FAQs Related to PNB PPF Calculator

1. Can I deposit money in a PNB PPF account online without having a PNB savings account?

No. Online deposits are available only when a PNB savings account is linked. This applies even when the account is opened through pnb ppf account opening online. Deposits must be made offline at the branch without it.

2. What makes a PNB PPF account better than PPF accounts in other banks?

PNB PPF accounts follow the same government rules, interest rates, and tax benefits as PPF accounts in other banks. The difference lies mainly in service features such as branch access, online facilities, and customer support, not in returns or safety.

3. What options are available after completing 20 years in a PPF account?

The account holder has 3 options after completing 15 years plus a 5-year extension. The account can be extended again for another 5 years with contributions. It can be extended without contributions while earning interest. Or it can be closed and the full amount withdrawn. A new PPF account can be opened only if the old one is fully closed.

4. Why is my PPF account showing zero interest even after many years?

This usually happens due to incomplete KYC, a dormant account, or incorrect account status in bank records. Interest calculation resumes once KYC is updated and the account is regularised. The interest is not lost but credited after correction.

5. How many times can a PPF account be extended after maturity?

A PPF account can be extended any number of times in blocks of five years after the initial 15-year maturity period. Each extension must be chosen at the end of the previous block, and interest continues as per government-declared rates.
