# SUM Function: Calculate the Total of Numeric Values

Article Number:040807

You can sum numeric values by using the SUM function in a formula.
The SUM function can be used to sum the values entered in multiple "Number" fields, or to add up time data or numeric values entered in a table.

## SUM Function Syntax

``SUM(number1, [number2], ...)``

SUM functions need to have at least one numeric argument specified.
"Number 2" and additional arguments are optional.

For a numeric argument (e.g., "number1," "number2"), you can specify a numeric value, the field code of a "Number" field, or a formula that produces a numeric value.

## Formula examples

When specifying a field in a formula, make sure to specify the field code as the argument (and not the field name).
In the examples below, the field code is set for each field as the field name with underscores instead of spaces (e.g., the field code for the "Transportation cost" field is "Transportation_cost").

### Formula to Sum the Values of Multiple Fields
