The Public Provident Fund is a government-backed, long-term savings scheme popular for its "EEE" tax status — your contribution, the interest earned, and the maturity amount are all exempt from tax. It comes with a mandatory lock-in of 15 years, after which it can be extended indefinitely in blocks of 5 years, with or without further contributions.
How interest is calculated: PPF interest is computed monthly on the lowest balance between the 5th and last day of the month, but credited to your account at the end of the financial year. For simplicity, this calculator assumes the full yearly contribution is made at the start of the financial year and compounds annually — this represents the maximum possible benefit and is close to actual returns if you deposit early each year.
Contribution limits: You can invest a minimum of ₹500 and a maximum of ₹1,50,000 in a PPF account per financial year, and this combined limit applies across all your PPF accounts (self plus any minor accounts you operate). Contributions above ₹1,50,000 do not earn interest and are not eligible for tax deduction.
Worked example: depositing ₹1,50,000 every year for 15 years at 7.1% p.a. compounded annually grows to approximately ₹40.68 lakh, of which your own contribution is ₹22.5 lakh and the rest, about ₹18.18 lakh, is interest — entirely tax-free.
PPF also offers partial withdrawal facility from the 7th financial year onward and a loan facility between the 3rd and 6th year, making it more liquid than it first appears despite the long lock-in.

Yes, PPF enjoys "EEE" (Exempt-Exempt-Exempt) tax status — your contribution qualifies for deduction under Section 80C (Old Regime only), the interest earned is fully tax-free, and the maturity amount is also tax-free.
Yes, you can extend your PPF account in blocks of 5 years any number of times, either with further contributions or without. You need to submit an extension form within one year of maturity if you wish to continue contributing.
Yes, the government revises the PPF interest rate every quarter based on prevailing bond yields. This calculator assumes the rate you enter stays constant for the entire tenure, which is a simplification for projection purposes.
Partial withdrawal is allowed from the 7th financial year of account opening, subject to a cap based on your balance. Premature closure is allowed only in specific circumstances such as medical emergencies or higher education, and attracts a small interest penalty.
