Enter the tangible and intangible value to the community ($), the total time invested (days), and the total amount of money spent ($) into the SROI Calculator. The calculator will evaluate the SROI. 

SROI Formula

The following formula is used to calculate the SROI. 

SROI = (TV + ITV) / (T+M)

Variables:

  • SROI is the SROI
  • TV+ITV is the tangible and intangible value to the community ($) 
  • T is the total time invested (days) 
  • M is the total amount of money spent ($) 

How to Calculate SROI?

The following steps outline how to calculate the SROI.


  1. First, determine the tangible and intangible value to the community ($).
  2. Next, determine the total time invested (days). 
  3. Next, determine the total amount of money spent ($). 
  4. Next, gather the formula from above = SROI = (TV + ITV) / (T+M).
  5. Finally, calculate the SROI.
  6. 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.

tangible and intangible value to the community ($) = 50,000

total time invested (days) = 3

total amount of money spent ($) = 20,000

SROI = (TV + ITV) / (T+M) =  ?
