Enter the total volume of puts and the total volume of calls into the Put to Call Ratio Calculator. The calculator will evaluate and display the Put to Call Ratio. 

Put to Call Ratio Formula

The following formula is used to calculate the Put to Call Ratio. 

PCR = #P / #C

  • Where PCR is the Put to Call Ratio ( )
  • #P is the total volume of puts 
  • #C is the total volume of calls 

How to Calculate Put to Call Ratio?

The following example problems outline how to calculate Put to Call Ratio.

Example Problem #1:

  1. First, determine the total volume of puts. 
    • The total volume of puts is given as: 5,000.
  2. Next, determine the total volume of calls. 
    • The total volume of calls is provided as: 10,000.
  3. Finally, calculate the Put to Call Ratio using the equation above: 

PCR = #P / #C

The values given above are inserted into the equation below and the solution is calculated:

PCR = 5,000 / 10,000 = .50


Example Problem #2: 

For this problem, the variables required are provided below:

total volume of puts = 7,000

total volume of calls = 4,000

Test your knowledge using the equation and check your answer with the calculator above.

PCR = #P / #C = ?
