Frequently Asked Questions
When should I deposit money in PPF for maximum interest?
Deposit before the 5th of every month. PPF interest is calculated on the lowest balance between the 5th and last day of each month. If you invest annually, deposit the full Rs. 1.5 lakh before April 5th to earn interest for the maximum number of months.
Can I open PPF account for my child?
Yes, a guardian (parent) can open a PPF account for a minor child. However, the combined deposit in parent’s own PPF and child’s PPF account cannot exceed Rs. 1.5 lakh per year. The 80C deduction is also shared.
What happens after 15 years? Can I extend PPF?
After 15 years, you can: (1) Withdraw the full amount tax-free, (2) Extend for 5-year blocks without fresh contributions (existing balance earns interest), or (3) Extend with fresh contributions of up to Rs. 1.5 lakh/year. Extensions can continue indefinitely.
Can NRIs invest in PPF?
NRIs cannot open new PPF accounts. However, if you had a PPF account before becoming an NRI, you can continue it till maturity (15 years) but cannot extend it. The account becomes a resident account after repatriation.
Is PPF better than ELSS mutual funds?
PPF offers guaranteed 7.1% tax-free returns with zero risk — ideal for conservative investors. ELSS offers potentially higher returns (12-15% historically) with a shorter 3-year lock-in but carries market risk and LTCG tax. A balanced approach includes both: PPF for safety and ELSS for growth.
Disclaimer: PPF interest rate is reviewed quarterly by the government and subject to change. The calculations above assume a constant interest rate throughout the tenure. Actual returns may vary if rates change.
