Volunteer Benefits Calculator

Your volunteering is worth more to WA than you think.

How are you estimating volunteer hours?

Weekly Monthly Yearly

Annual volunteer replacement cost: $0.00

Using the calculator

Enter the number of hours all volunteers work in your organisation by age cohort. If you are unsure of a volunteer’s age, enter their hours in the relevant “all ages” row.


*The replacement cost of a volunteer is calculated using the average hourly part-time wage of a person of their age in their State of residence, plus 15% employer on-costs (inclusive of superannuation, payroll tax and administration expenses).

The calculator uses the hourly rates as per the following table: 

Age cohort


15 to 25 years


25 to 34 years


35 to 44 years


45 to 54 years


55 to 64 years


65 years and over


All ages

What is 'replacement cost'?

The replacement cost of an individual's time is calculated with reference to the Australian Bureau of Statistics' 2015 data for Western Australia on the average part-time wage earnings of each age cohort, indexed for employer on-costs. This is added to the cost of relevant resources acquired by the individual in pursuit of their volunteering.

In other words, it is the amount of money a Western Australian business would have to spend to replace the overall contribution of the individual volunteer.

What is 'value'?

The value a volunteer-involving organisation delivers to the Western Australian community is a different measure to replacement cost. It aggregates the commercial, community and individual benefits created by each act of volunteering, and includes things like:

  • The employment and tax revenue created by the direct expenditure of individuals and organisations on volunteering
  • The costs avoided by civic institutions such as government departments of health, education, emergency services and the like
  • The productivity surplus enjoyed by employers as a result of their employees' volunteering
  • The wellbeing benefits returned to individuals and the community

You can use the replacement cost and value calculators interchangeably for individuals and organisations; however, the value calculator is not sensitive to age differences.
