If you need to quickly calculate your SAC Rate, use this calculator. You can also do it manually by following my guidance in my article on how to calculate your SAC Rate. This article also includes tips that will help you improve your SAC Rate.

This calculator will return two numbers:

  1. Your SAC rate in PSI/minute
  2. Your volumetric SAC rate in cubic feet per minute

Again, if you don’t understand how to use these numbers, read my article on how to calculate your SAC Rate.
