PPF Interest Calculation
PPF interest is calculated on the lowest balance between 5th and last day of each month and credited annually on 31st March.
F = P × [((1+i)^n − 1) ÷ i]
Where F = Maturity value, P = Annual investment, i = Interest rate / 100, n = Number of years.
Lock-in Period
PPF has a mandatory 15-year lock-in. Partial withdrawals are allowed from Year 7 onwards (up to 50% of balance at end of Year 4 or preceding year, whichever is lower).
Investment Limits
Minimum ₹500 per year. Maximum ₹1,50,000 per year. Investments exceeding ₹1.5 lakh do not earn interest on the excess amount and are not eligible for 80C deduction.
Extension Rule
After 15 years, you can extend in blocks of 5 years with or without contributions. Extending with contributions continues to earn interest and 80C benefits.
Where to Open
PPF accounts can be opened at any post office, SBI, or authorised nationalised banks. Only one PPF account per individual is allowed (HUF accounts are no longer allowed).

The current PPF interest rate is 7.1% per annum, compounded annually. The rate is set by the Government of India and reviewed quarterly. It has remained at 7.1% since April 2020.
To earn maximum interest, deposit your yearly PPF amount between April 1st and April 5th. PPF interest is calculated on the lowest balance between the 5th and last day of the month. Depositing before the 5th ensures that month’s balance earns interest.
Full withdrawal is only allowed at maturity (after 15 years). Partial withdrawals are allowed from Year 7 onwards — up to 50% of the balance at the end of Year 4 or the previous year, whichever is lower. Premature closure is allowed only in specific cases like serious illness or higher education.
If you fail to make the minimum deposit of ₹500 in any financial year, your PPF account becomes inactive. You can reactivate it by paying ₹50 penalty per year of default plus the minimum ₹500 contribution for each missed year.
Only one PPF account per individual is allowed in India. You can open one in your own name and one in the name of a minor child (as guardian). Having two accounts in your own name is not permitted and the second account earns no interest.
