The goal is to get the turnover % for a specific month of a year... so I have solved that by using 3 formulas... as shown below.  Is there anyway to combine these formulas to reduce the amount of formula fields??

Jan Count =
If ({DBHREMP.TERM_DATE} > Date (2011, 01, 31) or

{DBHREMP.DATE_HIRED} <= Date (2011, 01, 31))

and

{DBHREMP.TERM_DATE}= DateTime (2001,01,01) then 1 else 0

Jan Terms =
 If {DBHREMP.TERM_DATE} in Date (2011, 01, 01) to Date (2011, 01, 31) then 1 else 0

Jan Turnover %=
(Sum ({@Jan Terms})/(Sum {@Jan Count}))*100

Any help/ advice would be appreciated
