I on Humalog 75/25. 60 units twice a day. How do I calculate this myself?

Each pen has 300 units.  If you are taking 60 units a day, then 1 pen will last for 5 days.

With 30 days in a month and each pen lasting for 5 days, then you will need 6 pens in one month.

This has accounted for any losses of insulin, when priming the pen needles etc.  

hope this is helpful for you.
