For middle-class people who prefer safe investments with guaranteed returns, the year 2026 has brought important financial changes.
One major reason is the Reserve Bank of India’s (RBI) repo rate cut of 1.25% this year. This decision has had a direct impact on the banking sector.
After the repo rate cut, most banks have started reducing their fixed deposit (FD) interest rates. This has made it harder for investors to earn high returns from bank FDs.
However, post office time deposit (TD) schemes continue to offer strong and stable interest rates, making them an attractive option.
Let’s take a detailed look at the interest rates offered by post offices and banks, and see where investors can earn better returns.

Special Advantage of Post Office Time Deposit Schemes
One of the biggest benefits of investing in the Indian Post Office is that its interest rates are directly controlled by the government.
Unlike banks, post office interest rates do not change immediately with repo rate fluctuations. This gives investors more stability and predictability.
Even after the recent repo rate cuts, the 5-year post office time deposit is offering a high annual interest rate of 7.5%.
Another major advantage is quarterly compounding, which helps your money grow faster compared to many bank FDs that use annual compounding.
In addition, post office deposits come with tax benefits. Investments in a 5-year post office TD qualify for tax exemption under Section 80C of the Income Tax Act, making it an excellent option for tax-saving as well as long-term wealth creation.
Returns on ₹1 Lakh Investment in Post Office FD
If you invest ₹1 lakh in a 5-year post office time deposit at an interest rate of 7.5% with quarterly compounding, your investment will grow significantly.
Total maturity amount after 5 years: ₹144,995
Total guaranteed interest earned: ₹44,995
This means your money grows steadily with zero market risk.
If someone invests a larger amount, such as ₹10 lakh, the returns are even more attractive:
Interest earned: ₹4,49,948
Total maturity amount: ₹14,49,948
These figures clearly show why post office schemes are preferred by conservative investors.
Returns on ₹1 Lakh Investment in Public Sector Banks
Public sector banks like SBI, PNB, Bank of Baroda (BOB), and Bank of Maharashtra currently offer lower interest rates on 5-year FDs compared to the post office.
Interest rate range: 5.00% to 6.40%
At the lowest rate of 5%, if you deposit ₹1 lakh in a bank such as Bank of Maharashtra:
Maturity amount after 5 years: approximately ₹128,204
At the highest rate of 6.40%, offered by banks like Bank of Baroda:
Maturity amount on ₹1 lakh: approximately ₹137,364
Compared to the post office, investors may lose around ₹7,000 to ₹16,000 in returns by choosing public sector bank FDs.
Returns on ₹1 Lakh Investment in Private Sector Banks
Private sector banks generally offer slightly better interest rates than public sector banks, but most still fall short of post office returns.
Interest rate range: 5.75% to 7.00%
For example:
A ₹1 lakh FD in CSB Bank at lower rates may grow to ₹133,036 after 5 years.
At the highest rate of 7.00%, offered by banks like IDFC First Bank and DCB Bank, the maturity amount can reach ₹141,478.
Even at their best rates, private banks still offer lower returns than the post office’s 7.5% scheme.
