I think your question is how to understand a PF slip received from the PFO to explain to your employees. First of all, please know that the PFO maintains a ledger for every PF account, similar to a bank account. Credits and debits are posted every month in this ledger. While credits that occur before the 5th of the month are eligible for interest calculation in that month, a debit even on the last day of the month is not eligible for interest in that month. The PF slip captures the gist of the ledger (OB, total credits, total debits, interest calculated, and CB).
I am attaching a model PF ledger, which is self-explanatory. The gist of transactions for the PF slip is shown at the end of the attachment.
Understanding Interest-Bearing Balance (IBB)
The essence for you to know is that the "interest-bearing balance" (IBB) is calculated every month. The total is struck at the end of the 12th month, and the average IBB is calculated by dividing the total by 12. One month's interest at the prevailing rate (9%) is calculated on this average IBB. If you have details of credits and debits, you can create a ledger and verify whether the interest shown has been calculated correctly.
Hope this will suffice.
