Enter the total number of support staff and the total number of employees serviced into the Support Staff Ratio Calculator. The calculator will evaluate and display the Support Staff Ratio. 

Support Staff Ratio Formula

The following formula is used to calculate the Support Staff Ratio. 

SSR = SS / E * 100
  • Where SSR is the Support Staff Ratio (%)
  • SS is the total number of support staff 
  • E is the total number of employees serviced 

To calculate a support staff ratio, divide the number of support staff by the number of employees.

How to Calculate Support Staff Ratio?

The following example problems outline how to calculate Support Staff Ratio.

Example Problem #1:

  1. First, determine the total number of support staff.
    • The total number of support staff is given as: 15.
  2. Next, determine the total number of employees serviced.
    • The total number of employees serviced is provided as: 200.
  3. Finally, calculate the Support Staff Ratio using the equation above: 

SSR = SS / #E * 100

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

SSR = 15 / 200 * 100 = 7.5 (%)


Example Problem #2: 

For this problem, the variables required are provided below:
