Solution 1

Cast it as decimal(5,2)

declare 
	@v1 decimal(10,2),
	@v2 decimal(10,2)
	
set @v1 = 10000
set @v2 = 13500

select @v1 ,@v2 ,cast(((@v1-@v2)/@v2)*100 as decimal(5,2))

10000.00
13500.00
-25.93

Solution 2

Hi,

Check this...

SQL

Select 
value1,
value2,
((CONVERT(DECIMAL(10,2),VALUE1) - CONVERT(DECIMAL(10,2),VALUE2)) / (CONVERT(DECIMAL(10,2),VALUE2)))*100 as VALUE3 
from table1

Hope this will help you.

Cheers
