Investment rules for Post Office Fixed Deposits
Jump Tag Icon

Opening a Fixed Deposit (FD) account with the Post Office requires customers to invest at least a deposit amount of Rs. 200. Additional investments can be made in multiples of INR 200. While individuals are typically restricted to opening only one FD account at a bank, they have the flexibility to open multiple FD accounts at post offices.

Post office FDs can also be opened in both public and private sector banks. One of the notable advantages of a post office FD account is the ability to transfer it from one post office to another. Withdrawal of the deposited amount is not permitted before the initial 6 months. After that period, premature withdrawal is allowed but incurs a penalty of 1%. Upon maturity of the FD, there are two options available:

  1. Renewal: The FD can be renewed for the same duration.

  2. Withdrawal: The FD can be withdrawn.

Post Office fixed deposits (FDs) are ideal for conservative investors looking to invest a substantial sum of money. The interest rates provided by Post Office FDs are occasionally higher than those offered by bank FDs. Moreover, investors have the option to request a loan against their FD from the post office.
