Enter the effective stack size ($) and the flop pot size ($) into the SPR Calculator. The calculator will evaluate the SPR. 

SPR Formula

The following two example problems outline the steps and information needed to calculate the SPR.



  • SPR is the SPR ( )
  • ESS is the effective stack size ($) 
  • FPS is the flop pot size ($) 

To calculate the stack to pot ratio, divide the effective stack size by the flop pot size.

How to Calculate SPR?

The following steps outline how to calculate the SPR.

  1. First, determine the effective stack size ($). 
  2. Next, determine the flop pot size ($). 
  3. Next, gather the formula from above = SPR = ESS / FPS.
  4. Finally, calculate the SPR.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

effective stack size ($) = 300

flop pot size ($) = 10000

SPR = ESS / FPS = ?
