Perhaps something like this?
select sum(NetAmount) NetSale from sales
or you can just rewrite each result in terms of the sum:
select sum(NetAmount) as NetSale, format((sum(NetAmount)/4),2) as VAT,(sum(NetAmount)*5/4) as TotalSale
However, something like this should really be put into a stored procedure.
