The Public Provident Fund (PPF) is one of India's oldest and most trusted government-backed long-term savings schemes, offering guaranteed, tax-free returns under Section 80C of the Income Tax Act. Because the interest rate is revised every quarter by the government and the contribution is compounded annually, working out exactly how much your money will grow to by hand can be tedious. A PPF calculator removes this guesswork - simply enter how much you plan to invest every year, the current interest rate, and your investment horizon, and it instantly shows your total investment, the interest you stand to earn, and the maturity value of your account.
A PPF account comes with a mandatory lock-in of 15 years from the date of opening. At maturity, you can choose to withdraw the entire corpus, or extend the account in blocks of 5 years - with or without making further contributions - to keep compounding your savings tax-free. This calculator estimates the maturity value over the standard 15-year lock-in based on your actual instalment amount, deposit frequency, and deposit timing.
The calculator follows the same rule PPF accounts actually use: interest for a given month is earned on the lowest balance held between the 5th and the last day of that month, at one-twelfth of the annual rate. A deposit made on or before the 5th starts earning interest that same month, while a deposit made after the 5th only starts earning interest the following month. This monthly interest accrues through the financial year and is credited (compounded) to the balance once a year, after which the next year's interest is calculated on the new, higher balance.
PPF enjoys "Exempt-Exempt-Exempt" (EEE) tax status, making it one of the most tax-efficient long-term savings instruments available in India. Contributions of up to ₹1.5 lakh per financial year qualify for a deduction under Section 80C of the Income Tax Act, reducing your taxable income in the year you invest.
The interest that accrues each year is completely tax-free and does not need to be reported as income, unlike fixed deposits or recurring deposits where interest is taxed at your slab rate. Finally, the maturity amount - including the entire principal and accumulated interest - is exempt from tax on withdrawal, whether you close the account after the 15-year lock-in or continue it in 5-year extension blocks.
