    Thanks Amit Bhai. It will be come more useful if you can club MIS + RD for 5 Years to get effective Yield OR FD + RD for 5 Years to get effective yield. In both cases the monthly or yearly interest paid will get credited to Post Office Savings account and after a gap of 3 days it will get transferred to RD automatically.
