calculate row wise total sum SELECT
 RegionManager,
 [Face-to-Face],
 [Phone],
 [Face-to-Face]+[Phone] as[Grand Total]
FROM
(select 
 ed.FRST_NM + ' ' + ed.LAST_NM AS RegionManager
 ,ACTVTY_TYP
 ,CALL_ID
 --,Month(CALL_DT) callmonth
FROM CODS_EDW.dbo.TERR_HIER th
LEFT JOIN CODS_EDW.dbo.[EMP_ROSTR] er ON er.[GEOG_ID] = th.GEOG_CD
LEFT JOIN CODS_EDW.dbo.EMP_DIM ed ON ed.EMPL_ID = er.EMPL_ID
LEFT JOIN CODS_EDW.dbo.[CALL] c
ON  c.TERR_CD = GEOG_CD + ' ' + GEOG_NM
WHERE th.SF_ID = 4
AND th.GEOG_LVL = 3
) source
PIVOT
(
    COUNT(CALL_ID)
    FOR ACTVTY_TYP
    IN ([Face-to-Face],[Phone] )
) AS pvtMonth
order by RegionManager


Using pivot i got result like this:

RegionManager   Face-to-Face    Phone   Grand Total
Craig Irwin     73  6   79
Holly Murphy    27  124 151
Julie Brown     37  28  65
Kevin Borth     52  35  87
Linda Krueger   46  23  69
Robert Bell     66  21  87


I want the output like below.(The columns might change dynamically, needs to calculate Sum by row wise)

Row Labels  Face-to-Face    Phone   Grand Total
Craig Irwin     73  6   79
Holly Murphy    27  124 151
Julie Brown     37  28  65
Kevin Borth     52  35  87
Linda Krueger   46  23  69
Robert Bell     66  21  87
Grand Total     301 237 538
you have to put your query in CTE for it you have to use  ROLLUP

;WITH CTE AS
(
-- Your Query
)


then 

SELECT
  RowLabels = ISNULL(RowLabels, 'Grand Total'),
  FacetoFace = SUM(FacetoFace),
  Phone = SUM(Phone),
  GrandTotal = SUM(GrandTotal)
FROM CTE
GROUP BY ROLLUP(RowLabels);


SAMPLE DEMO

declare @temp table (RowLabels nvarchar(max), FacetoFace int, Phone int, GrandTotal int)

insert into @temp values ('Craig Irwin  ',73,6  ,79)
insert into @temp values ('Holly Murphy ',27,124,151)
insert into @temp values ('Julie Brown  ',37,28 ,65)
insert into @temp values ('Kevin Borth  ',52,35 ,87)
insert into @temp values ('Linda Krueger',46,23 ,69)
insert into @temp values ('Robert Bell  ',66,21 ,87)


SELECT
  RowLabels = ISNULL(RowLabels, 'Grand Total'),
  FacetoFace = SUM(FacetoFace),
  Phone = SUM(Phone),
  GrandTotal = SUM(GrandTotal)
FROM @temp
GROUP BY ROLLUP(RowLabels);
