Creating a variance column

Hi there, I am new to Domo and I have a question that I believe has an easy solution, however, I cannot figure it out. I have a table created to display Cost per load over the past three months. The formula for CPL is SUM(carrier pay)/ SUM(Loads). I want to have a column that displays the previous months CPL - Current months CPL and call it variance. I assume it requires a case statement stating if order ship date = previous month then previous CPL. However, I dont know how to write that.

Any advice or tips would be extremely helpful.

    @ColinHaze You can accomplish this using case statements inside your sums. The LAST_DAY function can be used to transform dates to the last day of the month so you can compare months.

    Current Month CPL

    sum(case 
  when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) 
  then `carrier pay` 
else 0 end)
/
sum(case 
  when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) 
  then `Loads` 
  else 0 
end)

    Prior Month CPL

    sum(case 
  when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) 
  then `carrier pay` 
  else 0 
end)
/ 
sum(case 
  when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) 
  then `Loads` 
  else 0 
end)

    Variance

     — Prior Month
   (sum(case 
    when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) 
    then `carrier pay` 
    else 0 
  end)
  / 
  sum(case 
    when LAST_DAY(`Date`) = LAST_DAY(DATE_SUB(CURRENT_DATE(),interval 1 month)) 
    then `Loads` 
    else 0 
  end))
  
-        

— Current Month
  (sum(case 
    when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) 
    then `carrier pay` 
  else 0 end)
  /
  sum(case 
    when LAST_DAY(`Date`) = LAST_DAY(CURRENT_DATE()) 
    then `Loads` 
    else 0 
  end))
