Sum the total values of count

I know how to count or take sum but my question is different.

enter image description here

Above is my count list. I want to add up my all 3 column counts like 7+68+13....= sum

SELECT COUNT(DISTINCT od.`meter_serial`) AS 'OGP Created', 
COUNT(DISTINCT mp.`meter_id`) AS 'Installed & Un-Verified Meters', 
COUNT(DISTINCT ins.`meter_msn`) AS 'Installed & Verified', 
sd.`sub_div_code` AS 'SD Code',sd.`name` AS 'SD-Name'
FROM `ogp_detail` od
INNER JOIN `survey_hesco_subdivision` sd ON od.`sub_div` = sd.`sub_div_code`
LEFT JOIN `meter_ping` mp ON od.`meter_id` = mp.`meter_id`
LEFT JOIN `installations` ins ON od.`meter_serial` = ins.`meter_msn`
WHERE od.`meter_type` = '3-Phase'
GROUP BY sd.`name`

I want the sum of counts to be shown below each of the 3 columns while displaying count as-well.

Any help would be highly appreciated.

Either simply add the expression

COUNT(DISTINCT od.meter_serial) + 
COUNT(DISTINCT mp.meter_id) + 
COUNT(DISTINCT ins.meter_msn) AS total

Or make your query a subquery:

select
  "OGP Created", 
  "Installed & Un-Verified Meters",
  "Installed & Verified",
  "OGP Created" + "Installed & Un-Verified Meters" + "Installed & Verified" as total
from ( your query here ) q;
