FD is a very good option for investors. It is one of the most secure and reliable ways to save money. The money you deposit in the bank stays safe, and you also get good returns.

Punjab National Bank, the country’s second-largest government bank, offers an important FD scheme. The bank has announced that the fixed deposit interest rates have changed from September 1, 2025. After the new rates came into effect, many customers are asking about the interest they will get on ₹5 lakh FD, ₹7 lakh FD, and ₹10 lakh FD for 390 days. Now let’s look at the complete calculation.

PNB FD Interest Rate for 390 Days

An official source from PNB said that the interest rate on a 390-day FD is 6.60%. Senior citizens above 60 years get 6.90%, and super senior citizens above 80 years get 7.20%. These interest rates are fixed and guaranteed every year. So investors get a safe and assured return.

If a customer invests ₹5 lakh in PNB’s 390-day fixed deposit, the interest rate will be 6.60% per year. At this rate, the money will double in about 10.84 years (around 10 years and 10 months). This means if you invest ₹5 lakh today, it will become ₹10 lakh by 2036.
