Is it possible to populate a column with a sum of other columns in that same list item?

Question

I would like to have something like this, where AnnualSales is automatically populated with the sum of the four quarter sales figures:

Q1Sales     Q2Sales     Q3Sales     Q4Sales    AnnualSales
-------     -------     -------     -------    -----------
 123.12      234.23      345.34      456.45    =sum(Q1Sales, Q2Sales, Q3Sales, Q4Sales)

Is this possible with OOTB functionality, or must I find another way of achieving this?

Answer 1

According to your description, it seems you need to use a calculated column. The settings is like the screenshot below. In my test list, it works properly.

Answer 2

Please consider using a calculated column. You can either use the addition operator (+) or the SUM function. Please refer to this Microsoft article for details.
