You can display grand totals on a schedule, along with a custom title for the grand total, and a count.
Video: Calculate Totals in a Schedule
In the Project Browser, select the schedule name.
On the Properties palette, for Sorting/Grouping, click Edit.
On the Sorting/Grouping tab, select Grand Totals to display the sum of the elements from all the groups.
Grand totals also display the sum of any columns with subtotals.
Select a display option from the drop-down menu:
Title, count, and totals. Title displays the text from the Custom grand total title field. Count shows the number of elements in the group. Both title and count appear left-justified below the group. Total shows the subtotal below a column that can have a total, such as Cost.
Note: To show subtotals and totals for a calculable field such as Cost, make sure to select Calculate totals for the field on the Formatting tab. Because of the left-justified positioning of the title and count, if Calculate totals is specified for the first column in a schedule, the title and count will not display, only the subtotal.
Title and totals. Displays the text from the Custom grand total title field, and subtotal information.
Count and totals. Displays count values and subtotals.
Totals only. Displays subtotals only for those columns that can have them.
Optionally, in the Custom grand total title field, enter custom text to replace the default "Grand total" title. You can also clear the text in this field to display the total without a title.
