Post office deposit: ₹5 lakh grows to about ₹6.18 lakh in three years

A ₹5 lakh investment in a three-year post office time deposit at the quoted 7.10% rate could mature at about ₹6.18 lakh, with quarterly compounding boosting the fixed return.

If you want a savings option that is not tied to stock-market swings and offers a fixed return, the post office time deposit could be worth a look. The scheme, often described as a post office fixed deposit, allows investors to lock money away for one, two, three or five years, with the interest rate varying by tenure. A guide from IndiaPost.org says the current rates run from 6.90% for a one-year deposit to 7.50% for a five-year term, while Policybazaar says those rates are in effect from 1 October 2026 to 31 December 2026.

For a three-year deposit, the appeal is straightforward. If an investor places ₹5,00,000 into the scheme at the quoted 7.10% annual rate, the maturity value comes to about ₹6,18,304, according to the calculation shown in the lead report and supported by online calculators that use the same quarterly-compounding method. That works out to roughly ₹1.18 lakh in interest over the term.

The compounding structure is one of the main features that sets the product apart from a simple savings account. According to IndiaPost.org and other rate trackers, interest is compounded quarterly, even though it is credited annually, which means the final payout reflects interest on interest over time. Fincalix and Accurio both describe the maturity formula in the same way and show similar examples for different deposit sizes and tenures.

The minimum entry point is low, at ₹1,000, and there is no stated upper limit on how much can be invested, making the scheme accessible to small savers as well as those parking larger sums in a government-backed product. IndiaPost.org also notes that the five-year deposit can qualify for tax relief under Section 80C, subject to the usual conditions, while the three-year option does not offer that deduction.

Investors should still check the fine print before opening an account. The rates can change, early withdrawal rules matter, and the tax treatment depends on the tenure chosen and the individual’s wider tax position. The scheme can also be transferred between post offices and extended on maturity, but the exact process should be confirmed with the local branch before money is committed.
