₹10 lakh in 3-year Post Office TD vs 5-year TD: Which earns more interest? Check out the calculations

The government has increased the interest rates for Post Office Time Deposits (TDs) for the July-September 2026 quarter. A deposit of ₹10 lakh will now earn 7.1% annually for a three-year tenure and 7.5% for a five-year tenure. This marks a notable rise from previous rates, making these government-backed savings instruments more attractive for conservative investors seeking capital safety and guaranteed returns.
For investors, the choice between the two tenures depends on liquidity needs and the desire for higher yields. The five-year TD offers a marginally higher interest rate, which can lead to greater wealth accumulation over a longer period. However, the three-year option provides better flexibility for those who may need access to their funds earlier. Both options are risk-free and come with the added benefit of tax benefits under Section 80C, provided the deposit is made through a Public Provident Fund (PPF) account.
Investors should consider their financial goals and liquidity requirements before making a decision. While the higher interest rate of the five-year TD is appealing, locking in funds for a longer duration may not suit everyone. It is advisable to compare these returns with other fixed-income options like bank fixed deposits or tax-saving mutual funds to ensure the investment aligns with your overall financial strategy.
