There are other benefits of opening a postal savings account. You don't have to lock up Rs 5,000-10,000 in maintaining an average quarterly balance. The post office does not mind if you have emptied out your account as long as you leave Rs 500 as balance.
This low-ticket convenience works in case of recurring deposits as well. If you open a recurring deposit with a bank, the minimum monthly deposit is Rs 500. In the post office, the monthly contribution can be as low as Rs 10, making it an ideal option to start your child on the savings habit. The 7.5% interest is compounded quarterly and compares well with what banks offer. The only hitch is that the post office deposit is for a minimum of five years. However, you can withdraw 50% of the balance after one year.
