Definitely you can. You can even calculate exact balance along with interest on your pf account, as follows:
Take the closing balance (CB) of the last year, say 2008-09 and treat that as your opening balance (OB) for the year 2009-10.
You can cast OB & CB of each month as follows:
April 2010: OB (+) total subscription of the month (-) withdrawal (if any) = CB
May 2010: OB, i.e., CB of April (+) subscription of the month (-) withdrawal = CB
AND SO ON for every month up to March 2011
ADD all CBs of 12 months and DIVIDE by 12 = Average yearly CB at the end of March 2011
To this CB, multiply with the approved rate of interest/100.
Last CB + interest will be your balance for 2010-11.
Similarly, you can calculate for 2011-12 and onwards every year.
