I am new to Teradata and the Forum.

How can I avoid repeating the expression "100 * (curr_bal - cl_amt) / cl_amt" below?

     sel substr(date,1,7) Yr_Month,
         Svc_Ownr_Cd,
         Bucket,
         case
           when cl_amt = 0 and curr_bal > cl_amt then '(0)  CL=0 & Bal>CL'
           when curr_bal <= cl_amt               then '(1)  not OL'
           else case
                  when 100 * (curr_bal - cl_amt) / cl_amt <= 10
                         then '(2)  <= 10%'
                  when 100 * (curr_bal - cl_amt) / cl_amt <= 15
                         then '(3)  <= 15%'
                  when 100 * (curr_bal - cl_amt) / cl_amt <= 20
                         then '(4)  <= 20%'
                  when 100 * (curr_bal - cl_amt) / cl_amt <= 25
                         then '(5)  <= 25%'
                  else '(6)  > 25%'
                end
         end as OL_Pct,
         count(1) Number
     from  Table
     where ...
     group by 1,2,3,4

Thanks.
