I have got a calculation written to calculate if a date has expired but I'm not sure how to calculate the amount of time that has expired??

My calc is

If ( renewal date ≤ Get ( CurrentDate ) ; "Expired" ; "" )

But how do I work out (in this instance) how many months have expired??

Thanks in advance

Depending on how what you want to see as the "Months"

this could be as simple as

(End Date - Start Date) / 30

Or this one that I borrowed from John Mark Osborne:

(Year(End Date + 1) -

Year(Start Date + 1)) * 12 +

(Month(End Date + 1) -

Month(Start Date + 1)) -

Case(Day(End Date + 1) = Day(Start Date); 0; Day(End Date + 1) < Day(Start Date + 1); 1; 0)

This calculation comes from a file by JMO that he sells at his web site (see the sponsors) and is well worth the price, as it has several good calculations. Link
