In today’s time, everyone is struggling with their increasing needs. Saving has become a big challenge amidst children’s fees, household expenses, and medicine expenses. To overcome these problems, the government has started many savings schemes, one of which is the Post Office Fixed Deposit. This is a scheme where you can invest your earnings without any worry.

What is a Post Office Fixed Deposit (FD)

Post Office FD, also known as Post Office Time Deposit (POTD), is a very safe investment run by the Indian Postal Department. It is an investment made for a fixed period, for which you get a fixed interest. Its biggest advantage is that it is backed by the Government of India, so there is no risk of money sinking into it.

How much return is available on an FD

After the amendment in June 2025, the interest rates on Post Office FD have been fixed from 6.9% to 7.5%. These rates are for tenures of 1, 2, 3, and 5 years. Senior citizens (above 60 years) get a maximum return of up to 7.5%.

Benefits of Post Office FD

Once the interest rate is fixed, it is not affected by market fluctuations. You can open an account with just ₹1,000, which is very convenient for small investors. A 5-year FD is eligible for tax exemption of up to ₹1.5 lakh under Section 80C of the Income Tax Act. The interest in this scheme is compounded annually, which increases your returns even more. You can easily transfer your FD from one post office to another. You can add a nominee while opening the account, which makes it easier for the family to get the money after you.
