Does your job create only one o/p file?

Total volume of what ?

Are all files retained after completion ? If not, do you want to include files that are job life only? do you need to include sortworks and other temporary datasets ?

Do you need to include all the input files that already have space allocated too?

The best you can do it guess... say for some reason your input record count triples... then your output datasets may triple in size. It won't be an easy thing to do.

The only truly accurate method for the temp files is by using SMF records to get the actual space allocated and used,

You can also use the same for the perm datasets.
