we have built a list which lookups an amount in another table. This value is depending on other criteria in this list and we need to calculate a total. The output is hourly salary x hours worked. I know you need somehow a workflow but I cannot find a workable explanations of this formula. Anyone a clear explanation? Thx

I have added the formula now: enter image description here

But the result is zero: Postion2:NL is a lookup value Worked hours to charge is filled in field (default is 0) Vartotlhours is created Test is the output field in the list

What is going wrong?

  • Which value do you get from lookup? Salary amount?? – Ganesh Sanap Jan 16 at 6:35
  • Yes that is correct Ganesh – Remko Groot Jan 17 at 9:48


You can achieve this easily using Workflow.

You can implement one workflow on item created and changed events and calculate the output(hourly salary x hours worked) each time you edit the list item.


You can create a SharePoint designer 2013 list workflow on your list.

  1. Create two number fields NoOfHoursWorked and TotalAmount. Set default value of this column to 0.
  2. Create SharePoint designer 2013 List workflow on On Item Create and On Item Edit events.
  3. In your workflow use Calculate action to perform multiplication of NoOfHoursWorked and Hourly Salary.
  4. Update TotalAmount field with the result of the addition.

For Reference: See my answer and reference given in below link:

  • I have add the two colums in the list, but I am stuck at the second point? I can not find On Item create and edit? – Remko Groot Jan 17 at 19:24
  • See this image. There are the start options in the settings: i.stack.imgur.com/iXO5r.png – Ganesh Sanap Jan 18 at 0:29
  • I have added an example to my question as there is no output – Remko Groot Jan 18 at 9:59
