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 ($) 
  • FPS is the flop pot size ($) 

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 = ?
