increases to twice a month
rather than once a month. Your income is still $24,000. Your minimum balance is
still $500. Now you are getting paid twice a month, so each check is for $1000.
On pay day, you have $500 + $1000 = $1500.
On the last day of the pay period, you have $500.
