Totaling Three Columns for a Balance Column in a SharePoint 2013 List

Newish to SharePoint so, hopefully, I am explaining this clearly.

I want to build a simple Timesheet List where I have the following columns:

• Employee Name (Choice column, drop down of employee names)
• Vacation Start (Number column, is the number of total vacation hours a specific employee has)
• Vacation Taken (Number column, is the number of vacation hours a specific employee has taken)
• Vacation Earned (Number column, is the number of vacation hours a specific employee has earned per month)

I realize I can total these columns these by going to Modify View then the "Total" section in the list setting. And filtering by employee name...

But, what I also want is a column called Vacation Balance that would add all the total earned days (Vacation Earned) to the Vacation Start column then subtract all the total Vacation Taken days for each specific employee.

Example. Employee Alen has Vacation Start = 100 Vacation Earned = 8 Vacation Taken = 40

So therefore Vacation Balance would be 68 for Alen.

I tried a calculated column with =(Vacation Start + Vacation Earned)- Vacation Taken but the variable always shows a -variable for whatever shows in Vacation Taken.

Any suggestions? Thank you in advance.

• Is it shows -68 instead of 68? Can you also provide a screenshot of your formula? I have taken 3 columns of number types and created a calculated column with your formula It works fine. – Venkat Konjeti Jun 22 '17 at 3:35
• =SUM([Vac Start]+[Vac Earned])-SUM([Vac Taken]) – user24853 Jun 23 '17 at 13:19
• In the actual columns- For Vac Balance-- For the first entry, Vacation Start = 119 so Vacation Balance = 119 but when the second entry occurred Vacation Taken = 8 then the Vac Balance was -8. Third entry, no vacation was taken so Vacation Balance = 0. Then for the fourth entry, I entered 8 hours of Vacation Taken so that Vacation Balance = -8 (again). – user24853 Jun 23 '17 at 13:22
• This is my formula =([Vacation Start]+[Vacation Earned])-[Vacation Spent]. Try this it should work – Venkat Konjeti Jun 23 '17 at 13:28
• It's still giving me the Vacation Balance number as a negative number in Vacation Balance. =([Vac Start]+[Vac Earned])-[Vac Taken] – user24853 Jun 23 '17 at 13:39
