Calculated column using DAX

Hi, gandharv 

in above you mention price-cost  and you tack cost-price(f2-e2) 

so i take as a cost-price(f2-e2) so look at these

try below code with some changes

column= 
var a = tablename[model_run]
var b = tablename[category]
var c = tablename[time]
var e = tablename[date]
return
sumx(
  filter(
  tablename,
  tablename[model_run]=a && tablename[category]=b && tablename[time]<= c && tablename[time]=e
  ),
   tablename[cost]-tablename[price]

)
