The Group Interest Calculation statement is a list of all accounts and sub-groups belonging to the selected group that displays the current balance in each account or sub-group and the total interest.
Go to Gateway of Tally> Display > Statements of Accounts > Interest Calculations > Group
Select a Group, Eg. Loans (Liability)
The Cr in the interest amount should not be confused to mean an Income. It only means that it is payable and is a liability.
To ease interest recording, Tally has an interest template, a special voucher class in Debit Note and Credit Notes.
