I have some fd in HDFC bank on quarterly interst payout basis. When they pay the interst, a little amount is deducted from the interst amount. The deducted amount being Rs 25/30/50 etc proportionate to the total interests amount being paid.
I have fd with SBI and United Bank of India also but they never deduct any such amount like HDFC bank does.
Please note that I have submitted form 15g in time to them.
Can you please advise me how HDFC bank calculate the quarterly interst amount and is this normal?
